Session handling
Hi all,
Could someone plz. explain me the diff between session management using
cookies and SOAP headers? What is the default in Axis?
I have the following problem:
I am talking to a Axis based web service from inside a Jetspeed portlet
(for our purpose, we can assume it's a servlet). Different users access
the servlet from various machines, and the servlet container maintains
their sessions. Now I want to maintain sessions between the servlet
container machine and the web service. I am using
stub.setMaintainSession(true), but it's not doing the trick.
The reason is service requests from different users come from the same
machine (the servlet container machine), so that the web service thinks
that it's the same session, even if I am using different stubs for
different users.
Does SOAP header based session management solve this problem? If yes, how
do I switch to it from Cookie-based?
Thanks in advance
Sandeep

The session is maintain per stub. Since you create a new stub every time
(rather than use the previous stub), so you don't have the session behavior.
Since the user browser maintain cookies to the HTTPSession, you should
store the stub into the HTTPSession variable.

Hi Sandeep, Ricky:
The stubs end up caching the HTTP information (i.e. the HTTPTransport object)
per-Service (i.e. org.apache.axis.client.Service). This means that if you use
the same Locator object to get stubs, they'll all end up sharing the same
session. If you instead new up a fresh Locator for each client you want to
differentiate, you should get the right behavior.
Hope this helps,

Hi Ricky,
Thanx for your response.
I don't know whether I am doing it right, but I create a new
serviceLocator instance for each user, and get the stub from there.
Does that guarantee that the stub is different each time?
Also, I am not putting the stub manually in HttpSession. Why should I be
needed to do that?
thanx
Sandeep

You are using different stub for different user. Do you put the each stub
in the HttpSession ? How do you get a particular stub ?
