Hi Stefan, I am pasting a wsdl for your reference. Please see the embedded comments.
On the client side, C# needs to see the SessionID element in WSDL so that it can create member variable SessionID for the service. But Axis does not generate such a WSDL. Hence you need to modify the WSDL produced by Axis and manually add the SessionID element. Then you should use the modified WSDL in Visual Studio. Following is an example of the modified WSDL with the comments preceding the modifications. After you show this WSDL to Visual Studio, it will generate the proxy and you can retreive the Session ID by using authenticationService.SessionID. Hope this helps.

This is a modified version of the SessionHandler supplied with Axis which can be used. Also, you need to manually put the SOAP Header in the WSDL generated by Axis so that Visual Studio can generate the code for session variables.

We are trying to communciate from a .NET C# client. Can any one let me know, how to track sessions in this scenario? Basically, we would like to put some authorization info in a session object as the first call from the client will be for authentication. After that client will call other Axis (web) services for executing some more tasks. We would like to check for the authorization information for subsequent calls from the same client and deny services if we dont find the relevant information in the session object . Any help or pointers to solve this? Thank you all for your help and time. srini -- Srinivas Vemula +91 40 23547826- Ext 201 Associate Consultant +91 40 23541447 (Fax) Mensamind +91 98497-42720 (Mobile) Hyderabad India http://www.mensamind.com DISCLAIMER The information contained in this e-mail is confidential and intended for the named recipient(s) only.
