Re: calling method of a bean from JSP
I only used String as key.
public Object getStringMapped(String key) {
return map.get(key);
}
public void setStringMapped(String key, Object value) {
map.put(key, value);
}

this is a good point. I have not tried it. Is it ok (in terms of
performance) to use a custom class as the key, not using Java primitives
like Long ?

thanks. what i am trying to do is to get the value of a field. Say I get a
list of items:
class item {
Set values;
}
The item has a set of Values:
class Value {
Attribute attribute;
String value;
}
What I wanted to do is to get one particular value based on attribute
ID. in
this case I have to add a method in the Item class, someting like this:
String getValue (String id) {
while (it.hasNext()) {
Value value = (value) it.next();
if (value.attribute.getId().toString().equals (id)
return value.value;
}
So from JSP, I would like to call this method c:out value=${item.getValue
(id}/
c:out value=${item.value[id]}/ ?

You can't invoke arbitrary bean methods with EL; it's designed for
accessing properties, not calling arbitrary methods. The closest you can
come is to 'fake' a map-type Foo.getBar(String key) property so you
could write ${foo.bar[param]}, but that's a bit limitted.
What are you trying to achieve? Maybe you're trying to put logic in your
JSPs that more properly belongs in an action.

or

Hi,
