java.sql.SQLException when trying to connect to Oracle database

My problem is that i attempt to connect to a remote Oracle database. Its version is 9.2.0.6, i use jdk 1.7 and ojdbc14.jar .

This is the code :

Connection connection = null;

    try {

        connection = DriverManager.getConnection("jdbc:oracle:thin:@//10.130.34.3:1522/myDB", "binette","Passer");

    } catch (SQLException e) {

        System.out.println("Connection Failed! Check output console");
        e.printStackTrace();
        return;

    }

And i got this error :

Connection Failed! Check output console
java.sql.SQLException: Exception d'E/S: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153093632)(ERR=12514)(ERROR_STACK=(ERROR=(CODE=12514)(EMFI=4))))

I tried to chande the jdbc jar to classes12.jar but it is the same error. I have already search on internet but I can't figure out the problem.Any idea please?

Solution

  • Looks like ORA-12514: TNS:listener does not currently know of service requested in connect descriptor(according to error code). So maybe your service name isn't myDB?
