Schemas with several imports for the same namespace fail to load
----------------------------------------------------------------
Key: ODE-208
URL: https://issues.apache.org/jira/browse/ODE-208
Project: ODE
Issue Type: Improvement
Components: BPEL Compilation/Parsing
Affects Versions: 1.2
Reporter: Matthieu Riou
Assignee: Matthieu Riou
Fix For: 1.2
When a process relies on a lot of different schemas it oftens happens that 2
different schema files get imported under the same namespace from two different
locations:
<xs:import namespace="urn:SMPTE:Groups:MXF"
schemaLocation="../groups/s377m_packs.xsd"/>
<xs:import namespace="urn:SMPTE:Groups:MXF"
schemaLocation="./s377m_metadata.xsd"/>
Depending on the order of loading Xerces ignores one of the imports as it
already know the namespace. Remember in the XSD spec the schema location is
just a hint, so parsers discriminate schemas based on the namespace (which also
gives some performance improvements as stuff is cached). Strictly, such schemas
are none valid but somehow users fail to see it that way.
