All the server sockets ports are bind by the first instance. Why would you run several instances ?

Hi Micke,

was curious to know if its possible to run 2 instances of server.

I have a case where i have deployed 2 ear files. Each of them have an employee EJB and each of them have the same JNDI name for employee. So when i deploy both the ear's in the same server , it giving me JNDI name already bound error.

I dont have acces to the source code files and hence changing the JNDI mapping is not possible.

So i was thinking whether its possible to run 2 instances of the server. If i can do that, then i can deploy the ear's in diff servers, so that i do not get name already bound error.

If there's any other way of solving this issue, please do let me know.

Thanks

You can always hope that its the same class since they share name and jndi name. In that case you could just recreate the ear files without that class and move it to a seperate ejbjar/ear.

Thanks for ur response.

unfortunately its not the case, the classes,though they share the same name and jndi name they have different functionality, hence moving it to a seperate ear file will not solve the problem.

Hi,

Have a look at http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= have multiple instances of JBoss 3.2.1 running on a single server without any issues.

Please let me know if you need additional information,

Regards,
