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]
