Yes. Some of the time the error did occur after redeploying. On occasions
though, after restarting JBoss, the error would also occur on the first
process that accessed the datasource from a cmt ssb. I would just have to
bounce JBoss again (sometimes more then once) to get the error to stop
occurring.
Once the application works (ie no errors on accessing mckoi the first time),
it continues to work fine until a redeploy or a restart of the server. The
occurrence of the error was intermittent between redeploys and restarts so I
suspect that the jvm caching you referred to certainly could be suspect
here.
I did just recently bundle the jdbc datasource jar inside the application's
ear file with the goal of the application being self contained in the ear
file. Before I had just copied it into the server target's lib directory.

Subject: Re: [JBoss-user] jboss-3.2.3: Classloader problem?
The exception means the classloader has been undeployed.
It no longer holds a reference to the repository
Did you redeploy something?
But something is holding a reference to the classloader.
It looks like you've hit the caching done by Class.forName()
in java 1.4 that breaks hot deployment?
This is especially annoying with the way java.sql.DriverManager
uses Class.forName()
In general jdbc drivers are not hot deployable.
