your MultiMap class does not have getKey() method which translates to.

Subject: Map iterate problem
I have a Map which I place into the Application Context using the following
line in a plugin init:
servlet.getServletContext().setAttribute("mm", new MultiMap());
The map is:
public class MultiMap
{
public Map values = new HashMap();
public void setValue(String key, Object value) {
values.put(key, value);
}
public Object getValue(String key) {
return values.get(key);
}
public MultiMap()
{
values.put("foo","bar");
values.put("you","me");
}
public Map getMap()
{
return values ;
}
}
In the JSP I try to iterate over this map using (which doesn't throw any
exceptions):
However When I try to use
I get:
javax.servlet.jsp.JspException: No getter method for property key of bean
mm
What am I missing ?

Re: Map iterate problem Application Scope
I actually had this problem with other objects (not necessarily maps)
and it turned out that the logic and bean tags would only find my
objects if I set them in the pageContext object, meaning I would have to
do this in my JSP:
<% pageContext.setAttribute( "mm"
pageContext.getServletContext().getAttribute("mm"),
pageContext.APPLICATION ); %>
...
It sucked, but it worked. Essentially the tags were always looking in
the pageContext object and not the servletContext. Or maybe it was a
problem with the pageContext implementation in Tomcat, don't know which.
For JavaBeans, I could use a tag that pointed to my bean
and the tags would find it as well. So if I set a bean in session /
request scope, say in an Action, I would have to use a jsp:useBean tag
on the page that defined the bean that was already there.
