Can not get error message to display on the same page
Hi,
I am trying to write a logon page as discribed on the struts-example, but finding
some problem with my logon.jsp when ActionLogon.java trys to return ActionErrors
or ActionMessages back to the original page, the logon.jsp. I am using Struts1.1
+ jboss-3.2.1_tomcat-4.1.24. I tried two ways to display the errors by using the
htlm:errors/ tag and without the tag. Can someone tell me what is going on.
Thank you in advance,
Kam Lung Leung
Below is the tested condictions for both situations:
The first part which is without the html:errors/ on the logon page and I only
had the code listed
below in the logon.jsp.
logic:messagesPresent
There were errors
font color='red'
html:messages id=validatorMsgs message=true
bean:write name=validatorMsgs/
/html:messages
/font
/logic:messagesPresent
I tested the following conditions:
1) userName == empty string, and password == empty string (invalid format case)
I got the popup window saying that User Name is required and Password is
required.
2) userName == hohoho and password == empty string (invalid format case)
I got the popup window saying that Password is required.
3) userName == hohoho, and password == ho (invalid format case)
I got no popup window, but instead the error massage was on the same logon page
saying There were errors. I am expecting a popup window with an error message
saying that password can not be less then 6 characters.
4) userName == hohoho, and password == hohoho (valid format case, but wrong
password)
I got either popup window nor error message on the logon page. I am especting
an error message as Invalid Password for this user on the logon page.
The second part which is with the html:errors/ on the logon page and I had the
code listed
below in the logon.jsp.
html:errors/
logic:messagesPresent

how to retrieve property values from previous forms/jsp pages
Hi, I need to retrieve property values from previous pages that were inputted by the user. For example; I have the following pages, actions and forms. firstPage.jsp firstAction.java firstForm.java secondPage.jsp secondAction.java secondForm.java finalPage.jsp finalAction.java finalForm.java In the finalAction class I need to retrieve property values that were filled in from the firstPage.jsp and the secondPage.jsp. Beside setting the scope of each form to session in the action mapping what else do I need to do so that I may retrieve those values? Any suggestion? Thank you in advance.

RE: how to retrieve property values from previous forms/jsp pages
Thank David,
The second option may not work for me because the secondPage.jsp will be further
extends to hotel.secondPage.jsp, car.secondPage.jsp and so on. The purpose of the
finalPage.jsp is to echo all values that were inputted from either the hotel
group(firstpage.jsp and the hotel.secondPage.jsp), or the card group
(firstpage.jsp and the car.secondPage.jsp). Then the user have the option to
either submitted or goes back to the firstPage.jsp. Thus I should not combine
the hotel.secondPageForm.java and car.secondPageForm.java into the
firstPageForm.java (that becomes combinedPagesForm.java). This will make the
combinedPagesForm.java too difficult to maintains in the future. The third option
looks more fit into my situation? How do i put the action's bean in the session
scope? Do you mean setting the scope to session in the action mapping. I thought
the scope setting was for the form bean. Can you give a simple code example?
How do I retrieve the property values of firstForms in my execute method of the
hotel.secondAction.java?
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
hotel.secondForm inputForm = (hotel.secondForm) form;
// retrieve all property values
//Now what to do to get the firstForm from here??
} //end execute
May be I need to use the request.setAttribute to setup a DAO object in the
firstAction.java and retrieve the DAO object from within the execute method of
the hotel.secondAction.java by using the request.getAttribute method? Can this be
done?
Thank you in advance,
Kam Lung Leung

One approach is to use hidden variables to ensure all fields are in every

Another approach is to have each action use the same form in session scope
so all fields are retained between POSTs (just remember to
getSession().removeAttribute(NAME) when you're done with it to free up
memory.
A third approach is to put each action's bean in the session scope similar
to the previous paragraph. Again, remember to remove the session beans when
you're finished with them to keep your memory usage down.
I prefer the 2nd approach: one bean in session scoped shared by multiple
actions.

Kam,
You can force a bean into the session scope by setting 'scope=session' in
the action mapping action.../ (or action.../action). To retrieve it,
you can do something like this:
HotelBean hotel = (HotelBean) request.getSession().getAttribute(hotel);
CarBean auto = (CarBean) request.getSession().getAttribute(car);
Then, when you're done with them in the final page, you can remove them (or
let them expire with the session, but I recommend removing beans when they
are no longer needed)
request.getSession().removeAttribute(car);
request.getSession().removeAttribute(hotel);
More details can be found on the Java ServLet Spec available on the net such
as on the Tomcat 4.1 site:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/servletapi/javax/servlet/htt
p/HttpSession.html
You can also set the cookie to last longer (see the interval set/get
functions) so sessions last longer than 30 minutes (Tomcat a default, I
think).

David

Re: Please Help!!! A Validation Rule Fail On A Second-Page Causes A Blank Page To Show Up
Hi Ted, Thank you for your time in helping me out. After your email message I take a hard look at the jsp file and can not find what was wrong with it. The secondPage.jsp is almost the same as the firstPage.jsp. When I move all the code from the secondPage.jsp to the firstPage.jsp the validation process went fine. All fields are validated by the validator. I have given up the hope to create a multipage form for now. And by the way I have purchased the Struts In Actions book along with other three books on the same subject. But there was not must information on multipage form. Do you have any suggestion on book that I may find some complete example on multi page form. To answers your your question about why do I reset all input fields to its original state when the getPage() is equal to 2 is that I only have two pages,firstPage.jsp and secondPage.jsp, each page would set the page number to 0 and 1 correspondingly. I set the page to 2 in the action class when the secondPage.jsp was executed. Then I call the form's reset method to clear all the fields before the control goes back to the firstPage.jsp. I guest you are right about removing the form bean should be good enough to remove all attributes in form for both pages. Thank again.

Sometimes the page doesn't render because of errors in the HTML, which might only be exposed when the page is trying to display error messages. I'm not sure why you would reset everything if getPage() is equal to 2. The usual approach is to allow the properties to accumulate, until the end of the workflow, and then dispose of the (session-scoped ActionForm altogether. Generally, the only thing you ever need to reset is a checkbox to false on a session-scope ActionForm. -Ted. Hi, I have been looking at this problem for the last four days and can't figure out.

Please Help!!! A Validation Rule Fail On A Second-Page Causes A Blank Page To Show Up

validation errors on multi pages form
Hi, I have an application that required workflow like jsp pages. I created an action name CreateUserAccountAction that extends the DispatchAction and a form MultiCreateUserAccountForm that extends the ValidatorForm. The reset method of the MultiCreateUserAccountForm will clear all attributes under the current session when the getPage() is equal to 2. The CreateUserAccountAction has two methods that are similar to the execute method that are named createUserAccountActionOne and createUserAccountActionTwo. The createUserAccountActionOne method calls the MultiCreateUserAccountForm.validate() method to validate the user input fields of the firstPage.jsp. Second, it calls the setPage() method with 1 as its input parameter. Finally, it calls the MultiCreateUserAccountForm.setMethodToDispatch() with createUserAccountActionTwo as the input parameter. The createUserAccountActionTwo method calls the MultiCreateUserAccountForm.validate() method to validate the user input fields of the secondPage.jsp. Secondly, it remove the obsolete form bean with session.removeAttribute(mapping.getAttribute()). Thirdly, it calls the setPage() method with 2 as its input parameter. Finally, it calls the reset() method to clear all attributes under the current session. If there is a required field that is missing (leaved out) on the firstPage.jsp when the submit button is pressed. A new dialog box poped up on the screen with the validation message from the resource property file. When every field is validated the controll is forwarded to the secondPage.jsp. If there is a required field that is missing (leaved out) on the secondPage.jsp when the submit button is pressed. A blank page is showed on the windown without a new dialog box shows up on the screen. The server.log indicates an error occurred and returns to the same page (secondPage.jsp). To fixed this problem, I pressed the back page button of the browser and correctly filled in all missing fields. When every field on the second page is filled correctly according to the validation rules then the controll is correctly forwarded to the firstPage.jsp. My question is following: Why don't I get a pop up dialog box with error messages ? Why the secondPage.jsp did not get executed? Why do I get a black screen? ** This are action mapping *** action path=/multiCreateUserAccountFirstSubmit type=com.wlwa.CreateUserAccountAction name=multiCreateUserAccountForm scope=session validate=true parameter=methodToDispatch input=/CreateUserAccountLink.jsp forward name=success path=/CreateUserAccountSecondLink.jsp / /action action path=/multiCreateUserAccountSecondSubmit type=com.wlwa.CreateUserAccountAction name=multiCreateUserAccountForm scope=session validate=true parameter=methodToDispatch input=/CreateUserAccountSecondLink.jsp forward name=success path=/CreateUserAccountLink.jsp / /action Kam Lung Leung Kam Lung Leung System Architect Wireless Web Access Inc.
