"sushil java",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!

1) Please see Bear's request above.
2) Please don't post the same question in multiple forums, I'll close the other ones to prevent duplicate conversations.

3) There is a list of free webservices for stocks here
