add Web-Inf/Classes to subversion?

I want to add the WEB-INF/classes to subversion, and detect  changes -to commit them- in that folder in Intellij IDEA. I'm not happy  with this workflow, but my work uses it in that way. Tortoise SVN  detects the .class changes, but IDEA only gives me the option to commit  .java files. How can I do that? (Sorry for my English)

Thanks
