Weblogic database resources using JMX

Question

Does anyone have an idea on how to get user defined Datasource information from Weblogic server using JMX?
I have tried with different ObjectNames but none of them seems to work
ObjectName service = new ObjectName("com.bea:Name=EditService,Type=weblogic.management.mbeanservers.edit.EditServiceMBean");
and
connection.getAttribute(service, "JDBCSystemResources");
Thank you very much for your help.

I would encourage you to use WLST because it's much easier IMHO. What is your use case?
But if you must use java, this should get you started:
package foo;
import java.util.Hashtable;
import javax.management.MBeanAttributeInfo;
import javax.management.MBeanInfo;
import javax.management.MBeanServerConnection;
import javax.management.ObjectName;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;
public class TestJMX {
     public static void main(String[] args) throws Exception {
          JMXConnector jmxCon = null;
          try {
               JMXServiceURL serviceUrl = new JMXServiceURL(
                         "service:jmx:t3://localhost:7011/jndi/weblogic.management.mbeanservers.edit");
               System.out.println("Connecting to: " + serviceUrl);
               Hashtable env = new Hashtable();
               env.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
                         "weblogic.management.remote");
               env.put(javax.naming.Context.SECURITY_PRINCIPAL, "weblogic");
               env.put(javax.naming.Context.SECURITY_CREDENTIALS, "welcome1");
               jmxCon = JMXConnectorFactory.newJMXConnector(serviceUrl, env);
               jmxCon.connect();
               MBeanServerConnection con = jmxCon.getMBeanServerConnection();
//               Set<ObjectName> mbeans = con.queryNames(null, null);
//               for (ObjectName mbeanName : mbeans) {
//                    System.out.println(mbeanName);
               System.out.println("***** JDBC System Resources ********" );
               ObjectName domain = new ObjectName("com.bea:Name=medrec,Type=Domain");
               ObjectName[] objNames = (ObjectName[]) con.getAttribute(domain, "JDBCSystemResources");
               System.out.println("JDBCSystemResources");
               for( ObjectName objName : objNames )
                    System.out.println( objName );
                    MBeanInfo info = con.getMBeanInfo(objName);
                    MBeanAttributeInfo[] attributes = info.getAttributes();
                    for( MBeanAttributeInfo attrInfo : attributes )
                         String name = attrInfo.getName();
                         System.out.println( name + " " + attrInfo.getType() + " " + con.getAttribute(objName, name) );
          } finally {
               if (jmxCon != null)
                    jmxCon.close();
}For me that prints:
