Hi,

My java code :

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import oracle.jdbc.OracleDriver;

public class ClassNameDemo {
    public ClassNameDemo() {
          System.out.println("Hello");
        System.setProperty("oracle.net.tns_admin","D:\\TNSNAMES.ORA");
        System.out.println("Hello");        
    }

    public void doit () throws SQLException {
          System.out.println("H");
        String usr = "MURUGANANTHAMM_CGZ_D2";
        String pwd = "MURUGANANTHAMM_CGZ_D2";
        System.out.println("He");
        //String url = "jdbc:oracle:thin:@//134.65.171.119:1521/sirdx2";
        String url = "jdbc:oracle:thin:@sirdx2";
        System.out.println("Hel");
        DriverManager.registerDriver(new OracleDriver());
        System.out.println("Hel1");
        Connection conn = DriverManager.getConnection(url,usr,pwd);
        System.out.println("Hell");
        String sql = "select sysdate from dual" ;
        System.out.println("Hello");
        Statement stmt = conn.createStatement();
        ResultSet rs = stmt.executeQuery(sql);
        while (rs.next())
            System.out.println("results: " + rs.getString(1));
        conn.close();
    }

    public static void main(String[] args){
          ClassNameDemo test = new ClassNameDemo();
        try {
            test.doit();
            System.out.println("Done..");
        }
        catch (SQLException e) {      
            e.printStackTrace();
        }
    }
}


output :

Is DatabaseError.java - your custom code ?
If it is, what is exactly line 125 ?

Discard my first question.But I think you need hist ad port in the URL, and you commented out the correct URL and left the url without host and port part
I understand that getCinnection method is giveing excepotiion because of it

This is the correct format of the URL for Orcale:

String URL = "jdbc:oracle:thin:@hostname.com:1521:dbname";

So use this:

String URL = "jdbc:oracle:thin:@134.65.171.119:1521:sirdx2;

or if it is on loacla machine:


String URL = "jdbc:oracle:thin:@localhost:1521:sirdx2;
