I'm pretty new to JBoss and all the code I have done was essentially on 4.2.3
Now I need to switch to version 4.0.5 because my code needs to be integrated to some other apps thats works only on this version.
So basically to test if my jar and war files are compatible without modification, I copied them in my deploy folder. When I put the jar in the deploy folder nothing happens. If I do the same on a 4.2.3 it is immediately recognized.
Do I have to make some configuration change inside JBoss or is there a config file that I should include in the jar for it to be taken into account ?
After searching I just found out that I need to use the jems installer to install a 4.0.5 version with ejb3 support.
Given that I might not have control on what version of the 4.0.5 is installed, might there be another way to pack my jar with the required ejb3 support ?
