Craig wrote quote in a struts dev thread on chain "

In your standard processing chain, do something like this:

     <command className="org.apache.commons.chain.generic.LookupCommand
                   catalogName="foo"
                          name="bar"
                      optional="true"/>

What this does, in English, is:
* Look up a command named "bar" in a catalog named "foo".
* If such a command exists, delegate control to it
   (and do all the right stuff about filters if this is a chain)
* If such a command does not exist, silently continue

" end quote.


I do not understand how to do above.  Is that the declaration done in 
chain.xml?
This assumes that I hard code the name of command I want to go to.
(if I knew command at decleration I would just name it then, not look up).


Is there a built in way of dispatching dynamicaly?

for example: lookUpAndExecute("foo");

Hint?
