[jboss-dev-forums] [Design of JBoss Portal] - Portal clustering problem, a JBoss cache issue??

[michaelchan]

I get the following exception when clustering jboss portal on two nodes: I only extract first few lines of each exception here. Could someone please help me solve this? I suspected that it is a JBoss Cache configuration issue.

After some googling, i found the following:

https://jira.jboss.org/jira/browse/JBCACHE-955

http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4145333#4145333


Looks like it is a bug that is related to jboss cache, is it possible to switch to other caching library for jboss portal? Could someone please give me some advice?


And one more link suggesting that it is a bug with jboss cache

https://jira.jboss.org/jira/browse/JBPORTAL-1626
