Hi Ben, Exception got fixed after anonymous wrote : <cache usage=""transactional"/> tag in one of the hibernate class was removed from hibernate mapping file . and after application was deploed in tomcat 5.0: Also please not that, if hibernate.cache.provider_class=net.sf.hibernate.cache.TreeCacheProvider is replaced with following(coherence caching), everything works without need to change mapping file. And I was able to see cache keys(coherence) on web console(weblogic): hibernate.cache.provider_class=net.sf.hibernate.cache.CoherenceCacheProvider
I am using hibernate 2.1.8 & JBossCache 1.2. Here are the files: treecache.xml(don't know whether this correct at all): <?xml version="1.0" encoding="UTF-8"?> | <server> | <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/><mbean code="org.jboss.cache.TreeCache" name="jboss.cache:service=TreeCache"> | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | <!-- <attribute name="TransactionManagerLookupClass">org.jboss.cache.DummyTransactionManagerLookup</attribute>--> | | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | <attribute name="ClusterName">TreeCache-Cluster</attribute> | <attribute name="CacheMode">REPL_SYNC</attribute> | <attribute name="SyncReplTimeout">10000</attribute> | <attribute name="LockAcquisitionTimeout">15000</attribute> | <attribute name="FetchStateOnStartup">true</attribute> | <attribute name="EvictionPolicyClass"> | org.jboss.cache.eviction.LRUPolicy | </attribute> | <attribute name="EvictionPolicyConfig"> | <config> | <attribute name="wakeUpIntervalSeconds">5</attribute> | | </config> | </attribute> | <attribute name="ClusterConfig"> | <config> | <UDP mcast_addr="224.10.10.10" mcast_port="45566" | 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" bind_addr="127.0.0.1"/> | <PING timeout="2000" num_initial_members="3" | up_thread="false" down_thread="false"/> | <MERGE2 min_interval="10000" max_interval="20000"/> | <FD_SOCK/> | <VERIFY_SUSPECT timeout="1500" | up_thread="false" down_thread="false"/> | <pbcast.NAKACK gc_lag="50" retransmit_timeout="600,1200,2400,4800" | max_xmit_size="8192" up_thread="false" down_thread="false"/> | <UNICAST timeout="600,1200,2400" window_size="100" min_threshold="10" | down_thread="false"/> | <pbcast.STABLE desired_avg_gossip="20000" | up_thread="false" 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="true" down_thread="true"/> | </config> | </attribute> | </mbean> | </server> | | jdbc.properties which is used to initialize hibernate configuration with spring: jdbc.driverClassName=org.hsqldb.jdbcDriver | jdbc.url=jdbc:hsqldb:hsql://localhost:1476 | jdbc.username=sa | jdbc.password= | hibernate.show_sql=true | hibernate.dialect=net.sf.hibernate.dialect.HSQLDialect | hibernate.cache.provider_class=net.sf.hibernate.cache.TreeCacheProvider | #hibernate.cache.provider_class=net.sf.hibernate.cache.CoherenceCacheProvider | hibernate.c3p0.minPoolSize=5 | hibernate.c3p0.maxPoolSize=20 | hibernate.c3p0.timeout=1800 | hibernate.c3p0.max_statement=50 | applicationContext.xml of spring: <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd";> | | <!-- | -
