"Hello everyone, after metro stack got discontinued and CXF becoming the de-facto stack for JbossWS, I'm missing the @HttpSessionScope annotation. Basically, it automatically adds the jsession id to every http response so sessions can be tracked as usual in HTTP. For instance, that allows one to carry CDI/Seam conversations over several WS requests, very useful for rich clients. I would like for something to be included by default in jboss ws to allow for the same level of usability. Right now, the only alternative is to manually fiddle with the webservice context and add the header yourself. Another level of automation would be a Message Handler of Interceptor to do the job. Any other ideas?"
