Re: [nm-wg] Schema to Source Code Generators

[Paul D Mealor <pdm@hep.ucl.ac.uk>]

Hi,

Have you tried the Axis utilities? WSDL2Java may generate reasonable code 
for you. I had tried to use it on the last set of WXS schemas but it 
didn't like the SubstitutionGroups but is fine otherwise so I gave up. 
However, Trang doesn't generate substitutionGroups, so we're fine.

I've just tried it: it seems to ignore some namespaces (but this might be 
a Trang thing, or my RNGs) (you have to specify an output directory, 
otherwise it tries to write to "/"), but as long as you use the 
-H|--helperGen flag, the individual classes seem to come out OK. The 
Helper classes contain all the axis-specific (de)serialisation stuff that 
would otherwise get put in the classes themselves.

Unfortunately, you need rather a lot of libraries to get Axis working.

I've not found anything for Perl as yet, though.
