Connector/J not working

[dutchgold92]

Program returns this error:

java.lang.NoClassDefFoundError: com/mysql/jdbc/DocsConnectionPropsHelper
Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.DocsConnectionPropsHelper

Exception in thread "main"

I've added the Connector/J JAR file to the project in Eclipse, but it just doesn't seem to be working. :(

Trying to get it working with this program:

import java.sql.*;

class Connect
{
	public static void main(String args[])
	{
		Connection conn = null;
           try
           {
               String userName = "user";
               String password = "pass";
               String url = "jdbc:mysql://host:port/database";
               Class.forName ("com.mysql.jdbc.Driver").newInstance ();
               conn = DriverManager.getConnection (url, userName, password);
               System.out.println ("Database connection established");
           }
           catch (Exception e)
           {
				System.out.println(e);
           }
           finally
           {
               if (conn != null)
               {
                   try
                   {
                       conn.close ();
                       System.out.println ("Database connection terminated");
                   }
                   catch (Exception e) { /* ignore close errors */ }
               }
           }
	}
}
