I have problem with my libaries (classpath) with IntelliJ 4.0.3. I added several jar files to my module libraries path. While IntelliJ build process (Build Module) can find these libraries OK and compiled successful, the IntelliJ editor (where I edit my Java files) does not know about classes inside these libraries. For example, even if I have servlet.jar in the libraries classpath, IntelliJ shows reference to HttpServletRequest in read (ie un-resolved symbol). Can anybody help me here ?
