title: How to disable DTD fetching using JAXB2.0
body: <p>I'm trying to use JAXB to unmashall some XML which I used xjc to create in the first place. I don't want to do any validation on the unmarshalling, but even though I have disabled the validation according to the JAXB documentation with <code>u.setSchema(null);</code>, but this hasn't prevented a <code>FileNotFoundException</code> being thrown when it tries to run and can't find the schema. </p>
  
  <pre><code>JAXBContext jc = JAXBContext.newInstance("blast");
  Unmarshaller u = jc.createUnmarshaller();
  u.setSchema(null);
  return u.unmarshal(blast)
  </code></pre>
  
  <p>I've seen similar questions for disabling SAX parsing from validation by setting the apache property <code>http://apache.org/xml/features/validation/schema</code> to <code>false</code>, but I can't get the Unmarshaller to use my own sax parser.</p>
