Including JAR files in Eclipse (App Engine) project

Question

I have been searching for a solution for this issue for multiple hours today and many hours yesterday so I decided to address it here, although it seems a stupid issue.

Answer 1

You are on the right track. Since the app when deployed to appengine is packaged as a war (web application archive), library jars need to be in WEB-INF/lib. You should ensure your jars are there and then add those jars to your eclipse build path. Try doing a "clean" operation on the project and re-building it to ensure the libraries is in the package.
