RE: About *.do

[David G. Friedman]

See section 5.4.1 and 5.4.2 on the Struts site for how to map your action
path such as "/login" to be either "/login.do" or "/do/login" on
http://struts.apache.org/userGuide/configuration.html

Again, the do (/do/* or *.do) part is customizable.  Some people posted
about messing with people's heads by mapping every action to *.aspx instead
of *.do to mess with their boss' head. :)

David

I agree with Craig.
OzStruts does same thing for you with OzPage.prepareRequiredProperties()
even on the curent verion of Struts. then codes will be like what Craig

Yes. This is the case for those who want to try.
Now i can take time to dig in a little deeper and may have some question

Re: JNDI

[Jonathan Wright]

Craig,

Thanks for the prompt reply. I have in the past set up DataSources in
Tomcat's server-config.xml. However, due to the nature of our production
environment I don't want to edit this file. It's relatively important that
my web apps are completely self contained.

Why not use the JNDI naming context provided by your container?  You
shouldn't have to be worried about implementing this -- just configure
the JNDI resources that you want to make available to your
application.

For example, the instructions for using the naming context provided by Tomcat:

  http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-resources-howto.html

and specific info about using a data source provided by Tomcat:

  
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html

Other servers will have their own mechanisms for configuring these things.

Both are supported.  For more info start at:

  http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/index.html

and, in particular, look at the  element.  This element can
either be buried inside a server.xml file, or in a separate
configuration file under the server's configuration directory, or
included in the META-INF directory of a WAR.

None of this has anything at all to do with Struts ... it's going to
be some sort of documentation on your app server if it is possible at
all.

JNDI

[Jonathan Wright]

Hi,

Just a quick question about JNDI in a Struts setting. I want to reduce the
dependencies between objects in my app. Some objects that are not servlet
aware need access to the ServletContext and DataSources. However rather than
complicating matters and increasing the number of arguments I need to pass
around I'm thinking of putting references to DataSources and the
ServletContext into a JNDI context.

Which JNDI SPI would you recommend for a simple object registry/store? What
are the issues regarding the Referenceable interface?

Thanks in advance.

And one more critical one ... by default, the build script assumes you
have JSF installed inside your container already.  If you don't add
the following line to build.properties:

  build.standalone=true

This is probably what's triggering your error.

Re: contrib/struts-shale-mailreader

[Craig McClanahan]

There's another dependency when you try to compile
struts-shale-mailreader ... you have to have run the "dist" target on
the shared database code in "struts-examples/mailreader" first (along
with "struts-contrib/struts-shale" of course).

You will also need to make sure you've set up a build.properties file
that points at the dependencies ... in particular, define "jsf.home",
"jstl.home", "junit.home", and "server.home" appropriately.

Re: Struts app to be passed a parameter (of some kind)

[John Vincent]

App Server is WebLogic 8.1. 

I can try SunOne Application Server also.

On Tomcat, do you configure the app xml files? Or is it configured at the 
server level?

In other words, do I need to check the app server doc or the weblogic*.xml 
or sun-*.xml files doc for the Struts app?

What app server are you running?  The setup to accomplish this is

The example I gave, as I stated in the response, was specific to using

When we switched to Subversion, the CVS repository was frozen as of
that particular date (i.e. anyone who tries to do a commit to that
repository will get a failure).  That being said, there are thousands
of links into that repository (typically through the viewcvs portal)
that would suddenly break if the old repository was physically removed
-- that doesn't seem like a user friendly thing to do, so we didn't.

For general SVN background, start at 
and read the walk-through chapters of the book -- it's a pretty good
introduction.  For those familiar with CVS, there's even a specialized
chapter on mapping the "CVS way" to the "SVN way" which I found very
helpful.

Re: Struts app to be passed a parameter (of some kind)

[Craig McClanahan]

What app server are you running?  The setup to accomplish this is
going to be specific to that app server, if it is possible at all. 
The example I gave, as I stated in the response, was specific to using
Tomcat.

Re: Does Javascript Validation work with mapping path as key?

I'm not sure what you are getting at here - from what I can tell from 
the code you posted, the form name and mapping name are the same, so 
either way it shouldn't make a difference (But see my comments below as 
well...)

Where do you expect myForm to come from (or not come from?)
What happens when the javascript validation kicks in? Javascript errors? 
Java errors? Nothing?

Can anyone see what I'm doing wrong or confirm it doesn't work? Below is

1.2.4 does indeed always use the form name instead of possibly using the 
action mapping name, check out bugzilla report:
http://issues.apache.org/bugzilla/show_bug.cgi?id=29796
for the bug and reasoning behind the patch.

I coded/tested the patch for that, and it worked fine for me then. I 
also use it on some test sites, and it was working fine for me the last 
time I used it there a week or so ago.

Is it possible we can see the generated html form tag, as well as the 
form bean definition and validator xml definition? I think it would help 
in solving this. Also, a description of exactly what you are seeing 
error wise (and even in your alert) would be helpful.

One other thing to check, I think name="myForm" has to be type of

RE: how to replace return in a string while use nested:write and bean:write

[Shen, Lei]

Thanks for your hint.

Essentially I want nest:write and bean:write to smart enough to
convert "ab
c" to "ab\nc" byitself.

nest:write is already be able to convert < to < if you set filter=true.
I am trying to find something similar to convert real return to \n.
I am hoping the convertion list is configurable somewhere.

I myself don't see that "the view has been done" but don't mind to be

This is a bit like jarkara logging. There is logging that comes w/ JDK, 
but people try it and go back to jakarta's logging. This has been 
happing for years and is corporate standard practice.

As far as "application controller", in my world of RiA, say Swing MVC 
Application, my scratch for "Struts" is a disptacher to service request 
coming from JDNC applications. Even w/ "appliction controller" in 
"Swing" I still have a use for Struts.

Jumping ahead, JSF markets well, but even if there was no Struts I do 
not think it's production penetration would be high relative to 
alternatives, but I could be wrong.

[Niall Pemberton]

I'm using TortoiseSVN - which is really straight forward for any one in a
windoze environment (expecially if you've used TortoiseCVS!):

Its available here:

http://tortoisesvn.tigris.org/

Once you install it theres a pretty reasonable help file to guide your
through the basics

Re: [OT] Re: A new paradigm of Struts development

[Erik Weber]

First, thanks Vic for your feedback.
Second, right after I posted, I felt like I might have come across as 
insulting to people on this list with my web apps/browsers remark, 
especially considering that this IS a Struts list. I apologize if I 
offended anyone. I don't mean to undermine people's hard work. I agree 
with some of your points here, and I'll say it again, I do like Struts 
and have from the start. But I long to break free of the constraints of 
the browsers in doing interfaces. And in my opinion JavaScript should 
have become much more than it is by now -- it should be doing to/with IE 
and Netscape/Mozilla the types of things that JDNC can do as a baby.

I consider Struts to be a fine example of design patterns, refactorings, 
best practices, etc., put to good use, but it is not more than that. 
Struts to me didn't try to be more than it needed to be. It simply 
abstracted the 10-30% of what 90% of us (doing web apps) kept doing 
repeatedly but in different ways. The fact still remains that HTML-based 
applications are fundamentally flawed. HTML (and HTTP) were not designed 
with today's application requirements in mind. We are still just 
piggybacking applications on the Web, or with better designs, adapting 
them to the Web, which was designed for document (not logic) exchange. I 
hope for better architectures in layers 5, 6 and 7 (and who knows, maybe 
in the lower layers) in the future that, combined with better and better 
load balancing techniques, will change the landscape and how we think 
about Internet applications (in simpler terms, Internet doesn't have to 
equal Web). For example, imagine "browsing a page" that integrates 
stateful, stateless and streaming connection-based technologies like 
marked-up content rendering, instant messaging, multicast updates and 
streaming file exchanges. Maybe it also supports protocols better suited 
to proprietary LANs at the same time. Who wants to make the interfaces 
to all that happen in a proprietary Web browser? Maybe I'm too idealistic.

I think you and I are actually thinking along the same lines. I've been 
working on my own (albeit simple) "browsers" for a while. It's extremely 
rewarding. The application I'm currently spending most of my time on is 
a Swing client that is backed by a messaging server and (Servlet-based) 
applications running on an application server -- very similar to what 
you are suggesting. It doesn't forsake web apps, it just tries to 
forsake the limitations of the Web.

The web interface lacks consistency across browsers and (simple) rich gui

lets face it, rich, clever apps need a gui event model.
I have been toying with the idea of an alternative browser - an application
browser which is used to launch remote applications instead of an html
browser.
Basically you have a browser which is designed to display GUI components
(including custom gui components).  User interfaces are specified (xml, or
similar) and it loads them and displays them.  It then processes events, and
events can either be handled locally through a scripting language, or
remotely through an event in the application code.  The application code
itself is running on a server.  Applications are mainly event->action
driven.  Applications have read/write access the user interface.  As a
developer you just code the app and declare the gui.  The user uses a
standard bit of software to access the app.

Vic, why we would want to continue to write apps for Internet Explorer

I think it is actually the source path of the *debug* configuration you are

I just spent a good 20 minutes figuring this out - I've just upgraded to

Re: The Future of Struts Validation

[Hubert Rabago]

It's not entirely unusual to see posts on the dev list that belong to
the user list.  This seems to be one of the few that go the other way.
Aside from posting this on the dev list, you can also post this idea
on Bugzilla as an enhancement request.  (Some would say post on
bugzilla first then initiate a discussion on the dev list.)  From
there, you can [optionally] attach patches that implement your ideas
and pray that the committers like your idea/patch enough to commit it
to the core and maintain and support it.

Re: Struts app to be passed a parameter (of some kind)

[John Vincent]

I am rather confused here.

application.xml

 
  Abc 
  abc
   
 
  warapp 
  jv1
 
  


allows only one context root.

web.xml


action
org.apache.struts.action.ActionServlet
. 
  

  
action
*.do
  

gives nothing.

I do not see how I can set multiple URLs for the same Struts app.

Why not just configure your servlet container to treat both context
paths as the same app?  For example, in Tomcat, you can create two
 elements with different paths but the same document base
directory.

The request.getContextPath() method would tell your application which
way it was invoked.

So it's just Swing much improved.

I'm not even sure if I should bring up the question of security. Suppose 
I have a custom file chooser. Will there be a sandbox concept like that

Security:
You kind of have to sign the jars and then it pops up a user box "do you 
accept this ssl?" the 1st time user sees you "page".
This is the weakest point of this "arcitevture".

Applets:
The benefit IMO is that it allows you to use the internet for good 
things (like JNLP networkLauch and update)
but allows you to "BYPASS THE BROWSER" so you do not have 2 sets of 
windowing api, etc.

Ex:

If you want to trace through the struts source code, you must link the 
struts.jar to the src code directory in the project's build config 
dialog by right clicking on the jar in the list and selecting properties.

Note that there are cases where you really do want multiple buttons to
invoke the same action.  For example, I'm writing this reply using
GMail, which has a Send button at the top and the bottom of the
textarea that I'm typing in.  Both do the same thing, so they would
both be mapped (if GMail were written using JSF) into the same action
method.
 

I think page-driven development frameworks would exacerbate this problem
unless they clarify with eloquence up-front how to make a clear
seperation of the POST processing from the page preparation required for
the next page.
   

Yep, that is definitely a key point.  Here is why Shale's view
controller helps you do that.  The key point is this:
 The initialization code for any page (no matter how you got there)
 goes in the prepare() method of the corresponding ViewController.
The only thing you should do in the action method for processing a
request is to perform the necessary business transaction (save a
record to the database or whatever), then return the outcome code used
for navigation.  The next page is responsible for taking care of
itself.
Simple enough?
 

Otherwise the uninitiated are always going to write brittle,
hard-to-maintain, hard-to-extend apps.
What I want to see in the future for big apps is a DTD or xml schema

You can already edit JSF-including JSP pages in any editor that
understands JSP syntax, but doing so misses out on the extra benefits
you can get from an editor that knows it is editing components.  For
example, Sun Java Studio Creator (the product I'm architect for) knows
you are working with JSF components, and calls the actual renderers at
design time in order to get faithful WSYWIG.  Plus, it has lots of
special design time behavior that makes the developer more productive.
 

If JSF provides some view components that will output decent table-less
XHTML, then I'll jump at it.
   

Feel free to write a few.  That's what JSF is for :-).

[OT] Re: A new paradigm of Struts development

[Erik Weber]

Vic, why we would want to continue to write apps for Internet Explorer 
and Netscape after discovering a technology like this is beyond me. My 
chips are in with you. I have been pushing my web-app minded clients 
toward Swing all along, but technologies like Java Web Start and now 
JDNC are really going to strengthen my case.

I have a question for you. Sorry if the answer is obvious and I just 
haven't read enough.

I have invested a lot in writing custom UI classes, custom paint 
methods, custom UI defaults properties, etc., to get my Swing components 
looking the way I want (I'm sorry but, changing the background colors, 
and other easily-scriptable stuff, doesn't cure Swing's out-of-the-box 
ugliness). Also, I am amassing a collection of custom components, such 
as self-validating forms and custom JTextPane-based browsers.

In fact, one of my browsers builds layouts based on my own metalanguage 
(soon to be XML). It embeds diagrams with captions and draws arrows from 
the captions to the diagrams based on simple coordinates, etc. Seems 
like I was doing JDNC without even really knowing about JDNC. ;)

I do not intend to abandon my current set of GUI devices, but obviously 
I would like to leverage JDNC if it's worth it, not to mention provide 
compatibility. Will JDNC support my own look and feel (or pseudo look 
and feel)? Can it be easily modified to work with my custom components?

I'm not even sure if I should bring up the question of security. Suppose 
I have a custom file chooser. Will there be a sandbox concept like that 
of Applets?

Thanks,
Erik

No, I don't think so.  JSF is primarily focused on the view.  Struts
is only partially focused on the view.  I think it's plausible that
they could cooperate, even though I haven't yet decided that that's
the best way forward.  As noted above, I suspect that trying to use
JSF as a complete controller solution would lead to the same kinds of
problems people had in "Model 1" (JSP-centered) development.
 

I may have misunderstood, and I am at a disadvantage because I am
still trying to get a good idea of what JSF is all about, but I
thought that Craig saw any merger between Struts and JSF as a
temporary thing which was fundamentally not a long run arrangement.
   

That's a little too simplistic to represent my opinions.  There are
two fundamentally different worlds to consider -- the thousands of
applications already built on top of Struts, and the thousands of
applications that will be written in the next few years (and are
looking for technologies and architectures to base themselves on).
For existing apps, Struts has always embraced new technologies (see
how JSTL, and in particular the expression language from JSTL 1.0, has
been incorporated).  The basic idea has been to allow existing apps to
incorporate these new technologies, *without* throwing away anything
they've already built.  Indeed, this approach has been one of the
reasons Struts is so popular.  Supporting JSF *just* for its visual
components (in the struts-faces integration library) is no different. 
It would be *irresponsible* for the Struts developers not to embrace
this, and allow existing apps to take advantage of the new generation
of visual components that is emerging, without making you throw away
your Action and ActionForm classes, your client side validation, your
Tiles, and so on.

That being said, there is significant overlap in functionality between
JSF and Struts 1.x -- so much so that it is pretty difficult to
contemplate using the combination in new apps.  For example, which
technology are you going to use for validations?  for page navigation?
Quite frankly, if you don't need the validator framework or tiles
there isn't a tremendous amount of value add in trying to combine the
two technologies (and the MyFaces folks have even removed Tiles from
that equation, because they integrate with it directly).
Struts needs to do something useful in the *application controller*
tier ... the view has been done.
 

This is very well said. Using MyFaces and its tiles integration, the 
need of struts 1.x seems to be redundant.

Struts-shale adds value on top of current technologies with its 
framework of request processing and addresses, in a framework fashion, 
application and dialog controllers. Combining this with IoC framework 
such as Spring, we will have a very clean elegant web application 
framework to work on:
   1) The application is completely configurable with faces-config and 
IoC-config. There is no need of digester and writing your own codes to 
instantiate the beans.
   2) We can separate beans for UI components in faces from 
value-holding objects in IoC contaier and programmatically wire them 
together in a very clean fashion using facilities of underlying frameworks.
   3) One valuable feature that shale can address in a framework 
fashion is a standard way of incremental authentication (challenge) when 
specified by the requested resource.

I don't think that this note by "Vinny" is unimportant.  I like the
idea of something like JSF for the view.  I am not sure I like the
controller architecture which it uses and which, i think, ultimately
is a choice inconsistent with Struts, which I like.
   

Personally, I agree that using JSF simply because it will be
including in J2EE 1.5 (or 5.0) isn't reason enough.  But can you
elaborate on *why* you don't like the controller architecture that
JSF uses, and why it's inconsistent with Struts?
 

I don't understand your idea of a "view controller", Joe.  The "view
controller" is a controller which is not something different from the
Struts "controller" is it?  The controller, from my perspective needs
to be decoupled from the view.  A "view controller" is just another
way of saying, if I understand, that the view and the controller will
be coupled.
   

That's exactly right.  For background, go grab a copy of the "Core
J2EE Patterns" book, and look up the "View Helper" pattern.  That is
exactly what a view controller is doing.  There's one view controller
per page.
 

Ultimately, of course, there has to be some interface between the view
and the controller.  I would wish there were an interface that

Override default locale per application

[Chris Searle]

Struts 1.2.4 - running under jboss 3.2

The localization works just fine - if the user has set preferred
languages in the browser.

However - if this is not set the application will use the default
locale of the VM.

This seems to mean (under jboss where the vm is shared amongst apps
AFAIK) that all apps must have the same default locale inherited from
the system - which is a problem here where we need one app to have
English and one to have Norwegian as default:

App 1 has

  app1.properties (which has english text)
  app1_no.properties

App 2 has

  app2.properties (which has norwegian text)
  app2_en.properties
  app2_no.properties

So - if the system locale is english then jboss inherits english and
app2 will use app2_en.properties if nothing is sent from the browser
instead of app2.properties.

I can't see a way to set default locale per application in the config
- is there one?

If not - how would you approach the problem - some kind of override of
one of the struts classes? Would appreciate some hints on what path to
take here :-)

Re: SV: Pre-populate form

[Jeff Beal]

The framework handles it.  Here's a rough sequence of events:
  1) The Struts servlet receives a request for /newinsurance.do
  2) The request processor consults the mapping information and sees 
that there should be an InsuranceBean instance in the request
  3) It checks the standard request attribute for the action form, sees 
that it is empty, and creates a new instance of the InsuranceForm bean, 
*then saves it to the request scope*
  4) The AddInsuranceAction.execute method is called with a reference 
to this newly created bean
  5) AddInsuranceAction sets attributes in this bean (Since Java 
objects are always passed by reference, those values are saved in the 
request-scope -- without any additional developer interaction.)
  6) The request is forwarded to newinsurance.jsp
  7) The Struts HTML tags in newinsurance.jsp look for a request-scoped 
InsuranceBean, and find the one that was created above.  (If there was 
nothing there, they would be responsible for creating a new form.)

HTH, and I hope, also, that it is correct.  I have done this, and I know 
that it works, but I may be a bit off in my explanation.  I don't think 
I am, though.

Why not just configure your servlet container to treat both context

The request.getContextPath() method would tell your application which

Much of JSTL is clearly about view tier stuff -- things like
conditionals and looping to dynamically include or repeat elements,
are totally related to dynamically creating the markup.  The same
thing can be said of things like the XML manipulation, if you're doing
things like user-specific stylesheet transformations and the like.

Other parts of JSTL (such as the SQL tags) are designed for model 1
style programs, and are not really as directly useful in an MVC style
design.

> Or, the better question, why does struts support EL nowadays, when it
> breaks the paradigm?

The way that Struts supports EL is as a *binding* between view tier
things (the custom tags that are creating the dynamic markup) and the
model tier things (your DAOs or VOs or whatever containing the model
data).  You have to have a binding somewhere ... my experience is that
using binding expressions is the most concise way to say things, and
puts the decision in the hands of the appropriate person (the page
author knows that she is creating the "name" field, and therefore
knows what to bind to.

Interestingly, JSTL's expressions are primarily about "pull" of data
from the model.  JSF, which uses essentially the same paradigm for
binding, also uses the expression to "push" data (after any needed
conversion and validation) back to the model.  Therefore, an
expression like:

  

is used at two different times:

* When the page is rendered, pull the data from the customer bean
  (doing any necessary conversions on the way).

* When the form is submitted, and after any conversions and validations
  have been performed successfully, push the data back to the model.

This binding activity plays pretty much the same role that ActionForm
beans do in Struts, but without the need for an extra class.

easily editable by my editor of choice, using syntax-highlighting to 
show me where my XHTML is up the swanny.


Just in case you missed my posts about a great Sun open source project 
JDNC that will be a part of J26 Standard Edition (Mustang), it does 
above, one of the reasons that I am "raving" about it, check it out:

http://javadesktop.org/jdnc/0_5/docs/tutorial/index.html
And I am using it w/ a lot of success. Right now I am just doing the 
"Swing" extensions, but will tie in UI via XML (and will add code to 
make it work w/ Hessian SoA, it's trivial binding).

My chips are behind JDNC.

How to change Tiles's tab?

[PC Leung]

For a page or summary tab, a tab is a label of words.
Can I change it to an image file?
If not, can I add an image file?

Moreover,
there is a purple border after clicking a tab.
Can I change the border color and even remove it?

Thanks

SV: Pre-populate form

[Roland Carlsson]

Hi Jeff!

When you say that the newinsurance.jsp "just see it" where do you store
"it"? In request.setAttribute() with some key? Session?

I'm using DynaValidatorBean but I guess that it should work in a simular
way.

Thanks in advance

Struts app to be passed a parameter (of some kind)

[John Vincent]

 Need one Struts app, but must have multiple URLs.
 
Thus
http://www.jv.com/company1
http://www.jv.com/company2
 
actually start the same Struts app, say
 
http://www.jv.com/myApp
 
but must "pass" something into the Struts app so that it knows who, or 
rather, which URL invoked it.
 
Thoughts:

Write a servlet, handles multiple URLs, init-param set to a unique value 
for each servlet. 
Add a header into the http response object before issuing the redirect.
Redirect to the Struts app.

Where in a Struts app can I pick up the header (or other)?

The Struts app, in web.xml, has a welcome file of logon.jsp. Could I get 
the header here? Doesn't seem to work. 

Any ideas?

Re: Pre-populate form

[Jeff Beal]

Every JSP page in my application is going to have two actions associated 
with it.  One action will always be called prior to displaying the JSP 
page.  The other will be called to process the user's input.  In the 
struts-config, both of these actions are configured with the same form 
bean.  Thus, when Action 1 is called, it has an instance of the 
ActionForm and that instance is already in the appropriate scope, etc. 
All I have to do is populate the values and the JSP page can display them.

struts-config.xml:

  
  



In my AddInsuranceAction, I can populate the InsuranceBean with 
information from the database and the newinsurance.jsp will "just see it".

Re: Indexed Properties, checkbox

[Rafael Cardoso]

I might be missunderstood your idea, but here you start navigate with JSP and then go to 
the Action "/DisplayNestedPropertiesAction.do". You can set your checkbox in 
two ways:
if you need to set up all checkboxes to false (or true, or fixed values) on the initialization of the ActionForm, you should use the reset() method of the actionForm.
if you need to set up checkboxes with other "non-fixed" values, you will need to create one action before to set up the ActionForm. In that Action you should instantiate your actionForm, and then populate your property of the checkboxes and then you ActionFoward to the JSP. 

I Hope it helps...

Okay submitting a form perhaps not, but having a mechanism where
outputLink or something can call an action/action listener. As things
are there is no provision to be able to simply generate a simple
navigation bar/list of links.

Perhaps allowing commandLink outside a form would, that renders
differently could be one idea. So when  it would render a link. How that link
would render to call the target method in the backing bean I'm not
certain.

The link is still a command. Despite disliking the javascript, I was
prepared to live with it. But there's little I can do if it doesn't
work.

I hope JSF does come through, but as a user I've been stung badly and
as a result less brave in my choices of technology adoption. I didn't
touch JSF for 1.0 to avoid any bleeding edge problems, waited until
1.1 figured I'd live with multipart forms not being supported. But
still ended up getting cut.

SV: Pre-populate form

[Roland Carlsson]

Hi Mark!

I belive that there must be a simpler solution to this. I know that I can
creata a DynaActionForm and then pupulate that by calling the set-method. So
shouldn't it be possible to create a DynaActionForm in a "populateAction"
and then put it into a "scope" with a key and then forward to the
(html)form?

Thanks in advance
Roland Carlsson

the checkbox property in the reset method; how can I do this in my actionForm

with the indexProperties?

3.) How can I get only the checked Bean in my action. 

When I select a checkbox, I would like to trigger an action (/ViewTheSkill.do). 
How can I get (ONLY) the corresponding bean in my action? 
ViewTheSkill.execute(). I would like to use this bean for further processing.

public class ViewTheSkillAction extends Action{

public ActionForward execute(ActionMapping arg0, 

ActionForm arg1, 

HttpServletRequest arg2, 

HttpServletResponse arg3) throws Exception {

NestedPropertiesForm nestedPropertiesForm = (NestedPropertiesForm)arg1; 

//HOW CAN I get the checked SkillBean here?

}

RE: Validator - Redirects or Forwards?

It uses forward (otherwise the errors get lost between requests!).

Do you get an error?

indexed property and checkbox (may be newbye question)

[Ryan julius]

Hi, 

I have investigated the indexed properties as follows.

public void setSkills(List skills) {

this.skills = skills;

}



/**

*/

public SkillBean getSkills(int index) {

// automatically grow List size

while (index >= skills.size()) {

skills.add(new SkillBean());

}

return (SkillBean)skills.get(index);

}



public void reset(ActionMapping actionMapping, HttpServletRequest 
httpServletRequest) {

//I would like to initialize the checkbox properties here to false...

}



public void init(){

skills = new ArrayList();

}

}

embeded Bean:

**

public class SkillBean {

The Future of Struts Validation

[William Ferguson]

Now that I've had a year or so or heavy Struts use, I've come to believe that 
(IMHO) validation within Struts is a little less clear and concise than it 
could otherwise be with a few small changes.

Currently, validation is defined by specifying a true/false value for the 
'validate' attribute for an ActionMapping, and which validation to perform is 
defined by either the ActionMapping's (Form) 'name' or 'path' attribute 
depending on whether the Form extends from ValidatorActionForm or not.

It seems to me that it would be clearer to introduce a 'validation' attribute 
into ActionMapping which defines the Id of the validation (if any) to perform. 
This would supercede the 'validate' attribute and removes the responsibility of 
identifying the validation target from the combination of the (Form) 'name' 
attribute and the ActionForm inheritance hierarchy.

It also allows all the benefits of using (currently) using a 
ValidatorActionForm to validate based on ActionMapping path, plus those of 
using Form named mappings, while also allowing the freedom to mix, match and 
reuse validations across ActionMappings.

It should be easy to make this new addition entirely backward compatible. Ie If 
'validation' attribute is not found then look for current attributes and follow 
the existing validation path, at least for some deprecation period.

Once this refactoring has been achieved, it also opens up the possibility of 
further enhancing the existing validation mechanism. Ie Allowing validations to 
contain other validations etc. Though I would first start by simplifying the 
validation definitions, which I also find somewhat non-intuitive at times.

Anyway, just my 2 cents.
I'd like to thank the Struts development community for a pretty decent 
framework, especially those worked on Tiles - it really rocks!

William Ferguson

RE: Pre-populate form

[Mark Benussi]

Roland,
I dont know if this solution is not the approved way but I do the following.
I have a CreateForm which extends the ActionForm. It contains all the 
properties that map to the database and the validation rules.

I then have an UpdateForm which extends the CreateForm and implements its 
parents validate (If required). It can also hold data above the CreateForm 
such as the key of the data being updated

When I want to update the data I call an action which does the following.
BeginUpdateData
Retrieves the data to be updated.
Generates an UpdateForm that represents the data.
Place in the session.
Then in the UpdateForm reset method.
I pull the UpdateForm from the session and popluate the data from itself (If 
that makes sense).

Then you can use the same pages pretty much to updated the data as it will 
be prepoluted and you also have a handle on the data you are updating.

Re: A new paradigm of Struts development

[Adam Hardy]

A lightweight framework must be simple to implement, for RAD or for 
prototyping or for web newbies. Given a large complicated application, 
should an architect choose a lightweight framework? No. She / he must 
recognise the limitations of the framework.

JSF seems to be lightweight. It simplifies and speeds up development. So 
what limitations does it have? I don't know JSF (I must download it (and 
shale)), but it sounds like you've sacrificed the ability to deal with 
multiple Command scenarios (submit buttons) on a robust controller.

The last page I saw on my previous project had 10 submit buttons. What I 
see is developers writing monolithic tracts of code in their Action 
classes to handle all Commands at once. E.g. a search page with search 
again, back, fwd, begin, end etc.

I think page-driven development frameworks would exacerbate this problem 
unless they clarify with eloquence up-front how to make a clear 
seperation of the POST processing from the page preparation required for 
the next page.

Otherwise the uninitiated are always going to write brittle, 
hard-to-maintain, hard-to-extend apps.

What I want to see in the future for big apps is a DTD or xml schema 
that brings JSP code and XHTML mark-up under control. Something that is 
easily editable by my editor of choice, using syntax-highlighting to 
show me where my XHTML is up the swanny.

If JSF provides some view components that will output decent table-less 
XHTML, then I'll jump at it.

And what about database access tags?

It's the same thing, why there are no pointers in java (besides that it's 
meanwhile impossible because of the gc): give the user something which can be 
misused, and he will.

I don't think EL breaks the MVC pattern. Although it leaves you free
to do so if you so wish. I don't see a world appart from using







${person.name}

More to he point the fmt tag lib put the presentation control back in
the hands of the site builder. Otherwise you end up addressing view

How to iterate neseted beans?

[sebastian . steinfeld]

Hi,

I want to iterate through a nested bean, it is 3D.

The first bean contains an ArrayList, of the second bean. 
Each second bean contains an ArrayList of the third bean.
Each Third bean contains different attributes.

I want to print Attributes of the third bean in text-field and the user
should edit them 
and committ changes by pushing the submit-button.

I can call the getter of the attributes in the third bean, but how can I
make the
application call the setter?


This is my code... what should I do?

Using non struts-config.xml MessageResource in the Validator

[Christian Bjørnbak]

Hi
I'm currently migrating a system from some homemade XML framework to Struts.
The system is an application service provider where lots of companies 
have the own db driven ResourceBundle for i18n.

All the companies use the same struts-config.xml as they all share the 
same Actions, Forms and jsps, and servlet's PathInfo decide which 
company's pages is requested..

The i18n for the texts on the pages is solved by extending the JSTL 
messageTag to use our own ResourceBundle.

Now the problem is the texts used at validation of errors...
I would like to be able to use the Struts Validator, but how do I tell 
the Validator to use a custom ResourceBundle/MessageResource instead of 
the one from struts-config.xml??

I've figured that extending the ValidatorPlugin is the entrence, but I 
can't find where the errors converted to texts..

Any pointers??
