Hi;
ADB has some limitations like not being able to adapt itself for the changing
services. I mean that is suitable for the contract first approach. If your
service provider make some changes on the wsdl. As an example add some more
outpur parameters or changed the order of response elements. ADB fails. (There
were lots of threads in this mail group complaining about the Unexpected
subelement exceptions)
On the other hand if your service provider finalized its service than it is
simple to use. I 'm using it for integrating a very very core point like
customer module of an finance project with Axis2. 1.4.1 ADB and I had no
problem upto now.
Yours.

Subject: Re: Limitations in using ADB for our ws-clent
Sudhir,
Sorry, no progress from my end.
Currently I just have the WSDL and we are building our sw-client
against that. Unfortunately we will not have an opportunity to test
against the server until later, so we will not discover if ADB has a
limitation until we have chewed up a lot of time.
I am really happy with ADB - I think I have wrapped my head around
it's main ideas - but there is still that lingering concern to
discover if it will work. As I mentioned earlier in the thread we do
have several instances of "restriction" in our WDSL - ubt it looks to
be at the simple end of the spectrum.
If anyone has any "feel" for ADB's limitations we would really
appreciate guidance.
Cheers,
-Damian
