Hi,

When i start my applicaion, the jboss throws an exception as below, but this exception is occured occasionally, i read http://docs.jboss.org/jbportal/v2.6.4/referenceGuide/html/wsrp.html#consumer_configuration documents and i reconfigure the wsrp producer and consumer, but it happens again. This error is the same with this one http://community.jboss.org/message/426224#426224, but in this thread member mentioned that "the simplest is to delete portal-wsrp.sar" is this the only way to fix this problem. I try this fix but i met this problem again. What should i do? This issue is a configuration problem or what? Thank you for your interest.

Best Regards
