Error in Connection
I use JDeveloper and try to connect to my Oracle database and it gives the connection error as Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=135294976)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
The connection is like this
"jdbc:oracle:thin:@localhost:1521:ORCL"
Could you please tell me where the problem is?
