I've just started looking at using JSTL in my struts app. On the whole it
looks interesting but I've run up against a problem that I've been asking
about on the taglibs list today.
How do you access scoped attributes that have dotted names? E.g.
org.apache.struts.action.ACTION_MESSAGE.
If you try to access this object using the EL, it attempts to interpret the
name as if it were a nested set of beans. <c:out
value="${org.apache.struts.action.ACTION_MESSAGE}/> would try to do this:
org.getApache().getStruts().getAction().getACTION_MESSAGE();
... which is obviously nonsense.
If you know the scope that the bean is in, you can use an alternate syntax:
<c:out
value="${requestScope[\"org.apache.struts.action.ACTION_MESSAGE\"]"} />
But, there does not seem to be any way to access a bean if you do not know
(or want to specify) the scope. Has anyone come up against this before? Is
there a straightforward solution or do we have to abandon dotted notation
for scoped attributes?
