Answer 1

Just verify again that you have added the junit jar file in portlet (use portlet-plugin.properties),stop the server delete the temp and work folder restart the server and deploy your portlet again,also if you are using classLoader in your code then replace it with "getClass().getClassLoader()" save deploy again and verify it.
