NoClassDefFoundError: org/jgroups/MembershipListener then trying to use JBossCache ---------------------------------------------------------------------------------- Key: JBAS-5397 URL: http://jira.jboss.com/jira/browse/JBAS-5397 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: JBossAS-4.2.2.GA Environment: Java 1.6, Ubuntu Linux 7.10, JBoss 4.2.2.GA default server. Reporter: Alexey Kakunin Trying to reduce size of war-file, I removed hibernate from it - to use hibernate, "build-in" into JBossAS. To be able to use it - I configured my hibernate properties to use JBossCache as cache provider: hibernate.cache.provider_class=org.hibernate.cache.OptimisticTreeCacheProvider But then I deployed my application - I received error: java.lang.NoClassDefFoundError: org/jgroups/MembershipListener caused during OptimisticTreeCacheProvider initialization. My war is not included neiver hibernate, nor jbosscache or jgroup. But since jboss-cache inclided into Jboss lib, I suppose jgroups also should be included there - othervise it is not possible to use it as second-level cache for hibernate. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
