[JCA/JBoss] - Re: Classloading and sharing classes between .ear and .rar
by rupertlssmith
I should add, that that was the only way I could get it to work whilst using isolated classloaders for my .ear to solve the JAXB 2.0 problem. I think I managed to get around that one a differnt way and am not having to use the isolated class loaders now. So I should be able to deploy my .rar outside of the .ear too and not get class loader conflicts between the two.
I suspect JBoss needs to add a call-by-value mode switch for calling resource adapters? like it already has for making calls to EJB's that are not in the same .ear. This would be needed to call one that is deployed outside of the .ear when using isolated class loaders. I wonder if there is anything about this in the JCA specs? Haven't the time or inclination right now to go through them again.
My advice: Keep trying, this can be figured out. If you can't get it then post more specific details of your problem.

The .rar is not found if it is inside the .ear, no matter if the .rar name in the -ds.xml is qualified or not. However, with the -ds.xml inside the .ear and the .rar deployed separately, it is working again. Is there no way to deploy a .rar inside an .ear?
I have the -ds.xml and the .rar file in my .ear:
myapp.ear
|
|-META-INF/application.xml
|-index-ra-ds.xml
|-index-ra-0.2.rar
In the -ds.xml file I have the fully qualified name of the .rar file:
<rar-name>myapp.ear#index-ra-0.2.rar</rar-name>
In my application.xml I have the .rar named as a connector module:
module
connector index-ra-0.2.rar /connector
/module
(Please excuse the lack of angle brackets in the above XML, I can't get them to appear correctly and I'm not gonna spend all day finding out how to!!!)
Its been a while since I played around with getting this to work, but I think that is everything that is needed. I'm running JBoss version 4.0.4 GA and using the 'default' server setup to base my setup on.
I'm not 100% happy with this way of doing it because really I want to share my resource adapter between many .ears. Deploying it in the .ear as described above was the only way I ever managed to get it working.
Hope this helps?
