Hi, the JAR files in WEB-INF\lib are automatically added to the classpath, no need to add those to META-INF\Manifest.mf. As you are using EJB3, you don't need any deployment descriptors besides web.xml, if you use annotations. You might try to remove them all, just to check that no error in one of them breaks your app. You might post the relevant parts of your servlet code, which don't work. And what is the error message?
