Stateless Session Bean has no Context when called from WAR

Question

Hello,
Here is the code for my stateless session bean (it will carry out certain actions based on the timer service)
package DigestTest;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.util.Date;
import javax.ejb.*;
import javax.ejb.TimedObject;
import javax.ejb.Timer;
* This is the bean class for the MasterTimerBean enterprise bean.

public class MasterTimerBean implements SessionBean, MasterTimerRemoteBusiness, MasterTimerLocalBusiness, TimedObject
private SessionContext context;
public void setSessionContext(SessionContext aContext)
context = aContext;
* @see javax.ejb.SessionBean#ejbActivate()
public void ejbActivate()
* @see javax.ejb.SessionBean#ejbPassivate()
public void ejbPassivate()
* @see javax.ejb.SessionBean#ejbRemove()
public void ejbRemove()
// </editor-fold>
* See section 7.10.3 of the EJB 2.0 specification
* See section 7.11.3 of the EJB 2.1 specification
public void ejbCreate()
// TODO implement ejbCreate if necessary, acquire resources
// This method has access to the JNDI context so resource aquisition
// spanning all methods can be performed here such as home interfaces
// and data sources.
public void ejbTimeout(Timer timer)
try
BufferedWriter writer = new BufferedWriter(new FileWriter("C:\\timerTest.txt"));
writer.write("Timer has tripped");
writer.newLine();
writer.flush();
writer.close();
catch(Exception e)
return;
// Add business logic below. (Right-click in editor and choose
// "EJB Methods > Add Business Method" or "Web Service > Add Operation")
public String initializeTimer()
String result = "\n\nInitializing Timer\n";
try
// Create Your Timer
if(context!=null)
TimerService ts = context.getTimerService();
result = result+"Instantiating Timer Object\n";
Timer timer = ts.createTimer(new Date(), 5000, "TestTimer");
result = result+"About to grab TimerHandle";
TimerHandle timerHandle = timer.getHandle();
else
result = result+"\nContext Object is null\n";
catch (Exception e)
result = result+"\nError:\n"+e.toString();
return result;
public String writerTest()
String result = "about to write";
try
result = result+"\nOpening the file";
BufferedWriter writer = new BufferedWriter(new FileWriter("C:\\timerTest.txt"));
result = result+"\nWriter Test Passed";
writer.write("Writer Works");
writer.newLine();
result = result+"\nFlushing writer";
writer.flush();
result = result+"\nClosing writer";
writer.close();
catch (Exception e)
result = result+"\n"+e.toString();
return result;
I am calling initializeTimer() from a jsp page with a simple <jsp:useBean tag>.
The program keeps returning that the context variable is not set(this is from the context!=null conditional in initializeTimer()). I am very confused, I thought that setContext(...) was called by the container upon instantiation (and thus should happen completely without any action from me).
How am I able to call a session bean that has not had the context set?
Any information is appreciated,
Thanks,
Scott

thank you for your reply, rajeevm007.
it seems that the question is really a problem now.
i think i should update weblogic to the lastest version and confirm this question. if it still in there, it seems that we have to reset the global variables all manually. so, now, we are discussing that should we modify all the ejbs, or wait the next version of weblogic. :) of cause the second choice is a joke.
no other good choice?
maybe in the march of the next year....
cheers
thank you again.
