Hi Remy,

I set up a test case and it looks like it's a Tomcat-5 problem.
The webapp works on Tomcat-4.1, on Tomcat-5.0 the resources within
xsd.resources.jar cannot be reached.


tested environment: Win2k Prof, SuSE Linux 8.2

Log Win2k:

The webapp is here:
http://tamino.demozone.softwareag.com/xsdTestCaseWebApp.zip

The JavaDoc for the relevant classes is here:

Eclipse EMF:
http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E/emf-home/docs/j
avadoc/index.html
Eclipse XSD:
http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/xsd-home/docs/javado
c/index.html

This is how the URI to the xsd resource in xsd.resources.jar is created
(from XSDSchemaImpl.java):

          String baseURL = XSDPlugin.INSTANCE.getBaseURL().toString();
 
getGlobalResourceSet().getLoadOptions().put("XSD_MAGIC_XML_SCHEMA",
XSDConstants.SCHEMA_FOR_SCHEMA_URI_2001);
          Resource magicSchemaForSchema2001Resource = 
            getGlobalResourceSet().getResource
              (URI.createURI(baseURL +
"cache/www.w3.org/2001/MagicXMLSchema.xsd"), true);


Best regards,

Jan
