JDBC and SQL server 2000

[panayotisk]

I need to pack my application that uses an SQL server 2000 DB and move it to a user's computer. My code is:

// Connection string
    String conStr = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=Video Club;User=VClub;Passwd=VClub";

    public void NewCustomer(String firstName,
                            String lastName,
                            String phone,
                            String address) {
        // SQL Query string
        String query = "EXEC prc_NewCustomer N'" + firstName +
                       "', N'" + lastName + "', N'" + phone +"', N'" + address + "'";

        try {
            // Load the JDBC driver
            Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
            Connection con = DriverManager.getConnection (conStr);

            // Get a connection
            Statement stmt = con.createStatement();

            // Execute query
            stmt.execute(query);

            con.close();
        }
        catch(ClassNotFoundException esql){
            esql.printStackTrace();
        }
        catch(SQLException esql){
            esql.printStackTrace();
        }
    }

The problem with this code is that the user's computer should have sa with empty password. Is there a way to use Windows authentication? Or if not how should I add a user in SQL server wirh appropriate rights so that my application may use this login to connect?
