Create a JAX-WS Handler for Logging

This is a quick post about how to create a JAX-WS Handler for a client... actually it's really the same for a provider as well. I show how to get at the body to print it out... of course I'd recommend you use a logging framework instead of System.out.print*... Enjoy...

Create a java class that implements SOAPHandler<SOAPMessageContext>…

Implement the appropriate method (usually handleMessage())…

Create an xml file to hold the handler configuration and make sure the <handler-class> has the fully qualified name of you new Handler class.

<?xml version="1.0" encoding="UTF-8"?>

<handler-chains xmlns="http://java.sun.com/xml/ns/javaee">

<handler-chain>

<handler>

<handler-class>com.nationwide.handler.LogHandler</handler-class>

</handler>

</handler-chain>

</handler-chains>

Save this handler config xml file at the same location as the Service class, that is the generated class that extends javax.xml.ws.Service.

Now update this service class to add the @javax.jws.HandlerChain annotation and set it’s “file” attribute equal to the name of your config file.
