Connect with the server machine datadase

Guys I am using MY SQL data base system and I wanna access my server machine data base from my client machine.

I used this code to made the connection..

try {

Class.forName("com.mysql.jdbc.Driver").newInstance();

conn = DriverManager.getConnection("jdbc:mysql://10.0.0.1:3306/invoice_ijts", "root","123");

}

catch (Exception e) {

System.out.println("Error in Database Connection "+e);

}

But it doesn't work properly and give me a " Null Pointer Exception" with a flowing error message.

"Error in Database Connection java.sql.SQLException: Data source rejected establishment of connection, message from server: "#HY000Host '10.0.0.10' is not allowed to connect to this MySQL server"

some one can help me out for this matter ?
