I have control on authentication web service but not on the webservice1(testWebservice). Its like this, the client has to be authenticated before accessing the testwebservice. Both of these reside in different servers. If a client gets the wsdl of testwebservice, asume using axis, how will it be possible to add header in the soap request? Will the wsdl of testwebservice give some information regarding the intermediate node? I am not clear about this point.
