Subject RE: [axis 2]Questions on the development process using Axis 2.0
Date Sat, 16 Jul 2005 04:06:45 GMT
Thank you for your feedback. We came through this issue and at that time
what we thought was to get the client side and serverside connection based
on WS policy. We don't have a policy implementation for axis2 right now. A
group of undergrads are doing some work on this right now. We have to differ
this until such time a policy implementation becomes available.

Regards,
Chathura
