Web Services with SAAJ - Java SOA - page 222

The getBook method accepts a string ISBN code and returns the topic object that matches it.
In this example, you want to invoke the service without creating portable wrapper objects on
the client with a tool like wsimport . So, you'll write a file that contains a complete SOAP
envelope, and then read that into a SAAJ Dispatch to invoke the service. Here is the SOAP
message in your client, isbnMsg.txt:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<i:isbn xmlns:i="http://ns.soacookbook.com/catalog">12345</i:isbn>
</soap:Body>
</soap:Envelope>
Note that the line breaks are optional; you will be able to invoke your service successfully
whether you include them or not. I included them here for readability.
So, now create a dispatch client. There are a few steps involved. The listing in Example 5-4
represents a complete example.
