Loading a schema that refers to another one.

[Darrin Smith]

I have a schema that includes another one: <xsd:include schemaLocation="SchemaCommon.xsd" />

I am using a document builder to validate my XML like this:

        //Use Spring to get to the main Schema
        ClassPathResource res = new ClassPathResource(SCHEMA_SOURCE); //This is the main (containing) schema. The one that includes SchemaCommon 
         
         factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource",
                              res.getFile());
      
         DocumentBuilder builder = factory.newDocumentBuilder();

         SimpleErrorHandler handler = new SimpleErrorHandler();
         
         builder.setErrorHandler(handler);

         Document doc = builder.parse(new InputSource(new StringReader(email)));

When I run this, I get:

schema_reference.4: Failed to read schema document 'SchemaCommon.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
src-resolve: Cannot resolve the name 'RecordType' to a(n) 'type definition' component.
...


Is there a way to append the schema files together somehow?

Try <xsd:import schemaLocation="SchemaCommon.xsd" />

I'm guessing your problem is in line 5 of the code you posted. Does that res.getFile() method return a complete URL, or just the file part of the URL? I'm guessing (guessing again) that you need to pass a URL as the value of that attribute and not just a file path. That would definitely be true if the URL referred to a jar entry, but you didn't say anything about that.

BINGO to using import instead! That did the trick.

Thanks.
