An xsd including another xsd throws a NPE on deployment
-------------------------------------------------------

                 Key: ODE-241
                 URL: https://issues.apache.org/jira/browse/ODE-241
             Project: ODE
          Issue Type: Bug
          Components: Axis2 Integration
    Affects Versions: 1.1.1
            Reporter: Matthieu Riou
             Fix For: 1.2


There's a ws-commons XmlSchema bug giving us some problems with some relative XSD includes,
the original stack is reproduced below. The situation is basically:

WSDL -> XSD1 -> XSD2

The baseUri we get from the SchemaBuilder to resolve XSD2 is wrong as it's resolved relatively
to the WSDL instead of XSD1. I wish it was simple to fix but actually it's not as it's more
of a design issue in XmlSchema. All imports within a WSDL document (including transitive ones
like we have here) are associated to a single XmlSchemaCollection. And the baseUri used for
all resolving is the one of the collection. They should either have a collection per document
or associate a baseUri with the document instead of the collection.

I filed a WS-COMMONS bug for this but as you can see they don't seem to get the problem: https://issues.apache.org/jira/browse/WSCOMMONS-265

Matthieu Riou - 17/Oct/07 04:19 PM This is unfortunately a ws-commons XmlSchema bug, the original
stack is reproduced below. The situation is basically: WSDL -> XSD1 -> XSD2 The baseUri
we get from the SchemaBuilder to resolve XSD2 is wrong as it's resolved relatively to the
WSDL instead of XSD1. I wish it was simple to fix but actually it's not as it's more of a
design issue in XmlSchema. All imports within a WSDL document (including transitive ones like
we have here) are associated to a single XmlSchemaCollection. And the baseUri used for all
resolving is the one of the collection. They should either have a collection per document
or associate a baseUri with the document instead of the collection. I'm going to file a bug
for XmlSchema for now. Apparently it's only been reported by one person in the community and
there's a workaround. If a customer have the same problem or if more people run into it, we
might have to consider fixing it ourselves. 15:20:11,083 DEBUG [ODEAxisService] resolveEntity:
