Re: JSTL and scope

[Mark Lowe]

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
<c:out value="${mykey}" />
which will return the value of the given key.
also
<jsp:useBean id="yourbean" class="com.yourdomain.yourpackage.YourClass" 
scope="request" />

<c:out value="${yourbean.yourproperty}" />
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"%>
<c:out value="${MyClass.TEST}"/>
you don't get any output.
If you add:
<%
pageContext.setAttribute("test", MyClass.TEST);
%>
and change the JSTL to:
<c:out value="${test}"/>
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
