Hi,
I dived into the code off the app server. This is the method from the
org.jboss.ha.framework.server.HAPartitionImpl wich is crashing :
protected void verifyNodeIsUnique (Vector javaGroupIpAddresses) throws Exception
| {
| byte[] localUniqueName = this.localJGAddress.getAdditionalData();
| if (localUniqueName == null)
| log.warn("No additional information has been found in the
JavaGroup address: " +
| "make sure you are running with a correct version of
JGroups and that the protocol " +
| " you are using supports the 'additionalData' behaviour");
|
| for (int i = 0; i < javaGroupIpAddresses.size(); i++)
| {
| IpAddress address = (IpAddress) javaGroupIpAddresses.elementAt(i);
| if (!address.equals(this.localJGAddress))
| {
| if (localUniqueName.equals(address.getAdditionalData()))
| throw new Exception ("Local node removed from cluster (" +
this.localJGAddress + "): another node (" + address + ") publicizing the same
name was already there");
| }
| }
| }
The bold line is the one causing the NPE. I suppose the localUniqueName
variable is null. What could be wrong in my setup?
Please help me. I have to be sure this setup is working for next friday.
Johan,
