RE: Passing Parameters Between Actions
snip Is there any reason you are forwarding from JSP? /snip JSP where got? He stated quite clearly he is forwarding from one action to another using (returning I presume) an ActionForward. snip forward name=action2 path=/Action2.do/ /snip I was going to suggest that you specify redirect=false in the forward, but looking at the javadoc it seems that that is the default already! Hmm.. Try it anyway and see if it works as it sounds very much like your doing a client side redirect :-) If it really is doing a server side redirect you should still be able to get at that parameter - the only situation I can think of where you would get these symtoms is if its a multipart request and the first action has an actionform associated with it and the second does not. (If if that parameter is due to some other request wrapper implementation). That doesnt explain the attributes not working though. It really does sound like your doing a client side redirect. Hmmm... just checked the source and its definately default to redirect=false. Ok, I give in... btw: its considered bad practice to chain actions in this manner.

RE: Passing parameters to Actions
parameter is also used for ForwardAction. Actually, any action can access its parameter using mapping.getParameter() and use it however it wants. We do this in several actions. From the ActionConfig javadoc: parameter protected java.lang.String parameter General purpose configuration parameter that can be used to pass extra iunformation to the Action instance selected by this Action. Struts does not itself use this value in any way. However, Sloan, you ar right that it is limited to passing one parameter and that the parameter's intended use is unclear if it is simply called parameter. Brandon's solution to subclass ActionMapping is probably the best (only reasonable?) alternative.

RE: Passing parameters to Actions
It may be easier for you to extend RequestProcessor and override processRoles(...) and perform your own authorization there. I started down that road, but didn't like the effect of return false from processRoles, so we always return true and do the real role checking in our base action class (mapping.getRoleNames() gives us the value of the roles attribute) so that we can return mapping.getInputForward() when the role check fails... -- Voytek Jarnot Quidquid latine dictum sit, altum viditur. -Original Message- From: Sloan Seaman [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 25, 2003 2:29 PM To: Struts Users Mailing List Subject: Passing parameters to Actions In the struts-config.xml file I want to pass a few parameters to my actions but it looks like the DTD only supports one parameter tag.

RE: Passing parameters to Actions
It is done automagically upon startup of your application. When struts
processes it's config (struts-config.xml) it generates ActionMapping
instances for each action. When you specify your extended ActionMapping in
the className attribute of action struts will populate the related
property or properties of that class. Your extended Action mapping must have
matching getter/setter properties that match you property= value (i.e.
set-property property=aProperty value=aValue/ relates to public
setAProperty(String aValue){};)
One of the issues you might run into is that you cant easily change the
properties during runtime. If you make role changes to the Action you will
have to reboot the webapp. This is usually not a major deal.

In the struts-config.xml file I want to pass a few parameters to my
actions
but it looks like the DTD only supports one parameter tag.
I.E.:
action path=/app/main
type=com.symbol.mobilecommerce.analysis.actions.app.Main
name=app.main
parameter=admin
forward name=PAGE_SRC path=/app/main.jsp/
forward name=PAGE_ACCESS_DENIED path=/index.jsp/

When I would rather do something like:

name=app.main
forward name=PAGE_SRC path=/app/main.jsp/
forward name=PAGE_ACCESS_DENIED path=/index.jsp/
parameter name=ROLES_ALLOWED value=admin/
/action
Now, I know there is a roles attribute but we are doing out own security
model and are not using request.isUserInRole().
(BTW: is there any way to write to whatever request.isUserInRole() used to
do its lookup so we can use it?)
Is there any way to have parameters passed like how I would like?
I could spoof forward to something like forward name=ROLES_ALLOWED
path=admin/ but I would rather not.

Ok. sounds like a plan. Question though:
How do I access the set-property information? Do I have to parse the
XML
or something?
Sorry... I'm a bit new to Struts...

Subject: RE: Passing parameters to Actions
parameter is only used for dispatch actions. If you want to set
properties
for an action... you can extend the ActionMapping class and use the
set-property in an action element while specifying the className
attribute
of the action element.

Subject: Passing parameters to Actions
In the struts-config.xml file I want to pass a few parameters to my
actions
but it looks like the DTD only supports one parameter tag.
I.E.:
action path=/app/main
type=com.symbol.mobilecommerce.analysis.actions.app.Main
name=app.main
parameter=admin
forward name=PAGE_SRC path=/app/main.jsp/
forward name=PAGE_ACCESS_DENIED path=/index.jsp/
/action
When I would rather do something like:
action path=/app/main
type=com.symbol.mobilecommerce.analysis.actions.app.Main
name=app.main
forward name=PAGE_SRC path=/app/main.jsp/
forward name=PAGE_ACCESS_DENIED path=/index.jsp/
parameter name=ROLES_ALLOWED value=admin/
/action
Now, I know there is a roles attribute but we are doing out own
security
model and are not using request.isUserInRole().
(BTW: is there any way to write to whatever request.isUserInRole() used
to
do its lookup so we can use it?)
Is there any way to have parameters passed like how I would like?
I could spoof forward to something like forward name=ROLES_ALLOWED
path=admin/ but I would rather not.
Thanks!

RE: Passing parameters to Actions
I wonder if MyExtendedActionMapping is as simple as:
public class MyExtendedActionMapping extends ActionMapping {
private String xxx;
public void setXXX(String xxx) { this.xxx = xxx; }
public String getXXX() { return xxx; }
}
Should I implement any other method...?
Thanks.

RE: Passing parameters to Actions
maybe a super() call in the constructor. But you shouldn't need anymore than
that.

RE: Passing parameters to Actions
No, that's it.
1. Make your class extending o.a.s.a.ActionMapping
2. Add className=my.package.MyActionMapping to your action
3. Add your set-property property=xxx value=Whooo hooo!!!/

Re: Passing parameters to Actions
Well, I'm sure it's a typo, but make sure the methods are called
setXxx(String) and getXxx()..! :)

RE: Passing parameters to Actions
No need for that either since the superclass constructor is implicitly called.
