I'm running into a similar error this in 5.3.2. Given the line number, it
would appear that Document is null.
51: final Document document =
saml10ObjectBuilder.constructDocumentFromXml(requestBody);
52: final Element root = document.getRootElement();
When looking in the constructDocumentFromXml, I find the cause: Way to go
with the catch(Exception e) { return null; }.
/**
* Construct document from xml string.
*
* @param xmlString the xml string
* @return the document
*/
public static Document constructDocumentFromXml(final String xmlString) {
try {
final SAXBuilder builder = new SAXBuilder();
builder.setFeature("http://xml.org/sax/features/external-general-entities";,
false);
builder.setFeature("http://apache.org/xml/features/disallow-doctype-decl";,
true);
return builder.build(new ByteArrayInputStream(xmlString.getBytes(Charset.
defaultCharset())));
} catch (final Exception e) {
return null;
}
}
