Look inside your agent's log file, you will probably see more information. I suspect you will see this:
IllegalStateException: Failed to create backup directory: ...
But that's just a guess. We'd need to see the agent logs to be sure what's going on.
For background, when you deploy a bundle, the RHQ Agent will write some metadata to the deployment directory (called .rhqdeployments). If, during a deployment of a bundle, some files need to be backed up and moved out of the way, they will be stored under some subdirectory under that metadata directory.
I suspect the problem is the RHQ Agent no longer has write permissions to that file location?? Again, that's just a guess, but the agent logs should give more info.
Thank you for your response. Your assumptions were correct. I've gotten passed the error. I granted permissions throughout the jboss EAP directory and that fixed the problem.
