Recently I experienced some problems with OSB complaining about JCA class cannot be found. My SOA suite version is 18.104.22.168.
As I work on OSB JCA DB adapters, all of a sudden I see errors like the following:
Invalid JCA transport endpoint configuration, exception: javax.resource.ResourceException: Cannot locate Java class oracle.tip.adapter.db.DBWriteInteractionSpec
Invalid JCA transport endpoint configuration, exception: javax.resource.ResourceException: Cannot locate Java class oracle.tip.adapter.db.DBActivationSpec
This initially gives me the impression that someone touched the startup script that messed up the classpath. So I modified the startup script to hard code the jar files in the classpath. That didn’t really solve the problem.
After sifting through log files and comparing config.xml, I noticed that my OSB server is missing from the DB adapter deployment target list.
You can either edit your config.xml file to add it back in. Or go to weblogic console -> deployments -> DbAdapter -> Targets and make sure “osb_server1” is checked.
I think there is a bug that can cause this to happen. I don’t have an exact way to reproduce it. As you work on OSB JCA adapter services, this error may creep up on you.
