WSIFException: no schema elements found

Hi!

I'm using wsif-2.1.0_RC2, which I foun somewhere searching
in Google
(I don't remember the site). I am using this version,
because v2.0
gave me an UnknownExtensibilityElement when I should recieve
an
SchemaElement. So I read it was a bug and I try using this
new
version.

But, with this new version I have a new exception I didn't
had with the old one.
Web Services I could invoke with no problem with old
version, now when executing
"operation.executeRequestResponseOperation(input,
output, fault)" I
recieve this exception:
