trouble with getGrammarDocument()

[ibrahim <ib...@natlab.research.philips.com>]

Hi all,

I tried this code below to get the SchemaGrammar document. Somehow it keeps on
returning null. Can't figure out what's going wrong there.

could you plz reply asap since I need it urgently ?

thx a a lot,

  String namespaceKey="http://at.com/SXE";
  Grammar g = gr.getGrammar(namespaceKey);
  System.out.println("Grammar  : " + g);
  System.out.println("Grammar: " + g.getGrammarDocument()); //this one gives null
  return null;
