ClasscastException: Cannot Cast org.jboss.ha.framework.server.HAPartitionImpl cannot be cast to org.jboss.ha.framework.server.HAPartitionImpl

[djain101]

Hi,

I have setup a cluster partition in Jboss and trying to retrieve HAPartition object from ClusterPartition mbean. Below is my code:

ArrayList<MBeanServer> list = MBeanServerFactory.findMBeanServer(null);

for (MBeanServer server : list)
        {
            String onStr = "jboss:service=DefaultPartition";
            ObjectName objectName = new ObjectName(onStr);
           
            Set mbeans = server.queryMBeans(objectName, null);

            Object partitionObj = server.invoke(theName, "getHAPartition", null, null);
            org.jboss.ha.framework.server.HAPartitionImpl partition = (org.jboss.ha.framework.server.HAPartitionImpl) partitionObj;  //this line throwing ClassCastException
        }

The last line in above code is throwing ClasscastException: Cannot Cast org.jboss.ha.framework.server.HAPartitionImpl cannot be cast to org.jboss.ha.framework.server.HAPartitionImpl

I have same version of jbossha.jar in jboss lib and war's web-inf/lib folder. I am not sure why it is throwing classcast exception. Any help is much appreciated.

Thanks in advance !!!

Dharmveer

To answer your question, don't put a copy of jbossha.jar in WEB-INF/lib.
The one in the lib folder is already visible to your application.
