Red Hat Training
A Red Hat training course is available for JBoss Enterprise Application Platform Common Criteria Certification
26.2.2. Deployment Via a -service.xml File
As in JBoss Enterprise Application Platform 4.x, you can also deploy a JBoss Cache instance as an MBean service via a
-service.xml
file. The primary difference from JBoss Enterprise Application Platform 4.x is the value of the code
attribute in the mbean
element. In JBoss Enterprise Application Platform 4.x, this was org.jboss.cache.TreeCache
; in JBoss Enterprise Application Platform 5.x it is org.jboss.cache.jmx.CacheJmxWrapper
. Here's an example:
<?xml version="1.0" encoding="UTF-8"?> <server> <mbean code="org.jboss.cache.jmx.CacfheJmxWrapper" name="foo:service=ExampleCacheJmxWrapper"> <attribute name="TransactionManagerLookupClass"> org.jboss.cache.transaction.JBossTransactionManagerLookup </attribute> <attribute name="MuxChannelFactory"><inject bean="JChannelFactory"/></attribute> <attribute name="MultiplexerStack">udp</attribute> <attribute name="ClusterName">Example-EntityCache</attribute> <attribute name="IsolationLevel">REPEATABLE_READ</attribute> <attribute name="CacheMode">REPL_SYNC</attribute> <attribute name="InitialStateRetrievalTimeout">15000</attribute> <attribute name="SyncReplTimeout">20000</attribute> <attribute name="LockAcquisitionTimeout">15000</attribute> <attribute name="ExposeManagementStatistics">true</attribute> </mbean> </server>
The
CacheJmxWrapper
is not the cache itself (i.e. you can't store stuff in it). Rather, as it's name implies, it's a wrapper around an org.jboss.cache.Cache
that handles integration with JMX. CacheJmxWrapper
exposes the org.jboss.cache.Cache
via its CacheJmxWrapperMBean
MBean interfaces Cache
attribute; services that need the cache can obtain a reference to it via that attribute.
