How to disable the JSP validation in Eclipse helios?

I have a Maven project set up in my Eclipse Helios 3.6. It builds and deploys perfectly fine. But it shows a red mark on my project and shows a lot of JSP issues. I want to somehow get rid of these JSP validation issues in problem view. One example of JSP issue is ArrayList can not be resolved to a type. What I have done for this is inside window->preferences->web->jsp files->validation I have unchecked the validate jsp fragments Apart from this I right clicked On my project. Go to Properties->Validations then checked suspend all validator check box but stiil i see same issues in problem view and see red mark on my project?
