Axis generates unwanted xsi:nil elements

We're using axis to generate Java stubs from our WSDL, but when we generate a message and send it, it includes elements without values as <blahblah xsi:nil="true" /> which causes the server side to reject the request. The other strange issue is that these nil elements are even included in the request when it is a choice, that is all of the choice elements are returned, with the extra elements having xsi:nil

I have tries specifying <xsd:element ... nillable="false"> for some of the elements in the xsd description, but so far this has not had any effect.

We're running Axis 1.3, I've tried targetting 1.0 when generating the stubs (-T 1.0 running WSDL2Java) but had no effect either.

is the choice element, by your design, empty?

For the element with 'xsi:nil="true"' to be valid, I think you should put <xsd:element ... nillable="true">. Default is 'nillable="false"'.

We don't specify a 'nillable' attribute in the element, but we still get the xsi:nil in the message I found a thread stating that trying -W for the WSDL2Java command line has fixed this in the past, but not for us.

I should also mention that we control the server and the incorrect management of the 'nil' attribute is caused by the Castor deserialisation, but at this stage it will not be a simple operation to upgrade Castor or replace it with something more robust. The Castor deserialisation has been there a while and has some custom code added to it, although luckily it is cleanly layered should we need to cut it lose later.
Don't get me started about those stupid light bulbs.
