Jira Plugin development | Servlet issue - spring

Question

I am a student working on developing a plugin for JIRA, and have been having trouble getting my servlet to read my html file. So now I wonder which annotations are right to use ?, and what dependencies?. I don't get any error messages, I just can't open the index.vm page.
Would really appreciate if anyone could take a look at my code that I attach below, or just help me find the right person who is knowledgeable in this area.
Thanks for the help // Rickard
