Remote Client unable to get connection from a DataSource

[jlevine47]

I need to be able to access a DataSource from outside the JBoss JVM. I
coded <use-java-context>false</use-java-context> in the DataSource per the instructions in the wiki. The remote client can lookup the data source but fails when it tries to get a connection:

I have using the -Djava.rmi.server.hostname= property in my run.bat
and the java.policy file has
permission java.net.SocketPermission "localhost:1024-", "listen, connect, accept, resolve";

Any ideas?

Thanks,

Jason

For a year old post that wasn't even properly written? Probably not. Are you having issues with this feature in JBoss? If so, please post this again.

Yes I do have the same problem,
I am using jboss-4.0.4.CR2 the latest candidate release. I can tell you this seems to coming in an inconsistent pattern

The exception i got was

java.lang.ClassNotFoundException: com.mysql.jdbc.CommunicationsException

The above class is not present in the classpath. Place the jar containing this class in the classpath to resolve the issue.
