Answer 1

This post from the Xalan-J mailing list suggests that "the right way" is for you to configure the underlying Source/Reader yourself to disable validation.

Answer 2

Either disable DTD resolving in the parser (parser-specific) or set an empty entity resolver.

Copied from http://www.jdom.org/docs/faq.html#a0350:

public class NoOpEntityResolver implements EntityResolver {
  public InputSource resolveEntity(String publicId, String systemId) {
    return new InputSource(new StringBufferInputStream(""));
  }
}

// Then in the builder...

builder.setEntityResolver(new NoOpEntityResolver());
