Is there a way to specify a specific JRE per an application deployed in JBoss? Our JBoss server is running on JRE 1.4. All of the current deployed applications are running on JRE 1.4. I want to deploy a brand new application that runs on JRE 1.6. Is there a way that the legacy applications can run JRE 1.4 and the new application can run 1.6 on the same JBoss server?
