Order of SOAP Handler call in JAX-WS

[Nikita Dutt]

Hi All,

I am trying to understand how a JAX-WS protocol handler gets executed on the server side. Have written a code where i thought the


output would be

------------------------------------
In SOAPHandler SOAPHandlerOne method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler SOAPHandlerTwo method:handleMessage - direction = inbound
------------------------------------


but am getting the output as

------------------------------------
In SOAPHandler SOAPHandlerTwo method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler SOAPHandlerOne method:handleMessage - direction = inbound
------------------------------------


Please let me know what am i missing , if this is an expected behavior ? then why ?

Handlers Code


First Handler

import java.io.PrintStream;
import java.util.Set;

import javax.xml.namespace.QName;
import javax.xml.ws.handler.LogicalMessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;


public class SOAPHandlerOne extends BaseHandler<SOAPMessageContext> implements SOAPHandler<SOAPMessageContext> {
    
    private static PrintStream out = System.out;
	private static final String HANDLER_NAME = "SOAPHandlerOne";
     
    public SOAPHandlerOne(){
		super();
		super.setHandlerName(HANDLER_NAME);		
    }
    
    public boolean handleMessage(SOAPMessageContext smc) {
    	Boolean outboundProperty = (Boolean) smc.get(LogicalMessageContext.MESSAGE_OUTBOUND_PROPERTY);
    	out.println("------------------------------------");
    	if (outboundProperty.booleanValue()) {
			out.println(" In SOAPHandler " + HandlerName + " method:handleMessage - direction = outbound ");
	    } else {
        	out.println(" In SOAPHandler " + HandlerName + " method:handleMessage - direction = inbound ");
        }	
		out.println("------------------------------------");    	
        	return true;
    }

  
	public Set<QName> getHeaders() {
		return null;
	}
}

Second Handler

import java.io.PrintStream;
import java.util.Set;

import javax.xml.namespace.QName;
import javax.xml.ws.handler.LogicalMessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class SOAPHandlerTwo extends BaseHandler<SOAPMessageContext> implements SOAPHandler<SOAPMessageContext> {
    
    private static PrintStream out = System.out;
	private static final String HANDLER_NAME = "SOAPHandlerTwo";
     
    public SOAPHandlerTwo(){
		super();
		super.setHandlerName(HANDLER_NAME);		
    }
    
    public boolean handleMessage(SOAPMessageContext smc) {
    	Boolean outboundProperty = (Boolean) smc.get(LogicalMessageContext.MESSAGE_OUTBOUND_PROPERTY);
    	out.println("------------------------------------");
    	if (outboundProperty.booleanValue()) {
			out.println(" In SOAPHandler " + HandlerName + " method:handleMessage - direction = outbound ");
	    } else {
        	out.println(" In SOAPHandler " + HandlerName + " method:handleMessage - direction = inbound ");
        }	
		out.println("------------------------------------");    	
        	return true;
    }

  
	public Set<QName> getHeaders() {
		return null;
	}
}

The handler-chain.xml file

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<javaee:handler-chains xmlns:javaee="http://java.sun.com/xml/ns/javaee" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<javaee:handler-chain>
<javaee:handler>
<javaee:handler-class>com.company.jaxws.handler.cardservice.common.SOAPHandlerOne</javaee:handler-class>
</javaee:handler>
<javaee:handler>
<javaee:handler-class>com.company.jaxws.handler.cardservice.common.SOAPHandlerTwo</javaee:handler-class>
</javaee:handler>
</javaee:handler-chain>
</javaee:handler-chains>


Why is it calling SOAPHandlerTwo before SOAPHandlerOne ?


similary if i have LogicalHandler along with the SOAPHandlerOne the output is coming as

------------------------------------
In SOAPHandler SOAPHandlerTwo method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler SOAPHandlerOne method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler LogicalHandlerThree method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler LogicalHandlerTwo method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler LogicalHandlerOne method:handleMessage - direction = inbound
------------------------------------



and not as


------------------------------------
In SOAPHandler SOAPHandlerOne method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler SOAPHandlerTwo method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler LogicalHandlerOne method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler LogicalHandlerTwo method:handleMessage - direction = inbound
------------------------------------
------------------------------------
In SOAPHandler LogicalHandlerThree method:handleMessage - direction = inbound
------------------------------------
