Re: Passing Parameters from Action to JSP's
You should use an ActionForm to store parameters. Your hidden fields can
get the value from the request like this:
%-- hidden field (mode is one of create, edit, or view) --%
html-el:hidden property=myParameter
value=${requestScope.myForm.myParameter}/
Of course there are other ways to do it but once you have more than your
two params you won't want to be juggling them around on the request
Struts even puts the form on the request for you so you don't have to do
it yourself.
Hope that helps

Subject:Passing Parameters from Action to JSP's
Hello All,
I have a issue here. Any help would be of great help.
I have an action class - Action_A which forwards the request to A.jsp.
A.jsp has 2 query parameters that are displayed correctly. The two
parameters are stored in hidden variables within the form tag. Now, when
this page is submitted, it calls Action_B which again forwards the
request back to A.jsp. But this time, the query parameters are lost! Is
there a way to send these two parameters from the Action class back to
JSP? Is it legal to do something like this? Or is there a better way to
achive this.?
Regards
Sam

RE: Passing parameters between forms
Carey, Thanks for your mail. I knew about the option you suggested and mentioned it in my mail. quote: I know I can save the foo attribute into session in Action A class and access it in Action B, or set the scope of Form A to session in struts-config and access Form A from Action B. unquote: However, the disadvantage of this option is that I need to use session scope for the forms, which I would like to avoid. I also know it is possible to pass the form attribute as a request parameter as follows: html:link page=Action B?parameter=value But, this allows the user to see the parameters being passed. I would rather use buttons for the link and post the form. Do you have any suggestions/comments?

My preference is to emulate the session functionality in your own classes, i.e. publish / subscribe. Stick a static map in your class and use a unique key generated from objects both threads are aware of to index the object, then you can pull it out when you need to. Synchronize if you need to as well. I like this better because then you can run junit tests w/o worring about the container.

This approach might work for a small system, but I would not encourage it for a large business app. If I follow you correctly, this assumes that subsequent pages will be served by the same container.

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 or object from one action to other
Isn't this just action chaining using HTTP instead of within the jvm?
I'm not sure I get the reasons why action chaining is inherently a bad
idea, though I do get that there are potential pitfalls if misused, but
that's true of many patterns. Can you explain? Or point me to an article
that explains? Thanks.

The other alternative - suitable for string parameters - is to make them
request parameters by appending to the url.
To do this you create a new forward based on the existing forward. ie in
your action:
ActionForward forward = mapping.findForward(myforward);

RE: Passing parameters to Actions
Have looked at extending ActionConfig? You could add a field for assigning roles.

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.

No need for that either since the superclass constructor is implicitly called.

RE: Passing parameters directly to Action Servlet
You can use the query string to pass parameters to your Action class: http://www.whatever.com/myapp/myaction.do?color=red Then use request.getParameter(color) to retrieve the query parameter in the Action class. In this case you are still using an Action class not Action Servlet. Don't confuse ActionServlet with Action class. The .do request is sent to your subclass of Action by the ActionServlet object as defined in your struts-config.xml file. You could use an ActionForm as well. In the above example, it would have a setColor() method that would get called when the above URL as accessed.

RE: passing parameters
Alternatively, I believe that the Action class supports a parameter attribute, which you could possibly use if the Action class doesn't use it itself. -Original Message- From: Albertsen, Juergen [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 28, 2002 8:27 AM To: 'Struts Users Mailing List' Cc: Bridges, Edward Subject: AW: passing parameters You have to use a custom Mapping class. Depending on whether you use Struts 1.0 or the 1.1-dev prerelease you either specify the mapping class globally or for each action mapping. In case of the former - 1.0.x - you use an init parameter called mapping when configuring the Action servlet in the web.xml descriptor. In case of the latter - 1.1-dev - you would use the className attribute in the action element of the struts-config. (BTW, is there any elegant way to globally set the mapping class to be used? I could not find one). This mapping class should provide the properties in question and appropriate getter and setter methods (in your case needsLogin). In the perform() method of your Action class you can then cast the mapping parameter to your custom mapping class and retreive the value for the property.
