Problem with Java Collections and Axis2

[pramodh somashekara]

Hi,
I'm using latest version of Axis2 - 1.4.1 and would like to know whether it supports Java Collection types like ArrayList,
HashMap and Maps etc. Currently i'm getting following exception and believe that even the WSDL generation through
Axis2 tool is not coming correct. I would appreciate for your response. thanks

Web services are platform- and language-independent, so you can't use Java Collections classes. Anything that can be expressed with an XML Schema (like an array) is fine.
