Network adapter couldn't establish connection with the database

[Arun Somasundaram]

Hi,

I have encountered the below mentioned Exception when I try to run the following code.Here the server is running in a remote system:

SQLException : IO exception network adapter couldn't establish connection with the database

 
package jdbc;
import java.sql.*;

public class CheckConnection {

	public static void main(String[] args) {
		
		Connection con;
				
		try
		{
			Class.forName("oracle.jdbc.driver.OracleDriver");
			con = DriverManager.getConnection("jdbc:oracle:thin:@orcl:1526:orcl","scott","tiger");  
                                              
                                                if(con!=null)
                                                     System.out.println("Connection successfull");
                                                 else
                                                     System.out.println("Connection unsuccessfull");

                                }
                                
                                catch(Exception e)
		
                                {
				System.out.println(e);
		}

          }

       }

 

What can be done to resolve this problem?

Hi Arun,

Your connection string is jdbc:oracle:thin:@orcl:1526:orcl","scott","tiger
Is this correct according to Oracle specs?
is "orcl" the name of the database server?
Can you ping "orcl"?
