RE: Conditional choice of action mapping based on html FORM and S ELECT tag

[Jason Haase <Jh...@CQOS.COM>]

One way you can do it is to use ActionForward's to direct to another action
instead of a jsp.  Define an action to "redirect" your requests like this.

<action  path="/planner"
          type="planner.PlanAction">
 <forward name="showReleases"  path="/showReleases.do"/>
 <forward name="showTestPlan"  path="/showTestPlan.do"/>
</action>

Then define an action for each forward from above.

<action  path="/showReleases"
          type="planner.ShowReleasesAction">
 <forward name="success"  path="/ShowReleases.jsp"/>
</action>
<action  path="/showTestPlan"
          type="planner.ShowTestPlanAction">
 <forward name="success"  path="/ShowTestPlan.jsp"/>
</action>

Finally, write planner.PlanAction to forward to the correct action based
upon the menu choice.

if(/* User picked ShowReleases */)
	return (mapping.findForward("showReleases"));
else if (/* User picked ShowTestPlan */)
	return (mapping.findForward("showTestPlan"));

Subject: Conditional choice of action mapping based on html FORM and
SELECT tag


Hi,

This is a newbie question. I am creating a web 
application where each page contains a pull down
menu of commands (SELECT). I want the users choice 
of menu item to invoke the next action object.
Because the FORM tag allows only one action, I 
want that to be mapped to multiple actions in the
struts-config.xml file. An example of what I'd
like to do is below.

Does anyone have a solution to this? I really need 
your help because I am working without access to 
other java or web programers.

Thanks - Ellen
