I had read about the test/debug page not working when configuring DWR with spring in this thread :
http://markmail.org/thread/mejilqhtztnqdsd6. I tried to test it myself anyway just to make sure. I can confirm what John Gordon said in this thread here :
http://markmail.org/message/46hqenkirszc3hys. The test page infact does not work however if you browse directly to the test page of the bean, it works.
I searched for the issue in jira using the terms "test page" but didn't find any hits so i'm reporting this now. I have also attached my configuration and a sample java file for you to test with. The java file is a little dirty and only the getStuff() method is exposed.
