Oracle Database Discussions

I am trying to connect to Oracle 11 DB from Squirrel SQL.
I am using proper steps but getting this error:

My SQL Plus is working fine and
select INSTANCE_NAME from V$INSTANCE; gives me "orcl"

and my id/password is also okay.


On command prompt also-it's working fine:

But getting this error.

I am using right DB driver at D:\app\product\11.1.0\db_1\jdbc\lib\ojdbc6.jar which is 1932 KB

and i have this DB:

SQL*Plus: Release 11.1.0.6.0 - Production on Tue May 12 23:31:58 2009

on windows vista

This is my connection string
jdbc:oracle:thin:@localhost:1521:orcl

also i checked the services and TNSListener is also working fine
