      Hi, i'm new with Oracle. I'm using JDeveloper 10g, when i try to create a database connection with the hr/hr user i get this message:

      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:ORCL


      Please, if somebpdy could give me a tip, i repeat, i'm new with Oracle. Thanks
