<soapenv:Header>  
     <UsernameToken xmlns="http://siebel.com/webservices"&gt;username&lt;/UsernameToken&gt;

Answer 1

If you're already using spring in your application, then it makes sense to use Spring WebServices to access to the service.

The manual has a chapter on how to use Spring-WS from the client. The good news here is that Spring-WS has no requirement on the target service WSDL, in fact it actively discourages it. You can invoke the webservice using a variety of bindings, such as JAXB or raw DOM if you choose. The docs cover all the options.

Webservices in siebel are defined in SOAP form, siebel guys have sent you a SOAP message, ask to siebel guys for the wsdl file. They can get it from siebel client application inbound web services. Then you can use the spring framework suggested by skaffman, axis2. These frameworks provide you an abstraction in the form of classes to call the web services.
