WAMP MySQL Database access in java code

[Srini vas]

I have a public IP system. In that I have installed WAMP. And I have written a java code to establish jdbc connection with the mysql installed in the public ip system.

My Database connection fails miserably,

Connection con = DriverManager
.getConnection( "jdbc:mysql ://localhost/Test123","usr", "123");


If my public ip is example.com, can i try
Connection con = DriverManager
.getConnection( "jdbc:mysql ://example.com/Test123","usr", "123");

Even this fails.

My main problem is I don't know how to establish connection using java code with WAMP MYSQL Database in public ip system.

Please help me!!
