I just have a <c:out value='state.title'/> and feed the appropriate
value to the request. State is a class as follows:
public class StateContainer
implements Map {
private Map map;
public StateContainer() {
int size = 89;
this.map = Collections.synchronizedMap(new HashMap(size));
}
public void setStateContainerMap(Map map) {
this.map = map; }
public void setProperty(Object key, Object value) { map.put(key,value); }
public Map getStateContainerMap() {
return map; }
public Object getProperty(Object key) { return map.get(key); }
public StateContainer putState(String key, Object value) {
this.put(key,value);
return this;
}
public void clear() { map.clear(); }
public boolean containsKey(Object key) { return
map.containsKey(key);}
public boolean containsValue(Object value) { return
map.containsValue(value); }
public Set entrySet() { return map.entrySet(); }
public boolean equals(Object object) { return map.equals(object); }
public Object get(Object key) { return map.get(key); }
public int hashCode() { return map.hashCode(); }
public boolean isEmpty() { return map.isEmpty(); }
public Set keySet() { return map.keySet(); }
public Object put(Object key, Object value) { return map.put(key,value); }
public void putAll(Map map) { map.putAll(map); }
public Object remove(Object key) { return map.remove(key); }
public int size() { return map.size(); }
public Collection values() { return map.values(); }
public String toString() { return
"StateContainer[map=" + map.toString() + "]"; }
}
Whatever values the page author wants to be dynamic can be assumed to
be in state. Then, the Action author can make sure that the values
are there.
There is, by the way, good reason to use the composite pattern here.
I have discussed that before so I won't repeat it.
