Completed: At revision: 1055305 in branches\2.1 (i.e. 2.1.8-SNAPSHOT).
o Exception is due to a different thread context classloader at play when the
method is invoked through RMI as opposed to invocation through admin console.
Fixed by changing the context classloader for the lookups.
ClassCastException while starting snapshot (Stat Query) in G 215 Monitoring
portlet through java client

Key: GERONIMO-5355
URL: https://issues.apache.org/jira/browse/GERONIMO-5355
Project: Geronimo
Issue Type: Bug
Security Level: public(Regular issues)
Components: monitoring
Affects Versions: 2.1.5
Reporter: Amit Puri
Assignee: Vamsavardhana Reddy
Fix For: 2.1.8
In a java client where MBeanServerConnection is created and invoke
startSnapshot method in Monitoring Portlet of G 215, Stat Query snapshot
started but we can also find ClassCastException.
...
ERROR [MasterRemoteControlJMX]
org.tranql.connector.jdbc.TranqlDataSource$SelfReference incompatible with
javax.sql.DataSource
java.lang.ClassCastException:

In G 214, this exception does not come while using same java client.
These steps are followed in java client:
1.Creating MBeanServerConnection object
...
MBeanServerConnection mbServerConn;
JMXServiceURL serviceURL = new
JMXServiceURL(service:jmx:rmi:///jndi/rmi://localhost/JMXConnector);
HashtableString, Object env = new HashtableString, Object();
String[] credentials = new String[2];
credentials[0] = system;
credentials[1] = manager;
env.put(JMXConnector.CREDENTIALS, credentials);
JMXConnector connector = JMXConnectorFactory.connect(serviceURL, env);
mbServerConn = connector.getMBeanServerConnection();
..
2. Retrieving the mbean name to the agent-car-jmx plugin
..
if(PATH == null) {
SetObjectName mbeanNames = mbServerConn.queryNames(new
ObjectName(*:name=MasterRemoteControlJMX,*), null);
for(IteratorObjectName it = mbeanNames.iterator(); it.hasNext(); ) {
String mbeanName = ((ObjectName)it.next()).getCanonicalName();
if(mbeanName.contains(agent-car-jmx)
mbeanName.contains(MasterRemoteControlJMX) mbeanName.contains(GBean)) {
PATH = mbeanName;
break;
}}
if(PATH == null) {
throw new Exception([ERROR] Required mbean not found: agent-car-jmx);
}}
..
Here I am getting mbean name as
geronimo:J2EEServer=geronimo,ServiceModule=org.apache.geronimo.plugins.monitoring/agent-car-jmx/2.1.5/car,j2eeType=GBean,name=MasterRemoteControlJMX
3. Invoking startSnapshot
..
long time = 30;
int days = 2;
mbServerConn.invoke(new ObjectName(PATH),startSnapshot, new Object[] {
time, days }, new String[] { java.lang.Long, java.lang.Integer });
..

The exception seems to be due to a
org.tranql.connector.jdbc.TranqlDataSource$SelfReference object getting bound
to the JNDI instead of org.tranql.connector.jdbc.TranqlDataSource. The
TranqlDataSource object is to be obtained by calling getContent() method on the
SelfReference object.
