1. By default you have commons-logging.jar in your {jboss.home}/server/default/lib directory. Leave it there and the exception will be gone. Same for javax.servlet.jar. 2. When you create your Java project in Eclipse, create your source directory in /src and your output directory in /build. In that case the code will generate correctly.
