yes u r correct in both the things
1) Depricated Warning did not affect anything.
2) it is encodeRedirectURL(String s) (newer version)

I found out the error Later in the Evening. My code had the
bug and was cosing this encodeRedirectURL() to be called
twice for diffrent pages. Second one being the source page
itself. since responce object was alread sent, hence it
said "IllegalStateException
> in: R(
> >  + /servlet/testchain1 + null) Response has already
> been committed"

because encodeRedirectUrl(s) just sends the request &
continues to work on the code following it.

I removed this error & even encodeRedirectUrl worked fine. 
Thanks for u'r Help.

Deepak
