MalformedURLException - no protocol - when reading schema with recursive schema
imports
---------------------------------------------------------------------------------------
Key: XMLSCHEMA-21
URL: https://issues.apache.org/jira/browse/XMLSCHEMA-21
Project: XmlSchema
Issue Type: Bug
Affects Versions: XmlSchema 2.0.1
Environment: Windows7
Reporter: Arik Goldstein
I have the following xsd files:
schema1.xsd - contains import to schema2.xsd
schema2.xsd
schema3.xsd - contains import to schema1.xsd
imports are with relative paths (plain file name, all schema files are in the
same directory)
Reading of schema1 and schema2 works fine.
Reading of schema3 fails with the following exception and call stack:
Caused by: java.lang.RuntimeException: java.net.MalformedURLException: no
protocol: schema1.xsd

Debugging shows that:
* when reading schema1.xsd and resolving schema2.xsd (in
SchemaBuilder.resolveXmlSchema), the baseUri is file and the operation succeeds
* when reading schema3.xsd and resolving schema1.xsd->schema2.xsd, the baseUri
is plain text (schema1.xsd) and not file (file:/c:/schema1.xsd) and the
operation fails
Workaround: use full path in the schema location (c:\schema1.xsd instead of
schema1.xsd) fixes the problem.
However this workaround is ugly and the recursive import should work without
it.
I would be glad to hear your opinions.
Thanks in advance,
Arik Goldstein
