Hello, I have 2 linux servers running jboss 4.0.1 and using jboss-cache.jar 1.2.4. Session replication is working correctly ONLY first time, after both servers has been restarted. So the second time whenever i change the values of the session (i even tried to create a new one) they have not been replicated across .. In my test.jsp I am using this: request.getSession().setAttribute("test","test1") ; request.getSession().getAttribute("test") ; Here is configuration I am using: In web.xml : (both servers) <distributable/> In jboss-web.xml : (both servers) | <replication-config> <replication-trigger>SET_AND_NON_PRIMITIVE_GET</replication-trigger> | <replication-granularity>attribute</replication-granularity> | </replication-config> In tc5-cluster-service.xml <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | . | <attribute name="CacheMode">REPL_SYNC</attribute> | .. | <UDP mcast_addr="230.1.2.3" mcast_port="45577" bind_addr="192.168.1.1" | 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="192.168.1.2" is set for second server. In jbossweb-tomcat50.sar/META-INF/jboss-service.xml (both servers) <depends>jboss.cache:service=TomcatClusteringCache</depends> | <depends>jboss:service=TransactionManager</depends> Thanks in advance!
