Question

So I need to consume a Web Service that uses a custom SoapHeader, as described below. What is the simplest way to pass the correct values through this header using Java. I’m using Netbeans.

<?xml version='1.0' encoding='utf-8'?\> <soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>   <soap:Header>     <CustomSoapHeader xmlns='http://snip'>       <UserName>'string'</UserName>       <Password>'string'</Password>     </CustomSoapHeader>   </soap:Header>   <soap:Body>     <SomeWebMethod xmlns='http://snip' />   </soap:Body> </soap:Envelope> 

EDIT: What’s the best way to display XML on Stack Overflow?

It might help to add that the Web Service is implemented in .NET and I cannot change the server side code.

Answer 1

Here are the basic steps, assuming you’re doing this on the client side:

• Install a HandlerResolver on your service interface (service.setHandlerResolver())
• Override HandlerResolver.getHandlerChain() to insert your own implementation of SOAPHandler
• Implement SOAPHandler.handleMessage() to modify the SOAP header before it’s sent out

You can pass parameters to your handler through the request context:

Map<String, Object> context = ((BindingProvider) port).getRequestContext(); context.put('userName', 'foo'); ... 

in handleMessage() you can get at the header like this:

public boolean handleMessage(SOAPMessageContext context) {     ...      SOAPMessage msg = context.getMessage();     msg.getSoapHeader();     ...  } 

Hope that helps. I’m guessing there’s also a way to do this stuff with annotations as well.
