Hi all,

I'm not listed in people you would like to answer, but there is something that could be the main problem here.

In your URL, you use "source", so it is normal that you get the corresponding DRL in response :
String
content=client.path("guvnor-webapp-${project.version}/rest/packages/essaiRest/assets/tab2/source").accept("text/plain").get(String.class);

If you want the XML, ie the asset XML representation in the repository, don't use "source". I am not very sure of the correct URL to use, but according to http://blog.athico.com/2011/03/atompub-interface-for-guvnor.html, it should be the same, without "/source" at end, and then you should get the XML in the response. May be you should use "Application/XML" in the accept instead of "text/plain".
