Problem accessing EJB's in KM Scheduler Task

Question

Hi,
I have created a new SchedulerTask which implements com.sapportals.wcm.service.scheduler.ISchedulerTask.
In the run method of the SchedulerTask, I was trying to access the Session bean as below
     try {
          Context initial = new InitialContext();
          Object objref = initial.lookup("JNDI Name Of the Session Bean");
          Object obj = PortableRemoteObject.narrow(objref, BeanHome.class);
     } catch (NamingException ex) {
          ex.printStackTrace();          
     } catch (Exception ex) {
          ex.printStackTrace();          
When the task is executed, initial lookup is returning 915(I have tried to log the objref above to console and it prints 915) which is resulting in classcast exception while narrowing.
But, When I placed the same code in a Portal Component, it works fine.
Portal component and SchedulerTask are in the same portal application project, which mean that all configurations are same.
I have been struggling very hard to figure out this indifferent behavior.
Any hints or help would be greatly appreciated.
Thanks and Regards,
Suresh.

Hi,
Try some thing like this:
ClassLoader originalContextClassLoader = Thread.currentThread().getContextClassLoader();                                   
try {
          Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
          Context initial = new InitialContext();
          Object objref = initial.lookup("JNDI Name Of the Session Bean");
          Object obj = PortableRemoteObject.narrow(objref, BeanHome.class);
     } catch (NamingException ex) {
          ex.printStackTrace();          
     } catch (Exception ex) {
          ex.printStackTrace();          
     finally {
     Thread.currentThread().setContextClassLoader(originalContextClassLoader);
