Subject Re: Errors occured when parsing a seemingly valid WSDL file
Date Wed, 19 Aug 2009 22:49:58 GMT

Hi Ken,

There's no native support in Xerces for loading schemas from a WSDL so
presumably you're trying to do this by extracting the individual schema
documents and then passing them to the schema loader. Am I right?

How to get it working probably isn't obvious, particularly if there are
imports between the inline schemas. You might find this JIRA issue [1]
(from a few years back) helpful.

Thanks.
