Two clusters on same machine using well know addresses - is it possible?

Question

Hi,
I try to setup two clusters (each with two nodes) on the same machine and want to use WKA for both of them. For the first one I do not have problems and it starts normaly.
When I try to start a node from the second cluster I get this message :
2011-07-07 12:00:06.984/10.710 Oracle Coherence EE 3.5.2/463p5 <D5> (thread=Cluster, member=n/a): Service Cluster joined the cluster with senior servi
ce member n/a

tion: Failed to start Service "Cluster" (ServiceState=SERVICE_STOPPED, STATE_JOINING)
I have configured the "java.property.tangosol.coherence.wka.port" and "java.property.tangosol.coherence.wka1.port" to different values for the second cluster than the values of the first.
Fist of all is such setup possible?
Any idea why I get this error and what else I need to change in the configuration for the second cluster?

Hi,
Now it works for me. I think I was setting the WKA on too many places as the documention of the application I have is a little bit confusing.
First I have posted the WKA with java.property as it was specified in the documentation of my application to set them in the script that starts it. I have removed them from the script and used only the xml file to configure coherence.
I am not using the override file but rather change the WKA configuration in the jar file itself. For the real enviornment and not my laptop I will use it.
Also there were two coherence.jar files in my class path and the first one was common for the both clusters and the second one was different for each cluster. In this second one I was changeing tangosol-coherence.xml the logs were showing that the configuration loaded from and also in the classpath this second was before the other one . Maybe I was wrong so I have removed the first coherence.jar that was common.
Maybe the combination of those two things were the problem but now it works. Thanks for your comments.
