Oracle.JDBC Connection Problem

[ljupce gligorov]

Hello to everyone, I'm writing for first time at this forum.
I have problem with my oracle Db connection.
In my project libraries I've loaded ojdbc14.jar.
I got 2 oracle errors.Please help.

  
public class OracleDriverLoader {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Connection conn = null;
        try {
            Class.forName("oracle.jdbc.OracleDriver");
            System.out.println("Oracle driver is loaded");
            conn = DriverManager.getConnection("jdbc:oracle:thin:ljupce/ljupce@localhost:1521:XE");
            System.out.println("Connected with: @localhost:1521:XE");
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("select sysdate from dual");
            while(rs.next())
                System.out.println(rs.getString(1));
            stmt.close();
            conn.close();
        }catch (Exception e) {
            System.err.println("Error: "+e.getMessage());
            e.printStackTrace();
        }
    }

}

Ljupce,
Welcome to JavaRanch!

That looks like a problem with the Oracle setup. If you have access to run SQL at the command line, try it there - I bet you get the same error.

According to an internet search, the problem is with your Oracle parameters (or Windows registry.) The link is really detailed - check it out.

If you don't have access to these settings, forward the link to your DBA.
