Re: JSTL and scope
As this is a struts list then perhaps you'd consider using a struts
action or even perhaps a plain old servlet to do what you need.
request.setAttribute("test",MyClass.TEST);
if its a map then
request.setAttribute("mymap",map);
or even
Iterator keys = map.keySet().iterator();
while(keys.hasNext()) {
String key = keys.next().toString();
request.setAttribute(key,map.get(key));
}
...
this way you can access your properties in you page as follows
which will return the value of the given key.
also
And thus save all that importing in jsp..

Hi,
I am a little surprised that having a class variable imported into a
page isn't seen by JSTL contructs.
For example if i have a class that defines:
package com.company.test
public final class MyClass
{
public static final String TEST = "test";
}
and my JSP page has:
<[EMAIL PROTECTED] import="com.company.test.MyClass"%>
you don't get any output.
If you add:
<%
pageContext.setAttribute("test", MyClass.TEST);
%>
and change the JSTL to:
then it works.
But surely the MyClass.TEST already had page scope otherwise the
setAttribute wouldn't have seen it?
The upshot of all this is that I am iterating through a map that can
have any one of about 30 keys.
Do I really have to put all these keys into the session or some other
scope every time I load the page?
Thanks,
Andy

RE: JSTL and scope
I can see where you are coming from. I would also like to be able to call custom
methods on objects rather than just those that have getXXX.
I suppose this is all to do with JSTL adhering to strict bean specification with
everything acquired by get methods matching class members.
you would need a method called getTEST to be able to access using JSTL because doing
MyClass.TEST with JSTL violates the bean spec.
