[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Failed to retrieve stub from server

I initially posted this issue to the JNDI forum, then to the Clustering forum, but I can't get anyone to bite. Since the Hibernate people probably have run into this problem before, I'm resubmitting here in hopes that they have, or that they know the people who handle these issues. Here's the situation. We've had a web app that's been running fine on JBoss 4.0.5.GA, as the server-side for a Flex app. All developers are running JBoss AS's on their local machines and sharing a common MSSQL database. I built an MDB, added it to the deploy dir, and it worked somewhat with our web app, but the MDB couldn't find the FlexSession stuff. So we thought we'd build an .ear, to include the .war of the web app and the .jar of the MDB. The problem I'm getting on start-up isanonymous wrote : ... | 17:59:02 INFO [org.hibernate.util.NamingHelper] JNDI InitialContext properties:{} | 17:59:02 FATAL [org.hibernate.connection.DatasourceConnectionProvider] Could not find datasource: jdbc/PlanITDataSource | javax.naming.CommunicationException: Failed to retrieve stub from server 192.168.1.18:1100 [Root exception is java.io.StreamCorruptedException: unexpected block data] | ... Now, I never had this problem before, so something is not configured right, I guess. That IP address belongs to my colleague, who is running a clustered JBoss setup; I'm running non-clustered. (18 and 38 are the clustered AS, 14 is mine, and 30 is the data server.) He's also running Linux, whereas I'm running Windows XP Pro. He was able to get the app up and running, after wading through some configuration issues. We're on the same LAN, as are the other developers, who are only using the .war, not the .ear or .jar (MDB), and they don't experience any errors (all are on Windows boxes). Can you please tell me what's wrong with our set-up? Is there a way to make sure the clustered JBoss installation doesn't interfere with the non-clustered ones? I'm hoping that will solve my issue. Or maybe there's another solution. Thanks Pauly T. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056647#...
