The JSP syntax for putting variables and methods outside the service method is:
<%!
private int myIntValue = 3;
private String myMethod(String arg) {
return arg.toUpperCase();
}
%>
However, a couple of cautionary notes are important:
* Your JSP page is still being invoked in a multithreaded server, so
you have to write thread-safe code. In particular, any variables you
declare this way are shared across all threads (they become
instance variables in the generated class).
* If the function you are writing is anything other than simple formatting
stuff to help you generate the HTML, I would strongly encourage you
to reconsider. Mixing business logic and presentation logic in your
pages will make your apps harder to maintain and enhance in the
future. Better choices would be to encapsulate Java logic in beans,
custom tags, or servlets.
