Friends,
I'm using Pojo Cache first time. I'm getting ClassCastException: org.jboss.cache.pojo.impl.PojoCacheImpl cannot be cast to org.jboss.cache.pojo.PojoCache while I try to retrieve an instance of PojoCache using following code.

| MBeanServer server = MBeanServerLocator.locateJBoss();
ObjectName on = null;


try {
 on = new ObjectName("jboss.cache:service=PojoCache");
 } catch (MalformedObjectNameException e) {
 logger.error("The format of the string does not correspond to a valid ObjectName.", e);
 } catch (NullPointerException e) {
 logger.error("An application attempts to use null in a case where an object is required.", e);
 }
 

PojoCacheJmxWrapperMBean cacheWrapper = (PojoCacheJmxWrapperMBean) MBeanServerInvocationHandler.
newProxyInstance(server, on, PojoCacheJmxWrapperMBean.class,false);

 PojoCache pojoCache = cacheWrapper.getPojoCache(); |

Below is the cache configuration file I'm using. This file is copied to 'deploy' directory of 'default' server.


|| pojocache-jboss-beans.xml ||
| <?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="CacheConfiguration">
<!-- Externally injected services -->
<property name="runtimeConfig">

<property name="transactionManager">

</property>
</bean>

<property name="lockAcquisitionTimeout">15000</property>

</bean>
 
<bean name="PojoCacheJmxWrapper">
<annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.cache:service=PojoCache", exposedInterface=org.jboss.cache.pojo.jmx.PojoCacheJmxWrapperMBean.class, registerDirectly=true)</annotation>
<property name="configuration">
<inject bean="CacheConfiguration" />
</property>
</bean>
 
</deployment> |

Please help to resolve this.

Thank you.
