Hi.
I'm attempting to use the FILE_PING discovery protocol in JDG 6.5 and have come across an issue.
I suspect this problem would, however, occur in any infinispan deployment in JBoss EAP where the following class from the app platform is invoked: org.jboss.as.clustering.jgroups.JChannelFactory.
In particular, the following code is found in JChannelFactory:
channel.setName(this.configuration.getEnvironment().getNodeName() + "/" + id);
The use of the "/" character in the channel name becomes a problem for the JGroups FILE_PING protocol where it uses this name to write a file to with node discovery information.
Because of the use of the "/" character in the filename, java bombs with an IOException: No such file or directory..
Stacktrace found here.
In run-times where JChannelFactory from the underlying app server is not used (ie: library-mode app deployment in stock JBoss EAP 6*) ..... FILE_PING protocol works well.
In that case, JGroups assigns a channel name that does not include a "/" character.
JGroups discovery info is written without issues to the corresponding files specified in the FILE_PING protocol.
