Fairly new to JSP

Sure its not called an include, but i'm still in asp mode.
Whilst running through a tutorial, I create ServletUtilities.java , which is basically an include for adding the <HTML><Head> etc for creating a HTML page.
In it is the line public static String headWithTitle(String title) {

In the next LotteryNumbers.java file I call it with
out.println(ServletUtilities.headWithTitle(title) +

but when I use javac to creat the servlet I get the error
LotteryNumbers.java:24: cannot resolve symbol
symbol : variable ServletUtilities
location: class stuservlets.LotteryNumbers
out.println(ServletUtilities.headWithTitle(title) +
^

Any ideas?
