4.5.2.3. Via JBoss Microcontainer (JBoss AS 5.x)

CacheJmxWrapper is a POJO, so the microcontainer has no problem creating one. The trick is getting it to register your bean in JMX. This can be done by specifying the org.jboss.aop.microcontainer.aspects.jmx.JMX annotation on the CacheJmxWrapper bean: 




<?xml version="1.0" encoding="UTF-8"?>



<deployment xmlns="urn:jboss:bean-deployer:2.0">



   <!-- First we create a Configuration object for the cache -->

   <bean name="ExampleCacheConfig"

         class="org.jboss.cache.config.Configuration">

      

      ... build up the Configuration

      

   </bean>

   

   <!-- Factory to build the Cache. -->

   <bean name="DefaultCacheFactory" class="org.jboss.cache.DefaultCacheFactory">      

      <constructor factoryClass="org.jboss.cache.DefaultCacheFactory" 

                   factoryMethod="getInstance"/>

   </bean>

   

   <!-- The cache itself -->

   <bean name="ExampleCache" class="org.jboss.cache.CacheImpl">

      

      <constructor factoryMethod="createnewInstance">

          <factory bean="DefaultCacheFactory"/>

          <parameter><inject bean="ExampleCacheConfig"/></parameter>

          <parameter>false</false>

      </constructor>

          

   </bean>

   

   <!-- JMX Management -->

   <bean name="ExampleCacheJmxWrapper" class="org.jboss.cache.jmx.CacheJmxWrapper">

      

      <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.cache:service=ExampleTreeCache", 

                         exposedInterface=org.jboss.cache.jmx.CacheJmxWrapperMBean.class, 

                         registerDirectly=true)</annotation>

      

      <constructor>

          <parameter><inject bean="ExampleCache"/></parameter>

      </constructor>

          

   </bean>



</deployment>      

As discussed in the Programatic Registration section, CacheJmxWrapper can do the work of building, creating and starting the Cache if it is provided with a Configuration . With the microcontainer, this is the preferred approach, as it saves the boilerplate XML needed to create the CacheFactory : 




<?xml version="1.0" encoding="UTF-8"?>



<deployment xmlns="urn:jboss:bean-deployer:2.0">



   <!-- First we create a Configuration object for the cache -->

   <bean name="ExampleCacheConfig"

         class="org.jboss.cache.config.Configuration">

      

      ... build up the Configuration

      

   </bean>

    

   <bean name="ExampleCache" class="org.jboss.cache.jmx.CacheJmxWrapper">

      

      <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.cache:service=ExampleTreeCache", 

                         exposedInterface=org.jboss.cache.jmx.CacheJmxWrapperMBean.class, 

                         registerDirectly=true)</annotation>

      

      <constructor>

          <parameter><inject bean="ExampleCacheConfig"/></parameter>

      </constructor>

          

   </bean>



</deployment>
