eclipse

[hariharan]

I have and existing .war directory which contains a lot subfolders like WEB-INF and other stuff. I need to import this .war directory into eclipse and build and run it. I am getting import not resolved for all the custome defined class, though I have added the root folder of the class in the window -> preference -> java build path -> classpath variables. Is ter any other setting i shld make up to resolve these errors

the class files are within the .war directory and how do i import them... plz guide me for any tutorial to import existing directories to eclipse. I use JBoss server and mysql for db connection
