AJAX and NetBeans - jMaki and ZK

Hi everybody,

Last Thursday I did a Tech Demo about developing AJAX web apps using the powerful NetBeans 6.1 at Federal University of Rio de Janeiro.

I started talking about AJAX and how it improves usability and creates user friendly interfaces for the Web. Many people thinks that having ajax apps will overload the server and network just because you have a prettier interface. People have the idea that how more sophisticated is the app, heavier it will be. AJAX shows that it's not true.

The division of concepts let the server deal only with the data requested from Javascripts at client side. The interface refreshing is done all by the browser. So, instead of sending full and big HTML blocks to the client each time he refresh or navigate to a different page, the server just send the information requested and the browser deal with page drawing dynamically.

A great doubt about developing an AJAX app is to choose a framework. I suggested 2!

First I talked about jMaki. (http://jmaki.com/)

I did a demo showing the features of jMaki framework and its cool plugin for NetBeans.

jMaki is a client-server framework that encapsulates many AJAX components from other frameworks in the form of a Widget. With the NetBeans plugin, it let you create your pages dragging and dropping widgets to your JSP. You only need to customize your page changing the CSS file as you like and choosing the best widgets to compose your web page.

To start learning about jMaki, I suggest these links:
NetBeans jMaki Introduction Tutorial
jMaki Screencast
To get a little more advanced learning, try this Another jMaki NetBeas tutorial with RESTful WS

Later I started talking about ZK framework to build AJAX RIA using NetBeans.
When a friend showed me ZK, I got really impressed. It's a complete framework and it let you develop your app programming only in Java.

Yes! All the server side AND the client side scripts can be written in pure Java language (sweet Java)! Check some videos and examples at ZK Home Page

I did a simple demo using ZK to build a Web Telephone List.

WARNING: I don't use a database on this demo, but it's just to leave things faster. On a real world implementation , you should really consider that, specially because ZK has great tools to deal with Database and Persistence. If you understand Brazilian Protugese, check this blog post.

Now let's start our demo.

First, install NetBeans ZK plugin:
There are 2 plugin options:
1. ZK Designer plugins for netbeans 6.1
2. REM for NetBeans 6.0

The first let you develop your ZUL web pages dragging and dropping the components into your xml, but the second one is the one with code completion and highlighting.

Actually, in a very near future they will became only one plugin. Stay tuned for next release of REM plugin because it will came with the visual ZK designer bundled too!

Download the plugin and install it on NetBeans through the Tools->Plugins window.

For my Demo, I chose the first plugin that let me create my pages faster using drag n drop.

So now, let's create a New Project.

1. Go to File -> New Project
2. Choose a new Web / Web Application
3. Choose a name for your project (like ZKDemo)
4. Choose your server (GlassFish)
5. Choose the framework you would like to use. Here you must choose ZK!

The project opens with two index files: the index.jsp and index.zul. Delete the JSP and keep the ZUL. ZK support JSP includes, but its main ajax components are arranged to compose your web page on a XML file called ZUL file.

The index.zul file comes with a simple window page like this:

Try some drag and drop with the ZK components of the palette and then Run you project to check some ZK features!! Not all the ZK components are already on the palette! To see a full list of ZK Components, check: ZK Explorer!

For our Telephone List project you will need this index.zul file.
Copy it's content on your index.zul.
You will also need the catalog.zul file that is included on our index.zul and the catalog.zs file that is used by the ZSCRIPT tag on the begining of the index.zul file.

Just save catalog.zul and catalog.zs on your project page at your NetBeansProjects/YourProjectName/Web folder!.

Then go to NetBeans and open the ZS file. Look! It's Java code! No Javascript in here :D! See that it does 2 imports:

import ufrj.zkdemo.Catalog;
import ufrj.zkdemo.Contact;

This classes need to be created! But it's quite simple! Remember that if you create your classes on a diferent package, you will need to update the ZS file with yourpackage.Catalog and yourpackage.Contact imports!

Download Catalog.java class.
Download Contact.java class.

And put them on your project's source code packages!

Now Run your application and enjoy your veeeery simple telephone ajax catalog! See that, since we are using Lists and a Map to store the data, every time you Refresh your Web Page, you will have your telephone data ERASED!! Yes, this is not a very useful Tel catalog, but I encourage you to improve this project using a Database! ;)

Cheers,
Jonas

Software Freedom Day Report!

Hi everybody,

I know I'm late. I should have written this post last week, but I was quite occupied and forgot about sitting and writing the blog post.

The SFD event on Rio de Janeiro was fine! We had an attendance of 36 people and many of them were excited about what the OpenSource could give them.

About 10 o'clock of the morning we started the event speaking about the Software Freedom Day, Open Source and Sun intentions on this world! Next, we had a really great talk given by Magno Cavalcante, RioJUG's Leader and Sun Java Champion, about the Web 2.0 and people's value, including a lot of important concepts about software freedom, market and development.

After the lunch, we've kept talking about open source, showing great features of OpenSolaris 2008.05, VirtualBox and NetBeans. We explained the Sun Open Source University Meetup initiative to the students and invited them to join it! In the end, we had an OpenSolaris installation inside VirtualBox and we raffled give-aways!

Lots were said about the importance of software freedom! And how much the great companies support it, specially Sun!

That's it!
I will be probably posting something more technical here, like the SFD demo about NetBeans+AJAX that I have done.

Cheers!

Developer Web Days 2008

Hi everybody,

This Friday I will give a Tech Talk at Developer Web Days 2008 meeting, here on Brazil.

At 9:00 o'clock, I will be in Room A, talking about Web Development using AJAX and NetBeans:
I will give a little overview about AJAX and show how to easily construct and deploy AJAX content on your projects without Javascript, using the outstanding jMaki framework and the amazing ZK framework. I will possibly show the Dynamic Faces project with AJAX too.

at 18:30 o'clock, I will be attending Room D, talking about Service Oriented Architecture (SOA), Web Services and EJB. On this presentation, I will talk about how to support SOA with EJB, using them as web services and orchestrating them with BPEL, constructing your own composite application. Using the Open ESB SOA plugin for Netbeans, I will make almost everything visually, what makes it easy to understand and use later.

You can find more Information about the event at http://www.devmedia.com.br/webdays2008/index.html

After the presentations I will post the demos' Tutorials right here on this blog!! Stay tuned.

Cheers

Deploying Web Services on other Servers using NetBeans

Hey everybody!

A friend made a question on the WebServices and JSP on NetBeans 6.1 post about deploying Web Services on other servers, like Tomcat. It could be, actually, a problem, because many will say that you won't be able to deploy WS on Tomcat. That is not true. If you are using a version of JDK greater than 1.6.0_04, nothing needs to be done, you will just have to use TomCat on your project. If you are using older versions, you may check this link http://wiki.netbeans.org/FaqEndorsedDirTomcat.

I will do some demonstration here using Tomcat 6.0.16 that cames bundled with NetBeans 6.1 using JDK version 1.6.0_07 and JBOSS version 4.2.2 that I downloaded some time ago from www.jboss.org.

First, let's do our simple WS - that will receive a name as a parameter and return Hello name. Quite simple ;)
I will not get into details here because the other post has already covered the Web Service easy creation on NetBeans.
Just ask for a New Project on NetBeans (File->New Project or Ctrl+Shift+N). Select a Web Application, using the Web Category and press Next. Choose a name for your application (for example: HelloTom) and press Next again.
On this screen, you choose the server you will use for the project, select Tomcat.

Press Finish.
After project creation, right click the project name (HelloTom) and select "New->Web Service" from the drop down menu. On the wizard screen, define the Class and package name for your WS (like Hello and hello.ws). NetBeans will open your WebService for visual development.

Click on the "Add Operation..." Button. On the wizard screen, select the name of the operation (i.e. helloOperation). Do not use just 'Hello' as the name of the operation because it will be interpreted as the WS class constructor and you may get confused. Leave the Return Type as String but add a String parameter called "name". Click OK and see that the visual designer added your operation to the WS Operations list on the screen. Right Click the helloOperation and select "Go To Source".

On the Source edit the Operation code like this:

@WebMethod(operationName = "helloOperation")
public String helloOperation(@WebParam(name = "name")
String name) {
       return "Hello "+name;
}

Done. Now, right click your project name (HelloTom) and choose Run. If Tomcat is up and running, it will show the Hello World! message for you that is on its default JSP page.
The "Test Web Service" functionality we have used on the other post will not be avaiable on Tomcat like on Glassfish, but you can easily try your WS creating another project that access the Web Service on the server. If you have problems creating a project to access the WS, check the WebServices and JSP on NetBeans 6.1 post.

Now let's add another server to NetBeans and make use of it.

Click on the Services tab, on the left side of IDE. Righ Click the Server node and click on "Add Server..." just like the next picture:

The Wizard starts and you need to choose the Server type. Here, on my example, I chose JBoss Application Server (but there are many others):

Press Next. On the next screen, select the server location (ie, where is it installed) and press Next again.
On this screen, you will need to select a server configuration, I've just left the default:

Press Finish. The Server will be added to your Server list on the IDE. You may right click on its icon and Start the server just like this (Iniciar=Start, in Portuguese):

Wait until JBOSS starts and let's test it.

Go Back to your projects clicking on the Projects Tab. Right Click the Hello Project and select Properties from the drop down menu. On the Properties screen, select the Run category (that may be the last one) on the left panel just like the next picture (the picture has somethings in Portuguese where Run=Executar). After selecting the Run category, you will see (on the right side) the option to select the server where you want to deploy your project, we will have Tomcat selected, change it to JBoss Application Server.

Press OK and wait while NetBeans save your project's Settings. Now your can Run the Hello project again and it will be deployed directly on JBoss. The "Test Web Service" functionality is not avaiable on JBoss too, you need to create another simple project that access the Service on the server. It'easy and described on the WebServices and JSP on NetBeans 6.1 post.

That's it! There is no limit!
Cheers!

Self-Healing SAMP with OpenSolaris 2008.05 and it's SMF

Hi Everybody!

     Today I'm doing a review about the new OpenSolaris 2008.05, the one released from project Indiana on 05/05/2008.
     OpenSolaris 2008.05 has all the benefits of Solaris' Kernel and uses ZFS (the greatest file system of the planet) as its native file system. The first impression I had when I installed was its fastness. It's certainly much faster than Ubuntu 8.04, Fedora 9 and, of course, Windows. I'm using it now to do all my work and I'm really satisfied. See my desktop screen:

     OpenSolaris cames with Java installed, Firefox and ThunderBird, Pidgin, GIMP, eVince and many others Gnu Tools.The Flash plug-in is very easy to install, Firefox is prepared to do everything for you... so, no need to download it apart and then configure Firefox yourself to make it work. It just install and work for you.

     One of the greatest features of Solaris, for me, is it's Service Management Facility, aka SMF, that gives Solaris the Self Healing ability. Different from Linux, the services are not started and managed through the RC scripts manually, they are controlled by SMF, that manages dependencies, status, errors and organizes everything. If something goes wrong, SMF takes an attitude to repair the situation automatically. If it has no autonomy to full repair a problem, it gives great feedback, instructions about possibilities to fix the problem and very useful logs. OpenSolaris is smart!

     To challenge the OpenSolaris way of use, I decided to put a full SAMP platform to work on it, integrating that with Solaris SMF Self Healing System.

And the steps I followed to do it will fit on a single blog Post! ;)

     For those that are not familiar with some terminologies, SAMP means: Solaris+Apache+MySql+PHP ... a fast and furious development platform.

     The First Step was to install Apache, MySql and PHP. OpenSolaris cames with a Package Manager that downloads, configures and installs the packages for us, with no troubles and headaches about dependencies. Next is a screen shot:

     First, I searched for apache and asked the Package Manager to Install Apache 2.2 (SUNWapch22), FastCGI plugin (SUNWapch22m-fcgid), and PHP5 module for Apache (SUNWapch22m-php5). Second, I searched for mysql and asked the manager to install MySql 5 (SUNWmysql5), PHP5 Extension module(Core) to connect to MySQL database (SUNWphp524-mysql) and SUNWmysql-base. The last step was the search for php. I asked Package manager to install PHP Server 5.2.4 (SUNWphp524), Core components of PHP server (SUNWphp524core) and SUNWphp524usr.
     All the Packages are available on opensolaris.org repository.

     No headache to install SAMP. The three applications were installed on my system on /usr , /etc and /var directories separating (not that exactly, but...) executables/libs, configuration files and functional data, respectively.

     Then, I stepped to the interesting part: to configure Apache, MySQL and PHP to work together and to be part of SMF! I've started with MySQL.

     Created a my.cnf file at /usr/mysql/5.0 copying the my-small.cnf from /usr/mysql/5.0/share/mysql and renaming it:

# cd /usr/mysql/5.0
#cp ./share/mysql/my-small.cnf .
#mv my-small.cnf my.cnf

     Then, I've run mysql_install_db, running the script inside /usr/mysql/5.0/bin:

#cd /usr/mysql/5.0/bin
#./mysql_install_db

After that, just put mysql user as owner of /var/mysql folders:

#cd /var
#chown -R mysql:mysql ./mysql

     So, it was already possible to start MySQL through '/usr/mysql/5.0/bin/mysql_safe &' command. To stop MySQL, we may use 'pkill mysql'. I did it to test if everything was going OK. Then I configured Apache to work with PHP.

     First, I've edited the httpd.conf file on /etc/apache2/2.2 . I've searched on httpd.conf file for ServerName and ServerAdmin variables. I've left the ServerName variable set to 127.0.0.1, but it can be changed to an specific server name. Then I changed the ServerAdmin value to a valid e-mail.

     Next, I searched for <IfModule mime_module> tag on httpd.conf. And, Near the following lines:
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz

I've added a third line with: AddType application/x-httpd-php .php

It stayed like that:

AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php

     That's all for httpd.conf. Now, there is only php.ini left. I've just copied /etc/php5/5.2.4/php.ini file to /etc/apache2/2.2/:

#cd /etc/apache2/2.2
#cp /etc/php5/5.2.4/php.ini .

And then opened it to edit. I've only needed to find the block:
;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;

And add the following line after the comments:
extension=mysql.so

     So far so good. Everything is configured and working. You can try starting apache through '/usr/apache2/2.2/bin/apacheclt start' and use a little PHP script to test (Start MySQL too). Create a file with these lines:

<?php
     echo "Hello World!
";
     $conexao = mysql_connect('localhost', 'root', '');
     echo $conexao;
?>

and save it inside /var/apache2/2.2/htdocs with a name like myTest.php . Then, open your browser and type "http://localhost/myTest.php" . Apache and MySQL should be running (you may check it using the 'ps' command)! The Browser should display a message like:

     You may see I haven't configured a password for MySQL root user! That's really bad for a real system! You may change root's password on MySQL and create other users to use the databases as you need. But my intention here is just testing.

Now Let's put Apache and MySQL inside SMF!

     To set up a service inside SMF you need a script that knows how to start and stop your service (like the old rc scripts of linux) and a XML manifest file that gives more information about the service to SMF like dependencies and other characteristics. There is not so much headache to create these files. The Method script, as I mentioned, is not very different from an RC script, and for the XML manifest, that could sounds more complicated, there is a tool on opensolaris.org that helps you to generate your manifest file automatically, have a look at EASY SMF - http://es.opensolaris.org/easySMF/.

     Anyway, Apache and MySQL are famous services and, because I was in a hurry, I've just searched the Internet to see if there was something already done. And there it was. I've edited the scripts and manifests files from these links to put my services under SMF management.

http://systemsadmin.info/solaris/articles/setting-up-smf-for-apache-and-zope-on-solaris-10
http://www.sun.com/bigadmin/content/submitted/mysql_smf_tip.html

Thanks to Chris Miles and William Pool for the files!

     I've had to edit the original method scripts and manifest files because many installation details were different from what I found on the originals, like the paths to many important files. So I've adapted them to work directly for OpenSolaris Package Manager Installations.

     So, you can have the method scripts here. Just copy them into /lib/svc/method :

Apache Method: apache2
MySQL Method: svc-mysql

>> After saving them on method directory, chmod them into 555 permission (read and execute) (( '# chmod 555 apache2 svc-mysql' ))

     And here are the Manifest Files. They will be copied into different directories:

Apache2 Manifest: apache2.xml

>> Save it inside '/var/svc/manifest/site' directory and chmod it to 444 permission (read only) (( '# cdmod 444 apache2.xml' ))

MySQL Manifest: mysql.xml

>> Save it inside '/var/svc/manifest/network' directory and chmod it to 444 permission (read only) (( '# cdmod 444 apache2.xml' ))

Good. Now the last step. Import them into SMF through the commands:

# svccfg -v import /var/svc/manifest/site/apache2.xml
# svccfg -v import /var/svc/manifest/network/mysql.xml

If you have Apache2 and MySQL running on the system, turn them off (you may use 'pkill mysql' and 'apacheclt stop'). To start your services, now you may use:


# svcadm -v enable apache2
and
# svcadm -v enable mysql

and

# svcadm -v disable apache2
and
# svcadm -v disable mysql

To turn them off.

     It's possible to see their status through the command:

# svcs -a | grep apache2
# svcs -a | grep mysql

(svcs command list the enabled services; -a option show all the services, enabled and disabled ones)
You may see if there is any problem with your services running the following command:

# svcs -x

If something weird makes your Apache or MySQL go down killing their processes (try it yourself), SMF will take care of it and put the services up and running again!

Nice, isn't it?? And quite easy too!
That's it. Through few steps, now I have my SAMP platform configured and under OpenSolaris Self-Healing system.

Cheers!
Jonas

JavaME and WebServices Tech Demos

Hi all!

Last week we (me and Luiz Aquino) did great Tech Demos at NCE at UFRJ!
On Thursday, we talked about the Easy JavaME development with NetBeans. Because of the holydays, we had a not very high attendance of 21 interested people, including students and a professor.
On Friday, we talked about the Easy JavaEE WebServices development with Nebeans. We had a greater attendance of 29 interested people. It was nice and most liked the drag and drop style of constructing things on NetBeans.

The Projects of the demos are here:

The main WebService that offers the login, addUser and removeUser Operations:
Download

The GUI clients that offer interfaces to add users and to log in.
Download

And the Mobile Phone Project that offer the mobile interface to log into the server.
Download

One more thing!

NETBEANS 6.1 final release is now avaiable!!


have a look at:
http://download.netbeans.org/netbeans/6.1/final/

Now with Early Access to PHP out of the box too!!
And you may use NetBens only as a C or Ruby or PHP IDE... you don't need to have JavaSE module installed... anyway I strongly recommend using NetBeans for everything, hehehe! ;)

Cheers

Sun MD Earthquakes!!

Today was THE day of BLACKBOX TOUR @ BRAZIL @ Rio de Janeiro!
Just one thing to say! That thing is really cool!

For the ones who don't know about what I'm talking, it’s about a complete Datacenter inside a container. The widely known project BlackBox has become a Sun product! They just (but not simply) put 8 racks inside a 20 feet container with exclusives refrigeration and amortization system, redundant power and data links… well, there would be many things to say. If you got interested by the specs. Have a look at Sun MD Data Sheet and get amazed too.

The nicest part! It’s totally moveable. You can take your Modular Datacenter Anywhere! For many industries, it fits perfect! You can have a "turn-key" datacenter while you builds your own. For example, about the discovering of a new oil bay, you can’t wait for 5 years till the end of a datacenter building… so… just take your Sun MD there!!

On the talk during the today’s event was said about a video hosted at YouTube about an experiment Sun did to test the black box… they put it to survive a simulated Earthquake! To the experiments, they used the earthquake simulation system, cameras to visualize the container interior and SUN SPOTS to measure thinks! Yes, there were Sun Spots there… The video is amazing, and they have already used the experiment’s results to improve Sun MD performance…. But get shocked: Sun MD kept working after a 6.4 Richter magnitude scale earthquake. Have a look ate the video:

Want to buy one?? It could really stay on the top of your building and you can try it’s 450000 web transaction per second capacity:

3 of 4 Tech Demos are Done!

I would like to use here a new HTML tag: < WET >
Yes... you may read this post hearing water streaming...
Yesterday, the rain started before I woke up and (I hope) it will stop after I sleep. I almost started to search for Noe's arc.

The good news now!

Yesterday, we (me and Luiz Aquino) did our second Tech Demo on the Superior Institute of Technology of Rio de Janeiro. The institute is part of FAETEC (a foundation that supports technical education) and has a new and innovative model of teaching. The article I wrote (I posted it here, so you can read it. Just search below) to subscribe to the event were published on an eletronic magazine.
We made two Techs;

The first (on Monday): Innovating with Solaris and OpenSource Technology
It was great, almost 60 people. We got many interested faces and many questions. We talked about Entrepreneurship, bzness planning, IT and the advantages of OpenSolaris and OpenSource choices. We explained Solaris, its distributions and Project Indiana.
The professors got very excited about SAI (we talked about it too, of course) and we are sending them the e-mail with details and instructions about the academic initiative. We distributed Solaris Mini-Books and SXDE DVDs.

The second (on Wednesday): Java & NetBeans, practical development, robust solutions.
It was great too. Because of the rain (in one day, rained what should rain in 45), fewer people arrived for our presentation... about 30 to 40... but It was nice too. We explained about the importance of using OpenSource technologies, the Java Platform and the Amazing NetBeans 6.0. The only problem was that we had to do the demo on NetBeans 5.5 wich was already installed on the machine we were working on... but we talked a lot about the new features of NetBeans anyway. We gave Mini-Books for those who were not present on Monday and talked briefly about Solaris.

Now we will keep contact and make the effort about SAI.

At UFRJ, we did our Tech Demo about Solaris, Introduction and Installation, on last Friday.
It was cool too... we had and audience of 35 students, and many showed interest to join our OSUG, that is growing bigger with 12 members. We distributed OS Mini-Books and SXDE DVDs and got e-mails to add on our Sun@UFRJ mail list.

We are about to repeat this demo on this Friday!! Then I will report it again!

That's it! :D
