ActionForm LifeCycle (Maybe a bug in Struts)
Hi All,
I was wondering if anyone knew what the lifecycle of an ActionForm is?
The reason I ask is in regards to the display of variables with a .
I have noticed that the values displayed within a are values after a
reset() method has been called,
and not after a validate method is called. Can anyone tell me the reason for this, as
I seem to think this is a bug
within the Struts framework.
An example follows as to what I am talking about (based upon the following ActionForm):
// Example ActionForm
public class MyActionForm extends ActionForm {
private String maximumDocuments = "3";
...// More variables
public MyActionForm() {
super();
System.out.println("Constructor called");
}
public void setMaximumDocuments(String maximumDocuments) {
this.maximumDocuments = maximumDocuments;
}
public String getMaximumDocuments() {
return maximumDocuments;
}
...// More get/set methods
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest
httpServletRequest) {
ActionErrors errors = new ActionErrors();
System.out.println("validate called");
System.out.println("before processing maximumDocuments: " + maximumDocuments);
if(maximumDocuments == null) {
maximumDocuments = "50";// The supposed default value (if no value
entered)
}
System.out.println("after processing maximumDocuments: " + maximumDocuments);
...// Say an error has been returned
return errors;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
System.out.println("reset called");
System.out.println("before processing maximumDocuments: " +
this.maximumDocuments);
this.maximumDocuments = "50";
System.out.println("after processign maximumDocuments: " +
this.maximumDocuments);
}
}
SCENARIOS:
LIFECYCLE 1: From a previous page to a form which uses this ActionForm
The following output gets displayed:
Constructor called
reset called
before processing maximumDocuments: 3
after processing maximumDocuments: 50
RESULT: Here the value displayed in the form is 50 for maximumDocuments (Correct)
--
LIFECYCLE 2: If an error occurs within the ActionForm (and the value 1 has been
entered for maximumDocuments)
The following output gets displayed:
Constructor called
reset called
before processing maximumDocuments: 3
after processing maximumDocuments: 50
validate called
before processing maximumDocuments: 1
after processing maximumDocuments: 1
RESULT: Here the value displayed in the form is 50 for maximumDocuments(Incorrect
as it should be 1)

Can anyone please tell me why this is happening, and how to correct this problem.

Problem redisplaying data user has entered within a form
Hi
All,
I am currently
experiencing a problem in regards to redisplaying form data a user has entered
within a form.
I am experiencing
this problem both from ActionForm and LookupDispatchAction classes in a
major project.
As a consequence I
decided to
write a very small login application to see if I could solve this
problem.
The
login application will display a user login application screen. If a user
tries to login, and does so successfully a
welcome page is displayed. However if
not successful a informative message should appear, as well as what the user has
entered into the fields.
Unfortunately the
data the the user has enetered never gets repopulated in the form text fields
when login has been unsuccessful.
Has anyone got a
solution to this problem. Any help would be appreciated.
Cheers
Rodney
ps. NOTE: The first
screen the user sees comes directly from a JSP page (not from a redirect of a
Action class to a JSP page).

RE: Redisplaying of entered form fields
Hi Jan,
Thank you for responding to my email, most appreciative.
So from what I gathered from your response this is what I should do:
---
CHANGES TO CODE BASE
---
/* PART 1 Configuration File: */
/* PART 2 Class Changes: */
public class OrganisationNameSearchAction extends LookupDispatchAction {
protected java.util.Map getKeyMethodMap() {
Map map = new HashMap();
map.put("validateError", "validateError"); // CHANGE
map.put("button.next", "next");
return map;
}
// ADD METHOD
public ActionForward validateError(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
String target = "failure";
ActionErrors actionErrors = new ActionErrors();
try {
OrganisationNameSearchActionForm organisationNameSearchForm =
(OrganisationNameSearchActionForm)form;
String organisationName = organisationNameSearchForm.getOrganisationName();
String ACN = organisationNameSearchForm.getACN();
if((organisationName == null) || (organisationName.trim().equals(""))) {
errors.add("organisationName", new
ActionError("error.organisationName.required"));
}
if((ACN != null) && (!ACN.trim().equals(""))) {
try {
Integer.parseInt(ACN);
}
catch(NumberFormatException e) {
errors.add("ACN", new ActionError("error.ACN.format"));
}
}
}
catch(Exception e) {
target = "error";
}
finally {
// Save errors if needed and forward to the appropriate page to display
if(!actionErrors.isEmpty()) {
saveErrors(request, actionErrors);
}
return (ActionForward)mapping.findForward(target);
}
}
}
---
Now in your reply you stated "...in this method you then can initialize what you need".
Do I take it that is where I must store the variables the user has entered.
If so do I store the user input directly into the session object,
or do I store the user input indirecty into the session object via the ActionForm.
ie.
session.setAttribute("organisationName", organisationName);
session.setAttribute("ACN", ACN);
OR
session.setAttribute("ActionForm", actionForm); // has ACN and organisationName
Also within my JSP code do I just leave the code as is (as I am using the html struts
taglibs)
or do I change the JSP to redisplay the user input. Below is some JSP code I use.

Subject: Re: Redisplaying of entered form fields
Rodney,
I had similar problems with a DispatchAction. The problem is, when the
validation fails, it does not come into your action class; the good news is
that you can define an 'input' attribute in your actionmapping
(struts-config.xml) which will be used when your validation fails; I had put
a reference to a .jsp page, but you can also specify an action.
In my DispatchAction class, I have a method name validateError(...); you
then define the input attribute as
input="myAction.do?method=validateError"
myAction is an action mapping which maps to the same class.
in this method you then can initialize what you need.

Redisplaying of entered form fields
Hi All,
I have a problem redisplaying form fields a user enters within a html form.
I use the validate method to validate form entry fields through ActionForms.
and validate business logic in LookupDispatchAction classes.
Has anyone experienced this problem, and is there any solution to this
matter.
Cheers
Rodney
CODE:
Below the code you see is part of an application I am building.
The problem here lies in the fact that in all cases,
field data does not get redisplayed within the form the user has entered data in.
eg. if you enter a invalid data within a numeric data field (this instance ACN)
then the ActionForm issues a error message gets issued (works)
but the ACN previously entered does not get redisplayed in the form.
eg. if you enter a valid ACN or Organisation Name within the fields to do searches,
and no data is applicable to the search criteria entered a error message gets
issued (works)
but no ACN/Organisation Name gets redisplayed in the form where the data was
entered.
Part 1: Sample Configuration (struts-config.xml)
PART 2: Application form code (validation and reset methods)
public class OrganisationNameSearchActionForm extends ActionForm {
// Get and Set methods
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest
httpServletRequest) {
ActionErrors errors = new ActionErrors();
if(method.equals("Next")) {
if((organisationName == null) || (organisationName.trim().equals(""))) {
errors.add("organisationName", new
ActionError("error.organisationName.required"));
}
if((ACN != null) && (!ACN.trim().equals(""))) {
try {
Integer.parseInt(ACN);
}
catch(NumberFormatException e) {
errors.add("ACN", new ActionError("error.ACN.format"));
}
}
}
return errors;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
this.method = null;
this.organisationName = null;
this.ACN = null;
}
}
Part 3: Action Code (Sample)
public class OrganisationNameSearchAction extends LookupDispatchAction {
protected java.util.Map getKeyMethodMap() {
Map map = new HashMap();
map.put("button.next", "next");
return map;
}
public ActionForward next(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
boolean error = false;
boolean failure = false;
String target = "next";
ActionErrors actionErrors = new ActionErrors();
try {
HttpSession session = request.getSession(false);
if(session != null) {
OrganisationNameSearchMessageDTO organisationNameSearchResult =

if(organisationNameSearchResult == null) {
error = true;

Struts Error Handling Problem
Hi All, I am currently using the Struts framework to develop a wizard application. When using the Struts framework I notice that form data does not get re-displayed after issuing ActionErrors. Is there any reason for this?

RE: best way to build a wizard
Well with the LookupDispatchAction class you can name a parameter to be used
to determine what method to execute. In this instance The "Next" and "Previous"
buttons would point to a same parameter to be used.
eg.
Now the code in the LookupDispatchAction class would look something like this:
public class MyAction extends LookupDispatchAction {
protected java.util.Map getKeyMethodMap() {
Map map = new HashMap();
map.put("button.previous", "previous");
map.put("button.next", "next");
return map;
}
public ActionForward previous(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
String target = "previous";
...
return (ActionForward)mapping.findForward(target);
}
public ActionForward next(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
String target = "next";
...
return (ActionForward)mapping.findForward(target);
}
So both submit buttons would go to the next page, and within that action you would
transfer control to the previous or next pages.
Cheers
Rodney

I'm not sure that really solves my problem. What do I put as the
"input" for this action? I can't use the same action; whatever
attribute I used to indicate that I want to move to the next page would
still be in the system, so validation failures would bring me to the
next page rather than the same page.
I'm pondering an approach with two actions, a "next page" action which
has a "same page" action as its input.

Check out the lookupDispatchAction classes. These classes were designed specifically for Actions which require more than one execute method (in this instance a method for back and next).

RE: How to pass a value object to another action
ActionForms sole purpose i believe is to capture information the user has entered within a web page. Hence we have in Struts the MVC 2 model, whereby the presntation layer is represented by JSP/velocity pages, ActionForm classes used to capture information the user has entered within the preentation pages, and Action classes to process business logic. Now in regards to preparing information for you to render within multiple presentation pages, information should be stored in session objects. Hence in your case, if you need to present information to the Action B class from Action A, store this in a session object. Also have a storage place in the ActionForm class so that Action B can retrieve the information in an appropriate manner.

Struts Error Handling Problem
I am currently experiencing a problem with the Struts error handling framework.
I am trying to use the error handling framework from ActionForm and
LookupDispatchAction classes.
The problem I have is in regards to display of error messages. I have found
that error messages are being displayed correctly using the tag
from a ActionForm validate method, but are not being displayed using the
LookupDispatchAction methods. Please see below:
ActionForm
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest
httpServletRequest) {
ActionErrors errors = new ActionErrors();
errors.add("field", new ActionError("messageKey"));
return errors;
}
LookupDispatchAction
public ActionForward next(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
...
ActionErrors errors = new ActionErrors();
errors.add("field", new ActionError("messageKey"));
if(!errors.isEmpty()) {
saveErrors(request, errors);
}
return (ActionForward)mapping.findForward(target);
}
Could someone please tell me why this is so. I would be most interested if
anyone could provide a solution for this.
NOTE:
I am using the Struts version 1.1 release with tomcat version 4.1.24

Instead isn't it a better approach to put the authorization policy related rules in a database ? Please give you view points.
