PojoCache Setup
thanvi Jan 17, 2007 12:57 AMHi
I new to Jboss as well as Jboss Cache. I am trying to set the JBossCache (PojoCache) in Jboss AS which has Jboss Portal.
Following are the steps.
Added the following pojocache-service.xml under deploy directory.
<?xml version="1.0" encoding="UTF-8"?> <!-- ===================================================================== --> <!-- --> <!-- Sample PojoCache Service Configuration --> <!-- --> <!-- ===================================================================== --> <server> <!-- Used inside JBoss AS --> <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/> <!-- ==================================================================== --> <!-- Defines configuration --> <!-- ==================================================================== --> <mbean code="org.jboss.cache.aop.PojoCache" name="jboss.cache:service=testPojoCache"> <!-- Used inside JBoss AS --> <depends>jboss:service=Naming</depends> <depends>jboss:service=TransactionManager</depends> <!-- Configure the TransactionManager --> <attribute name="TransactionManagerLookupClass">org.jboss.cache.DummyTransactionManagerLookup</attribute> <!-- Node locking scheme: OPTIMISTIC PESSIMISTIC (default) --> <attribute name="NodeLockingScheme">PESSIMISTIC</attribute> <!-- Note that this attribute is IGNORED if your NodeLockingScheme above is OPTIMISTIC. Isolation level : SERIALIZABLE REPEATABLE_READ (default) READ_COMMITTED READ_UNCOMMITTED NONE --> <attribute name="IsolationLevel">REPEATABLE_READ</attribute> <!-- Valid modes are LOCAL REPL_ASYNC REPL_SYNC INVALIDATION_ASYNC INVALIDATION_SYNC --> <attribute name="CacheMode">REPL_SYNC</attribute> <!-- Name of cluster. Needs to be the same for all clusters, in order to find each other --> <attribute name="ClusterName">Sample-Cluster</attribute> <!-- JGroups protocol stack properties. Can also be a URL, e.g. file:/home/bela/default.xml <attribute name="ClusterProperties"></attribute> --> <attribute name="ClusterConfig"> <config> <!-- UDP: if you have a multihomed machine, set the bind_addr attribute to the appropriate NIC IP address --> <!-- UDP: On Windows machines, because of the media sense feature being broken with multicast (even after disabling media sense) set the loopback attribute to true --> <UDP mcast_addr="228.1.2.5" 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> <!-- The max amount of time (in milliseconds) we wait until the initial state (ie. the contents of the cache) are retrieved from existing members in a clustered environment --> <attribute name="InitialStateRetrievalTimeout">20000</attribute> <!-- Number of milliseconds to wait until all responses for a synchronous call have been received. --> <attribute name="SyncReplTimeout">15000</attribute> <!-- Max number of milliseconds to wait for a lock acquisition --> <attribute name="LockAcquisitionTimeout">10000</attribute> <!-- <attribute name="EvictionPolicyClass"></attribute> --> <!-- Name of the eviction policy class.

Then I have added the jboss-aop.xml under the XXX.war/WEB-INF/ folder
<?xml version="1.0" encoding="UTF-8"?> <aop> <!-- This is JBossAop way of declaring every field in Address has a hook for both get and set. --> <prepare expr="field(* $instanceof{org.jboss.cache.aop.test.Person}->*)" /> </aop>
I am using the following test.jsp to test the same.
MBeanServer server=MBeanServerLocator.locateJBoss(); TreeCacheMBean cache; cache=(TreeCacheMBean)MBeanProxyExt.create(TreeCacheMBean.class, "jboss.cache:service=testPojoCache", server); cache.put("cache.test","1","4"); String output1 = (String) cache.get("cache.test","1"); out.println("</br>cache.test = " + output1); Person per= new Person(); cache.put("cahce.test","Person",per); output2 = (String) cache.get("cache.mvn","Person"); out.println("</br>cache.mvn= " + output2);
This works fine, but anychanges to the person object are not getting update in the cache.
I think adding the jboss-aop.xml under the WEB-INF folder alone doesnt solve the issue. What else has to be done?
Please Help.
