The GWiT Path

I have not been writing about this recently, but have been busy converting www.os-seilforening.org to Google Web Toolkit. It is progressing nicely, although there has been some stumbling along the road. Not due to GWT, but the server side integration with hibernate4gwt and gwt-sl. I turned out that hibernate4gwt did not support multiple hibernate sessionfactories. This has since been resolved, but I have not gotton around to try 1.0.4 version where the fix has been applied. I am still running on my own fixed version og 1.0.3. GWT-SL also had some minor issues, but they also have been resolved. As of now hibernate POJO's are travelling nicely back and forth. I have been doing some roundtrips on the design as I have progressed, maily refactoring stuff where I see that the copy/paste factor starts to get high. Also I have created a new maven project that obly contains GUI widgets that I feel are candidates for reuse.

Switching from JSF to GWT

After having given it a serious consideration, I decided to switch from JSF to GWT as the UI for my web-apps for the future. I have started converting a Strus 1.2 based application (www.os-seilforening.org) and removing the JSP layer. I initially started out using JSF (MyFaces/Shale/Clay) but have come to the conclusion that there are simply not enough working! widgets to justify the load on the server. One of the nice things that came out of that excercise was that I refactored out all the DAO and Buisiness logic from the Struts Actions. That meant that when I now am redoing the UI in GWT I can keep all that and just focus on the UI - Nice ! I'll come back we some writeup on my experience of the various component libraries Iaell be using to augment bas GWT soon.

eXtremetable vs Displaytag

Yesterday I stumbled upon a new JSP tag: eXtremeTable. This looks like an interresting alternativ to Displaytag. So this week I am going to give it a test run and see if it is actually a worthy aponnent to Displaytag. I am going to test features like paging, linking, special column content, export to various formats etc. I blog about what I found.

Maven-Proxy

Because we are behind a firewall at work and we also have a local repository here, I downloaded maven proxy to get around the issue of not being able to run with both internal and external repositories when you are behind a proxy. So with great enthusiasme I DROPped the maven-proxy war file into our local Tomcat. But no cigar. It did not even start up. Looking throgh the logs I found that the first issue was that the required maven-proxy jar file: maven-proxy-core-SNAPSHOT.jar was not included in th distro. Why on earth should this file not be included when all the other .jar files where there. So I downloaded the maven-proxy-core-SNAPSHOT.jar and DROPped that one into the WEB-INF/lib directory and tried again. This time a got en error stating that it could not load the IOUtility class. Further investigation showed that it was referring to the wrong package. So next step was to get the CVS head and build from scratch. Now that one was gone, but it was now complaining about some Velocity macros. So I took the ones from the CORE and DROPped them into the WEB-INF/classes directory and now that issue was fixed. The final issue was that it could not find the maven-proxy.porperties, so I searched for that one and found it learking in the standalone source. I DROPped that one into WEB-INF/classes and beeing a bit wiser I took a look at the web.xml file. Sure enough there was a referance to it there. So I altered the context-param so that it pointed to my maven-proxy.porperties, and finally I opened up maven-proxy.porperties and went through it to ensure that all the settings there where correct. Wham!! It started to work. If you are interrested, you can download it from here. Be sure to alter the web.xml file and also maven-proxy.porperties to suit your installation.

Back from Colorado Software Summit

Then this years Colorado Software Summit is over. As usual it was great, both seen from a professional view and from a social view. It was a long week of great intellectual input. Some of the most interresting sessions included Matt Raible's comparisons of web frameworks and Bruce Snyder's presentation of Geronimo. This year I also had the pleasure of being shaperon for two new CSS alumnimembers: Boerre Nordbakken and Thomas Bakke. Most enjoyable :). I was also pleased with the positive feedback on my presentations - thank you all attendents. Also a great thank you to Wayne & Peggy along with their family for taking the huge effort of arranging this great conference.
