Error: Could not find or load main class Test

[java_aim]

I got the message as the title of this thread shows.
The program I have written is as follows:

import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
import javax.swing.JOptionPane;


public class Test {
public static void main(String [] args) {
String connUrl = "jdbc:sqlserver://localhost:1433;databaseName=AdventureWorks2012;use r=sa;password=chai;";
try {
Connection conn = DriverManager.getConnection(connUrl);
}catch(SQLException e) {
JOptionPane.showMessageDialog(null,e.toString());
}
}
};


================================================== =====================

Can anyone tell me how to fix this and let the compiler find and load the main class Test successfully?

Please use [code] tags [/code] when posting code.

That is a runtime error, not a compile time error.
How are you running this?
Have you compile this already?

I have compiled this fragment of code already. So I got test.class
I ran this code by "java Test"
