oracle thin driver conection error

[praveen kanakarajan]

im getting this error when i try to connect oracle.

java.sql.SQLException: Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=150999040)(ERR=12514)(ERROR_STACK=(ERROR=(CODE=12514)(EMFI=4))))

is it any compatibility problem bcos it has worked with oracle 8i earlier.

More likely you don't have any permissions to connect to the instance you are trying to connect to.

Hello,

The code you received 12514 is an ORA message. It means that the servicename given in the connect descriptor is not known by the TNS listener. Verify you entered the right name in the connect descriptor. Also check that that name exists in your tnsnames.ora
