Shale does use chain, but to be honest, I don't know much more about

Hello Joe all,
I have one question regarding the chain..
Am I correct to assume that The SelectInput command that comes after
ValidateActionForm in chain-config.xml should be called in case
validation fails?
How does that happen? Javadoc

Hello all,
It's interesting to have some more complex use cases to test the
chain model against...
I would offer my app as 'guinea pig' for complex cases :-)
Currently it's a small app that manage my own 'expenses' (I have a mysql
as backend and jboss 3.2.5/tomcat 5.5 as app server)to see

I am looking forward to add more complexity for 'testing' the chain..

to me putting your code out on SF in CVS, maybe as a separate branch?

Hello Joe,
I have read in a sample chain-config.xml that I have downloaded,
That RequestProcessor.processPreprocess maps now to 'LookupCommand with
optional=true'
Does that mean that, If in my webapp my
RequestProcessor.processPreProcess was doing some logic, now I have to
put that logic
No, rather than changing LookupCommand, you would put your logic into
one or more classes that are clean implementations of Command and
configure in a catalog with a name so that the existing lookup
command would find them -- either put them in catalog struts under
the name
Hello Joe,
As an aside, I think reveals an unfortunate (though minor)
shortcoming of the basic chain model: either way, you must edit the
struts chain-config.xml in order to use this behavior. I would
prefer if there were a way for users to register their preprocessing
command without having

Hello Joe,
Thanx a lot for your reply...
If you have time to try this, let me know -- but I'd be afraid that
if you defined another catalog with the name struts, it would
overwrite the base struts catalog instead of merging with it. If
that's true, then you either must edit the one
It works, but yes, you are right in the sense that If I override

I don't want to comment much, if at all, on the chain-based
implementation Marco is trying to accomplish because I am frankly not up
to speed on the 1.3 code base and so am not in a position to comment
intelligently. I'm trying to help him off the list as best I can, but
I'm actually having
However, just to level-set as far as the current 1.2.x version goes...
Thanks, Frank. That helps a lot.
I do think that it would be much easier in 1.3 than in 1.2 to solve
this without doing a forward and re-engaging the request processor; I
can see where the complexity of intervening in

I'd suggest adding a preprocessing command which recognizes the
SOAP header, as Frank described, and instead of forwarding, simply
sets a key/value pair in the ActionContext which other commands can
interpret. Then later, you could extend the PopulateForm class to
look for the flag and to do

Well, the difference between extending PopulateForm and putting a
command after it which re-populates in the case of a SOAP request is
small; the only caveat being that in the add-a-command-after model you
must do it after or the existing PopulateForm action would clobber

Absolutely. One thing that would be nice, and maybe it already is
and I just don't know enough yet, is to be able to essentially
restart the chain at any

I'm not sure I think that would be nice ;-) Seems kind of risky, in
that it adds a lot of indeterminacy. That's the main reason why lots of
us are down on request chaining too.
Just talking about the chain pattern generically... think about trying
