((org.apache.axis.client.Stub)stub).setProperty(org.apache.axis.client.Stub.SESSION_MAINTAIN_PROPERTY, Boolean.TRUE)
If you look at the code that you edited in the stub you should find the bit checking this property and setting MaintainSession on the call.
The session is per-stub, thus you can't share session across multiple instances of a stub, nor can you share session across multiple stubs generated from different WSDL. At least, not without major hacking.

Hi Thomas,
I am first working on the Cookie-based session maintainance. I could get it to work with the .NET client and a Java Web Service. But I have problem to get the Java client and the .NET Web Service to work. I ran the WSDL2Java to get the stubs and tried to modify the code in the stub. My simple .NET web service has a setNumber and a getNumber as web methods. The modification I did to the stub is to use a single "Call" object reference to both the set and get web methods and did a call.setMaintainSession(true), when I am calling the set method and used the same call for get. Interestingly the SOAP request for the get method is using the same session id which was set during the SOAP response of the set method, but my value is displayed as "0" irrespective of what number I set. Could you give me some hints as to why it is doing like this. If the above method is incorrect, could you kindly suggest a better one.

I will need to get back to the code that I have to make it work with the latest Axis version, but here is the modification that I did to the SimpleSessionHandler.java to wrapped the session id into a type. I recall (it was a while ago), that this is all I had to do (beside adding it to the Axis handler chain of course), to have it handled completely transparently in the code generated by VS Studio .NET C# when importing my web service reference. Actually there was something else to do: customize the service WSDL to contain the right SOAP header definition.
You can find enclosed the modified (and renamed) SimpleSessionHandler and the WSDL to give you and idea of what I did.
Sorry I can not give more details than that as I did that some times ago.

Hello Thomas,
I have a very similar problem that I am currently working with. I am wondering if you have the code for the following solution that you suggested and if you can share the same.

With cookies, the session id is sent between the client and the server in the HTTP headers, meaning that it is bound to the transport protocol. Change the protocol (for example, use JMS) and it does not work anymore.
If you look at the SOAP specification (from w3c.org), a SOAP message is composed of a SOAP body (the content of the message) but also of SOAP Headers which can be used for session management (for example) in a transport independent way. In simple term, what you put in the http header when using cookies, you now put it in the SOAP header.
Yes, it means a little more programming on your side as SOAP tools (client and server) do not necessarily handle SOAP headers in a complete transparent manner but it might be worth paying the cost if you are considering using other transport that just HTTP.
Take a look at org/apache/axis/handlers/SimpleSessionHandler.java which is a very good start to do SOAP header based session handling (for simple session handling, it can be used as is). The last time I played with that I had to slightly modify it to wrap the sessionID into a complex type so a C# .NET client can handle it in a complete transparent manner.

Hi Thomas,
I read the mailing list and found your reply to "Stateful Web Services" stating that the SOAP header solution to maintaining state would be the right approach rather than the Cookie-based approach. I could maintain session and application scope using the HTTP cookies set on the client side and session/application scope on the server side. Could you kindly explain in detail the Header-based approach?

If you are using Axis for your web service, setting the scope to session will turn cookie handling on from the server side point of view (Axis will use the HTTPSession features of the servlet container). On the C# client side, you have to create the cookie container for your service object to turn cookie on as well, and that is it, no need for anything else.
If you do a couple of searches in the mailing list archive you will find more details on all that for sure.

Hi,
I have a question regarding maintaining session. How do we maintain session for a Java Web Service which is consumed by a C# client? Any links would be appreciated.
