Hi ,
I'm back with a new question.I want to export the graph into GEXF format. I tried something like this, but its giving a null pointer exception.
                Graph g = new SingleGraph("");
                FileSinkBase fsb = null;
FileWriter f = new FileWriter("out.txt");
PrintWriter pw = new PrintWriter(f);
fsb.writeAll(g, pw);
Please help  me regarding this and how to export it.

Rajesh V.
