RE: Struts custom tags tutorial
In the case, the user described below, I didn't. What he wanted to do was, based on data values, guarantee a color scheme and other criteria, i.e. maybe all negative numbers should be in red. This is view based logic, but one of the priciples we all use is try not to write the same code twice. I might be missing something but, JSTL, and most view technologies (except custom tags, source includes and tiles), don't have the ability to modularize common code or have strange syntax to achieve the modularization. So to say just use the standard technologies and let the view have the view logic is a bit of a cop out. I suspect that most of what he wants to do is already in struts-layout so there is a work around without writing his own tags.

Subject: Can an INPUT tag know its form name? Also, application
resources...
In writing a taglib for my calendar popup, I've come across two
questions:
1) I need to write javascript which references the generated input
tag. To
do this, I need to know the name of the form that it is contained in to
get
a javascript reference to it. If no form name is found, I'll default to
form
[0]. This isn't working:
protected String getFormName() {
// Acquire the form tag we are associated with
FormTag formTag =
(FormTag)pageContext.getAttribute(Constants.FORM_KEY);
if (formTag==null) {
return 0;
}
else {
return '+formTag.getName()+';
}
}
I took this from the html:option tag as an example. Is this not
possible
for the form tag?
2) I have a .properties file for my taglib which defines standard text
and
default options. It would be great if a user could over-ride those
settings
with messages in their own application-specific MessageResources. Is
there a
generalized way, in my taglib code, to get a reference to the
application's
message resources so I can search for keys that over-ride my defaults?
The other option I thought of is that the developer can extend my taglib
with their own and point to their own MessageResources file, but this
isn't
as slick.
Any other options?
PS: Just have to clear up these two things and write more examples and
it'll
be ready for testing...
Thanks!

RE: Suggestions for Calendar Popup taglib?
I love your tag libraries and have used most of them. It is very generous of you to have donated them. One of the problems I had with some struts tags, i.e. html:options, is that there is a repetitive download of the same text. In large pages, especially nested pages, the size of the html becomes excessive, which of course is aggravated by the tendency of struts to force reloads for validation. This problem is repeated in the validator with the same javascript being downloaded multiple times (one reason why I don't bother with validator). When I modified the struts tags to use your libraries, I created separate .js files which were loaded only once. I assume that the struts committers will not want to distribute .js files so when you are putting together your your tag could you keep track of emitting the javascript and do it only once per page. Also, I have some old databases I access which use non-standard data formats. Could you have an optional property to a class/method which would convert the text to a java standard format. Of course you could assume this was a reentrant singleton class and you would only load it once.

If they aren't faster in performance then something is wrong. All the JSP rendering practically has to do is put the code as is into the Servlet which is a Java class. No interpretation. I haven't looked at the source but I am sure the optimization for rendering code for Scriptlets vs JSTL has to be there. Don't be so sure. Because the JSTL is standard, containers can optimize the java code generated from JSTL tags. This means a c:if tag can be converted into a real Java if statement instead of creating tag instances and invoking the tag's lifecyle. My understanding is that the Jasper JSP compiler (comes with Tomcat) actually generates faster Java code if you *don't* use scriptlets at all. Resin and Tomcat both optimize JSTL tag usage. So, with the JSTL we get the best of both worlds: Fast page rendering and standardized, powerful and easy to use markup tags. David __ Do you Yahoo!? Yahoo!

RE: [OT] RE: JSTL ot struts taglibs?
You are not alone is questioning the solutions to the view problem. This is an interesting problem and will really challenge the open source community to solve it. Right now, everyone has an opinion, no one has a real solution, each individual users needs are limited (they tend to solve their particular needs and move on) and the problem is EXCEPTIONALLY complex. Part of the problem is that there are so many ways (none of which are particularly good compared to .NET) to paint pages in Java land. JSF is vapor and has a limited window of opportunity and requires REAL industry support to succeed before the world moves past it. .NET view technology looks really tempting from the outside and there are statistics which support that it enhances developer productivity (this will have a greater importance as time passes). The individual with the most influence in the space is Craig, which is why JSF is seen as an overall solution. Unfortunately, many in the community disagree with him and with JSF. I wish, I agreed that JSF was the answer and that if we all jumped on the JSF bandwagon, the industry could move past this problem, we could have great IDE's for view creation, etc. Anyway, this is a real challenge facing the community with very strong pressure being applied by MS.

If you need this to work the way you are describing, I would use a hidden

javascript to link up a checkbox to 1) set the checkbox initial value; 2)
toggle the hidden field when the checkbox is toggled; and 3) loose the

Ah, but if you dont reset the checkbox it will always stay

for an unticked checkbox so the forms setter method is never called.
THIS is the real reason the reset() method even exists in the
first place - its a workaround for this flaw in the html

multiple-select boxes and textareas. Empty input fields will
submit an empty string so they dont need to be reset, and
single selects always have something selected so dont need it either.
If your doing wizards you should still call reset() but you
do the selective stuff inside the code for the reset() method

Subject: Re: Is this really the best way to handle this problem
I've seen two ways of dealing w/ this problem, both of
which I see as
'hackish'
in nature.
Solution A:
In your getters/setters you implement the following code
public MyCustomBean getMyCustomBean(int index) {
while(index = myCustomBeanList.size()) {
myCustomBeanList.add(new MyCustomBean());
}
return (MyCustomBean)myCustomBeanList.get(index);
}
In that way you'll never encounter the common
IndexOutOfBoundsException.
The
problem here is that you tend to use alot of hidden fields
in your UI
to
repopulate
the data back into the dynamically created beans.
Solution B:
In your reset() method you repopulate your internal Collection of
beans.
The
problem w/ this approach is that often times you have a separate
Action
that
prepopulates your ActionForm. This provides for good
separation - the
Action
is a retriever of a data (nothing more) and the ActionForm
is merely a
container
for data (nothing more). With this approach your
ActionForm suddenly
starts
becoming more intelligent than it really should be. Now
it's aware of
how
to
populate itself...not a good thing IMO.
I'd be very interested in hearing other solutions to this
problem as I
find
both of the above solutions cumbersome and hackish and
would love to
stop
implementing
them.
I've been struggling with a problem similar to the one
described (and
solved) at
http://www.mail-archive.com/[EMAIL PROTECTED]/msg50901.h
tml
.
Is this really the recommended way to solve population /
repopulation
of properties stored in a List() of
whatever-data-object-i-need-in-the-form-of-a-bean ? Is
there a better
way
to
acheive the same result ? (I.e represent a collection in a form)
I've read that a practice often used to represent collections (a
DB-table for intstance) is to make a bean that has getters
/ setters
for the properties of a single row and then have the ActionForm
contain a List()
of
those beans. One for every row (in the DB-example). That far I can
follow,
and see how / why. But is there no better way to update
the values in
the ActionForm (beans) when the data is submitted than in the URL
above ?

Do I create an array for each row in the resultset and insert each array in a collection, passing that back to the view? That is certainly one approach. Indeed, commons-beanutils has a useful little class (org.apache.commons.beanutils.RowSetDynaClass) that is ideally suited to this use case. It creates a List of DynaBeans representing the data content returned by the SELECT. Because it makes a copy, you can close the result set (and return the connection back to the connection pool) before forwarding to the page. If so, how would you iterate over each array in the collection with the logic:iterate taglib? All of the examples only show iterations over single column lists. Let's assume you have done this in your Action: ResultSet rs = ...; RowSetDynaClass rsdc = new RowSetDynaClass(rs); rs.close(); request.setAttribute(customers, rsdc.getList()); so you now have a request attribute containing the list. Now, in your page, you can say things like: logic:iterate id=customer name=customers Name is bean:write name=customer property=name/ Status is bean:write name=customer property=status/ /logic:iterate and so on.

Ok well lets suppose you want to protect 100% of your content, perhaps minus the login.jsp or what not page. For container managed security, a /* pattern is how you'd specify this -- the container knows that the login page should not be included in that (although I suspect various Tomcat 3.x versions had problems with this). We just spent a couple hours brainstorming how to protect our webapp. We want flexibility above and beyond what container security provides, so we want to use our own mechanisms pulling permissions from a database etc. So we we have had two veins of thought. 1) Creating some kind of struts action that handles all incoming requests, where the web.xml maps /* to struts and it handles it, by using the wildcard extension to map everything minus actions to a certain struts action, that can perform authentication for that resource, if permissions match ship it on, otherwise forward to an error. 2) Create a servlet that runs within tomcat that takes all requests, performs authentication, then ships it to either struts for actions or wherever else for resources. We only want to use tomcat4, not apache or anything.. these seem to us to be the only ways to get a good flexible handle on what people request and see. #1 would be something we would rather use because it requires only one running servlet which would be struts, whereas #2 would need 2 servlets. One of the keys to container managed security is that you need to be able to express your authorization decisions (what can the user do) in terms of roles. A role can be as coarse-grained or fine-grained as you want, and many users can be assigned the same role. Generally, the set of roles owned by a user is statically determined by the container at login time, but that is not mandated by the spec -- it's perfectly legal for a container to implement a role (for example) that is assigned if it is now 8am-5pm on a weedkay, but not other times, to allow access to a particular resource only during working hours. The second key to effective use of container managed security is that you can express access control decisions to particular URLs (or URL patterns) in terms of an AND test between roles. If you cannot do this; perhaps because there are factors besides roles innvolved in the decision, you might want to think about rolling your own security -- in that scenario, a filter is probably your best bet. Within Tomcat itself, there are several avenues to customizing the behavior of container managed security, but they are all Tomcat specific: * You can define your own Valve (the internal-to-Tomcat equivalent to a Filter), and cause it to be run either before or after the Valve that actually implements container managed security.

So what is the difference? When to use what? A couple of very incomplete thoughts: * Digester is one way (XML-Java), JAXB is two way (XML-Java and Java-XML). * Digester is nice for pulling just a few things out of an XML document, JAXB typically wants you to process the whole thing. * Digester rules can be calculated and constructed on the fly as you configure the Digester, and include some interesting matching rules that mean you don't always need to understand the entire document structure. JAXB is more like DOM, giving you a tree structure to process. * Digester lets you deal with dynamic sets of attributes gracefully (i.e. the SetPropertiesRule, for example); JAXB wants you to know them ahead of time. As with most things, it's kind of hard to say that one approach is always going to be better or worse; thinking through both approaches for each use case is probably the best approach -- in particular, I'd implement a couple of simple use cases both ways to see which one appeals to you more.

I can not find original post from Thorin - but I'm 100% agree with his point. Moreover - I have real experience with system that allows me to implement what Thorin is talking about. We implements almost all business logic in controller layer, moreover - we have two sub-layer inside controller - presentation controller, which handles all page flow and input validations, and business controller - where actual business logic where implemented on high level. All this because of using our own implementation of MVC framework - Exadel. I'm not here to convince you to switch from Struts to Exadel, but I can tell you that Struts controller component is too primitive compared to Exadel. We used widely concept of module. In Exadel you can define module (we call it process) with process context and actually use it like function calls. You even can use recursion. That gives us ability to split system to modules using vertical (by functional areas) and horizontal (by architecture layer) approach. And we design system in a way where we have two horizontal layers - one (top) designed to handle page flow and all interface relater issues. And second (bottom) layer was dedicated to business functions. I feel that there is something good in such design, the only problem - Strut do not really helps here.

As they are both web controller architectures, they have many similarities, but I'm running into one difference in overall architecture that I'm having difficulty resolving. This difficulty is most closely related to the 'action chaining' posts I've been able to find in the mailing list archives. Specifically, I have over 400 pages mapped to various actions (our controller calls them that, and they're roughly synonymous with struts actions.) However, our controller allows specifying a list of actions to execute on a per-page, and per-page-set basis. In other words, we can assign an action like 'Ensure Session initialization has been completed/Initialize session' to every page in the site with a single mapping (assuming you've already listed all the pages.) Or you can assign it to 90% of your pages if you happen to desire. We have approximatly ten actions that happen on between 60-99% of the pages on our site. If we were to directly translate this to the struts mapping system we would end up having to re-specify those ten actions on most of those 400+ pages, creating long action chains for

All kidding aside the upgrade will be a little time consuming but should not be a painful one. You are not using modules or tiles so I don't believe there are any struts-config changes that will impact you. If you were using the external nested tags you will have to dispense with extra jar. If you were using any of the commons packages you will be upgrading those so check those issues separately. There are many deprecations but if you have an ide those are relatively minor, i.e. perform -- execute. If you have any automated test sequence that will help as well.

RE: Formatting dates in html:text
If you just want to display, the bean:write tag has some date formatting
options.
For entry the 'best' current solution is to subclass the TextTag class and
do your processing there. The strategy I have been using in such a tag is
to use a 'hidden' field with your actual form data and javascript to do the
translations to another field the user actually edits, of course returning
the altered text to your hidden field.

RE: Including A JSP Containing Struts
If you use jsp:include this is a separate compilation and is more like a function, hence the 'parameters'. However, what it sounds like to me is you are looking for a 'c' macro facility with parameters. I don't believe this functionality is available. If you use the straight text include it is a parameterless macro. Since we are in a servlet environment, stick the parameters in the request and in your include pull them out of the request.

RE: Struts-Menu onClick forcing a submit
It is puzzling why you would be using the 'menu' instead of on page links or
buttons to submit the form.
There is no way to do it using struts-menu selections w/o javascript as they
do not render submit buttons.
If your menu is within the form /form block try
onclick=document.submit();
Also, you might want to use page instead of location although I don't think
that is your issue. Page is for same site references, location is for off
site references.

Subject: Struts-Menu onClick forcing a submit
Hi,
I am using Coolmenu4 and setting location to the URL to
execute e.g. location=ServiceInvoice/save.do.
I found that this does not force a submit so my action form
is not populated. To force a submit I tried the
onClick e.g. onClick=submitSave('ServiceInvoice/save.do').
This does not work. The digester that loads the
menu-config.xml doesn't like the parameter with single quotes.
I tried double quotes and escaped double and single quotes
but no luck. e.g. onClick=submitSave(\ServiceInvoice\save.do\)
How can I pass a parameter using onClick?. If it is possible
to force a submit using the location, page attribute or other approach
I would rather do it that way without using javascript.
Any help would be appreciated.
Thanks,
Jack

RE: Struts-Menu onClick forcing a submit
I would have a hidden field which would help you decompose the action
selected, since there can be only one submit target. You can use the
LookupDispatchAction as a model or you can simply fill the value of the
hidden field with your action code, i.e.:
onclick=actionField.value='save';document.submit();
Then in your action look for the value of 'actionField' (it would be in your
form or in the request parameters).

Hi Edgar,
It's a user requirement to use a horizontal dropdown menu to
initiate actions. For example the menu would look like:
[Home] [Action] [Query] [Add][Save] [Delete]
Cancel FieldQueryNew Delete
ClearList All Add Detail Delete Selected
ResetNew Query
There are different menus based on the screen being displayed.
The action class has a number of methods for the above menu. Some of
the menu actions will take you to another action-to-screen.
Long term the menu options will be selected from a database
table or XML file based on the userid and password.
If I use the onclick=document.submit(); I will still need
to set the forms action to the new url.
Thanks for the reply and suggestion.

Hello
I am trying to do this:
html:button property= someButton

/html:button
Basically trying to pass a dynamic variable as arg to java script
function
within the struts html:button tag.
I know I can build up the string in scriplet code like this
% String temp = doSomething( +dynamicvariable + ) ;%
And then use this in the button tag
html:button property= someButton onClick=%=temp% Do
Something
/html:button
but, I do not want to use that solution.
Your only other choice (AFAIK) is to use Struts-EL, but
that's a bigger change than building up the string in a
separate statement. Using Struts-EL, it would look like this:
html-el:button property=someButton
onClick=doSomething(${somedynamicvariable})
Do Something /html-el:button
This assumes you created somedynamicvariable as a scoped
variable (not as a scriptlet variable).
If you're not familiar with this, it uses the expression
language mechanisms specified in the JSTL specification (and
the apis defined in the Jakarta Taglibs implementation of the JSTL).

A form based sequence token (as opposed to struts session based token) reduces users frustration with the lack of a back button.

Hasnt got to that stage yet, but Im guessing that the js trick wont be particularly 'appreciated'. Of course that code is centralised in one javascript file, so can be changed once Ive had a chance to get tokens working, but Im going to need some fancy code to handle the situation where the url of the previous page is resubmitted as theres a fair bit of stuff that has to go into the session context that wont be there any more if they have completed that operation and then try to go back into it. Life would be a lot easier if this was just a website with some interactive bits, however its very much more in the nature of a complex application with bucket loads of state that happens to use a browser instead of a standalone client and so theres a lot more 'funny stuff' going on behind the scenes than your average struts app would have - none of which plays well with the back button (or refresh multiple submit for that matter). :-( I've been known to discourage the use of the back button by opening my apps in a browser window that doesn't have the usual location bar and back button icons -- it doesn't help you defend against people that know the keyboard shortcuts, but I was pretty happy with how much this simple approach cut down complaints about the back button not working. Of course, it's incumbent upon the app developer to include enough nice navigation controls in the page layout so as to minimize the temptation to use the back button in any case ... :-) When you get that (rare :-) *rational* user that complains about the back button, ask them to show you where the back button is on any traditional GUI app, and then ask them why it should work in a web *application* as opposed to a web *site*.

RE: struts-menu
Struts menu works nicely with struts, i.e. you add a plugin to read your configuration files. It uses xml and property files for menu configuration. It can use javascript or not and works with CoolMenus. There are a couple of jsp tags which actually insert the menu so your jsp files stay really clean. The things I like best about it is that the menu positions are relative (at least the simple and drop down displayers), i.e. you don't have to put pixel positions in your code and the menu config just has information actually relevant to the menu, i.e. url, description, and a tooltip. http://sourceforge.net/projects/struts-menu Edgar -Original Message- From: Stephen Smithstone [mailto:[EMAIL PROTECTED] Sent: Monday, March 10, 2003 10:38 AM To: 'Struts Users Mailing List' Subject: Re: struts-menu what is this struts-menu and where can i find some examples / downloads ? please On Monday 10 March 2003 3:22 pm, Raible, Matt wrote: Edgar, I'm a committer on struts-menu, so hopefully I can help you out.

The ambiguity of the syntax is disconcerting and is probably why I limit

I didn't find the benefits of the use of jstl extention.
Who can explain me the benefits ?
From: p2 - apache [EMAIL PROTECTED]
Some body don't want to see % %? Just a guess.
There's lots of advantages to the expression language that
Struts-EL uses (copied from JSTL 1.0, and to be embedded
everywhere in a JSP page in JSP 2.0). My favorite feature is
independence from the underlying implementation of the
properties. Consider the following expression:
${customer.mailAddress.city}
This works for all of the following scenarios (as well as
some others):
* customer is a bean with a getMailAddress() getter, which in term
returns a bean with a getCity() getter.
* customer is a bean where getMailAddress() returns a Map that has
(among others) an entry with a key of city.
* customer is a Map that has a key mailAddress whose value is a
bean with a getCity() method.
* customer is a Map with a key of mailAddress that returns a Map
that has a key of city ...
You get the idea? The business tier developer has a fair
amount of freedom in how they implement the beans
representing the data required by the view tier -- or even
skips implementing them if Maps do the trick. And changing
your mind among these choices does not invalidate the syntax
of the expression that is embedded in your page.
The other thing I like about EL expressions is that the
syntax is very close to what page authors familiar with
JavaScript already understand, so it's natural for them to be
able to script with it, without having to know any java at
all. Consider a personnel management app that wants to
restrict the display of salary information to managers. In a
JSP 1.2 environment (with JSTL), you could write:
c:if test=${user.role = 'Manager'}
c:out value=${employee.salary}/
/c:if
and have a fair chance that the page author can understand it
-- while the corresponding scriptlet version is pretty opaque
to a non-programmer:
%
if (user.getRole().equals(Manager)) {
out.println(employee.getSalary());
}
%
to say nothing of the fact that the Java code requires you to
expose user and employee as instance variables in the
page class, while the tagged version doesn't. (And, by the
way, you'd better be prepared for NullPointerException errors
in the scriptlet, while the expression language deals with
them for you.)
By the way, in a JSP 2.0 environment, this example will get
even simpler:
c:if test=${user.role = 'Manager'}
${employee.salary}
/c:if
because you will be able to use EL expressions anywhere
(including template text), not just in tags that understand it.

RE: FW: Running unit tests for Validator used with Struts
You should be able to validate with StrutsTestCase since it uses cactus.
You have access to the request through cactus, the ActionErrors is stored
at Globals.ERROR_KEY or returned from your validate. So, you can manually
instantiate ActionErrors. You can manually instantiate a mapping, although
I doubt you use it in your validations. You can manually populate your
form. I test my validations through successful action results so I don't do
this but the following should work.
...Instantiate form...
MyForm form = new MyForm();
form.setMyProp(value);
... Other properties ...
ActionMapping map = new ActionMapping();
... You have access to the request in StrutsTestCase ...
HttpServlet req = this.getRequest();
... No sure about this but I don't think config is frozen if you declare the
map w/o config...
FowardConfig f = new ForwardConfig(name,url,false);
Map.addForwardConfig(f);
... No we can validate ...
ActionErrors ae = form.validate(map, req);
... You can use the strutstestcase valiations by sticking the errors in the
request
Req.setAttribute(Globals.ERROR_KEY, ae);
... I think you are done ...

Subject: Re: FW: Running unit tests for Validator used with Struts
Hello Edgar,
I already am using StrutsTestCase to tests
Actions I write. I see how that could be
used to test whether validation works, but
unless I'm missing something testing of
custom validators this way would really be
just a side-effect of testing Actions.
So imagine you have an Action A that uses
Validator V. I write a STC-bases unit test
and run it. It passes, no problems. One
day somebody modifies A to stop using V and
modifies V and breaks it.
My STC-bases tests keep running and passing,
because A still works, but I will never find
out that V is broken, because V is never
really tested directly.
A new developer is hired and writes a new
Action, AA, and decides to use V. V is
broken and his AA class is now broken
because V is kaput.
One could argue that AA should have its unit
tests, too, and that those should show me
that V is (has been) broken
So I will use STC for testing the Validator,
too, but I'm wondering if there is better,
more direct way of testing them?
I can test them directly when they are
Struts-independent, but when they depend on
Struts (e.g. by taking some Struts classes
as params), then I cannot.
Thanks,
Otis

Subject: Q: Running unit tests for
Validator used with Struts
Hello,
It is almost impossible to get anyone
attention on struts-user.
I'm using Struts and Validator with it.
I wrote a custom Validator and want to
write
a unit test for it.
My Validator has a method like this:
public static boolean validateStartLetter(
Object bean,
ValidatorAction validatorAction,
Field field,
ActionErrors errors,
HttpServletRequest request
)
{
String value =
ValidatorUtil.getValueAsString(bean,
field.getProperty());
if
((GenericValidator.isBlankOrNull(value)) ||
!Character.isLetter(value.charAt(0)))
{
errors.add(field.getKey(),
Resources.getActionError(request,
validatorAction, field));
}
return errors.isEmpty();
}
I am running JUnit from Ant to run my unit
test class.
Apparently this doesn't work because the
instance of ActionErrors passed to this
method is null, causing a NPE.
I wanted to check the unit tests for
Validator in Struts (FieldChecks) to
see how
you wrote your unit tests, so that
this NPE
is avoided, but I could not find any unit
tests for it.
Are there really no unit tests there?
Regardless, how would you go about running
unit tests for a custom validator from
something like Ant?
It seems to me that doing that may be
impossible, because there is no Struts
running to instantiate ActionErrors, there
is no HttpServletRequest, and so on.
Is there a way to do this?

The only way I found was to do the following: Turn on validate. Don't return the errors generated, put them in the request under the Globals.ERRORS_KEY. This way, the ActionServlet will not return immediately to prior page but the ErrorsTag will still know where to find the errors. Save the last action map in your form in the prior action. All you need is the string. At the start of your action pull the errors from the request, if there are any errors, and return to the mapping you saved in your prior action.

RE: monkey tree - must be session-based?
Question about session access. No idea... Question about multiple browsers in a single session: Put a sequence number in your form and your jsp. Similar to the one struts puts in the session. I don't like that one since it really restricts the user movement, i.e. they can't be working in a form, jump to another form for some info and return. Always validate. In your validation check the sequence number in the form vs the jsp. If not equal, fail the action. In my case I am usually doing data entry. If this is a new record, I just warn of the sequence / session problem. If its an old record, I re-read the data. The actions you choose will depend upon your circumstances.

Struts Console
James or any other Struts Console maven: I have started working more with Struts Console and find it interesting since it is always presenting all the options available on actions, etc. Also, that it is doing xml validation against the dtd is very nice as well. I still do enjoy using my editor (emacs) on the config files for cut and paste and search and replace, but find the default struts-console xml output format difficult. Is it possible that struts-console 'pretty' will not toss comments and also be available under eclipse? Even better would be the ability to add comments to each xml property. Better still would be a 'copynew' function for major items such as tiles-definitions and action mappings. Of course if you do 'copynew' you would need search and replace. I hope you take this commentary in the spirit in which it is meant, as a thanks for a program useful enough to be worth commenting about. Thanks Edgar

Hello, hoping for some help on this:
The nested:iteration on a Bag seems to work fine, and it iterates ok,
but I am having trouble accessing the contents of the Bag (SortedBag or
TreeBag etc)
from the code, please help :)
nested:form action=engtest.do
logic:notEmpty name=_engineer property=products_SortedBag
nested:iterate property=products_SortedBag indexId=i id=unused
%=i%
html:text property='%=products_SortedBag[+i+]%' /
/nested:iterate
/logic:notEmpty
nested:submit property=submitValueSubmit Changes/nested:submit
/nested:form
Returns:
java.lang.IllegalArgumentException: Non-indexed property for
'products_SortedBag[0]'
And if I try,
html:text property='%=products_SortedBag(+i+)%' /
it returns:
java.lang.IllegalArgumentException: Non-mapped property for
'products_SortedBag(0)'
Using nested:text gives the same output as well.
So how can I access the contents??
Thanks!

The LookupDispatchAction was designed with the intention of not having to
use javascript to work with multiple submit buttons in one form.
Since what you need is a submit from an onChange event in a text field which
is a somewhat not often seen operation (at least from my experiences), you
have no choice but to do the javascript in this case.
Just our of curiosity, what requirement in your application do you have that
needs the form to be submitted when a text field changes???

Subject: RE: LookupDispatchAction onchange
If I remember correctly the LookupDispatchAction does a reverse lookup on
your resource bundle in order to determine which method to call in the
class.
Example:
if you have a key in your ApplicationResources.properties called:
textfield.changed=submit form
then you would obviously need something like the following in the
getKeyMethodMap:
map.put(textfield.changed, textFieldChangedMethod);
So when your text field changes, you will need to submit the parameter you
configured for your LookupDispatchAction in struts-config.xml with the a
value of 'submit form'
What the action should do is do a reverse lookup on the ApplicationResources
file and look for a value of 'submit form'. 'submit form' is associated with
the key textfield.changed and it will cause the textFieldChangedMethod to be
called in your class.
Also, make sure you follow Andrew's suggestion about not using 'action' as
the parameter name. This has the potential to cause your form to behave in a
very weird manner. It caused me lots of headaches in the past until I
figured out it was the parameter name I used was 'action'.
If you need any more help on this let me know.
Take care

Subject: RE: LookupDispatchAction onchange
Should be possible.
You may need to do something like appending a parameter to your forms action
url with a bit of javascript to simulate whats submitted by a button. Can't
remember the details for LookupDispatchAction since I havent used it, but
heres some js that will play with your forms action and append a parameter
named 'method' with value defined by useMethod. Adapt as required. (nb: its
modified from a similar script (which works with DispatchAction rather than
LookupDispatchAction) of mine for the purposes of this reply and thus
untested!)
snip
function submitBlah(useMethod)
{
document.forms[0].action =
appendParameter(document.forms[0].action,'method',useMethod);
document.forms[0].submit();
}
}
function appendParameter(url, parameter, value)
{
var delimeter = url.indexOf('?') == -1 ? '?' : '';
return url + delimeter + parameter + '=' + value;
}
/snip
Having said all that I should point out that you might be able achieve a
similar effect using an appropriate hidden field too. Much simpler (though
doesnt work too well with multipart forms submitting to a DispatchAction).
If you try that be careful you dont submit 2 values for your property when a
button is clicked.
btw: Just looking at the javadocs for LDA. I see they use 'action' as the
name of their example parameter. Bad idea naming anything on a form
'action'. It will shadow the form.action property (which means above script
wont work for one thing). Same reason that naming a button 'submit' will
lead you into trouble when you later try to add a call to javascripts
form.submit() method...

to know how many lines the user is going to enter, so i'd like them to
have
some kind of way ( maybe a button ) that the user can click on, the page
refreshes (retaining data) and shows a new blank line at the bottom of
the
page under the other lines. When im talking lines I mean eg. Name,
Location,

RE: Is Struts (or browser based applications in general) useable to build maintenance-applications?
I have resolved all my Web Application issues (it did take a while). The back button can be solved by subclassing the ActionForm and having a standard sequence field. In all your JSP make sure there is a hidden field for the sequencer. Then before any action occurs (write to the db) check the sequencer to make sure it is the value expected. If you only use POST methods in JSP the bookmark issue is moot.

Well I dont know what the issues with maintenance apps in particular are, but for any web app (which is an application rather than just some trivial website or portal with dynamic bits) you will have a lot of issues with users doing things like using back buttons, bookmarks, etc... which can really upset your server side sense of application state. Managing this can be a real pain.

Unless your users are happy with a very minimalist UI (Ive yet to meet one who is) thats something of an impossibility so you have a lot of decisions to make in terms of what and what not to support. A lot of things that might take only a few lines of code to achieve in a Swing based client can be fiendishly complex in html (keeping your state maintained correctly in relation to what the user is seeing on their screen, fancy widgets, modal stuff...) On the positive side, your users wont need to install a client application onto their machines which makes rolling out changes a lot easier (and for a big organisation a LOT cheaper). In addition a lot of things that require tons of code in Swing can be achieved relatively easily from a browser UI.

We are in a decision-process about the front-end for a maintenance-application in insurance-domain. The communication with the backend (mainframe) happens via XML. This front-end infrastructure should be the base structure for new applications (not only for the maintenance-application). So my preference is to build a browser-based front end with Struts :-) But I'm unsure about the useability of a browser based front-end in maintenance context ( - keyboard-navigation, etc.). I know, several things can resolved with Javascript. Is it a risky way to develop a browser-based front-end for a maintenance app. Can someone share experience to build maintenance-apps with struts (or a browser based front-end in general)?

RE: Is Struts (or browser based applications in general) useable to build maintenance-applications?
Quite correct, I (and somewhat reluctantly the user base) have accepted the limitations of the back button. There is no risk to the database however. I give users as many of those links you describe as possible but only to informational pages, and with container managed security (or filter based security) they maintain some of what the users desire for flexibility without sacrificing application integrity. Interesting commentary. Thanks. -Original Message- From: Andrew Hill [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 26, 2002 10:51 PM To: Struts Users Mailing List Subject: RE: Is Struts (or browser based applications in general) useable to build maintenance-applications? Ive a quite lot of links that look like thingAction.do?method=edituid=1234. As I go along Im rather coming to the view that I should just try and use POST for everything and eliminate GETs altogether. The browser just takes far too many liberties with them... The sequencer idea has merit (seems similar in concept to the token token support struts already provides), but the problem is that they want the damn back button to actually work. Given that the app needs to maintain fifty tons of state (including state of various ui widgets, workflows and other wierdities) to meet all the other requirements its very hard to figure out a suitable way to handle this short of incorperating a TARDIS in my application. The basic problem of course is the app vs website dilema. In a website the back button is very useful as your just navigating round a bunch of relatively stateless pages and a request is a direction for which page you want next. In a web app however you arent navigating round a bunch of pages, but rather firing events to the server that cause changes in server state which are reflected in the response page. Clicking the back button would cause the last 'event' to be fired again, or a snapshot of an earlier response page to be shown, but the server is already in a different state. The last event was already processed. Database writes have been commited. Objects created or destroyed. Widgets toggled and workflows woggled. Keeping a token gives you a chance to tell if the user is submitting from an earlier page cached in the browser, and you can show an error message and perhaps even direct them back on track - but when your requirement is that that old page work again just like it did before, its nearly impossible. It will work in some cases, but in others you can end up with all sorts of problems if there are things that depend on server side state as well as client side state - and in all but the most trivial of cases this will be true. What to do? :-( Its hard enough to try an explain this problem to the (more experienced technical) people who give me these requirements. I hate to think how the concept can be imparted to users... -Original Message- From: Edgar Dollin [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 26, 2002 19:02 To: 'Struts Users Mailing List'; '[EMAIL PROTECTED]' Subject: RE: Is Struts (or browser based applications in general) useable to build maintenance-applications?

struts-config
Has anyone ever worked with forwarding to a servlet as opposed to a jsp page? The controller handles that well as the only association the jsp page is to the ActionForm and the actions are independent of the jsp. From my reading and tests It looks like you can't forward to another Action class, which would be ideal. You have to forward to a HttpServlet pick up is the original requests ActionMapping (request.getAttribute(Action.MAPPING_KEY)) or the WHOLE action map (context.getAttribute(Action.MAPPINGS_KEY)) and do you own decode. All this is workable, just wondering if I am missing something in my analysis. Thanks in advance. Edgar P.

RE: [OT] Newbie Design best practice question
You might consider writing custom tags of the form custom:fulluser functionality for full user /custom:fulluser etc. This would keep the jsp simple but allow you to localize the functionality. Edgar -Original Message- From: Piper, James D CECOM SEC EPS [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 17, 2002 2:05 PM To: [EMAIL PROTECTED] Subject: [OT] Newbie Design best practice question If I were to have a STRUTS enabled application where I had user types of restricted_users, full_access_users, and admins and for the most part the content of the screens the different user types get to see are the same, except for maybe Id like there to be a few extra bits of functionality on the full_access_users and admin screens that doesn't get shown on the restricted_users screen, then what's the best way to go about this? It will probably also be that each user type will require some Action objects not used by the other user types. Should I attempt to use one set of JSPs for all the different types of users and put logic inside each of the JSPs that says something like 'if the user is of type full_access_users then shown these extra few buttons', or should I give each type of user their own set of JSPs? I am tempted to try and use one set of JSPs for all user types so that I don't have to worry about maintenance of three sets of almost identical JSP files. On the other hand I feel I may be asking for security trouble by trying to have each JSP check for the user's user type - I also have a notion that checking user types is something that I should be doing elsewhere. If I do use separate JSPs for each user type, would it make sense to use the STRUTS sub-application mechanism to separate them out?
