Hi , thanks for the response but I had already been to this page with this exception and if you take a look at the code that is given there then you will notice that they have used a variable by the name mySession which they have provided no reference for as how did they implemented or referenced it. I mean they didn't instantiate it and have made a direct use of it in the code . This again hangs me back .
