Problem in Accessing the Siebel Web Service


I have a seibel web service which needs to be called from a SAP Webdynpro application. The URL is something like this.

I am using Adaptive Webservice model and without hardcoding this value i should be able to send the user name and password information to the webservice.

How i can achieve that. I am getting the error that,

<b>returned http code 500 (Internal Server Error) with unacceptable content type (text/html;charset=UTF-8).


<body>The server you are trying to access is either busy or experiencing difficulties. Please close the Web browser, open a new browser window, and try logging in again.[12:02:58]</b>

Siebel team was asked us to send the user/password info through SOAP header.

<b>Is there any way to set thatbusername/password info in NWDS (Basically set the SOAP Header) and if it is OK only if we can set it in the Webservices security in the Visual Administrator.</b>

Appreciate your reply.

Thanks and Regards,
