    database connectivity of oracle on linux


      I am using oracle server on linux box.With my code as follows:

      import java.sql.*;
      import java.awt.*;
      import java.applet.*;
      import java.lang.*;

      public class JDBCOci{
      public static void main(String[] sd){
      try {
      //Set up the Oracle JDBC driver
      Class.forName ("oracle.jdbc.driver.OracleDriver");

      Connection DB_conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORCL","scott","tiger");

      //Create a JDBC statement object
      Statement statement_obj =DB_conn.createStatement();

      //Execute a query to get the employee names from the test DB
      ResultSet results =statement_obj.executeQuery ("select ENAMEfrom EMP");

      while(results.next ()){
      System.out.println(results.getString(1)); }
      } catch (SQLException e) {
      throw new RuntimeException("SQL Exception "+e.getMessage());
      catch(Exception e){

      With this code I am getting error as :

      [root@LSERVER Abhay]# java JDBCOci
      java.lang.RuntimeException: SQL Exception The Network Adapter could not establish the connection
      at java.lang.Throwable.(Throwable.java:38)
      at java.lang.Exception.(Exception.java:24)
      at java.lang.RuntimeException.(RuntimeException.java:21)
      at JDBCOci.main(JDBCOci.java:26)

      Can somebody help me?
