Saxon

We have Saxon-EE for schema validation. I am currently experimenting with it, but having a problem with xsd import statements.

As a basic test case, I have a main.xsd file in my classpath under the folder /test-schemas using xs:import to grab a.xsd and b.xsd (each with different namespaces) that reside in the same /test-schemas folder.

I have previously gotten the imports to work in JAXP/Xerces using a custom ResourceResolver. However I'm struggling to do this with the pure Saxon-EE API, and I can't find any examples.

The SchemaManager doesn't seem to natively understand classpaths, so I have been trying to use the SchemaURIResolver to no avail.

Here is my code:

@Test
public void saxonValidationTest() {

   try {
      Processor proc = new Processor(true);
      proc.setConfigurationProperty( "http://saxon.sf.net/feature/validation-warnings", "true");
			
      SchemaManager schemaManager = proc.getSchemaManager();
      SchemaURIResolver resolver = new StandardSchemaResolver(new EnterpriseConfiguration());
      URI baseUri = new URI("classpath:///test-schemas");
      resolver.resolve("urn:testing:message:typea, urn:testing:message:typeb", baseUri.toString(), new String[]{"./"});
      schemaManager.setSchemaURIResolver(resolver);

      InputStream is = this.getClass().getResourceAsStream( "/test-schemas/main.xsd");
      schemaManager.load(new StreamSource(is));

      ...			
   } catch (Exception e) {
      fail(e.getMessage());
   }
}

This is the output I get from the failing exception message:

Warning: at xs:import on line 6 column 76 
  Imported schema document a.xsd cannot be located: java.io.FileNotFoundException
  (/home/afbagwe/workspaces/osgi/framework/libs/core/a.xsd (No such file or directory))
Warning: at xs:import on line 7 column 76 
  Imported schema document b.xsd cannot be located: java.io.FileNotFoundException
  (/home/afbagwe/workspaces/osgi/framework/libs/core/b.xsd (No such file or directory))
Error on line 12 
  The element {kml} is referenced, but has not been declared
Error on line 13 
  The element {message} is referenced, but has not been declared

So to be clear, the code can file my main.xsd file just fine. However the returned sources, instead of searching the classpath, seem to be finding instead the absolute path on my file system but only to the top level of the Maven project I have set up.

Curiously if I modify my code to use a FileReader, it still can't find the import xsd files in the same directory. And assigning a baseURI of "src/test/resources/test-schemas/" still results in precisely the same error message above that I got trying to do a classpath.

Any help is greatly appreciated.
