web.xml errors migrating application from Eclipse

Hi,

I'm new to IntelliJ and migrating a web project that was built in Eclipse. I think I almost have this in a working condition but I get errors on the web.xml. Specifically, the error page definitions, the error pages themselves cannot be resolved and this is stopping the launch. For example there's an error page defined:

400 /destinationFinderPage.jsp ]]>

and I get the error:
Cannot resolve symbol standardError.jsp

My thinking was that I did not set up the context root correctly, I thought I had recalled specifying that somewhere while creating the project but I can't seem to find anywhere to view or change this now. Any thoughts?

Thanks
