All parsers support setting the schema location(s) through the SAX API using 
properties. Such settings override those present in the document.

Using JAXP 1.2 properties for schema validation (supported by Xerces 2.2+) and 
JDOM Beta 9 RC x:

    SAXBuilder builder = new SAXBuilder(true);

    builder.setProperty(
       "http://java.sun.com/xml/jaxp/properties/schemaLanguage",
       "http://www.w3.org/2001/XMLSchema");
    builder.setProperty(
       "http://java.sun.com/xml/jaxp/properties/schemaSource",
       new String[] { "soap-envelope.xsd", "weblog.xsd" });

    builder.build(...);

Hope this helps,
