Ok, tearing my hair out right now and extremely confused.
If you look at the Java Technology Forums you will see a rather nice little pattern that
someone called evnafets has created, it allows you to use a single Constants class
both in your Actions and in your JSP pages ...
It uses reflection to add it's static final members to a map which can then be accessed by JSTL like so
<c:out value="${Constants.FOR_RENTAL_PROPERTIES_SELECTION}"/>
The address is http://forum.java.sun.com/thread.jsp?forum=45&thread=508847&message=2415101 <http://forum.java.sun.com/thread.jsp?forum=45&thread=508847&message=2415101>
This works with a lot of stuff but the jstl and struts tags seem to be a little inconsistent in their behaviors.
For example this works ...
snip=
<html:select property="propertyTypes" multiple="true">
<html-el:optionsCollection name="${Constants.PROPERTY_TYPES_SET}" value="id" label="name"/>
</html:select>
=snip
But for some reason ( my stupidity and the time of the evening ) I cannot get this to work.
snip=
<c:set var="emailNotifications" value="${scope['Constants.EMAIL_NOTIFICATIONS']"></c:set>
<c:out value="${emailNotifications.priceRangeStart}"/>
=snip
or like this
snip=
<c:set var="emailNotifications" value="${scope[${Constants.EMAIL_NOTIFICATIONS}]"></c:set>
<c:out value="${emailNotifications.priceRangeStart}"/>
=snip
I'm starting to feel like I'm back in my Perl days again .... Is there a way that I can dereference these
beans or do I have to use sloppy string literals in my jstl code ?
Any suggestions or am I just stupid to want to do this ?
