Glassfish DeploymentException: Error in linking security policy for

The same thing was happening to me.

Here is what I did:

• Stoped the Glassfish server
• Deleted all the content from glassfishhome/glassfish/domains/yourdomainname/generated
• Started Glassfish

It worked for me. But what still sucks is that everytime I need to deploy I need to follow this procedure again...

I will answer this in response to the comment of @SteveTaylor. His answer in the above comment helped me solving the problem, so he is the one who deserves the credits.

Original answer from @SteveTaylor:

The problem is a corrupt OSGi cache. The reason upgrading worked for you is because you started with a clean OSGi cache. All that's needed to fix this problem is delete the entire OSGi cache under $GLASSFISH_HOME/glassfish/domains//osgi-cache

This answer worked for me as well. Thanks a lot. I am using a cluster (Oracle GlassFish 3.1.2.2) consisting of two nodes and a domain server. I removed the OSGi cache under all three directories (2 nodes and domain) after I stopped the cluster and restarted it then. After that, the problem was solved.

It happen to me to, especially after I check out different version of my web application and try to deploy it to Glassfish.

The only certain solution I've found is to completely stop galssfish, restart it and deploy the application.

Probably a bug in the version of Glassfish I was using.

Basically changing to a different (later) version solved the problem.

In my case, I was missing @Stateless tag in one of my Managed Beans. Adding it, solved it for me. Hope it helps.
