The portlets are not visible in Liferay

Hi!

I have liferay portal 6.0.6 bundled with tomcat. I've created portlets and packed them up in .war. When I'm deploying this is what happens in logs:

15:47:42,900 INFO  [AutoDeployDir:167] Processing alumni-ui-0.0.1-SNAPSHOT.war

It used to deploy correctly but one time it stopped and does not deploy any more. I've tried deleting directory from webapps and this is what I got:

INFO: Undeploying context [/alumni-ui-0.0.1-SNAPSHOT]
15:54:30,219 INFO  [ExtHotDeployListener:205] Extension environment for alumni-ui-0.0.1-SNAPSHOT will not be undeployed

SEVERE: The web application [/alumni-ui-0.0.1-SNAPSHOT] appears to have started a thread named [MySQL Statement Cancellation Timer] but has failed to stop it. This is very likely to create a memory leak.

I have also tried to unzip new lifray portal, delete the old one and do everything from scratch, but id does not work either.
I have also tried deleting everything from tomcat work folder and temp.

The moment it broke was adding maven dependency to portal-service.jar I think, but even when I stash changes and try to deploy old version it does not work.

What can I do more? Where to look for the bug? I'm out of ideas.

Thanks for any help.

The problem was lying in a way I declared dependency for portlet-service.jar - it was already in bundled tomcat and it was needed to add scope -provided to this dependency. Once tried to deploy incorrectly made .WAR the tomcat is trying to do something with this jar which was in .WAR once and has some problems.

Cheers!
