    Beanshell - MBean issues

    Frank Henry Novice

      I was just starting to realize the pure coolness of using Beanshell in JBoss when I stumbled over this issue.

      I am having some wierd issues with a Beanshell script that is accessing an MBean and trying to call the MBean's methods.

      I have written an MBean that works fine and is accessible from the jmx-console and the methods can be executed there.

      All methods I want to access are in the interface and I can actually list them in the Beanshell script using reflection.

      I just cannot call some of them.

      I presume it might be that Beanshell is interpretating get/set/is as my attempt to access one of it's Attributes.

      Any one have any ideas?

      import javax.management.*;
      import org.jboss.system.server.*;
      import com.me.ManagerMBean;
      import java.lang.reflect.Method;
      
      try
      {
       MBeanServer mbs = MBeanServerFactory.findMBeanServer(null).get(0);
      
       print ( "MBeanServer : " + mbs );
      
       if (mbs == null )
       {
       return;
       }
      
       ObjectName objectName = new ObjectName("com.me:service=Manager");
      
       ManagerMBean rdm = (ManagerMBean)(MBeanServerInvocationHandler.newProxyInstance(mbs, objectName, ManagerMBean.class, false));
       print ("ManagerMBean : " + rdm);
      
       try
       {
       print ("auto : " + rdm.isAutoupdate() );
      
       }catch ( Throwable t )
       {
       print (t.getCause());
       t.printStackTrace();
       }
      
      }
      catch (Exception e )
      {
       System.out.println("Exception @ Test.MyTask.run() : " + e);
      }
