Welcome to me!

My name is Geertjan. I'm Dutch, raised in South Africa. Over the last few years I've been living and working in the Netherlands, Austria, then in the Czech Republic, and now in Amsterdam. I started working for NetBeans in May of 2004. I was a technical writer in the NetBeans Docs team in Prague, now a Product Manager for NetBeans. Before joining the NetBeans team, I worked as a technical writer for Coca-Cola in Vienna, Compuware in Amsterdam, Seagull Software near Rotterdam, and Four Seasons Software (which became SuperNova and was then taken over by WRQ in Seattle) near Utrecht.

Occasionally Asked Questions About Me And This Blog:

  • This blog seems to be all about "NetBeans". What kind of vegetable is that? Not a vegetable, my friend. Just the free and open source development environment, for programming languages such as Java, provided by Sun Microsystems. You can think of a development environment as being something like what "Open Office" or "Word" is to a writer of books or articles. Instead of books and articles, NetBeans is for writing programs, either for the web, for your desktop, or for your mobile phone. The generic term for this kind of tool is "integrated development environment" or, in short, "IDE". Find out more about NetBeans IDE here.

  • So where in the world are you, in real life? In Amsterdam, the Netherlands, after having lived in beautiful Prague, the capital of the Czech Republic, for several years, where NetBeans was originally created, in 1997. I've been part of the NetBeans team since 2004, now working from home in Amsterdam since 2010.

  • What is your official job at NetBeans? For the NetBeans open-source project, I am a product manager, after having been responsible for all documentation that relates to web services, NetBeans module development, and rich-client application development on the NetBeans Platform. (I also wrote a lot of the help files and tutorials that relate to web applications.) So, I'm responsible for the help file sections (choose "Help > Help Contents" in the IDE) for these areas as well as the on-line documents, such as quick start guides and tutorials.

  • Are you involved in other activities relating to NetBeans? Yes, I occasionally do presentations (like at Sun Tech Days, JavaOne, and NL-JUG conferences). I also contributed to the 2nd edition of the NetBeans Field Guide. And I contribute to some open source projects on dev.java.net, such as jMaki, BluePrints and NBWicketSupport. One thing I've really enjoyed is giving trainings on NetBeans IDE and on the NetBeans Platform, which I've done in "live" classroom settings as well as in on-line courses via Elluminate.

  • Do you have a recentish picture of yourself? Yes. Here it is:

  • Come on! Did anyone ever really ask the previous question? Well, no. I actually just needed an excuse to post my picture (because apparently that's the polite thing to do in a blog).

  • What's this blog about? I use this blog to record interesting new discoveries that I keep making while using the IDE. There've been so many times that I've thought, "Wow. This is really cool." But then a week or so later I've forgotten all about it because there's something else that I've discovered that is cool. And maybe someone out there will benefit from my discoveries. (By the way, this blog was inspired by my NetBeans colleague Roman Strobl.)

  • Is everything in this blog official gospel truth reflecting Sun policy and strategy? No. It is just my personal view on things. And you'll not find much on Sun policy and strategy here. It is all about NetBeans, how to use it, what it can do for you, some hidden tips and tricks, and my new learnings and insights. And they could all be wrong. Use at your very own risk.

  • What am I supposed to do with your blog? Read it and enjoy it! And ask questions when things don't make sense. Also, if you have anything to say about anything you find in this blog, or if anything is unclear in any way, either leave a comment in this blog or write to me at my personal e-mail address: g_wielenga@yahoo.com.

Hi, I am a Java developer keen to using NetBeans and I really think you're doing a great job with this weblog. There's one thing I couldn't find though (and I believe it is useful): an RSS/Atom feed for your weblog. Do you intend to provide one? Or is it there already and I just missed it?

Posted by Lucian Pintilie on May 25, 2005 at 01:16 PM PDT #

Hi Lucian. Currently I don't have an RSS/Atom feed, but I'm working on it. Thanks for liking the blog and please comment on anything that's unclear, or helpful, or worth commenting on. I'm just learning as I go along, so a lot of the things I'm blogging about are very simplistic and incomplete. Geertjan

Posted by Geertjan on May 30, 2005 at 02:58 AM PDT #

Hi Geertjan your weblog is very interessant for netbeans developpers. I am a student in intership where i must developpe with netbeans in Open IDE. Without your weblog, i was in difficulty to modify the platform. I didn't find any informations on netbeans in Open IDE except your weblog. So i really want to thank you to inform people in develop on Netbeans, don't stop helping beginners like me. Great job for you weblog.

Posted by Brennet Aurelien on July 04, 2005 at 06:21 PM PDT #

Thanks for your comments -- please continue reading and commenting this blog, it helps to know what people find interesting. There's actually quite a lot of information on platform development here:

http://platform.netbeans.org/

There are also several tutorials there and articles that you might find useful.

Posted by Geertjan on July 05, 2005 at 01:00 AM PDT #

We would've been collegues if I had accepted the job offer for SuperNova/Four Seasons back in 1997. :) It was /destiny/ that we met :-P I've put the netbeans kickstart up on the kickstart website and blogged (http://www.jroller.com/page/dashorst/20050718#7_minute_web_abs) about it. Thanks for your Wicket support!

Posted by Martijn Dashorst on July 18, 2005 at 09:10 PM PDT #

Hello Geertjan, I wonder if you could comment on whether I'm missing something or not: I have been trying to set up a free-form web app in NetBeans 4.1 so I can debug it. I have tried to follow the "official" docs on free-form but they seem to quickly depart from the samples. For example, linking Ant targets to IDE commands: there is no "install" for Run Target, "no reload", etc. I select others that look like they should work and I seem to work around these problems but by then the doc bears little resemblance to what I'm experiencing (for another example, everything seems geared toward TomCat instead of SunAppServer which I would have thought would be the case in the doc). Anyway, I can run my web app but it never debugs/stops on breakpoints. Do you have any thoughts on this? Thanks for your consideration. Dave Hunt

Posted by David Hunt on August 08, 2005 at 12:24 AM PDT #

This should help, it's in the FAQ (a pretty useful document once you know it's there):

Why can't I step into my source code when using the Ant debug target that I generated in the IDE for my free-form project?

About your other points, you should map whatever targets relate to project command to the related project command. I mean, of course not all free-form projects have a target actually called 'Install'. But, whatever the name of the target is that runs the project should be the one that you should map to the Run Project command.

Hope this helps, if not, please feel free to leave another message!

Posted by Geertjan on August 08, 2005 at 02:13 AM PDT #

Martijn -- sorry to have taken so long to reply to your message. Yes, it would've been cool to have met you at SuperNova/Four Seasons back in 1997. It was a really great company, a pity their marketing wasn't so good -- they just couldn't break into the US market (part of the reason was Forte, which became NetBeans, which is where I'm working now!). But it was a really great product that they made -- SuperNova (but a supernova is a star that rises quickly and then crashes, so they chose a pretty unfortunate name, I think)!

Posted by new2jwsdp on January 02, 2006 at 03:58 AM PST #

Hi new2jwsdp, you can't add a web service to the registry unless its been deployed. Seems like it hasn't been successfully deployed. Maybe you can't deploy because you're behind a firewall. If so, set proxy server and host in the Options window (under the Tools menu). I'm on vacation at the moment, I suggest you write to nbusers@netbeans.org if you continue experiencing problems.

Hello Geertjan, may you should update this page, especially the part: "... Compuware in Amsterdam (they produce OptimalJ, which is built on top of NetBeans)...". If you take a look on their page you can read: "The OptimalJ Developer Edition Built on Eclipse..." (http://www.compuware.com/products/optimalj/4480_ENG_HTML.htm) regards

Posted by Christian on March 14, 2006 at 11:22 PM PST #

My sources inside Compuware tell me that OptimalJ is built on Eclipse as well as NetBeans.

Posted by Geertjan on March 14, 2006 at 11:24 PM PST #

Hi Geertjan, I've made a couple of posts today on your blog (pdf and NB) and a question came to my mind...

About a year ago, I experienced a problem with JSPs in NetBeans 4.1, when they were not validating into NB (showing an error at status bar) but deploying right into the servers.

The problem was a duplicated library (commons-logging or log4j, can't remember) overriding NB internal bundled lib, distributed from the Visual Paradigm UML plugin.

The quizz is... a Sun employe at Prague contacted me via ICQ/Mail to resolve the problem, and I'm guessing if that person was you. I switched work and I lost my old-work ICQ/email account.

Just wondering, you know, curiosity is an evil enemy ;)

Keep doing good job.

PD: I'd have sent you an email asking but we have our internet access cut at office... blogs.sun.com is our only escape way in our daily duties :)

Posted by Juan Ara on May 25, 2006 at 01:25 AM PDT #

Hi Juan, nope sorry, that person wasn't me. I don't use ICQ/Mail at all. I just blog! Welcome to this blog and thanks for your comments so far.

Hello A really interesting blog and quite a lot of stuff about the Netbeans here. Great! Was searching around the topics to find more information about a specific Netbeans Component quite extensively used inside the IDE - The tree table view. 1. Do you have some tut's or some kind of a blog entry which actually talks about this? 2. If yes, have you talked about the column sort capability present in a TTV? Have tried posting this on the nbusers community but received no respose till now. Possible that you could probably help me out with this. I am at how to get this toggle feature work inside a TTV? ascending->descending->no sort. This seems to be implemented inside a TTV but then for an end-user to see it work - what does he need to do? enable something, set something, I dont know..... Thanks Pranesh

Posted by Pranesh on July 24, 2006 at 04:40 PM PDT #

Pranesh, good question. I've just begun using the TTV myself and don't know the answer to your question. But when I find out, I'll definitely blog about it! (And if you find out, please let me know!)

Posted by shansi on October 30, 2006 at 08:47 PM PST #

Not sure myself, shansi. I recommend that you write to dev@openide.netbeans.org and ask them this question. That mailing list is great, you should really subscribe to it and ask your questions there, because that's where all the NetBeans Platform experts send their questions and answers and that's where all discussions take place.

Hi Geertjan.. today i have attended your sessions at netbeans day, hyderabad. the developer collaboration module which you have shown was really interesting. and the pre-6.0 netbeans IDE was cool.. whole session has greatly influenced me to install netbeans immediatly as i came home.. but what really influenced me even more than that..is your blog. i have decided to start blogging.. though i might not post such great things like you do.. i will try my best to share all the things i know with people. it was a great day today. and your contribution to the climax made it possible. i will keep asking you all the doubts i have in java and netbeans (complex but not generic.. to save your valuble time) thank you so much.

Hi Lin Ye. Use 6.0, development builds currently available; that functionality (something similar to it anyway) is there out of the box.

Hi Geertjan, I played around with netbeans IDE 5.5 Everything seems to be running well till the point where my servlet call JSPs. the log shows the following message: WARNING: Servlet jsp is currently unavailable However, if I run the same code without using netbeans and shows the JSPs. The Test compile all JSP files during builds option was turned on and The JSPs class were generated. The servlet code failed at the point it try to call the JSP. (i.e. RequestDispatcher view = request.getRequestDispatcher("/result.jsp"); view.forward(request, response); I checked the HTTP monitor and I spotted one of the Context attributes entry (org.apache.catalina.jsp_classpath has a forward slash instead of backward slash) Could this cause the problem? If yes, how do I fix it? cheers

I start by clicking the big ad on the top of your blog site that says "Save 30%...Buy Now", but all I can do is read it online through the safari viewer. I cannot find a link anywhere on the page that mentions purchasing the hard copy of the book. Could you provide a link please, because I am obviously missing something. Thanks

Hi jay, I'm trying to work out the answer to your question. I went to that link and couldn't find the place to buy the book from either. Weird. I wrote to the publisher to ask them for help. Note that the book is also available on http://www.amazon.com/, just search for the title or the name of one of the authors. Thanks for your patience. Please drop me an e-mail (at geertjan.wielenga@sun.com) and I'll let you know the answer as soon as I have it.

This JEditorPane is used to edit beanshell code inside my application.

Hi Geertjan,
Trying to play with your mf files samples related to the GLF (Schliemann) I found that in the final release of NB6 there is a built in implementation (language.nbs) for manifest files that shows a syntax error in the key token. And the same happens with your sample... I guessed that the solution is to define an initial <DEFAULT> state for the token, and then the syntax error disappears...
Another question i'll be glad you should blog about is... is it sure to tweak the default nbs in order to provide .i.e navigation support for manifest files or other features?? WDYThink? Thanks

Hi Geertjan
Our company (SAAB Grintek) has recently selected the NetBeans Platform as our development framework, however everything we know of it has been through Internet research.
We were wondering what options we might have with regards to setting up a 'NetBeans Certified Engineer Course' in South Africa? Or if we would have to travel there for the course, or possibly an online course?

Any feedback would be highly appreciated.
Thanks
Khalil

Hi, really useful blog, I've been reading it a lot through my netbeans development. One question for you, do you know if it is possible to deploy an application via jnlp & also use the netbeans update center to deploy new modules. I haven't been able to get this to work.

Cheers,

Conall.

Hi Geertjan,

I don't know if you know about the NetBeans Innovators Grants [1]. But this would be a great deal for our project [2]. Now our project looks for a man who knows the details of NetBeans and could get into
1. the visual library
2. project API (e.g. 'new project' etc.)
3. beans binding
4. GUI (wizards etc.)
quickly?
Because we want to port the application with major enhancements.
Do you know somebody?
He will be even paid for this if we will be elected.
/\*
I guess you couldn't work on it, right?
\*/

Thank you,
Peter.

PS: Great work you did all the time with your blog. Really useful!

Hi!
All of your Blogs help me so much, Thank You!
There is one question i can not get an answer for.
Even on the NBusers Newsgroup i did not recieve an answer.
I am using NetBeans IDE 6.1 (Build 200804211638) on Windows Vista.

I created a new Model Suite with only the NB Platform Modules in it. Looks fine. But i want my Application to have a defined size and i want the Maximize Button of the Suite to be disabled. The User shall not resize it.
I can not find the right way to do this. Is there a property for this?
Again Thank You so much.
Dirk.

Hey Geertjan,
just one Question again. :-)

Is it possible to set the whole Mainwindow invisible? So that the only way to access the Applicationlogic is through a TaskbarItem? I know that this isnt really RCP but i like the NetbeansRCP mechanics so much, i would love to use them for this kind of project too.

Thank You
Dirk

Good Evening (Greece here) Geertjan,
you work over guidelines for NB and Java is really great. Most that i've read have to deal with Visual Library. Currently i am still an amature in this library. Im developing an application that uses ObjectScene to map object-widget data. All my needs are functional and operational. The las problem i have is that i cannot apply a Graph-like Layout to my Scene. Is there any other solution than using GraphScene (which is absolutely useless for my intent) or construct myself a method to set the PRefferedLocation of my objects-widgets?

Thanks for your generous Knowledge supplυ inside the blog. Hope you can help me now.
Thanks for your time.

HI Geertjan
I would like to know if you have topcomponent in a netbeans module , and this module you would like to use in more that one netbeans application.
I have a few popup menu options on this topcomponent that is visible in all the other netbeans apps , that is using this module.
If these "other" applications would like to add extra or new popup menus on this topcomponent in the NBM , is it possible?
Is it possible in such a way that it wont change / effect the NBM , that is used in the "other" apps?
So what i am asking is that can these extra popup menus be restricted to the NB app , and not be part of the NBM?

Posted by Theuns on October 21, 2008 at 04:45 PM PDT #

It's really well done

Posted by buy car on October 22, 2008 at 11:38 AM PDT #

Theuns, just create more modules, and then you will have more menu items. Each menu item could be in a separate module.

Hi,

We wanted to use javascript editor with Netbeans modules. Currently, the editor available with Netbeans6.1 does not show the core javascript commands unless its a Web Application Project. Kindly let us know how can we use the same in Netbeans Module.

Geertjan,

I have a fully self contained Wicket control that I developed, UIComposer, and I would like to contribute it to the Netbeans Wicket developer community in the form of a Netbeans plugin that will install itself into the Netbeans palate for Wicket applications.

I am currently hosting the project on Kenai at http://kenai.com/projects/uicomposer. I have to bring the wicket jars up to the latest release but otherwise it is fully functional.

So here's my question, would you consider including it in your next release of the Wicket plugin or is this not a good idea? I'd do it myself but honestly, I don't know how lol and there is no one else better able to do it than you are.

I hope you aren't offended by my proposition but I really want to contribute something back to the Netbeans Wicket community.

Hello Geertjan:

I´m developing a module for collaborative searching code in NetBeans IDE and the menu items that represents the TopComponent´s actions are always enable, I´m trying to enable and disable them for security reasons.
I was reading this page that you wrote http://blogs.sun.com/geertjan/entry/enabling_the_netbeans_platform_s about how to enable NetBeans menu items using CallbackSystemAction class, I would like to do something like that but with my own module actions. I implemented some actions classes but it didn´t work, it seems that I have to do something more for accomplish this functionality.
Please if you know the how of doing this, which classes should I use, I will really appreciate you could tell me.
Thanks in advanced,

[CSS Bug for [table of content] on the left side of your blog in Firefox]

Hi!

I didn't find a personal email address to write
you directly, so I'm using a comment. Feel free
to delete my comment afterwards.

First, thanks for your blog. It is always a pleasure to read it.

The left side of your blog, showing the "Table of
contents" is partly covered by the content area
in Firefox.
So I can e.g. only read
"Son, if you really want something in thi"
The rest is covered.

To correct that you have to change in your CSS:
#content {
...
margin: 5px 135px 5px 250px;
}

into sth. like
margin: 5px 135px 5px 350px;

For sure, there are other ways, perhaps better
ways, to correct that. This is an easy one.

Regards,
Bernhard

I was going through the sample on the NB Platform 6.9 Dev Guide, and on Chapter 2, where Forms are introduced, my NB 6.9 doesn't seem to work properly, in the beginning I've got this org.jdesktop not found, then I have added the swing-layout1.0.4.jar manually, re-did the process and even though the errors went away, Matisse was never executed, hence I couldn't edit the form.

Any ideas on this strange behavior (ah I forgot to mention that I had two JPanelDesktop Form on the menu, one just generates an XML file, and the other one generates a class, as expected).

Geertjan - first of all, thank you very much for your tutorials. As I am a new, young software developer, these tutorials are helping me progress very well.

I have a question pertaining to Visual Library, and its DnD capability.. I've followed your tutorial, and I've added some features of my own, and I am stuck on one last thing which I need to do...

I'm not sure if this is the best place to ask, but here goes nothing..

When I drag an object from the palette (which I've customly populated using the same implementation methods as you did in the tutorial, but with different organization and such), the image which that object has in the palette follows onto the scene, but the name which it has in the palette is not.

For example, my palette has a section entitled "Triangles" and a section entitled "Circles". Each section is populated with objects which contain a triangle image or a circle image, and every triangle has the .setName("Triangle"). Likewise, every circle has the .setName("Cirlce"). When I drag onto the scene, the image follows, but the name doesn't!

What method do I have to create in my GraphSceneImpl class that can aid me in getting the name to follow onto the scene???

Please help with this issue, and thank you for your time!

Hi Geertjan,
I loaded a Map to the EditorTopComponent with the use of Geotools from shape files. The problem is that if the user clicks any other TopComponent the EditorTopComponent repaints itself. for smaller maps the issue is ok but with larger maps its taking too much time and because of that the map disappeared for some time.

Please help with this issue..

Hi,
I've read through lots of your blogs especially the nodes drag and drops between different views (listview, beantreeview, etc) and I have also worked through the tutorials to do with the same things. However I am stuck as I cannot drag a node from a BeanTreeView onto an empty listView. I have overriden the getDropType() and paste() methods on the root node and also set dragable and drobable to true on the listView. I am very stuck and have been for a few days now. I was hoping you had some advice or a pointer to a tutorial that I had not seen yet.

Thanks

Geertjan,
I've been working through your post about creating multiple files from one wizard (https://blogs.oracle.com/geertjan/entry/multiple_files_from_a_single), however I have not been able to determine where the "@Override
public Set instantiate() throws IOException { //etc"
part should reside.

When placing it in the package-info.java file, it creates conflicts with the template registrations (using the new method of template registration explained in another of your posts).

Where should that part be put?

Thanks,

Hi, Geertjan,

I've been trying to follow the instructions to make a NetBeans plugin with support for a new language on https://platform.netbeans.org/tutorials/nbm-javacc-parser.html. I believe you are involved with that tutorial. I completed the lexer tutorial first, and the parser tutorial continues without, as far as I can see, deleting or changing any files from the lexer tutorial.

Now, when I leave the jcclexer and lexer folders in the NB project, the parser works without problems, but when I test the plugin, as I open a file with a script written in this new language and remove e.g. the closing quotation mark from a string that is not supposed to exceed one line, an exception is thrown from the jcclexer.SJParserTokenManager class, instead of the normal red circle appearing in the "gutter".

Am I supposed to move the classes from the "lexer" folder over to the "parser" folder and remove both "lexer" and "jcclexer" folders? I've tried, but the lexer tutorial's SimpleCharacterStream.java replacement makes it a hassle.

Is there something I didn't understand?

Thanks,
H.

Posted by guest on April 19, 2013 at 01:14 PM PDT #

Why don't you download the tutorial source code and take a look there to answer your questions? Below the table at the top of the tutorial is a download link.

Posted by Geertjan on April 19, 2013 at 11:25 PM PDT #

OK, so I did, Geertjan. Silly me for not doing so in the first place.

... but then I find the exact same behaviour in your project. I run the project and open a project in the new NB instance (I open the same project, actually), then create a SJ file and add this line:

public String geertjan = "GEERTJAN";

... see some exceptions on my way, but the one that interrested me the most, was the one that comes when I remove one of the quotation marks around the string. And it... TA-DA, yes, it did turn up here too. (Sorry, didn't mean to make fun of you.)

So I'll just dig into it as best I can. Have to look closely at the exception handling. If you have any tips about particular places I should go looking for a good api description concerning this, I'll be happy to know. Otherwise, I'll make sure to tell you about my problem more in detail, and about my solution, once I have one.

And btw, I run 7.3.

Regards,
H.

Posted by guest on April 20, 2013 at 11:21 AM PDT #

Instead of digging in and doing the best you can, why don't you join the mailing list and simply ask your questions to the thousands of people around the world who are doing similar things to you? That's also a good place to share your findings, rather than in a random place in my blog.

Java itself is a TECHNOLOGY not only a language, which differ with the concept of programming........Indeed its a great job you have done.

Posted by guest on May 10, 2013 at 02:33 PM PDT #

Hi again

About the "new language" tutorial and my comments above:
The lexer, of course, must fail when it meets tokens that do not exist. So unfinished strings *are* errors. the trick is to add something like
TOKEN: { <UNEXPECTED_CHAR: ~[] > }
at the end of the javacc's .jj file. Dealing with unfinished strings will then be handled by the parser, which seems ok and correct. As a matter of fact, *any* token may be unfinished while we type them, so the lexer is best for already finished files, not for files we work on. Seems the Unexpected_char token is very much needed...
(This is of course a javacc related trick, and has nothing to do with the Netbeans tutorial. I found this tip on http://www.engr.mun.ca/~theo/JavaCC-FAQ/javacc-faq-moz.htm#tth_sEc3.19 .)

Also, a comment about the amendements you make to the JavaParser class on https://platform.netbeans.org/tutorials/nbm-javacc-parser.html#error-feature: there is no need to add the error handling instructions in the .java file, they are better off in the .jj file so that they will follow again once you make a change to the .jj file and rerun javacc...

Otherwise, thanks a lot for huge amounts of good reading in your blog, and sorry for bugging you here with questions that (obviously!) could be solved without your help...

Where can I ask any questions regarding any issue when using netbeans? I'm always getting messages similar to this when using netbean modules:

try-with-resources is not supported in -source 1.6 (use -source 7 or higher to enable try-with-resources)

I always have tried going around it by changing the code to work with -source 1.6, but I was wondering if there is a way to use the -source 7. I know this is not the forum to ask, but I just wanted directions for where to ask.
