hi,

I am trying to deploy my code on liferay 6.1.2 ga3 and jdk 1.7( jboss apserver). I was able to successfully do this on jdk 1.6 with no issues, so then I tried to go to jdk1.7 based on this link :
http://www.liferay.com/web/james.falkner/blog/-/blogs/new-release-liferay-portal-6-1-ce-ga3

However, when I try to deploy any of my war files after deploying root.war, I get the following exception:

13:04:16,041 INFO [stdout] (com.liferay.portal.kernel.deploy.auto.AutoDeployScanner) 13:04:16,040 INFO [HookAutoDeployListener:50] Copying hook plugin for C:\programs\EAP6jdk71014\liferay-portal-6.1.0-ce\deploy\abc-hook-6.1.1.1.war

I am not sure what is happening, or how to solve this. Can anyone help me?

Thanks.
