Develop web service with jaxws - print request/response SOAP messages

1) add chain configuration file LogMessage_handler.xml under folder WEB-INF\classes


<?xml version="1.0" encoding="UTF-8"?>
<handler-chains xmlns="http://java.sun.com/xml/ns/javaee">
  <handler-chain>
    <handler>
      <handler-name>com.abc.ws.demows.skeleton.LogSoapMessageHandler</handler-name>
     <handler-class>com.abc.ws.demows.skeleton.LogSoapMessageHandler</handler-class>
    </handler>
  </handler-chain>
</handler-chains>


2) add above configured class LogSoapMessageHandler


package com.abc.ws.demows.skeleton;

import java.io.ByteArrayOutputStream;
import java.io.OutputStream;

import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.ws.LogicalMessage;
import javax.xml.ws.handler.LogicalHandler;
import javax.xml.ws.handler.LogicalMessageContext;
import javax.xml.ws.handler.MessageContext;

public class LogSoapMessageHandler implements
LogicalHandler<LogicalMessageContext> {

public void close(MessageContext msgCtx) {

}

public boolean handleFault(LogicalMessageContext lmc) {

return false;
}

public boolean handleMessage(LogicalMessageContext context) {
boolean direction = ((Boolean) context
.get(LogicalMessageContext.MESSAGE_OUTBOUND_PROPERTY))
.booleanValue();

try {
LogicalMessage lm = ((LogicalMessageContext) context).getMessage();
if (lm != null) {
Source source = lm.getPayload();
if (source != null) {
System.out
.println(direction == true ? "Response SOAP Message : \n"
+ getSourceAsString(source)
: "Request SOAP Message : \n"
+ getSourceAsString(source));

} else {
System.out.println(" No Message payload was present");
}
} else {
System.out.println("\n No Message was present");
}
} catch (Exception e) {
System.out.println("Exception while dumping soap message." + e);
}

return true;
}

private String getSourceAsString(Source s) throws Exception {

Transformer transformer = TransformerFactory.newInstance()
.newTransformer();

OutputStream out = new ByteArrayOutputStream();
StreamResult streamResult = new StreamResult();
streamResult.setOutputStream(out);
transformer.transform(s, streamResult);

return streamResult.getOutputStream().toString();
}

}

3) add above class to skeleton class

@WebService( endpointInterface = "com.abc.ws.demows.DemoService" )

@HandlerChain( file = "LogMessage_handler.xml" )

public class DemoServiceImpl implements DemoService {

...

}

4) test result

Request SOAP Message :

<?xml version="1.0" encoding="UTF-8"?><createReqParams xmlns="http://ws.abc.com/demows/" xmlns:S="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns2="http://ws.abc.com/common/"><header><ns2:clientId

>CID0001</ns2:clientId><ns2:timeStamp>2013-02-04T12:46:36.693+08:00</ns2:timeStamp></header><prodId>PID02</prodId></createReqParams>

request data: prodId=PID02,clientId=CID0001,timestamp=Mon Feb 04 12:46:36 SGT 2013

Response SOAP Message :

<?xml version="1.0" encoding="UTF-8"?><createRespParams xmlns="http://ws.abc.com/demows/" xmlns:ns2="http://ws.abc.com/common/"><header><ns2:returnCode>9999</ns2:returnCode><ns2:returnMessage>OK</ns2:

returnMessage></header><prodId>PID01</prodId><prodStatus>Pass</prodStatus></createRespParams>
