How to change the input attribute in the ActionForm ?

[Jack Lau]

Hello all,
Does anyone know how to change the input attribute in the ActionForm, not in the struts-config.xml ?
// Inside struts-config.xml
<action
path="/jsp/test"
type="com.jack.TestAction"
name="TestForm"
input="/jsp/test/testStruts.jsp"
</action>
// Inside ActionForm
public ActionErrors validateChangePassword(ActionMapping mapping, HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (true) {
errors.add("test", new ActionError("id_not_match");
// want to chnage the input attribute
}
return errors;
}
I would like to change the input attribute (input="/jsp/test/testStruts.jsp")in struts-config.xml dynamically so that I can forward to a specified page when there is an error.
Thanks in advance!
Jack

In the input attribute of the action tag instead of the jsp name, use an action mapping name and hence when u call mapping.getInputForward(), the action class is called where you can write code to send to any desired page e.g.:
<!-- Update a Users Professional Profile Information -->
<action path="/updateprofprofile"
input="/returnUpdateControl.do"
type="com.registration.action.ProfileAction"
parameter="method"
name="RegisterForm"
scope="session"
validate="true">
<forward name="failure" path="/index.jsp"/>
<forward name="thanks" path="/index-profile.jsp"/>
<forward name="refreshform" path="/returnUpdateControl.do"/>
</action>
<!-- Forward mapping control for profile updation -->
<action path="/returnUpdateControl"
type="com.registration.action.UpdateControlAction"
name="RegisterForm"
scope="session">
<forward name="usmdp" path="/usmdprofile.jsp"/>
<forward name="nursep" path="/nursesprofile.jsp"/>
<forward name="pharmacistp" path="/pharmacistprofile.jsp"/>
<forward name="ohcpp" path="/healthcareprovider-profile.jsp"/>
<forward name="healthadminp" path="/healthadmin-profile.jsp"/>
<forward name="physicianasstp" path="/paprofile.jsp"/>
<forward name="medstudentp" path="/medstudents-profile.jsp"/>
<forward name="intlmdp" path="/intl-md-profile.jsp"/>
<forward name="basic-profile" path="/getprofile.do?method=getBasicProfileFromId"/>
<forward name="error" path="/error.jsp"/>
</action>
// Inside ActionForm
public ActionErrors validateChangePassword(ActionMapping mapping, HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (true) {
errors.add("test", new ActionError("id_not_match");
// want to chnage the input attribute
}
return errors;
}

//Inside UpdateControlAction class which is a simple action class
ActionErrors errors = form.validate(mapping, request);
if(errors != null && errors.size() > 0){
//go to the input page mapping
}else{
//send to some other place
}
