[Struts 1.3] Using Commons Chains instead of Action(s)
Hi all,
I have updated some apps to 1.3, that went pretty smooth :-)
(Thanks to the good documentation in wiki!!!)
I saw in struts-config DTD that for <action> element now the
attributes "catalog" and "command" were introduced.
I got a chain of commands to work (partly) w/ 1.3.
I now have two questions on working with chains instead of actions.
#1
How do I *caculate* the navigation inside of my command?
Or do I need something extra? After my chain of commands was
executed, I saw a blank page (yes... no ActionForward found ;-))
I have in struts-config something like that:
<action ...command="myChain" catalog="publishCat"...>
<forward name="success" ...>
</action>
Is there a "key" for the Context object, to tell him "success" must be
used for finding the ActionForward object ?
#2
This is more a doubt on accessing formbeans in a command.
In my command I did the following to lookup my formBean object
(inside execute(Context cxt)):
FormularBean fb = (FormularBean) cxt.get(Constants.ACTION_FORM_KEY);
//org.apache.struts.chain.Constants
this works pretty well, but now my doubt... is this the "right" way ?
Thanks for any hint :-)
Best Regards
Matthias Weßendorf

If you aren't already extending any other class, your commands can
inherit from ActionCommandBase, which may make the expectation that
it be used with an ActionContext more clear -- it's just a simple
command which casts the context and passes it to an abstract
execute(ActionContext) method which you'd implement in your class.
One of the intentions behind moving creation of the ActionContext
into ComposableRequestProcessor (after a brief experiment with trying
to adapt any Context) was to be able to guarantee that all commands
called by the ComposableRequestProcessor would be passed not just a
Context, but an ActionContext.

Wolfgang-
I am now doing something like this
inside of execute(Context context):
ActionContext ctx = (ActionContext) context;
...
ActionMapping mapping = (ActionMapping)ctx.getActionConfig();
ActionForward fw = mapping.findForward("success");
Since the passed ContextIMPL is ServletActionContext, I think it will be
ok... in any environment (portlet e.g)
Any comments?

Can you repackage it to, say 2MB or so, source code only?

do:
ActiionMapping mapping = (ActionMapping)
context.get(org.apache.struts.chain.Constants.ACTION_CONFIG_KEY);
ActionForward fw = mapping.findForward(forwardName);
context.setForwardConfig(fw);
Also see my Struts 1.3 dev suite (250MB download) at www.infonoia.com
(you need to register).
We wrapped the above in our own ActContext class which extends
ServletActionContext and has context.setForward(forwardName)
We also wrote a DispatchCmd, similar to DispatchAction, but for
commands, (so you have event handles like onSave(Act Context))
Also see our Struts 1.3 dev suite including svn to Struts 1.3 (250MB
download) to get a head start on 1.3 (need to register to access).
