Last weekend my wife and I went to Olomouc, a small historical city and ancient Archbishop's seat in central Moravia. It's a UNESCO world heritage site, mainly due to its plague column on the Upper Square, which is the largest Baroque column in Europe. We prefer the 2001 turtle fountain (both visible in photo). Olomouc is very pretty and very quiet on weekends and only a 3 hr train ride from Prague (2.5 if you take the Pendolino, but I don't think it's worth paying almost double). When we went a couple years ago, the only foreign tourists were on tours organized by the Catholic church to see various regional sites of pilgrimage. Now however there were a number of what appeared to be independent family groups. This includes what to me were a surprising number of Americans, in that any Americans at all who weren't doing a year abroad at the University or taking a side trip backpacking between Vienna and Krakow would be a surprising number. Well, good for the city, I say, as the region is rather depressed and needs all the money it can get. One indication of this is that the city's tourist information office is open on Sundays--unheard of! As this was our third visit to Olomouc, we took a day trip to Kromeriz, where the archbishop of Olomouc had his chateau (38 mins by train, one transfer).
Amadeus was filmed at the chateau, and it is a really impressive building, with a surprisingly good gallery of historical paintings. Usually small city chateau collections are full of B-team C. European stuff that the noble family who owned them couldn't be bothered to take when they fled the country ahead of Communist state asset seizure in 1948 (or 1946 if they'd been bad boys in the war).

After the long, dank, grey Central European winter, Spring has arrived and with a bang. In the last couple weeks of April, everything flowered and all the leaves came out. True, I spent most of that time trying to get our new tutorials page nice and pretty, at least for web services. And then I was off to the Netherlands and Spain for 11 days, while everyone else was at JavaOne. (The Netherlands was great, and the weather really picked up after our first two days. On the other hand, while Barcelona is a great town, they had record breaking gales for two of the three days we were there.) But I'm back now, and it's May, which is my favorite time of the year in this country and this city. I have more pictures of Prague in general and Vinohrady, my neighborhood on my Photobucket account. You can also see some of my wife's knitting there...

- Download the Java version of the Interoperability Testing Tool from the WS-I.org Deliverables page.
- Unzip the tool into the location of your choice.
- Create a WSI_HOME environment variable set to the location of the unzipped Interoperability Testing Tool.
- Open the IDE and navigate to Tools > soapUI > Preferences. Open the WS-I Settings tab and, in the Tool Location field, enter the location of the downloaded and unzipped wsi-test-tools folder. Select other options according to your preferences and click OK.
To validate SOAP messages, first monitor a SOAP request and response, as follows:
- Find the binding node in the Web Service Tests node and expand it to show the requests.
- Right-click a request and open the Request Editor, described in soapUI documentation.
- In the Request Editor, send a request and wait for the response.
- Right-click in the response window and select Check WS-I Compliance.
You can see the test configuration used to generate the test report in the Config tab. SOAP message test reports also have a Log tab, which is an XML log of the request and response SOAP exchange.

Step 1: Download and install Axis 2. Well, that's easy enough, it's just a ZIP file. I see there is also a WAR file that I can download, but Step 2 is building the WAR file, so let's follow the engineer's directions and just download the zip and unzip it somewhere, say C:/ root.
Step 2: Run the build script in the Axis2/webapp directory to create axis2.war. Splendid, although there is no build script, just a build.xml. Wait, if there is a build.xml, then I can build it with ANT. Do I have ANT on my classpath? ... Nope. Have I installed ANT? ... Evidently not. So I install Jakarta ANT, put it on my PATH, and Bob's your uncle, or my uncle, or something. I wish I could write "...and Bob's your uncle" in an official tutorial. Anyway, ANT runs and I get my axis2.war file.
Step 3: Copy axis2.war to the J2EE server webapps directory. I copy it both to TOMCAT_HOME/webapps and GLASSFISH_HOME/domains/domain1/autodeploy.
Step 4: Start IDE.
Step 5: Install the Axis2 nbm plugin file. Milan sent me one as an email attachment, but the 6.1 distro I installed already had it as an available plugin, so that was easy.
Step 6: Go to Tools -> Options -> Axis2 -> Runtime and type in the Axis home directory. Easy enough.
Step 7: Still in the Axis2 Options, switch to the Deployment tab and enter the path either to the Tomcat Axis2.war or the GlassFish Axis2.war. I choose Tomcat since Axis is supposed to work a little better on that server. Milan's advise was to enter the path to the TOMCAT_HOME/webapps/axis2 directory, to which Tomcat unpacks the WAR, rather than the WAR file itself. However, I couldn't find an axis2 directory so just typed in the path to the WAR. Later I found out the significance of this absence...
Step 8: Enter the Tomcat Manager username and password. Fine, except that first I have to find out what they are. Milan said that they are in TOMCAT_HOME/conf/tomcat-users.xml, and he sent me an example of the file. It's a good thing he did, because my tomcat-users.xml is empty. I copy Milan's file into mine, and now I have Manager username "tomcat," password "tomcat."
Step 9: Create a new Java Library project. OK, I name it AxisBoldAsLove. Note to self: Do not make Jimi Hendrix references in official Sun tutorials. I create a myaxis package in the project.
Step 10: Create an empty Axis web service from Java in the project. I choose New -> Other -> Web Services -> Axis2 Service from Java and select "Empty Web Service" from the wizard. I put it in the myaxis package. Well, hurrah! I get an Axis Web Services tab in my project, with the NewAxisFromJava WS (hmmm, I should have selected a name), and the NewAxisFromJava.java class in my source package. Terrible name.
Step 11: Implement the service class. Well heck, I can't open the Axis web service, so I guess I should change the .java class. That however already has some "Hello, World!" output specified by default. Maybe I don't need to implement anything?
Step 12: Deploy the service. I right-click the service and select Deploy... OK, I get a BUILD SUCCESSFUL message, but nothing on the Tomcat log. That doesn't seem right.
Step 13: Check that service is at http://localhost:8080/axis2/services. Er, I have a 404 error.
OK, Milan's gone but Lukas Jungmann listens to my woes. We go through my project. And here's the nub: I should have copied axis2.war to the Catalina base, which is in Documents and Settings/Jeff/.netbeans, not to TOMCAT_HOME. Well, bloody hell, I copy it to CATALINA_BASE.
Still a 404 error! Lukas scries my log and sees that when I redeploy the WAR file, I'm still redeploying the one in TOMCAT_HOME. So we look at Tools -> Options -> Axis2, and sure enough, it's still pointing to the TOMCAT_HOME WAR file. So I change that, redeploy the service and generate a WSDL file.
Success at last! Everything is where it's supposed to be, and a JAX-WS client can be created based on the WSDL file.
Well, dear reader, by the time you see my tutorial this process should be simplified somewhat. Step 6 is already obsolete, because Milan has received permission to include the Axis libraries directly in our plugin. I'll try to play around with the service code a bit to see if I can make it do anything interesting, but really there's not much to it. All the operations appear to take place in a standard Java class, and that class is then exposed as an Axis web service. To change the operations, you change the java class and these changes are automatically reflected in the Axis web service. Milan's added subnode display to the web service in the project, so you can watch the operations get added to the web service in real time! After changing the service, you of course have to redeploy it, and then whoever is running the client has to refresh it.

The pink lump in my bowl was a big cake of fish roe. I don't know if it was carp roe, which I never would have thought about eating, but it was certainly edible, whatever fish it was. Probably carp just due to the size. I shared my roe with Eve, who never met a fish egg she didn't like. Note also the condiments on the table, including a bowl of crisp fried onion and hot pepper in oil (white bowl in background), which makes pretty much anything delicious.

That is Kocic, our miniature black cat. 6 years old and no more than 2.8 kg. That's just as big as she gets. She's a very affectionate and well behaved animal, except when she's hunting our toes, or when she decides to get our attention by sinking her fishhook-like claws into us.

Good news for those of you who have struggled trying to deploy the Getting Started with RESTful Web Services tutorial on the bundled Tomcat AS. No more digging about on netbeans wiki. I've combined the configuration instructions on the wiki with the existing tutorial, and created the new Getting Started with RESTful Web Services on Tomcat tutorial. The original tutorial is now titled Getting Started with RESTful Web Services on GlassFish.
We've been having some trouble building the new tutorial's project on linux boxes. These problems are related to known issues about library definitions on linux (Issues 126339 and 115947 for those of you in the NetBeans IDE community). If you have a linux box and use this tutorial, please let us know how it went.
For that matter, any and all feedback would be welcome!
