I have two ear files. Each one with isolated classloader through file jboss-web.xml (<loader-repository>myFirstApp.package:loader=myFirstApp.ear</loader-repository>).
At the first ear I have a MDB. At the other ear I have just a simple jar inside lib directory.
I would like that the first ear (inside MDB) creates an object from the second ear through reflection API and call a method (If you think that is easier implement through EJB3, I can change it).
But one important requirement, I can't change my MDB when I add a second jar or ejb. Could you understand me?
Let me make a wild guess.
It looks like you already have both .ears using the same domain -- myFirstApp.package:loader=myFirstApp.ear.
Hence it should be possible to cross ref these classes, which confuses me even more ...
Sorry, I will try explain better.
Both .ears are using different domains: myFirstApp.package:loader=myFirstApp.ear and mySecondApp.package:loader=mySecondApp.ear.
My desire is that the my team develop just the secondApp, thirdApp and so on. The FirstApp will be a kind of framework that receive a jmsMessage and decide wich app execute. And each app has its own domain.
I would like access classes of other domain. Its better now or would you like more information?
Thanks for your help.
With JBossAS5/6 you can create a hierarchy of CL domains:
Perhaps having FirstApp as the parent to all others; SndApp, ThirdApp, ... could/would work for you.
e.g. FirstApp would hold the common classes, to exchange the data
But JMS is already a nice way to decouple apps, which you might just need to tweak a bit.
e.g. each app has it own queueu, where FirstApp just properly pushes it down the right queue
I am going to read the article now and see if it can help me. I have to understand better about the classloading.
Actually, nowdays I am using JMS to decouple apps, but I would like to create a framework to facilitate de development for my team. I don't want that they make "ifs" or use selectors, I would like a interface between JMS and the applications.
Thanks for your help. If I get any progress I update here.
