Multiple .ear files support in One Jboss instance

[udaydg]

Problem :

In my project i want to create multiple .ear files ( with same .jar and .war files wrapped in it. All EJB and web components are same across all .ears) . This is to enable one jboss instance to support multiple .ears for different clients who would have their own Data sources mapped to the respective .ears.

Questions
Can i have multiple .ears with same .jar and .war . When i tried it it threw Instance already exist exception. So what is a workaround to enable this or i have to change the descriptors in all bean declaration xml files..

Second question is how can i have two .ears with separate .jar and .war files with allowing .war and .jar files from each .ear have access to other .ears .jar and .war file( I mean files packaged in .jar and .war file)..


Thanks

The things to watch out for here are your jndi settings for your ejb's. These have to change for each ear otherwise you will get conflicts.
