Re: Session

Hi Stefano,
   
        If you remember, we stumbled upon the same problem on how to send sessions using headers from axis to .net client and back.  As I was dealing with one service maintaining sessions was  a snap with the technique of sending headers. Now, I would like to know if there is a way  to persist this information across multiple services.

Ex-  One service has a method login, which upon sucessfull auth initiates a session mgmt process by including the headers, client makes another call on a different service for some other functionality.  Client can  include the sessionID which he got from login method in the request header which he sends for the new request, If I retrieve the sessionID from the second method invocation? How would I verify that the session ID that I got is indeed a valid session and the caller has gone through the auth process before invoking it.  

    Thank you for all your time and help

Sorry for my late reply.
Here is what I added to my wsdl to manage session:

1)    Add this namespace declaration in root element of wsdl file (in
<wsdl:definitions>):

xmlns:session=http://xml.apache.org/axis/session

2)    Add this schema definition to <wsdl:types>:

<schema targetNamespace="http://xml.apache.org/axis/session"
xmlns="http://www.w3.org/2001/XMLSchema">
<simpleType name="session">
<restriction base="xsd:long"/></simpleType>
<element name="sessionID" type="session:session"/></schema>


3)    Add this wsdl message:

<wsdl:message name="soapHeader">
<wsdl:part name="sessionID" element="session:sessionID"/></wsdl:message>

4)    In wsdl bindings, add this soap header declaration, both in
<wsdl:input> and <wsdl:output> of your operation:

<wsdlsoap:header message="impl:soapHeader" part="sessionID" use="literal"/>


As you can see, my Axis web service is doc/lit style.
I hope this can be useful for you, I'd like to know if it works.
Stefano

Hello Stefano,

can u please explain me how you add the header in your wsdl?
Some tool or by hand?

Can you show me your wsdl for example?

And how can .Net use this header to make things work?

Thanks Tomi

I didn't use cookies, but only a soap header with SimpleSessionHandler on
Axis side.
I also added an header in my wsdl, so .NET implements it automatically.

I did not post any troubles as the need tapered off.  But, I read in the
article:  To do this from a client that uses the axis runtime, the client
has to call the setMaintainSession method of the
org.apache.axis.client.Service interface. This interface is implemented by
the Locator class generated by the WSDL2Java generation tool. Once you
    
call
  
the method, the Axis framework will automatically return the cookie to the
server:

The problem i ran in to was how to make the client make and send the
cookie.  How did you do it in .NET if I may ask.  The path I took, which
was not successful for me, was to add a header with the session id in the
header.

Thanks.

Hi,
I used sessions between an Axis web service and a .NET client.
I didn't read your past messages, so I don't know what is your problem.

I am curious to know if anyone has implemented sessions without using
      
the
  
axis client.  It must be possible to interop w/ non java clients and use
sessions, but it has eluded me, so far.

You can mantain sessions between the client and server ... take a look
      
at
  
how
org.apache.axis.handlers.SimpleSessionHandler works ...
here's an article describing sessions.

 hi all

 I need to implement the following case, need some help in what way that
 can be done.

 I want to check if the same client is firing the request or a different
 client for a given web service.

 if it is the same client how to identify it?

 I want to keep most of the implementation on the server side.

 Thanks
