RE: session in AddressBook sample

[Yakubovich, Alexey]

Ivan,

Thanks for explanation, it helps in understanding... I write you, not to
a user list, because don't want to disturb all... 
So I know now why session does not work for me: I don't know how to
invoke handler (SimpleSessionHandler or any) on client side.  Can you
advise that? I checked (with remote debugger) that handler got invoked
on server, but not on client in my case...  I expected that 

stub.setMaintainSession(true);

in test code would provide that, it does not.

Thanks for help.

Alexey

Subject: RE: session in AddressBook sample

I'm using it successfully in Axis 1.1 via request handlers and a custom
version SimpleSessionHandler. There, you will see that Message context
contains a list of ActiveSessions, and each section is in turn nothing
but a hash table with stuff that survives across invocations.

All my web service methods receive as parameter ID that allows the
handler to look up the correct session for any request (next I'd like to
hide them in the SOAP header). The constructor for my Axis service class
refers to the message context and gets the session. Once there, you use
that session object as you would in jsp (session.set/get).

Your wsdd seems correct.

Subject: session in AddressBook sample

Hi, Axis users!

That's the third mail on the same topic... Sorry to repeat again about
the same... No only AddressBook sample seems not working, but the whole
Axis session implementation (class
org.apache.axis.session.SimpleSession) also seems to be a joke.  Please,
answer anybody who managed to use session in Axis web services, if not
with explanation how, but at least with positive statement that it could
work!  After failure with original example I tried with
SimpleSessionHandler and with SimpleSession ... and with <parameter
name="scope" value="Session"/> 

Just on case I attached the deploy.wsdd and
AddressBookSOAPBindingImpl.java files.
