Hello, I continue my investigations of Restlet : it sounds very promising but I encounter few problems with the demo project of the GWT edition : http://wiki.restlet.org/docs_2.0/13-restlet/275-restlet/144-restlet/188-restlet.html It is not possible to propose this framework in a professional project if we do not manage to put on the demo, i really hope that someone has a suggestion.
Here are the 2 points : 1/ if you replace the R2.0rc3 Restlet server jar located in war/WEB-INF/lib with R2.0.0 ones, then the json test no longer works (and work again if the jar are downgraded to 2.0rc3) The warning are at the end of the post [1] 2/ when running the application (with R2.0rc3 jar), everything works fine, nonetheless there is a warning about the WAR connector : "ATTENTION: No available client connector supports the required protocols: 'WAR' . " Complete warning further [2] Any idea ? Incompatibility between the demo project (testGwtRestlet-2.0) and R2.0.0 ? Thank you, my analyse is stuck by sand dust and this is quite frustrating since I have great expectation for this framework.
