reset method causes values not displaying
Hi
Can someone point out why this do not work, or why this work?
What this does, get a Actionform, set a value in it, add the ActionForm
into an Vector, set the Vector into Session.
Strangely the new ActionForm is not displayed in the JSP returned by
ActionForward. It only appears if the ActionForm reset is not called
before returning the method.
How can the reset method affect my codes?
and yes, the values was printed out before returning and all the values
are there..
Why is that so?
Thanks
Sebastian Ho

public ActionForward addColumn(ActionMapping mapping, ActionForm form,

//GET VECTOR FROM SESSION

Re: reset method causes values not displaying
Now this is a Java question, if XXX newForm = (XXX) form resulted in form and newForm having the same memory space? How do I really make a duplicate copy with different memory space (beside using new, or is new the only solution)?

Thanks Sebastian Ho - snip //RESET FORM //form.reset(mapping, request); Since all Java calls with objects in them are call-by-reference you are actualling calling reset on the object you've just added to your Vector. I don't know how your reset method is implemented of course, but I would presume that all the values are reset to default values when you call reset. If you want to preseve the values you've would have to make a copy of the form object and then add the copy to the vector... Don't know if this is what you meant, but this is how I understand it :-) Enjoy...

Re: need advice: session scoped objects or session scoped ActionForm ?
For every calling page, use a new mapping in yr struts-config. I assume u mean setting the action as session scope in yr config? They are the same I think, the important thing is to keep it to one solution and use it thoughout the application. Else it will be confusing and hard to debug as yr application grows. Sebastian On Wed, 2004-10-13 at 08:59, lixin chu wrote: Hi, I am seeking your expert advice: I have a simple page with Done and Cancel buttons. If any of these buttons are clicked, I suppose to go back to the calling page - there are a few pages that will come to this page. It is a simple workflow type of thing. So I need to know the retutn URL, pls some other stuff. The question is, where do I keep the return URL which is passed in as request attribute ? Since the current page has some other buttons not just Done and Cancel, I use LookupDispatchAction, that means I have to keep the return URL in the session. Which one is a better solution: keeping it in the session scoped ActionForm or request.getSession().setAttribute ? It is easier to manage the return URL if put into ActionForm becuase it is isolated, no naming conflict-bur ActionForm is for UI components only; otherwise, I need to keep it in the session using a name reference something like myAction_returnURL, and also I need to handle the cleaning - it is still possible that the sting is kept in the session until the session is closed if the user does not click Done or Cancel. any best practice ? may be the best is to avoid using session scope objects but I just can not think of a way out for my use case. thanks in advance LX __ Do You Yahoo!?

Hi, Sebastian.
It looks like the call to new FileForm() throws an exception.
Have a look at your Tomcat logfiles. There might be more information about the JSP
compiler failing.
If that is not the case, check that the class exists (class name/package name).
If it is the first instantiation in your application, it might be a class loading
problem. Maybe another class FileForm relies on cannot be found.
If it is a second, ... instantiation check what code runs in the default constructor.
This is what I'd go for.

I noticed that the validate method in ActionForm is not called. The
exception occurred during the bean population.
Hope someone can help.

Re: jasper exception
I got it working although I don't know why it behaves that way.. In my JSP, I have a /html:frame somewhere in between the lines. Once I remove it, the exception went away.

Re: bean missing after validation
Tried changing it to session scpope. Guess wat, I hit into another
problem. Because the values are in session scope, whenever there's
validation errors, the values entered by user previously was reset to
whats set in session!
Guess have to continue reading to find a workaround.. If only struts
does this for me..

But there is nothing wrong with using the standard html hidden input as

Using Session scope is one way, but not the only way, to solve your
problem. (Don't be afraid of it though). This is not an easy problem
despite the simplicity of the concept of scope. Keep reading!

RE: bean missing after validation
Ok I resolved it and I think this is the best way at least for now.
In my ActionForm, set the attribute back in request if there's error :
if(errors != null) {
ActionForm form = new ActionForm();
form.set
form.set
request.setAttribute(user, form);
}

Problem forwarding with Servlet and Struts
Hi I don't know this is a struts or servlet or my problem. I am implementing servlet filter. I can access 'index.do' fine before implementing the filter. After I implemented the filter, a forward to 'index.do' gives me a blank page. This is the only statement in my doFilter() method. this.myFilterConfig.getServletContext().getRequestDispatcher(/index.do).forward(request, response); Anyone experience somethign similar?

Multiple button with same value using same Action class
Hi
I have been using LookupDispatchActin for a while and everything works
fine until..
I reuse the same Action class for a couple of JSPs. Some of the JSP has
the button Cancel in them. Because they are in different JSP, the
forwarded JSP will be different when Cancel is selected.
In the getKeyMethodMap() method, I have a few keys which maps to
'Cancel' in my applicationresources.properties. And each of them will
map to a different method.
Problem is they are using the same 'Cancel' value with parameter
'action'. Because of the way LookupDispatchAction works, the first key
that map will be used and the corresponding method called.
Can I make it maps to different methods?
How do I resolve this? I am using Struts 1.1.
To illustrate
In X.jsp :
html:cancel property=action value=Cancel
bean:message key=button.cancelforgotpassword/
/html:cancel
In Y.jsp :
html:cancel property=action value=Cancel
bean:message key=button.cancelsign/
/html:cancel
In properties :
button.cancelforgotpassword = Cancel
button.cancelsignup = Cancel
In Action :
protected Map getKeyMethodMap()
{
Map map = new HashMap();
map.put(button.cancelsignup, cancelSignup);
map.put(button.cancelforgotpassword, cancelForgotPassword);
return map;
}

Re: Frame problem using Struts
Sorry but I don't understand where is the 'dynamic targetting'. From the
example, don't we need to hard code the setDynamicTarget(XX) in the JSP?
But I won't know the taget to set at that time..

By default, the target will be '_self' but depending on the clicked

or any opended window.
Your Action will forward your path (succes, failure,...) to the
corresponding target window.

function setDynamicTarget(target) {
document.forms[0].target = target;
}
function SubmitForm(object) {
object.form.submit();

conversion from button to link
Hi I replaced the following struts tags for a button with one that display a link. The Action uses LookupDispatchAction. That explains the need for my message key in it. /html:form html:form action=MainMenu.do target=basefrm html:submit property=action value=Create Project bean:message key=button.createproject/ /html:submit This is my replacement codes for a link. a href=MainMenu.do?action=Create Project target=basefrmCreate Project/a I am surprised that this works!

request in actionform validate()
Hi A quick question.. I should be able to get request attributes from the request parameter in validate right? In my case, there is nothing in my request but in my JSP I already have the hidden fields. And what about request attributes in the same JSP, it seems like they were gone if validation fails and returns to the same JSP. Shouldn't struts keep them somewhere in case validate fails and the JSP needs to be displayed again? Any reasons what might go wrong?

Questions on logging
Hi I am in the stage of implementing logging in my struts application. I have been reading online but have some questions unanswered. 1. Action class should be thread-safe. Therefore no static variable, I should just use a non-static variable to hold my logger? 2. In a multi-user web application, how can I keep logs from the same class (same execution thread or same user request) stays together? I envision them to be all messy in the log file when there's multiple user requesting for the same action class. 3. About the thread safe issue with Actin class, that doesn't apply to the other classes that action execute right? Those are treated as normal java files.

Re: illegalargumentexception thrown
I resolved it although I don't know when the value changed. I added / before the 'input' in my action-mappings. Can't remember was it there all along because I didn't take note and it works for the past few days and I didn't edit the struts-config.

Possible to change input path in actionForm validate?
Hi Is it possible to change the input path that validate() displays if there are errors in the validation? I try using mapping.setInput() but it returns java.lang.IllegalStateException: Configuration is froze. Reason for this is I am using the same Action for different JSP, therefore the validation errors need to be displayed in the respective JSP, and not the input path specified in actino-mappings.

ActionForm and Transfer Object
Hi People have been telling me that ActionForm should not be dependent on your TO. Simple because actionForm is for presentation and TO for your business requirement. Sounds logical and right way to go. Now that I started developing using struts, it is actually not that simple. Say I retrieve a TO from database and convert it into a actionForm for display. In this case I have 4 fields for my actionForm but 10 in my TO. (6 are not needed for display). A user updates the 4 fields and the action convert those into TO. In this case, the other 6 fields will be reset to null(or empty) in my database! To prevent this, I actually need to use hidden fields in my JSP or some other ugly solutions in my Action class. They are still dependent on each others afterall. Is there a solution to this or I am missing something here?

Re: duplication of codes in different Action class
I am already using DispatchAction. I didn't use the scope in my action-mapping. Instead I use session.setAttribute in my Action. The codes to update the actionform is in action1. But I need to update the same form in action2. One way is to duplicate the same codes in both action. Or the common update codes can be executed before a JSP is loaded. The latter will prevent duplicate codes. sebastian On Wed, 2004-08-25 at 14:26, Rick Reumann wrote: Sebastian Ho wrote: Hi Scenario : 1. User submits form in JSP1 which Action1 saves to database. 2.

How do I make JSP1 to get values from database BEFORE JSP1 displays and set them into session? I suppose I have to do this in Action1 but for the first submission of form1, Action1 is not called yet by JSP1. From my analysis, there will be situation where there will be multiple input sources into a particular JSP. That means I need to have my 'update from database and set in session' codes in all the Action classes that forwards to JSP1? In another words, how do I call the update method in Action1 from Action2 before forwarding to the JSP which display my updated data. This is duplication of codes and inefficient to me. There must be a better way to do this in Struts. My question might be confusing..I am trying my best. Tell me if its unclear. It's unclear:) Some of you terminology might just be wrong which is making it more confusing. For example in step 2 above, are you setting the form in session scope yourself? You normally don't need, or want, to manually do this. You delcare the scope of your form in your action mapping. I think what you are wondering about is How do you get your form populate for your JSP so that that user can alter it? (I could be wrong here)... anyway I like to use a DispatchAction which has several methods in it... setUp, Update, etc. So your first call when the user clicks on a link would call the setUp method and there you would make sure your form is populated with the data it needs and you forward to your JSP. As a side note, you do not need to be using Session scope for this. Do you have a particular reason why you need to be using Session scope for your form (many times you do, but I'm guessing in this case you don't and you are using the Session because you are not understanding the flow of how Struts operates). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ActionForm and Transfer Object
I don't really like the first solution. Second solution sounds promising but there's an extra call. But thats still better than the first solution or using hidden fields in JSP. I thought of putting the TO in session as well to prevent another DB call. But that will make everything very confusing and complex on the web tier.. Still looking for an ideal solution. This problem is quite common I think, someone here must have a best practices for this so I am waiting for one.. Thanks Rick.

They are still dependent on each others afterall. You can handle this several ways... For example, one solution is you create a TransferObject that refers to only the fields you care about - in this case the 4 fields you mentioned. So your call to the business layer would return that TransferObject and you could then convert that easily to your form (using BeanUtils). Then going back the other way your business layer would take as an arguemnt the same type of TransferObject. I actually don't prefer the above, though, because say later on you decide you want to add another field to your form now your backend has to worry about handling a new object with different fields. I think the best solution is to simply make another call to get back the initial TO from the db, then simply use BeanUtils to populate that TO with the form fields. It will only set the fields in which it has the same names for so your other data will be fine. So it looks like... TransferObject to = BackendEnd.getMyTransferObject(..); MyForm myForm = (MyForm)form; BeanUtils.copyProperties( to, myForm); BackEnd.doUpdate( to ); Pretty simple I think. Just make sure your ActionForm doesn't contain properties that you don't care about editing otherwise it will over-write the TO properties. If the JSP form is going to be very dyanmic, as in it will sometimes have some properties and sometimes have others, then you will have to use more complex 'tricks' such as using hidden variables.. or I'd just prefer to manually set the TO fields in the Action. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You normally keep related action tasks together in one DispatchAction. Maybe I need to refactor my codes.

strange request scope behaviour
hi
I am having this strange behavior that I don't understand.
I keep having 'experiments' in my request scope when I don't think I put
that in.
I only paste the important codes here because they are too big.

In my action class :
---
if(request.getAttribute(experiments) == null)
{
System.out.println(experiments is null);
}
return mapping.findForward(success);
---
Above prints out 'experiments is null' so it is not in the scope
struts-config
---
action path=/CreateExperiment forward=/CreateExperiment.jsp/
action name=projectForm path=/NewProject input=CreateProject.jsp
scope=request

/logic:present
logic:present name=experiments scope=session

The JSP prints out error.project.title! when there should not be in the

I don't see it here, but here are the things to look for:
1) Somewhere in the action/form/jsp request.setAttribute(expirements, blah);
2) Forward forward name=blah path=/yourPath?experiments=/
3) A link that sets experiments.
It would shock me to find out that the word experiments is anywhere in the struts

Sebastian Ho Which method are you using in your Action classes? If it is the perform() method from Struts 1.0, there is no throws clause there, so you will definite get compile errors if you try to throw one. Change over to the execute() method (and be sure you're using Struts 1.1, of course), and you will be able to throw any exception that you like.

different inputs in struts-config
hi I used the same actionform for a few JSP pages, which I guess is good practice. The problem occurs when I add in validation in my ActionForm. Because in the struts-config, only one input is specified for every Action. Therefore, whenever validation fails and struts display the error messages, struts prints it in the JSP given in input. Ideally, struts should forward and prints out the error messages in the JSP that calls the ActionForm. I tried adding in multiple action mapping in my struts-config with identical settings except input, which I hope struts will be smart enough to decide which mapping to use. Unfortuntely, it doesn't. I have read online that this strategy is quite popular. Therefore I am sure there is a solution to this problem. How do I forward the ActionError to the correct JSP instead of the one in input?

Yes, you can reuse your actionform for multiple action mappings, but are your action mappings really identical except for the input? If I understand what you are trying to do, it sounds like you should have: Action1 specifies ActionForm1 and input JSP1 and forwards to JSP1. JSP1 probably then submits to Action2. Action2 specifies ActionForm1 and input JSP2 and forwards to JSP2. JSP2 probably then submits to Action3. Action3 specifies ActionForm1 and input JSP3 and forwards to JSP3. All of them ues the same action Action because I am using LookupDispatchAction. So the struts-config ideally should be (which doesn't work) : Action1 specifies ActionFrom1 and input JSP1. Action1 specifies ActionForm1 and input JSP2. Action1 specifies ActionForm1 and input JSP3. How do I achieve this effect? Is that about right? In this case, Validator should work fine. Hth, Susan Bradeen I have read online that this strategy is quite popular. Therefore I am sure there is a solution to this problem.

Re: how not to use actionform and pass things around
Guess you are right in a way. But I don't know how to solve this scenario using struts.. Say I have three JSP (JSP1, JSP2 and JSP3). JSP1 populates my actionform (AF1) and in my Action, I set it into my request (not using a session) so that it is available to JSP2. In JSP2, I have yet another ActionForm to populate. Here I just want to pass AF1, which is available in the current page (JSP2) to the next JSP3. Therefore I will have two actionforms in JSP2, the new actionform and AF1 in a single form. Now, how do I pass both actionforms to the Action class of JSP2? I might be asking something stupid here, but this is what I want to achieve and I have no idea how to do it.

Disable validate in actionForm
hi I have an validate method in my actionform and everything works fine. I added a 'Back' button in my webpage, and therefore validation is not necessary if the 'Back' button is clicked. Validation should occurs only if 'Next' is selected. How do I stop struts from calling validate() is 'Back' is selected? Note : Both buttons are in the same form.

RE: Disable validate in actionForm
Hi
I think my situtation is kinda unique..
I have three buttons in a single form and my Action extends
LookupDispatchAction.
In my ExperimentForm (actionform), how do I disable validate if 'back'
is clicked?
struts-config.xml
--
action name=experimentForm path=/NewExperiment
input=CreateExperiment.jsp parameter=action scope=request
type=sg.edu.astar.flamingo.web.proteomics.view.NewExperimentAction
forward name=addexperiment path=/CreateExperiment.do/
forward name=next path=/CreateProjectSummary.do/
forward name=back path=/CreateProject.do/
/action
CreateExperiment.jsp
-
html:submit property=action value=Back
bean:message key=button.back/
/html:submit
/html:submit
html:submit property=action value=Create Experiment
bean:message key=button.createexperiment/
/html:submit
html:submit property=action value=Next
bean:message key=button.next/
/html:submit
applicationresources.properties
button.createexperiment=Create Experiment
button.next=Next
button.back=Back
NewExperimentAction.java
---
public class NewExperimentAction extends LookupDispatchAction
{
/**
* This is the main action called from the Struts framework.
* @param mapping The ActionMapping used to select this instance.
* @param form The optional ActionForm bean for this request.

// public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException
//{
// return mapping.findForward(success);
// }
protected Map getKeyMethodMap()
{
Map map = new HashMap();
map.put(button.createexperiment, createExperiment);
map.put(button.next, next);
map.put(button.back, back);
return map;
}
public ActionForward next(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException
{
System.out.println(next());
return mapping.findForward(next);
}
public ActionForward back(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException
{
System.out.println(back());
return mapping.findForward(back);
}
public ActionForward createExperiment(ActionMapping mapping,
ActionForm form, HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException
{
ExperimentForm experiment = (ExperimentForm) form;
HttpSession session = request.getSession();
Vector experiments = (Vector) session.getAttribute(experiments);
experiments.add(experiment);
return mapping.findForward(addexperiment);
}
}

Map it to a different actionMapping and set validate=fasle;
ie the submit and back button should have a different actionmapping

hi
I have an validate method in my actionform and everything works fine. I
added a 'Back' button in my webpage, and therefore validation is not
necessary if the 'Back' button is clicked. Validation should occurs only
if 'Next' is selected.
How do I stop struts from calling validate() is 'Back' is selected?
Note : Both buttons are in the same form.
Thanks
Sebastian

RE: Disable validate in actionForm
Tried javascript and it works fine. The reasons I try not to use javascript : 1. since struts is used, i thought all control should be visible in the controller and not as javascripts in the JSP. 2. User might turn off javascript. sebastian ho On Tue, 2004-08-17 at 15:57, Aru wrote: Sebestian, Where does control go when u click Back button?

RE: Disable validate in actionForm
Thanks Richard I fixed the Back problem using javascript (using javascript history.back()). Although it is resolved, I am still very much interested in the struts solution without using javascript. sebastian On Tue, 2004-08-17 at 18:46, Richard Aukland wrote: Sebastien, I use this technique, it works but i dont know if it is 'good practice' 1. Change your 'back' button from a submit to a cancel button (thereby avoiding validation) 2. Set the action of the button to 'previous' using javascript . 3. pick up the 'previous' in a DispatchAction class and forward to appropriate place. Note that if you use LookUpDispatchAction i think you may be able to avoid the javascript. regards Richard Richard Aukland 49 Ravensmere, Beccles, Suffolk, UK.

RE: Disable validate in actionForm
I suppose this is how I do it?
html:submit property=action value=Create Experiment
bean:message key=button.createexperiment/
html:hidden property=selection
value=createexperiment /
/html:submit
And in my ActionForm :
if(getSelection().equals(createexperiment)) {
//validate
}
But getSelection returns me a null and I don't know why..

what about checking for the back property in your
validate method (as i wrote few mails ago)?
according to your description of CreateExperiment.jsp just
change the proposed code to:
8 snip -
public ActionErrors validate ( ... ) {
if (! back.equals (getAction ()) ) {
super.validate ( ... );
// another validations if needed
}
}
8 snip -
i still suppose you have defined property action
in your form bean.

Re: Recommend Struts Plugins for Eclipse?
I tried JDeveloper 10g last week. It has visual view of your struts flow, JSP editing, struts-config editing, etc. Works great! sebastian BII On Sun, 2004-06-27 at 22:22, Bryce Fischer wrote: Struts Studio. The best...

generators for struts
hi i am starting a new project which involves struts and i am completely new to it. The IDE i am familar with is Netbeans. What tool does fellow developers used for struts? I downloaded struts console but looks like it allow me to edit/manage struts configuration file in netbeans only. Is there any xdoclet like tool that make code generation easiler? If possible please provide plugin/tool for netbeans instead of eclipse. I can't find a plugin for running jboss in netbeans too. Any references?
