Re: MVP : model and duplicate
My bad, you're right. I was confused and forgot about Serialization. Thank you for pointing it out !

MVP : model and duplicate
Hi, I have some troubles with MVP : as I have understood, the model should just be business objects which are present in a shared package, so client and server can access them from a GWT point of view. In a three layered application how do you not duplicate these business objects, while you have beans used in the business layer ? From what I understand they are the same objects but in two different layers, so we need two different classes. Where is my mistake ?

Re: Problem with Eclipse, Google plugin and WTP
Hey Rajeev, The WAR folder is set to WebContent. The box was checked, so I unchecked it, but it didn't change the fact the libs weren't copied/deployed correctly.

Re: Problem with Eclipse, Google plugin and WTP
Hi, That's what we did as a fix, but it's not the way it should work. Otherwise we have to copy libs each time we add some in our business project which is not the way to go imho.

Problem with Eclipse, Google plugin and WTP
Hello, I have troubles with WTP and Google plugin for Eclipse. I have one Dynamic Web Application Project, and I use GWT in this project. It's smart-ui. I have a Java Project which contains all business logic, it's smart- business : smart-ui depends on smart-business. All is correctly exported in Java EE Module Dependencies. Now I use WTP to deploy on a local JBoss, and all is working except one thing : the libraries of project-ui are not deployed in WEB-INF/ lib. The project itself is compiled, packaged and deployed in this directory. I have found after investigating several hours I can deploy correctly if I set in the Java Build Path (in Eclipse) the Default output folder to build/classes (and not WebContent/WEB-INF/classes). All libs are present in WEB-INF/lib. I can even set the folder to build/ classes for example, it works. Meanwhile I have a new error in my project : The output directory for the project should be set to /smart-ui/ WebContent/WEB-INF/classes smart-ui-gxtUnknown Google Web App Problem If I set the Default output folder back to WebConten/WEB-INF/classes, I don't have the error anymore but the libs aren't exported to WEB-INF/ lib. I think there are some incompatibilities between WTP and Google plugin there. Am I missing something ? Is this a know issue and does a workaround exist ? Thanks for helping.

Re: Google Plugin for Eclipse 1.3 Preview is now available
I got it working (Eclipse 3.5, WTP 3.1, GPE 1.3) and it's working fine except two things. - I deploy onTomcat, and the devmode tells me to use a bad url : http://127.0.0.1:/index.html?gwt.codesvr=127.0.0.1:9997, while it should be http://127.0.0.1:8080/test/index.html?gwt.codesvr=127.0.0.1:9997 - when I load the webpage or refresh it, I got a ton of error messages like this one : 18:46:54.380 [ERROR] [openpronos] Errors in 'file:/C:/OP/workspace/ test-core/src/main/java/org/zanton/test/business/ ClassementService.java' 18:46:54.450 [ERROR] [openpronos] Line 12: No source code is available for type org.zanton.test.exception.EmptyPronosticException; did you forget to inherit a required module? It doesn't prevent the page from correctly loading but it's strange. I looked at the launch configuration, and the sources are in the Classpath and Source tabs. Thanks for helping.
