Hi, I'm having a very strange behavior with a cluster. The main problem is that I have diferent datasources, that they appear to start correctly, when I try to use them I get a NullPointerException. There are some other strange things that occur: The first node starts without problem, no matter which one of the node is. All the other nodes start with the following error at the end: 03:41:47,953 ERROR [URLDeploymentScanner] Incomplete Deployment listing: --- MBeans waiting for other MBeans --- ObjectName: jboss.mq:service=DestinationManager State: CONFIGURED I Depend On: jboss.mq:service=MessageCache jboss.mq:service=PersistenceManager jboss.mq:service=StateManager --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.mq:service=StateManager State: NOTYETINSTALLED Depends On Me: jboss.mq:service=DestinationManager 03:41:48,076 INFO [Http11BaseProtocol] Starting Coyote HTTP/1.1 on http-192.168.2.2-8080 03:41:48,231 INFO [ChannelSocket] JK: ajp13 listening on /192.168.2.2:8009 03:41:48,242 INFO [JkMain] Jk running ID=0 time=0/29 config=null 03:41:48,267 INFO [Server] JBoss (MX MicroKernel) [4.0.5.GA (build: CVSTag=Branch_4_0 date=200610162339)] Started in 27s:894ms I'm using jboss 4.0.4.GA, I became mad and tried 4.0.5.GA, I reproduced the same configuration but I got the same errors. The errors pasted above where taken from the 4.0.5 version. The permissions in files are all correct (99% sure) permissions to databases are all correct (100% sure). I'm using CentOS 4.4, and jdk 1.5.0 Thanks in advance, if you need more info to diagnose the problem, I'll post it. Excuse me if my english is not good.
