get static variable from class into JSP tag scope

[Robert Mark Bram]

Hi All,

I have a static variable in a class that I wish to share with some of
my JSP code. Can I use the <jsp:useBean> (or any tag?) to get that map
into the scope of my JSP tags?

Thanks for any assistance,

Rob

<jsp:useBean> requires that the bean be in scope, i.e., entered into the
context of the page, request, session or application, e.g., via
<http://java.sun.com/javaee/5/docs/a...Attribute(java.lang.String, java.lang.Object)>

You can also use Expression Language (EL) to access such beans.

You could also use scriptlet, but don't.

You could also use Java Server Faces (JSF), which has a way to directly
connect component attributes ('value', 'binding', 'action') to bean methods
and attributes. There is a learning curve involved there.

try
<%@ page import = "yourpackage.YourClass" %>

try
<%@ page import = "yourpackage.YourClass" %>

And after that:
<%= YourClass.VALUE %>

Hi Hal,

try
<%@ page import = "yourpackage.YourClass" %>

Sorry, I should have been more specific - I wanted to get the value
into the scope of my jsp tags, not a scriptlet. Thank you for your
response though.

Thank you Lew,

<jsp:useBean> requires that the bean be in scope, i.e., entered into the
context of the page, request, session or application, e.g., via
<http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletRequest.ht...)>

This supports the MVC pattern quite strongly, so I am not as
disgruntled as I was at first - now I see a reason for it.
