Hi Deepal,

    I have added the code in the handler class like

	if(msgContext.getFLOW()==1)
        {
        	 logger.info("This is inFlow");
        	 System.out.println("This is inFlow");
        	 MessageContext faultContext =                                 
        		 MessageContextBuilder.createFaultMessageContext(msgContext, new 		
AxisFault("validation failed error", new QName("validation error", "wsa"))); 
        		 AxisEngine.sendFault(faultContext); 
        	        	 
  	}

  I am using the same handler class for inflow and outfault flow thats why i
am checking if(msgContext.getFLOW()==1). At client console i am getting
error like 

org.apache.axis2.AxisFault: validation failed error

	at java.lang.Thread.run(Thread.java:735)

and its keep on executing the handler, Because i am able to see the log
message i am printing in inflow if condition again and again. I am printing
the message context in OutFaultFlow. i am getting the message like 
			
This is OutFaultFlow
 messagecontext==<?xml version='1.0' encoding='utf-8'?><soapenv:Envelope
xmlns:s
oapenv="http://www.w3.org/2003/05/soap-envelope"><soapenv:Body><soapenv:Fault

Thanks,
Swapna Soni.
