I have this strange problem at which I have spent stupid amount of time. To build my portlet, I haven\'t used sdk and I am using my own ant script do the job. It works all w
Late answer, but maybe it will help someone:
- just shutdown your server; - delete the portlet from the "webapps" tomcat folder; - you should delete "temp" and "work" folders content; - restart your server and deploy your portlet.
Everything should be OK. I do not know why this happens, but I encounter this problem many times and fix it with the same solution.
Bye!
