Hi Amila,
Sorry for the late response but I've been very busy last days trying to finish
my final project to get my degree.
Yes it is true that when there is a NPE the excepcion should be thrown as Axis2
fault. As you can see, in exception A, the message contains an Axis2 fault and
is well formed but the client seems to have a little confusion because when
client receives this one, it receives it as a Remote Exception instead of Axis2
fault.
If the client does e.getMessage(), the message printed is: "unknown".
If it does e.printStackTrace(), the message printed is:
org.apache.axis2.AxisFault: unknown

org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:486)

at client.Medici_LinkStub.validate (Medici_LinkStub.java:1044)
at client.ClientUtilities.validateTest(ClientUtilities.java:57)
at client.Client.main(Client.java:72)
What is strange to me is the getInboundFaultFromMessageContext(Utils.java:486).
As I said, the exception is well formed but besides of being an Axis2 fault,
the action is validateDataAccessException and I don't know if that is right.
In the case of exception B, it was thrown from the message receiver, not from
the skeleton, in the try {}catch inside invokeBusinessLogic method, inside the
following if statement:
if((op.getName()!=null) && ((methodName=
org.apache.axis2.util.JavaUtils.xmlNameToJava(op.getName.getLocalPart()))!=null))
I'm doing
if(sessionControl.getSystem==null)
buildValidationException("SYSTEM NOT VALIDATED. YOU MUST VALIDATE BEFORE
INVOKING A METHOD.");
that is the place where I sent exception B, and that is the case when the fault
action was sent wrongly. The buildValidationException method was this:
public static ValidationException buildValidationException(String _message,
Logger _logger){
if(_logger!=null)
_logger.error(_message);
ValidationException exception=new ValidationException("Validation
Fault");
ValidationFault fault=new ValidationFault();
fault.setDescription(_message);
exception.setFaultMessage (fault);
return exception;
}
Thanks,
Jorge Fernández

if there is a null pointer exception it is correct to throw the Axis2 fault.
I tried with the validation exception and it worked correctly. which operation
send the fault action wrongly?
can you send a sample skelton code?
