Java EE (Java Enterprise Edition) General Discussion

Hey!

I would like to validate XML reports with a XSD schema. I do it like this:

SchemaFactory schemaFactory = SchemaFactory
       .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

Source schemaFile = new StreamSource(new File(MyClass.class
      .getClassLoader().getResource("mainschema.xsd")
      .toURI()));
Schema schema = schemaFactory.newSchema(schemaFile);
 schema.newValidator().validate(new DOMSource(ervBericht));

Everything works pretty well, also the importing of another xsd does not make any problems:

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="..." xmlns:typ="..." targetNamespace="..." version="0.5.2" elementFormDefault="qualified">
  <xsd:import namespace="..." schemaLocation="another.xsd"/>
  ...
</xsd:schema>

But if I create an artifact JAR out of my validation to use it as a jar library in other projects, I cannot access my resources like this. Searching the web brought me to the solution to use this snippet to get to the resources inside the jar:

Source schemaFile = new StreamSource(MyClass.class
      .getClassLoader().*getResourceAsStream*("mainschema.xsd")
      .toURI());

I did that with my properties files and other plain text files - and it worked. But using StreamSource with an InputStream as parameter brings up the problem. Suddenly I get errors complaining that it cannot find schema types defined in the imported XSD:

org.xml.sax.SAXParseException: src-resolve: Cannot resolve the name 'typ:DienststelleMenge' to a(n) 'type definition' component.

I cannot just copy those two XSD's together, I need to do it with the import tag.

Can anybody please help me?
