Re: how to implement such an action?
Alex:
ok, let me state the problem as i understand it:
ActionA --> page1.jsp -->ActionB
if (success in ActionB) forward to success.jsp
else forward to ActionA.
Your question is how to get the "if failure" part working.
If my understanding of your problem is wrong, please write back and tell us where
I'm wrong.
However, if this *is* the problem, here's how you can implement a solution using
hidden vars:
In page1.jsp, use a hidden var:
In ActionB.execute, if failure do the following:
String theAction = formBean.getTheAction();
ActionForward failureForward = new ActionForward();
failureForward.setName("failure);
failureForward.setPath(theAction);
log.debug("Redirecting to " + failureForward.getName() +": " +
failureForward.getPath());
return failureForward;

Re: how to implement such an action?
Alex: Here's an easy way to implement this: Have a hidden variable in each of your jsps which reflects the name of the jsp you are on and use that in your action class to prepare the forward (do you see what i'm saying..? I can elaborate if you'd like..) . You could also use something like request.getRequestURL() (I think this is right..look in the API to be sure..) if you don't want to use hidden variables..

Re: how to implement such an action?
Alex: Your initial page is just a jsp, right? So why would you not use your action mapping to say something like if "success then forward to newpage.jsp and if not forward to samePage.jsp"..? This will work unless you are using this refresh action in many pages..? In which case, you will have to "remember the page" - and that can be done - but if the simpler solution works, that may be best, especially since you say you are a newbie..:) Please ignore this note if you have already received emails about your question: our mail server has been *really* slow recently and I can see no replies to your question yet..

Re: how to use bean:define for this
Dean: Yes, I do see your problem and since (as i inderstand it) Struts tags work via reflection, it needs an instance of the class before you can use and then go ahead and use "allCountries" as usual later in your jsp.. I believe you can use it within struts tags with no problem.. Regards, Geeta "Dean A. Hoover" wrote: > > > > that's what I am trying to avoid...

Re: how to use bean:define for this
Dean:
Oh, Ok, I think i see what your issue is now (shouldn't have hit that earlier
"send" so fast..!) Ok, in the action before you forward to the jsp, populate
your countries variable. Then set your session variable (in your Action
class), say, session.setAttribute("countries", countries); (though i still
wonder about making this a session var.. anyway..).
In your jsp then you can simply say:
You should then be able to access the "allCountries" Collection further down
in your jsp..
Hope this helps,

Re: how to use bean:define for this
Dean: First, you need this "countries" Collection available in kind of an application-wide context, right? I mean there is no reason to "attach" this as a session variable since I imagine it would not change from user to user... Also such variables are best initialised/populated in a class (the model) rather than in a jsp, since jsps should just be used mainly for the view..

Re: porting to struts
Rajat: Markus is quite right.. however, for what it's worth, you may like to know we pretty much did exactly what you are suggesting: Relaese 2 of one of our bigger web applications was an extension (funcionality-wise) of Release 1. Relaese 1 was completely written with servlets/jsps and we chose to use Struts for Release 2. Also, as you mention below, access to the connection pool logic was written early on (therefore with a servlet). Relaese 2 thus was a combination of the old and the new and we have not seen any problems at all. In fact Release 3 is now ready (in a couple of weeks) to be moved into production - this has more Struts stuff - and testing has produced no issues at all which were related to the fcat of Struts and non-Struts code living togther. As far a we can see, it is a happy co-existance.. Which of course makes sense, since Struts is after all a glorified servlet, albeit a great one..:) Hope this helps and good luck with your new Struts venture!

Re: 1 request & 2 forms
I have never done this but i don't see why not. When you press your submit button on your jsp, an Action is called, right? You can do whatever you want in that execute method would be my guess. So if you feel like saving one form in session scope and another in in request attribute before you forward to your new page, i don't see why you shouldn't be able to.. Do you envision a problem?

Re: Extending Request Processor to append request parameter
Brad:
I looked at the API and noticed the RequestProcessor is a 1.1 feature.. Your
solution seems nice and clear! I only have one question for you though: How
do you "connect" the subclass of RequestProcessor that you wrote with the
struts ActionServlet..? Do you have to subclass the ACtionServlet too and
then join the dots there? How do you do that? There is a " processor" method
in ActionServlet which returns the processor..but I don't see a setProcessor
method..?
thanks for posting your solution: I learnt something new today..:)

Re: Extending Request Processor to append request parameter
Brad:
Here's one very simple way of achieving your objective, but I am quite
certain other people will have better ones, but since this is kind of a
cute problem, I want to offer this as well..:)
First write a simple "util" method (I always have a Util class in my apps
where I gather stuff which seems to belong nowhere else..). Anyways, write
a method with signature as follows:
private static String makeUnique(String)
which essentially takes a String (which will be a path) and will append a
"?random=aRandomNumber" (or "&random=aRandomNumber") to the end of the
input string and returns it.
In Util, also write a public method as follows:
public static ActionForward makeUnique(ActionForward actionForward) {
return new ActionForward(makeUnique(actionForward.getPath()));
}
In your Action classes, where you usually have something like:
return mapping.findForward("success")
you instead could have:
return (Util.makeUnique("success"));
I think this is an ok solution and will work.. But like I said, I think the
gurus in this list will have better ideas (perhaps more in keeping with OO
principles) ..:)

Geeta

Re: success mapping to other module...
Daniel:
Seems like you have too many ".do"s in your success mapping..?
You perhaps may want to do something like this:
-->Change this
and define your goToModule in struts-config.xml in the usual way:
If you want request params added on to the path you may either choose to instead use
request attributes in your UsuarioIncluirAction OR in the UsuarioIncluirAction,
retrieve the ActionForward object using (I'm going from memory here, so you have to
check the correct
method names):
ActionForward af = mapping.findForward("success"); //this will give you the goToModule
bit).
af.setPath(af.getPath() + "..add the request params here..");
and then return (in your UsuarioIncluirAction) the newly created (modified)
ActionMapping..
hope this is clear enough..? (This method actually does work..:))

Re: Passing a vector to a JSP from an Action
Just like Mark said below:

"item" above is an item in your vector "myvector" with a getter for the
property called "myproperty".. Is there something in particular you are having
a problem with..?

Re: Best way to handle big search results..
Jerry: Jacob's note (see below) already says this would be a problem, but he has also mentioned a way to solve your problem; check if that works for you. Store the records in a session variable (that's right, session, instead of request makes sense here!!) and display just 20 or so records at a time. You will have to see if this is feasible.. it will depend on how "strong-big" your server is, etc..:) Regards, Geeta Jerry Jalenak wrote: > In my application I often return large amounts of data - for instance, a > single user may have access to as many as 8500 accounts; each account may > have several hundred detail records associated with it.

Re: Passing a vector to a JSP from an Action
I think you want request.setAttribute(String, Vector) and
(Vector)request.getAttribute(String) (not get/set*Parameter*..).
Btw, don't want to start this off once more, but memory usage is not the only
(or even main?) issue against using session variables.. It's more a question of
what makes sense. But you can just look up that thread for all the gory
details..;)

Re: Form name from JSP page
Hi Stu: This is not really an answer to your question, but just a thought: Why are you reluctant to hardcode the name of the form in? My feeling is jsps are kind of "lightweight" elements so making them more "generalised" is not really that important..? I look at jsps as easily modified/modifiable and kind of self-contained.. unless you envision putting your javascript in some "common" place accessible to lots of jsps, maybe..?

Short answer:
Your class should implement "HttpSessionBindingListener" and override this method:
public void valueUnbound(HttpSessionBindingEvent event)
Long answer:
Below's the code for "ChartDeleter.java" which i got from the open source package
JFreeChart.

Re: ActionForward and onLoad()
Hi Leticia: You're right, I don't understand your question completely (must be because I'm no guru..;)).. But may be you can use this thought anyways: you can use a session variable when you paint your jsp. What i mean is you can test for the existence of this session variable and if it does not exist, add the onLoad stuff in, if it does exist, don't. So if when you submit the form (the first time), you simply set that session variable, you should be home.. (this will work assuming i understood enough o your problem in the first place!!) Good luck!

Re: Must have action="....." in tag?
Stella:
Any time you incorporate Javascript into your app, you have to wonder if things
will work now/ever/always in this/that/other browser. So avoiding everything
except the most basic javascript may be a good idea.
What you want to do can be done more cleanly (just in my opinion though) in the
following way:
Write an interface say "MyRequestHandler" with just one method: public String
handleRequest(MyForm);
write classes like "UpdateShopWorkOrderRequestHandler" and
"CreateShopWorkOrderRequestHandler" which implement MyRequestHandler: all the
work gets done here: You have access to the form bean (via the argument) and in
the end you will return a string (which will be used to create your
ActionForward).
Write a suingleton class MyRequestHandlerFactory: all it does is have a hashmap
mapping "actionCommand" strings to appropraite instances of the RequestHandler:
For example: you may have an entry in the hashmap as:
myHandlerMap.put("updateShopWorkOrder", new
UpdateShopWorkOrderRequestHandler());
myHandlerMap.put("createShopWorkOrder", new
CreateShopWorkOrderRequestHandler());
Write a constructor which will construct your hashmap, and write a getInstance
method in the usual way:
public static MyrequestHandlerFactory getInstance()
as well as a
public MyRequestHandler getRequestHandler (String actionCommand)
which just consults the hashamp and returns the appropriate handler.
Finally, write a "superAction" so:
public class MySuperAction extends Action {
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
String actionCommand = request.getParameter("actionCommand");
MyRequestHandler requestHandler =
MyRequestHandlerFactory.getInstance().getRequestHandler(actionCommand);
String forwardString = requestHandler.handleRequest((MyForm) form);
if (mapping.findForward(forwardString) == null) log.debug("path is
null!"); //this si probably an error condition!
else log.debug("Path is : " +
mapping.findForward(forwardString).getPath()); //bingo!
return mapping.findForward(forwardString);
}
I think this method works quite well and has the advantage of simplicity too..
Hope this helps.. Good luck and let me know if you'd like any more
elaboration..:)

Re: tag doesn't recognize Struts dataBean property'svalue
Jumping in here.. yes, I think you need to trim() before you check. Also, if that too doesn't work, can you check for something "positive" (like if "ShopOrderExist" is equals to "false" rather than "ShopOrderExist" is not equals to "not exists"..?). Another thought, try to get this to work just using oridinary jsp tags and java code (<% java code here %>) and see oif things work. Than you can narrow the problem down to tag issues.. Good luck!

Re: redirect problem
Hi Koen:
Just realised, my earlie solution may result in the annoying alert (in IE) about
whether or not
you want to refresh the page.
So how about "fooling" the browser into thinking this is a "new" page? Attach a
random number
to the end of the url of your forwarded jsp (like
myPage.jsp?id=somelargerandomnumber). You will
have to make this change to the forward in your action, btw.. I remember reading this
technique
somewhere and thinking it a clever solution - except I didn't try it out ..!
Good luck - hope something works for you: life is too short to spend it solving
browser-caching
issues..:)

Hi Koen:
Try adding the foll. lines at the top of your (resultant) jsp:
<%
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");
response.setIntHeader("Expires", 0);
%>
This *may* do the trick.. (I *hate* browser cache problems..(:(..)

Re: How to look up a global forward to get its "path" attribute
I know the following works if you have access to a mapping object (as within
perform/execute):
mapping.findForward("login").getPath();
So maybe you can simply create a new instance of an actionMapping and so forth..?

Re: Form Submission
Mark: Not sure what you meant by your remark about javascript, but I believe javascript was ruled out earky on (not an option or something). The reason I thought saving the user as a session was ok is that I do not believe they are evil (:) either, and further, I can just see this sort of problem recurring throughout his application. Since the user is something that will not change, i felt it's ok to save this as a session variable. (and this I sometimes use as a way to judge whether or not I should save something as a session variable, thus removing the headaches of remembering to reset/remove them).. That said, I have to reiterate that I did not read/understand Avinash's note carefully enough, as you seem to have, so your note may well make more sense than mine..:) Hope this will sustain you without the crack..;) Geeta Mark Lowe wrote: > I said no such thing about javascript. > > I'm in the httpsession != evil school and I'd say this isn't an > occasion where you'd use it as you don't need anything to persist > beyond the request (accept this default action thing whatever thats > about). > > The single action class as a type of command dispatcher sounds > ingenious.

Re: Form Submission
Hi Avinash:
I have not followed your description very carefully - my eyes started
glazing over about mid-way..;) - but here's a thought (and I'm only
going by what i remember of your original question, so forgive me if I
misspeak..): If you do not have access to the request object, do you at
least have access to the session? In which case how about putting the
user in a session variable (maybe right after logon) and then you should
be able to get his/her userId etc etc wherever you want it from..? I
know there has been **extensive** discussion in this list re. the pros
and cons of using session variables and if you are of the
all-session-vars-are-bad school of thought, this won't do you any good.
But personally, this seems to be a situation where a session variable
would come in handy..
If however this idea wn't work in your situation, you may want to
discuss with your clients their absolute requirement about wanting a
link vs. a button (I believe you indicated earlier that the latter case
will pose no prblems for you..?)
Good luck!

Re: html:select
Well, I guess that's what Wendy was suggesting in the first place: make the value and the text the same, that way sending one is tatamount to sending both.. The other option is to use a hidden field and javascript (onSelect fill hidden field kind of thing along with the form.blah-blah[selectedIndex].value that another person suggested earlier..)

Re: Tomcat 3.3.1 and Struts 1.1
Daniel: A fwe months ago I wanted to move to Struts 1.1 and found that unless you upgraded tomcat to 4 or above, at least one fundamental thing would not work. I forget the details of my exact problem, but my situation was the same as yours: I wanted to make struts 1.1 work on Tomcat 3.3.1. I remember searching for a solution and I found that heavyweights like Ted and Craig had thrown their hands in the air and stated that the solution was to upgrade tomcat. Sorry i don't remember the deatils, else I could point you to Ted's note about this.. But i do remember clearly that struts 1.1 and tomcat 3.* don't work well together..

Re: log4j integration
Hi Shankar: Two other people asked this same question so if you don't mind, I'll post my (simple) solution to the list. Btw, for those who don't remember, this is a way to enable changes in log4j.properties to be seen by the application without a server reboot. Here goes: 1. Create a simple action class say ReloadLog4jAction with just a couple of statements in the perform/execute method: Create a new LogManager, then call its resetConfiguration() method. (Write the class within the application context where you want your log4j.properties file reconfigured) 2. Create the appropriate action mapping in your struts-config.xml, so that (say) /admin/reloadLog4j.do would map to this class and maybe redirect to an "OK" page. (am following the way /admin/reload.do works). 3. Reload struts-config either by server restart (or simply by calling /admin/reload.do if you have that mapping in your struts-config.xml.) Of course you will need to do this just once.. 4. Make any changes to your log4j.properties file and then point your browser now to the url /admin/reloadLog4j.do. The log4j.properties file will then be reloaded and after your OK page displays, the new log4j.properties file will then be read in. Really simple and works so nicely..:) Regards, Geeta shankarr wrote: > Hi Geeta, > > If you could let me know how to achieve the integration will be great. > > Where have you written the class which observes the file? > What I mean is, where in the struts framework are u using it at the > RequestProcessor level or what. > As I understand, in order for making the struts application in itself > monitor the file, I need to write some init file only . > Which class to extend and where do I put the entries. > Sample code for the class file and the web.xml entries will be greatly > appreciated. > > Shankar > > "To achieve all that is possible, one must attempt the impossible" >

*Yes*!! The LogManager is the ticket - I didn't know about this class, so tried it out. Works like a charm.. :) Thanks, Shirish (I think?

Re: log4j integration
Please forgive this note if it seems too obvious and I have misunderstood your question/comments.. If you think of both struts and log4j as just a bunch of Java packages/classes, then you will see that "integrating struts with log4j" is really nothing unusual. The log4j jar (or classes in the jar) needs a log4j.properties file (the name of this file is most probably hard-coded in the classes in log4j jar, which is why you don't need to personally tie the file with log4j) and this file should therefore be in the classpath and as you have found out yourself, this is all that is required...If for some reason you need a handle to this file, I don't see why the usual File class in the java.io package won't do the trick..? As for how to ensure that changes in your log4j.properties is made visible to struts, well, I guess you'll have to restart tomcat (or your app server)..(:( I don't believe the admin/reload.do will work (that works for changes to the struts-config.xml and such a blessing *that* is during development!!) ..

Re: form validation question
Ok, maybe, I'd have to check into struts code to really be certain("input"
surely has some significance is what i'm thinking..) So just for the heck of it
though, what happens if you do say "/web/forms/orderForm.jsp" instead?

Re: Struts beginner
Vanessa: Not sure how much help thsi is, but the NoClassDefFoundError is different from the ClassNotFoundError. I have had this error happen when I have *more* than one (conflicting) copy of a jar/class. I *think* what happens is that one jar is used during compile time (depending on the order of items in your classpath..?) and the other jar is accessed during runtime, resulting in chaos. So, maybe you can check to see that you don't have some previous digester jars floating about..?

Re: Form data preloading
Patrice: Here's one relatively simple way of doing this: 1. Extend the struts ActionServlet with say MyActionServlet and make this the controller for your app. 2. In MyActionServlet declare a static var (some Collection say) representing your list of secret answers and write the code to populate it in its init() method. 3. In web.xml ensure that MyActionServlet is loaded on start-up. The list will then be available (on server strat up) before anybody tries to authenticate. (Of course you will have to be careful to update it as and when necessary..) I have heard people mention that extending the ActionServlet is not something they like to do**, but I am not sure that you would be getting yourself into trouble in this simple scenario.. If anybody sees a problem with this, please do chip in..:) Regards, Geeta **P.S. You could of course also simply write another servlet which does this job in its init() method and declare it to load on start up..

Re: server hangs after finite number of requests
Heather: There are many pools out there and I don't feel qualified to comment on which may be the best.. Just use one that seems adequate and you can always go back and refactor your code later.. In any case, my thought is that it is not the fact of the use of the pool that is your problem, rather it is how you use it. If you are careful to release every connection that you acquire from the pool and you ensure that any user has at any time only one connection at his/her disposal, you should be ok. (So it is how many connections a user has at any given time that you should focus on (which is why setting your pool size to 1 at development time is such a good idea), more than the time that that user has it - after all, some database operations just take a while to complete; nothing you can do about that!) Also, remember to close every result set and evrey statement that you open. Otherwise your server hanging problem will be back!

Re: server hangs after finite number of requests
Heather: Sounds like you nailed down your problem. You defintely do not want to hang on to a connection longer than absolutely necessary. So if you get a connection from your pool at say the start of a database access method, make sure you release it back to the pool at the end of that method. Plus make sure you place this code in a **finally* block - so regardless of whether or not your database query was a success, the connection is released to the pool.. Also the earlier suggesstion of having just one connection in the pool during development works perfectly - we have used it for a while now and have been able to uncover errors we otherwise would not have..

Re: server hangs after finite number of requests
Heather: Check any jdbc code you have. If you don't close statements/result sets and/or release connections that you have opened, then this sort of thing can happen.

Oh, ok. I guess i was thinking of the more casual click-happy user who can be perhaps
persuaded to see that overclicking is a bad thing.. But you're right: the scenario you
describe can certainly occur for the more determined lets-break-this-code
user..;) Thanks for setting me right..!

Re: Tokens
Gurpreet:
Don't mean to jump in if you already have found a good solution, but wouldn't it be
simpler to just not allow the user to press the submit btton twice? It is easy (using
Javascript) to disable a submit button once it has already been pressed..

Re: Planning Struts Application Development
What's more, the on-line help on the Expresso list is probably the best I have ever encountered.. In fact, I suspect the lead developer of the project is a vampire so he never sleeps..;) You can also pay a pretty nominal amount for prime support - and if you contribute to their open-source project, I believe you can even qualify for free support!! Re. your earlier question, here's my 1 cent: we have been working on a long (2+ years and counting) project. Version 1 involved a lot of "home-grown" servlets and jsps. Version 2 involved building additional functionality and was written in a combination of servlets and Struts (due to differing degrees of familiarity of the developers with Struts). Version 3 (currently being developed) is written entirely in Struts. I can tell you that every time the clients either notice a bug or want to change or add behaviour, we give a collective groan if it has anything to do with non-Struts code! But if it is the "later" code, we just breeze through it..:) Regards, Geeta Andrew Hill wrote: > You might want to take a look at Jcorporates OpenSource Expresso framework. > http://www.jcorporate.com/ > Ive not used it myself yet so cant give you an experienced opinion, but it > uses struts and provides whole bunch of other goodies which migh help you > get a head start on your project. > > -Original Message- > From: Lauri Jutila [mailto:[EMAIL PROTECTED] > Sent: Wednesday, 29 October 2003 07:04 > To: [EMAIL PROTECTED] > Subject: Planning Struts Application Development > > Hello folks, > > I'm engaging in a web development project and my team is looking at > Struts as a primary framework candidate for the application.

In fact in order to avoid just this last situation, we "disabled" all submit buttons on the page when any one was pressed (and the one that was submitted changed its "face" to a "Please wait..").

Re: newbie session problem
Hi! this doesn't explain why a new session is created, but in the link in your original jsp do not link directly to the second jsp: it's a bad practice anyway since it breaks MVC. Instead use something like this: Jsp 2 In your struts-config.xml, add this action mapping: My guess is you should be alright then..

What is the purpose of this confirmation page? Is this just a display of
what the user has just entered and asking the user if it is ok to submit
now? If the user is happy with the input, (s)he is supposed to click on a
"Done" button and if not, (s)he clicks on a "Cancel" button. Is this
correct? If so, forget about the Javascript, use ordinary Actions to
direct the user to the correct place. and you can just use the

I assume the user is redirected to index.jsp only if there are no errors?
and you are using the form bean validate for checking input errors and so
on. What do you mean to do if there are no input errors but for some
reason the registration is a failure (as in database is done etc.?)

This is wierd. Seems like your onClick method isn't working correctly.
Have you looked at the source of the regisration page? Have you checked
for javascript errors? You could change you confirmSubmit() function so
that all it does is throw an alert so that you know that onClick is
working if you really want to dig into this. On the other hand, if your
specs are such that (as I suspect) Javascript will not even be needed any
more, maybe you can do away with this whole code anyway..

Re: How to do Confirmation page.
Hmm.., maybe I misunderstood you.. But here's what i understood:
According to your initial question, you want to ask the question "are you
sure you want to submit?" as soon as the user hits the "Submit" button,
right? If the user clicks "Yes" you go on ahead with the submission. And
if the user clicks "Cancel", then you don't even submit the form,
correct? All of this has nothing to with Struts, so you don't need to
mess with the strts-conifg.xml for this partiular functionality. What i
have indicated earlier will be enough for that bit..
The forwards for "success" and "failure" (in your action mapping below)
are where the user will be directed to *after* submission of the
registration (ie. after your form bean's validate method is executed and
if *that* is successful, RegisterAction's perform method is executed..)..
(Btw, you are forwarding to /index.jsp in both cases, so yo may want to
fix that..)

Re: How to do Confirmation page.
Hi Dinh nguyen:
I didn't look at your files, but it's fairly starightforward I think.. You
add this javascript code within the of your registration
page. In your case it would be something like this:
function confirmSubmit(){
if (confirm("are you sure you want to submit information?") {
window.location.href ="<html:rewrite
page="/goToHomeAction.do" />";
}
} //end method confirmPrint
And (again in the registration page) your submit button will have code
like this:

Re: How to do Confirmation page.
Hi Dinh Nguyen:
We had a similar requirement and we solved it using Javascript's
location.href .. I reproduce our code below:
function confirmPrint(msg){
if (confirm(msg)) {
window.location.href ="
