How to use ArrayList in Java Web Service

Hi frenz,

i am having a web service that is having 3 operations. They are all working fine.

now i want to add the forth operation with a return type of "ArrayList".

i tried, but it thrown an error:

error: Collection types are not supported in literal mode - Type: "java.util.ArrayList"

This is my wsdl file.
