Question

i set a static field in jsp page a.jsp:

<%!
public static int A=123;
%>

how can i get this static variable A in other JSP file? (do not include a.jsp)

it is possible?

thanks for help 🙂

Answer 1

Don’t do this. Put the variable into a larger^† scope, either request, session, or application scope. Using JSTL (because scriptlets are generally bad practice):

<c:set var="A" value="${123}" scope="application" />

More on scoped variables.

_{^†By “larger,” I mean “larger than page” scope. Page scope is the default for variables created using <c:set/>, e.g. when no scope is specified.}
