Binding SOAP header with the actual data which is passed in the webservice method which is called

Question

I need to post jobs in monster.com by using their web service. I have genarated the client files using wsimport. I am calling updateJob method which accepts <Job> type object. The client files have dedicated classes for SOAP headers, in which I am setting the required username and password. But I have no idea how do bind this Header object in my request, as the method I am calling only accepts <job> type objects.

The dedicated objects which constitute soap headers are being populated as follows

    MonsterHeader monsterHeader=new MonsterHeader();
    MessageDataType MessageDataType=new MessageDataType();
    MessageDataType.setMessageId("Company Jobs created on 06/09/2004 02:41:44 PM");
    MessageDataType.setTimestamp("2004-06-09T14:41:44Z");
    monsterHeader.setMessageData(MessageDataType);

    Security security=new Security();
    UsernameTokenType UsernameTokenType=new UsernameTokenType();
    UsernameTokenType.setUsername("testxftp");
    PasswordType PasswordType=new PasswordType();
    PasswordType.setValue("ftp12345");
    UsernameTokenType.setPassword(PasswordType);

The method which is being called is businessGatewayInterface.updateJob(job);

Also , please advise on some easy way to view my outgoing SOAP request.
