Hi all,
I'm having big problems in load balancing a web service. If I have just
one instance of my web service everything is fine, with two the
application which should use the web service is not able to connect to
the correct instance.
The problem seems to lie in Axis and the way cookies are handled
(http://nagoya.apache.org/jira/browse/AXIS-1080).
Since the web service need sessions, the instance ID and session ID are
stored in cookies. Axis seems to remember only the last cookie thus
making impossible to connect to the correct instance.
So, here comes my question:
- - - the bug has been patched but only for Axis 1.1, I've not found any
reference to Axis 1.0
- - - WebObjects comes with Axis 1.0 and if I use Axis 1.1 I get
exceptions (abstracts methods...) (tried it in Apple's Security Demo)
- - - Thus I must use Axis 1.0 but there seems to be no patch to it.
So: has anybody been able to use Load Balancing with session based web
services ? Has Apple ever tested this ? Is there way to use Axis 1.1.
with WO ?
Thanx in advance,
Regards from Italy,
F
