Srinath Perera resolved AXIS2-2796.
-----------------------------------

    Resolution: Fixed

This was not a Code gen bug. problem was soap action was set as incoming action at client side instead of outgoing action. I Placed a check set values differently for client and server and that seem to fix it.

> I have a complex type in WSDL with attribute marked as use="optional". I am using ADB serialization, "contract-first" - I generate Java from WSDL using WSDL2Java. When I do not set this attribute explicitly in my service (its value is null), I am getting NullPointerException. When this attribute is populated, everything works ok
> I am porting my app from Axis2 1.1.1 to 1.2. I have re-generated all my Java "stubs" using WSDL2Java 1.2. Apart of that, no code changes were done. Same code/WSDL works fine with 1.1.1
