I’m currently using Vaadin with Eclipse Keplar. Everytime I load the src branch in the J2EE perspective i get the error:
‘Loading descriptor for ’ has encountered a problem.
I’m using servlet 3.0 and the problem seems to occur as there is no web.xml. If I add a web.xml, the problem goes away. However I understand servlet 3.0 shouldn’t require web.xml
I don’t know what is the exact problem you’re encountering. Servlet 3 requires a server that supports it, so it would be good to know which server and which version you are using.
It might also be helpful to get more details about the error (stack trace or something).
