Problems generating SchemaTypeSystem from xsds with include and/or import elements using URL

[Tine Damkjær Jørgensen <td...@netcompany.com>]

Hi,
 
I'm trying to parse an xsd containing import elements with schemalocations given as relative paths. The parsing is done using an URL as argument. When generating the SchemaTypeSystem I get the following errors:
 
* error: Could not load resource "test4.xsd" (network downloads disabled).
* error: src-resolve: element 'test4@test/namespace2' not found.
 
Doing the same thing using File instead of URL works just fine.
 
My code looks as follows:
 
  private SchemaTypeSystem generateSchemaTypeSystem(URL xsd) {
    XmlObject[] schema = new XmlObject[1];
    XmlOptions po = new XmlOptions();
    po.setCompileDownloadUrls();
    try {
      schema[0] = XmlObject.Factory.parse(xsd, po);
    } catch (XmlException e) {
      System.out.println("[Validation:generateSchemaTypeSystem] XmlException: " + e.getCause());
      e.printStackTrace();
      return null;
    }
    catch (IOException e) {
      System.out.println("[Validation:generateSchemaTypeSystem] IOException: " + e.getCause());
      e.printStackTrace();
      return null;
    }

    return generateSchemaTypeSystem(schema);
  }
 
 private SchemaTypeSystem generateSchemaTypeSystem(XmlObject[] schema) {
    SchemaTypeSystem sts;
    Collection compErrors = new ArrayList();
    XmlOptions schemaOptions = new XmlOptions();
    //schemaOptions.setCompileDownloadUrls();
    schemaOptions.setErrorListener(compErrors);
    for(int i = 0; i < schema.length; i++) {
      System.out.println("Schema no. " + i);
      if(schema[i] == null) System.out.println("Schema no. " + i + " null");
    }
    try {
      sts = XmlBeans.compileXsd(schema, XmlBeans.getBuiltinTypeSystem(), schemaOptions);
    } catch (XmlException e) {
      if (compErrors.isEmpty()) {
        System.out.println("[Validation:generateSchemaTypeSystem] XmlException: " + e.getCause());
        e.printStackTrace();
      }
      System.out.println("[Validation:generateSchemaTypeSystem] XmlException: " + e.getCause() + " Schema invalid");
      e.printStackTrace();
      for (Iterator i = compErrors.iterator(); i.hasNext();) {
        System.out.println("[Validation:generateSchemaTypeSystem] XSD Error: " + i.next());
      }
      return null;
    }
    return sts;
  }
 
And my xsds looks like this:
 
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema <http://www.w3.org/2001/XMLSchema> " xmlns="test/namespace1"  xmlns:pre4="test/namespace2" targetNamespace="test/namespace1" elementFormDefault="qualified">
<xs:import namespace="test/namespace2" schemaLocation="test4.xsd"/>
 <xs:element name="test3">
  <xs:complexType>
   <xs:sequence>
    <xs:element name="elem1" type="xs:string"/>
    <xs:element ref="pre4:test4"/>
   </xs:sequence>
  </xs:complexType>
 </xs:element>
</xs:schema>
 
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema <http://www.w3.org/2001/XMLSchema> " xmlns="test/namespace2" targetNamespace="test/namespace2" elementFormDefault="qualified">
 <xs:element name="test4" type="type4"/>
 <xs:simpleType name="type4">
  <xs:restriction base="xs:string"/>
 </xs:simpleType>
</xs:schema>
 
Does anyone know how I can solve my problem?
 
Thanks in advance,
 
Tine
