Deploy old and new appliacation on the same server instance

[prasannabp]

Dear members,
We need to deploy my old and new version of the application on the same server instance with difference application context. After copying oldapp.ear and newapp.ear to the 'deploy' folder getting the below jndi error. Is there any configuration for this kind problem in Jboss.

Note: we can't change the jndi name as we are using class name as jndi lookup key and this is hardcoded in the code.

Unfortunately if you can't change the two instances to use different JNDI names I think your only option is to start two JBoss instances.

It's actually a JMX error. There ought to be a way to specify different ObjectNames for your EJBs. I would file a bug on this....

Thanks for your reply. This is a very crucial issue for me. Some more thoughts to different approches to my problem,

1. Changing jndi names: Multiple versions of the application will be running so I can't have different jndi names for very release.
2. Having mutiple instaces: Not at all possible as one day I will have control over instances.

If you get any hint/solution. Please keep replying to this message.

Thanx and regards,

i'de like to do something similar, but in my case i want to have multiple instances of the same application as we a providing our product as a hosted solution and having multiple jboss instances all on their own ip address would seam rather wasteful
