Re: problems retrieving the value of ArrayList of Object Array
Hi,
For the below mentioned problem I tried using Axis 1.2 Beta and guess
what it works perfectly fine. All my values are retrieved properly from
the client stubs. I also found out that I don't have to write my custom
serializers for java.util.ArrayList. It is handled by axis itself. Was
this something that was handled in 1.2 Beta or in was it handled in 1.1
itself.
Thanks once again.
