Here is one way I did it using LookDispatchAction I am sure there are other
ways to do this also:
in my "next" section of the LookupDispatchAction I put:
public class AddPSLUserWizardAction extends LookupDispatchAction {
public ActionForward next(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response)
throws Exception {
WizardForm wizardForm = (WizardForm) form;
if (...something terrible is happening....)
return mapping.findForward("badnext");
else
return mapping.findForward("next");
}
then the badnext will forward to what ever section of the action mappings you
choose:
<forward name="badnext" path="/ViewStep1.do" />
<!-- Wizard Mapping -->
<!-- Step 1 -->
<action path="/ViewStep1"
name="wizardForm"
scope="session"
type="org.apache.struts.actions.ForwardAction"
input="/step1.jsp"
parameter="/step1.jsp"
validate="false" />
<action path="/ProcessStep1"
name="wizardForm"
scope="session"
type="edu.nmsu.psl.userwizard.AddPSLUserWizardAction"
validate="true"
input="/step1.jsp"
parameter="methodToCall">
<forward name="next" path="/ViewStep2.do" />
<forward name="badnext" path="/ViewStep1.do" />
</action>
<!-- Step 2 -->
<action path="/ViewStep2"
name="wizardForm"
scope="session"
type="org.apache.struts.actions.ForwardAction"
validate="false"
input="/step2.jsp"
parameter="/step2.jsp" />
<action path="/ProcessStep2"
name="wizardForm"
scope="session"
input="/step2.jsp"
type="edu.nmsu.psl.userwizard.AddPSLUserWizardAction"
validate="true"
parameter="methodToCall">
<forward name="previous" path="/ViewStep1.do" />
<forward name="next" path="/ViewStep3.do" />
</action>
<!-- Step 3 -->
<action path="/ViewStep3"
name="wizardForm"
scope="session"
input="/step3.jsp"
validate="false"
type="org.apache.struts.actions.ForwardAction"
parameter="/step3.jsp" />
<action path="/ProcessStep3"
name="wizardForm"
scope="session"
input="/step3.jsp"
validate="true"
type="edu.nmsu.psl.userwizard.AddPSLUserWizardAction"
parameter="methodToCall">
<forward name="previous" path="/ViewStep2.do" />
<forward name="finish" path="/wizard_done.jsp" />
</action>
</action-mappings>
I hope this helps.

Subject: wizard-style form and validator
Hello,
I'm building a wizard style webapp with 3 pages. I'm using the page
attribute to make validator check inputs.
I've got this problem :
first page validate an userId selection (required)
When this rules failes on page 2 or 3 (let's consider the user has used
a bookmark), I'd like struts to go back to page 1. How to configure my
action-mapping for this as I only have one "input" attribute, without
paging support ?
