Actually, I was going to bring this up earlier. If you are trying to gain access to a data source from a remote client, you can't do that. Remote access assumes that all of the classes involved can be invoked remotely via some proxy. That might be true for the datasource class itself (I'm not sure), but I can almost guarantee that none of the JDBC classes (Connection, PreparedStatement, ResultSet) are accessible remotely. At least, that is my understanding. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3968241#...
