why Exception block is calling instead of EJBException block
i am calling one method from controller to ejb.in the EJB addEmployee if flag is true i am throwing exception saying that "match not found" and intrun it will call EJB catch block and then it should call controller EJBException block but it is calling Exception block;why it so??
controller
********
public void addEmployee()
{
try
{
remote.addEmployee();
}
catch(EJBException e)
{
System.out.println("match not found");
}
catch(Exception e)
{
}
}
EJB
*****
public void addEmployee() thows EJBException
{
try
{
//SOME BUSINESS PRCOESS;
if(flag)
throw new EJBException("match not found")
}
catch(EJBException e)
{
throw new EJBException("match not found")
}
catch(Exception e)
{
}
}
controller
********
public void addEmployee()
{
try
{
remote.addEmployee();
}
catch(EJBException e)
{
System.out.println("match not found");
}
catch(Exception e)
{
}
}
EJB
*****
public void addEmployee() thows EJBException
{
try
{
//SOME BUSINESS PRCOESS;
if(flag)
throw new EJBException("match not found")
}
catch(EJBException e)
{
throw new EJBException("match not found")
}
catch(Exception e)
{
}
}

Probably because the exception you throw is not a EJBException or a subclass of it.
ASKER
in EJB it is calling throw new EJBException("match not found") but in controller it is not calling EJBException block..
ASKER
tell me one thing can i write like this
if(flag)
throw new EJBException("match not found")
if(flag)
throw new EJBException("match not found")
> tell me one thing can i write like this
you can
Check the type of the exception. If you're calling a remote object then its probably getting wrapped in something like a RemoteException

this is remote method.
public java.util.Hashtable addEmployee(Employe emp) throws RemoteException;
so how can i avoid this??
ASKER
so now i watn to throw EJBException in the method so now i changed method to
public java.util.Hashtable addEmployee(Employe emp) throws RemoteException,EJBExcepti
public java.util.Hashtable addEmployee(Employe emp) throws RemoteException,EJBExcepti

sorry it retruns void ;;

catch the RemoteException means i should use the getCause() method in catch(Exception e) block;;
ASKER
if i write my own userdefined exception also same thing is happening
catch(RemoteException e)
{
Throable cause = e.getCause();
}
{
Throable cause = e.getCause();
}
Any kinds of exceptions thrown remotely will be wrapped up into remote exceptions and thrown by the container, I guess.
ASKER
if i write my own checked exception then its working fine;;

What's the difference b/w these two?

in my first post i have made a mistake now its working fine;
Java
Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
