I've configured my WSAD in order to communicate to the Oracle 10.I created a servlet which will try to connect to the database (orcl).When i run the servlet i get the following error.
java.sql.SQLException: Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor The Connection descriptor used by the client was:localhost:1521 rcl
what could be the reason???I'm new to oracle.....But project doesn't care what is new and what is not
