[jboss-user] [JBossCache] - NotClassDefFoundException when using JBoss Cache1.4GA within

Hi all, I'm using JBoss Cache1.4GA within Jboss AS 4.0.2, when the cache mode is LOCAL, it works well, but if I set the cache mode to REPL_SYNC(within two JBoss instances), an NotClassDefFoundException is thrown out when the replication should take place, the error message is: Caused by: java.lang.NoClassDefFoundError: org/jboss/cache/marshall/ObjectSerializationFactory$JBossObjectInputStreamOverride But actually org.jboss.cache.marshall.ObjectSerializationFactory$JBossObjectInputStreamOverride exists in jboss-cache.jar..... Following is the configuration: <mbean code="org.jboss.cache.TreeCache" name="jboss.cache:service=V360Cache"> | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | <attribute name="TransactionManagerLookupClass"> | org.jboss.cache.JBossTransactionManagerLookup | </attribute> | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | <attribute name="CacheMode">REPL_SYNC</attribute> | <attribute name="ClusterName">TreeCache-Cluster</attribute> | <attribute name="ClusterProperties"></attribute> | <attribute name="ClusterConfig"> | <config> | <UDP mcast_port="45577" ip_ttl="64" ip_mcast="true" | mcast_send_buf_size="150000" mcast_recv_buf_size="80000" | ucast_send_buf_size="150000" ucast_recv_buf_size="80000" | loopback="false" /> | <PING timeout="2000" num_initial_members="3" | up_thread="false" down_thread="false" /> | <MERGE2 min_interval="10000" max_interval="20000" /> | <FD shun="true" up_thread="true" down_thread="true" /> | <VERIFY_SUSPECT timeout="1500" up_thread="false" | down_thread="false" /> | <pbcast.NAKACK gc_lag="50" | retransmit_timeout="600,1200,2400,4800" up_thread="false" | down_thread="false" /> | <pbcast.STABLE desired_avg_gossip="20000" | up_thread="false" down_thread="false" /> | <UNICAST timeout="600,1200,2400" window_size="100" | min_threshold="10" down_thread="false" /> | <FRAG frag_size="8192" down_thread="false" | up_thread="false" /> | <pbcast.GMS join_timeout="5000" | join_retry_timeout="2000" shun="true" print_local_addr="true" /> | <pbcast.STATE_TRANSFER up_thread="false" | down_thread="false" /> | </config> | </attribute> | <attribute name="InitialStateRetrievalTimeout">20000</attribute> | <attribute name="SyncReplTimeout">15000</attribute> | <attribute name="LockAcquisitionTimeout">10000</attribute> | <attribute name="EvictionPolicyClass"></attribute> | </mbean> What's wrong with it? Did I miss any configuration items? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962758#...
