Re: [Ikvm-developers] Class Loader Question Java->.NET

[Jeroen F. <je...@su...>]

Hi Rick,

I can think of two possibilities:

1) Your application doesn't have access to Jace.jar (I assume you're running an ASP.NET app, and that might not have access to everything on the system)

2) The Jace.jar is somehow incompatible with the IKVM zip implementation. You can test this by writing some code to manually retrieve the wsdl/FNCEWS40DIME.wsdl zip entry with the IKVM java.util.zip implementation.

Regards,
Jeroen
