Exporting connection related classes

earnest.dyke May 21, 2012 11:15 AM

Greetings all,

Well, I got my JCA connector to work in EAP 5 and it's a thing of beauty if I do say so myself. My requirements have changed a little however and now I find that I need to deploy my JCA to AS 7. So I added the resource adapter config in standalone.xml and deployed and it seems to have deployed fine. When I deployed the web app that utilizes the JCA, I am getting NoClassDefFoundError exceptions on the connection classes. It appears that pre-AS 7 all of the classes in the .rar where available globally but now in AS 7 they are not. Is this observation correct? If so, what do I need to do to make my connection classes available to my .war? Do I need to bundle them into a jar and create a module for them?

Thanks in advance for any and all relevant responses.

Earnie!

Class loading is different, in AS7 nothing is global exported.
You have to set dependencies to each. See this documentation

Thanks for the response. This however only partially addresses my problem. I understand that class loading is different in AS 7 what I cannot determine from the documentation is how to define a dependency in my .war to the classes in the .rar. I tried adding Class-Path: deployment.XYZ.rar to my .war's manifest file but that did not work. That only looks in the deployment (in my case my .war) for the dependency and it obviously does not find it. Any more pointers for me?

Thanks!

OK. After re-reading the documentation Wolf pointed me to I was able to get this to work. So for future posterity, to reference other deployments from yours (in my case my .war needed classes in the .rar) add a Dependencies line (not a Class-Path line) to your .war's manifest.mf file and point it to your other deployment (in my case deployment.XYZ.rar).

I have hit the same issue, could you post a copy of your .war file's manifest.mf so I can see the exact syntax? Also, did you need to add anything to your .rar file's manifest.mf?

Thanks for the help.

Its

Dependencies: deployment.myeis.rar

in the .war's MANIFEST.MF. See https://docs.jboss.org/author/display/AS71/Class+Loading+in+AS7

Roland,

Of course Jesper is correct. Below is my manifest.mf. My .rar is named Trilogie-JCA.rar. The "deployment." on the front is how IronJamcamar makes it available to other deployments. org.infinispan and org.jboss.as.cmp are there because of other requirements within the war.

Hope this helps.

Earnie!
