RE: Re: Re: problem with restlet-gwt
Hi Neva, Thanks for the update. I finally took time to play with this sample project on my freshly reinstalled WinXP box. I was able to reproduce this weird timestamp issue. It may be due to GWT detecting a more recent version installed (GWT 1.5.3 in my case) than the one used to compile the project, triggering some kind of reset on the configuration files. I have added a 'web.xml.backup' file to facilitate restoring in this case and separated the launch configuration for Eclipse into two separate ones, one for Linux and another for Windows and updated the how-to steps on the page with things that need to be adjusted manually on Windows/Eclipse. I've also updated the build.xml file to use the good JAR name on Windows so it builds with no manual change beside the GWT_HOME variable and uploaded the new sample ZIP on the wiki for version 1.1 and 1.2 of Restlet User Guide.

Re: Re: problem with restlet-gwt
I was never able to reproduce the issue -- don't know about Thierry. If your web.xml has NOT been overwritten (refresh your resources in the IDE to check that it still contains the GwtShellServletWrapper), it happens for you consistently and you are able to do a web conference, feel free to email me personally so I can get eyes on the problem.

Re: problem with restlet-gwt
Hi Rob, thanks for your support. Unfortunatelly the web.xml has not been overwritten. I controlled it more times and it's ok. What can be wrong? Did you try the sample on windows? It seems like the gwt engine is finding something in the module. When we perform a gwt-rpc call, we have to add a servlet entry in the module and the gwt module in this way knows how to route the request. When we run the gwtshell under eclipse, I saw that it starts a tomcat instance. It also deploys the restlet resources there in order they to be found by the gwt engine? My question is does the gwt shell behave as a web container and deploy the resources (in the server folder) within it as we had created a web project and put the restlet based application classes within it? If I start the restlet TestServer component as a standaolne application and then run the shell again it complains of an already used address and so the server side should work well even if I can not see the TestServer's sytem.out statements in the console.
