Serious issue/challenge with Xerces-J the XSLoader 's loadInputList method... 2006-11-25 - By Bullotta, Rick
Hello, all.
Here's a quick summary - the WSDL below contains two schema elements. I
want to create an XSModel that represents this WSDL, and the only way I
can see to do so is by extracting the schema elements separately,
turning them into LSInputs, and using the loadInputList method on the
XSLoader class. Unfortunately, it does not work - there is always an
error attempting to resolve the n0:YYY type when it attempts to create
the XSModel.
If I separate the first schema element into its own file, and import it,
it works fine. However, it should work fine in the same file as well!
:-(
I suspect it has something to do with the fact that imports within the
same "file" (in the case of loadInputList, of course, they are separate
sources), would not have a schemaLocation attribute on the import, but
only a namespace attribute (as below). I am at a loss to determine how
to handle this with Xerces.
In this case, I would expect Xerces to simply see if a model or grammar
has already been loaded for that namespace. I tried as hard as I could
to trace through the source, but I was completely lost working through
the intricacies of how these things are resolved.
Help!!!
