After another evening of flailing, I managed to make this work in a 
rather inelegant way:

In "myPageTemplate.jsp", I added this tag:



and I changed "myBodyImpl.jsp" to say:

foo = <%= request.getAttribute("foo") %>

This works, but I'mnot very happy with it.  Does anyone have a better 
solution?

Basic Code for Indexed Properties

Dear Anurag,

I have pasted the basic code that you need in the JSP, 
Form and Bean class to implement indexed properties.

This will show a page with dynamic number of textboxes and
For each textbox, it will get/set the particular property
within your collection of beans that is inside your form.

HTH,

Form Class

public ArrayList getIndexedBeans() {
  return this.myBeans;
}

// THIS METHOD IS REQUIRED IF YOUR FORM IS OF REQUEST SCOPE.
public MyBean getIndexedBeans(int index) {

  while (this.myBeans.size() < index) 
this.myBeans.add(new MyBean());

  return (MyBean) this.myBeans.get(index);
}

Multibox over a collection

2003-07-08 Thread Sussu Struts

Hello,
 
I have read thru the archives on this topic and want to know is there a way of using 
multibox over a collection . All that every one put as example is from Ted's tip , 
which uses a string buffer(which has item as string array etc etc)
My problem is that I have a table in which every row is a object of a formbean and has 
checkbox on the left which is a column of the table. So every row of the table has a 
checkbox. Iam populating the table using the iterate tag over a Arraylist. Now problem 
is getting the row which a user select back in action class for further processing.
 
pls. help and thanks in advance
 
Thanks 
Sushil 
 
PS:- Btw I read in one of the mail that Struts doesnot support multibox over 
collection and work only against a arrayis it true!!!

Design question: Confirm action after validation ?

2003-07-08 Thread Ajay Patil

Hello,

In my Struts application, the validation is done on server-side 
for every page. If the validation is successful, the user would
like to see a page to confirm his action. The Confirm page should
also have a Cancel button allowing him to go back to the previous
page showing the data entered so far.

This functionality is needed for every action.

I am thinking if there is a generic way by which I can achieve this
functionality. 

I also realize that I might end up making scope=session for
every form, in trying to implement this requirement. (and I am
worried about this too).

Any ideas, pointers and/or thoughts will be very useful.

NestedIterateTag won't let go of collection

2003-07-08 Thread Sri Sankaran

Using: Struts 1.1
Servlet Container: Tomcat 4.1.24

In the process of studying the memory footprint of my application, I found that 
certain objects were not getting garbage collected even though there were no apparent 
references.  The biggest culprit was a rather large collection that was being 
displayed using .  

I am mentioning *how* it is being displayed only because JProbe revealed that the 
reason the collection isn't getting free'd is because the associated NestedIterateTag 
object was maintaining a reference to it - even after the user session was 
invalidated.  

I realize that this may not be Struts-issue per se but one of how Tomcat manages 
(reuses) tags.  Have you seen such behavior and is there a way to coerce tag to free 
the application object?

Thanks

Two questions (MySQL Pooling and ActionForm)

2003-07-08 Thread Ali . Naddaf

Hello everyone.
I am new to struts. I have the following two questions:

(1) About MySQL DataSource Pooling: I have set up my struts-config.xml 
like the following:

   
 
 
 
 
 
 
 
 
   
 
and I am using "mysql-connector-java-3.0.8-stable-bin.jar" driver. All is 
good and I can access my pool but when I leave my application overnight, 
the next morning I get an exception, when it wants to use the pool. The 
README file coming with the above driver says that the "stale" connections 
die after 8 hours and suggested to add the attribute "autoReconnect=true" which I did 
but am still getting the same result. Does anyone have any 
suggestion? 

(2) I have an ActionForm which has a checkbox. This checkbox is supposed 
to reflect the state of a boolean attribute in a certain database. I have 
an "student" instance (of a class Student)which is saved to the session 
and student.getStatus() returns the current state. Anyhow, what I want to 
do is the following: when I access the JSP page  which is associated with 
that ActionForm true the form-tag action, I want the checkbox to show the 
status based on the student.getStatus(). At the same time, when I toggle 
the checkbox, and click on submit, I want the database to be updated. The 
problem that I see is that 
(a) If I use the reset(...) method of the ActionForm to say something 
like:
this.status = ((Student) 
request.getSession().getAttribute("student")).getStatus();
then on opening the jsp page for the first time, I get the correct state 
for my checkbox but when I toggle that and submit, it doesn't really 
accept my new state
(b) On the other hand, if in that reset() method, I simply say:
this.status = false;
then the first time I access the page, it is always unchecked but toggling 
that and submitting the form does update the database.

So what is the proper way of doing this? My ActionForm is different from 
my "entity" (i.e. "student") since they had many stuff which were not 
common between them.

Any help is greatly appreciated.
Thanks,
Ali.

Converting an ActionError to a string programmatically

2003-07-08 Thread Kornelis Sietsma

Hi all.

I am looking for a good way to turn an ActionError into a string, without having a
PageContext or anything else so useful (so I can't use the RequestUtils.message()
function).

Is there a simple way to do this?  I can probably do it the hard way, by digging
through the RequestUtils source and working out what it does, but I'm hoping that
either (a) there is another utility class I've missed that will do this, or (b)
someone else has done this and can save me the pain!

The reason I need this is that I have some code that updates a back-end system, and
returns ActionErrors if there are any validation failures.  Usually this gets called
from a struts action, and the errors get displayed to the user with the 
tag.

However, now we need to do some background batch updates, called from a thread
spawned from a servlet (which is outside our normal struts pages).  The batch process
is likely to be slow, and so we want the results of any validation failures to get
logged to an error file, rather than getting displayed to the user.

Any suggestions?

Accessing Application properties from business classes.

2003-07-08 Thread Zoran Avtarovski

Hi guys,

I know I've asked this before but I'm after some clarity. I have a web
application which gets deployed on a number of different systems and each
one has different settings with respect to file locations and email server
settings.  I'd like to set the mail server and directory settings in the
application.properties file (one central location, automatically picked up
by the app, etc).

I need a way to easily access the file from business classes. At the moment
I am using a couple of different workarounds: getting the settings in the
action file and then passing the appropriate values to business methods, or
passing the request object to the business methods, neither of which seem
very efficient.

I'd like to know if there is a way of retrieving the values in a simpler
fashion, using the application object for example.

As always any input always appreciated.

Zoran

Re: Tag inside a tag


Is it a limitation of HTML or struts tag implementation?
Does struts 1.1 solve this issue (JSTL or otherwise).

Re: How can I set the defualt selection?

2003-07-08 Thread leonZ

example.jsp code segment:
...


1
2
3

...

Don't forget adding the set and get method for submit_flag to the
exampleForm.java

exampleAction.java code segment:
...
public ActionForward perform(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) {
MessageResources messages = getResources();
Locale locale = getLocale(httpServletRequest);
String flag =
httpServletRequest.getParameter("submit_flag")==null?"":httpServletRequest.g
etParameter("submit_flag");
if(flag.equals("")){
( (exampleForm) actionForm).setType("2");  /** set the defualt
selection **/
return (new ActionForward(actionMapping.getInput()));   /**
here the example.jsp will be show  **/
}
..
...
}

and you have to visit the exampleAction(something like exampleAction.do)
instead of example.jsp for the webpage view.

that's my solution, I hope it will be helpful.

Re: ClassCastException using the DynaValidatorForm

That would explain it.  The struts-config got re-loaded telling it that 
"myForm" was a dyna bean, but the re-serialized bean in the session was 
still one of my custom beans.

Thank you!  I had no idea that Tomcat serialized the session data when 
it shut down.

Did you also close the browser window you were using to test?  IIRC, Tomcat
serializes session data when you shut it down.  Just a guess, but I think
you had a session sitting around with the "old" form bean, and since the
name was the same, it got used.  If you had changed the name from the
beginning (myForm2) you likely never would have seen this.

Specify Error Messages For Automatic Validation

2003-07-08 Thread Caroline Jen

I am trying to put entries in the
MessageResource.properties file for the error messages
generated by the automatic validation. 

I used "mask" to provide a number of validation rules.

How do I specify those error messages?  (I used "mask"
for a number of text field to report various errors.) 
I would like to see an example.

I could find examples for email and date:
errors.email={0} is an invalid e-mail address.
errors.date={0} is not a date.

Re: PAC pattern (Presentation-Abstraction-Controller)

2003-07-08 Thread Carlos Duque

Methinks you're basing your assumption upon the original MVC model for 
GUIs.  Here is the Sun version, and it does talk of PAC as a related 
pattern, but you'll find, I think, that it's splitting hairs.

Are you sure? I've read papers published by the author

PAC has a controller between the abstraction and the

abstraction (Model). I think that conceptually they
are different.
What do you think?

Re: ClassCastException using the DynaValidatorForm

originally, i had a custom form bean with the name "myForm" and an 
action with the same name.

i set up validation, and all was well.  my form has oodles of fields, 
however, so i figured i could save myself a load of development and 
maintenance by using the dyna-form beans.

so, i created another form bean (a DynaValidatorForm) in my 
struts-config. i named it "myForm", and re-named the old "myForm" to be 
"foo" so that i wouldn't have two forms with the same name.

this resulted in the ClassCastException i described earlier, despite 
reloading the webapp and even restarting tomcat.

so i switched and renamed the dyna-bean "foo" and the custom form bean 
"myForm".  things started working again.

THEN, i changed the name of the form bean used by the action to "foo" 
(which is now the name of the dynamic from bean).  to my surprise, that 
works!  and that's where i am now.  functional, but confused.

i can hear the PHP guys snickering.  :(

The two reasons are legitimate in general. I am not against to them,
here just to provide some *fresh* ideas in our practices:

When we consider the action mappings and the compiled action and
form bean classes as ONE thing, we do have the above concerns.
However, when we consider the action mappings and corresponding
JSP pages as ONE thing, we have some opportunities to advance:
Modifying a configuration term in an action mapping could be made
equivalent to modifying a JSP page, because both of them assume the
compiled classes are not changed. So a tool could remove
JSP pages and action mappings and then add them back as needed.

This is our idea to manage large number of JSP pages and action
mappings. We put a flag in an application module which indicates the
module should be frozen or not after initialization. If a module is
not frozen (managed by administrators), designers could publish
new action mappings with the corresponding JSP pages or
withdraw them as needed. Action mapping themselves are
always frozen. Of course, such organization will open holes that
some web forms may not find their action mappings because
they are withdrawn. But those errors are tolerative in many use
cases or can be reduced to miminum if some deployment rules
are implemented. Any other ideas or concerns, I am not very
clear at the moment.

i have discovered that if, instead of renaming the forms, i change

The name in action mapping needs to relate back to a name in the 
form-beans configuration.  So you should be able to change the name, 
as long as you change it in both places.  If you use the "name" 
property in your  JSP tags, you have to change it there 
also, although during the 1.1 development cycle this was changed so 
that the html:form tag would look up the form bean from the mapping 
found with the html:form action attribute.

You shouldn't be stuck with a "foo" form, but you may need to make 
changes in more than one place.

RE: using getInputForward vs new ActionForward(mapping.getInput())

Or, I can just tie the errors into my session object and use my own tags to 
pull and push them as needed (still ugly, but keeps the url clean).

Perhaps there's a struts developer reading this list who has some insight.

Huh.  I am surprised that it worked for you before.

And yes, if you want the URL to change in the address bar, you will need 
some
sort of redirect.  (Correct me if I am wrong here).  However, once you 
redirect
the page, you lose anything that's returned in the response, including the
errors collection.

An ugly hack is to pass the errors in the URL.  But as I said, it's ugly.

I would be interested to know what happened, why it worked before?

RE: (Newbie) html:link passing an object via the request object

2003-07-08 Thread Davidson, Glenn

Further research shows that the link is converted to html which does not
accept objects, only strings. So it looks like I need to pass in a string
that will be used to identify the data I need. I should have an Action to
take the string id from the request object and generate an object with the
data I want and then pass control to the jsp that will display it.

Is this the best way to do this? Is there an easier way?

I could use an object cache to eliminate the need to recreate the objects
each time they are created (the data is static).

Thanks

Re: Session ID always being appended even with cookies enabled?

2003-07-08 Thread JavaXML Developer

What you are seeing is "jsesssionid". The jsessionid is a key maintained by the 
container to track the user session via HTTP. Including the session key in the 
hyperlink is called URL rewriting. The Servlet Specification encourages the use of 
cookies to maintain the session. When that is not possible, URL rewriting is used 
instead. The first time browser makes a request to the container, the container does 
not know whether the browser will accept a cookie. The container can offer the browser 
a cookie, but can't tell if it was accepted until the next time a request is made. 
(HTTP has no "handshaking".) In the meantime, the response for the current request 
must be written. So, the first page written for a browser will always need to use URL 
rewriting. If no subsequent requests the container finds that its cookie was accepted. 
It can skip rewriting the URLs.
 
Hope this answers your question.

chaining struts jsp tags

I have some custom JSP tags that I am using, and I want them to output
text that is this processed by the standard struts tags.  Is this possible?

For instance, I have a custom tag that will output something like:



this is the path   and the image is, etc



and then that would proceed to be parsed by html:rewrite to do the
right thing.

Can this be done?  Thanks!

(Newbie) html:link passing an object via the request object

I need to assign an object to the request object via an html:link

using getInputForward vs new ActionForward(mapping.getInput())

2003-07-08 Thread Adam Levine

My goal in handling "business problems" in validating a form submission from 
an Action.execute() is 2-fold:

1:  Display the accumulated ActionErrors (ie, using [html:errors/] )

2: "Return" the user to the exact same URL in their browser address bar.

I was using an action-mapping forward in struts-config to send them to the 
original .jsp they used to submit from.  The errors were showing up (good), 
but the URL in the address bar was being shown as /dynamic/Path.jspa (bad)

So I changed the action-mapping, setting "redirect" to "true".  Now the 
address bar was correct (good), but the error messages were gone (bad).

Then I did a lot of web searching, and discovered that I should be using the 
getInput.
So, now my execute() was returning:  return new 
ActionForward(mapping.getInput());

This worked!  The address bar was correct and the errors were still present.

Then I "upgraded" my struts library to 1.1b3.Now I'm back to the 
original problem of the address bar being right, but my errors are gone.

I found   mapping.getInputForward(), and tried returning that, even going in 
and setting the redirect field to "true".  I'm bouncing between the same 2 
situations I had before.

Am I missing something?  Is it no longer possible to have "the best of both 
worlds"?  For whatever it may be worth, I'm using the -el sets of libraries 
(thank you for finally getting that!).. and jboss 3.07.. and xdoclet...

Thanks for any insight you can provide.

Re: Best place for security checks in Struts?

2003-07-08 Thread Sloan Seaman

You could have a class that is an Action (say, named SecureAction) and then
have all of the actions in the struts file extend SecureAction and implement
a method called executeSecure() (not execute()!)

What then happens is your action in the Strust config (say, named ShowUser)
gets called by Struts but since it extends SecureAction, Struts calls
SecureAction's execute().  It then checks security and if it's good it calls
executeSecure() which is the method that ShowUser overwrote.

If the security doesn't pass, then SecureAction never calls executeSecure...
and there ya go.

You can then define the security on a per action basis by making your own
ActionMappping object and doing something like:


That is how I did it for a while and it worked great...

Re: Best place for security checks in Struts?

2003-07-08 Thread Sandeep Takhar

This is the requestProcessor.

Sorry for that.  I am busy doing work and then I
answer a question...

The way I think of it is that there is a
requestProcessor for each struts-config.  (You declare
it here).  So if you have multiple modules, you could
theoretically have a different processor for each one.

RE: Login Form

2003-07-08 Thread Erez Efrati

Thanks Sean, 

I looked at it and it does avoid the BIG limitation posed by the
standard spec in fact. Still I cannot use it since it disables the
passing of the principal identity through calls to EJB methods.

Now, I am new to the web development and it amazes me that such a basic
feature is missing from the Servlet spec and is not addressed. Why is it
that way? Is it so unusual to want to have the login fields on the start
page??

Thanks,

Re: Populating select boxes dynamically

2003-07-08 Thread Erik Price

sriram wrote:
James,

As explained by you, I have done the following:

I need list of countries in a drop-down box in .jsp page.

I have an EJB that maps to country table in database.
In that I've a method getAllCountries() that returns a collection.
In that method, I've used LabelValueBean and storing labels and values in the
collection.
I'm using a Session Façade, so this method is called by a session bean which obtains the collection of countries.

Now I would like to know the next step - creating a "pre" action which obtains this
collection and stores it in 'request'.
I've an action form with getter and setter methods for 'countryID' (countryID is the name of my
in the jsp page). But how to create a "pre" action? Can you pl. explain
Create a Filter and map it to any resources that will need the countries
collection. (I think you need to map it to the resource that will be
requested, not the JSP that is forwarded-to -- so, in other words, map
it to the Actions that will need it.)

In this Filter you can make the call to the session facade that gets the
list of countries, and then you can store it into the Request as an
attribute. Later, your Action or JSP can extract this information from
the Request to build the drop-down. If you run into performance
problems, you might want to cache this action either in the Session
Facade itself, or in an application-scoped attribute stored in the
ServletContext. But I'm not sure how often your country list might change.

RE: Dynamically changing forward in ActionForm

2003-07-08 Thread Fedor Smirnoff

Hey,

I think that global forward is the best solution for
it as Neil mentioned. However, I havent tried this yet
but would it be possible to include login check into
lets say GeneralAction that extends Action, and than
every other action will extend GeneralAction. So
basically this action being in the middle can do all
the general processing that will be required by an
application. I read something about it in one fo the
books, and it does sound doable and useful, is it?

Thanks,
Fedor

sslext

I am using Struts 1.0 and Tomcat.  I am trying to use sslext to submit
a form securely.  I just tried it with cookies disabled, and the URL
does not get encoded.

Here is a snippet...


  


When I turn off security (i.e., set the "secure" property for the
corresponding action to "false"), it encodes the URL as I would expect.

To those of you who have used this, am I missing something?

There is an example application that demonstrates how to switch between

Thanks for your reply, Sandeep. From what I have understood from reading the

Re: PAC pattern (Presentation-Abstraction-Controller)

2003-07-08 Thread Dos Santos

Are you sure? I've read papers published by the author
of PAC and she states that they are different.

PAC has a controller between the abstraction and the
interface (presentation). MVC has 2 interfaces (View
and Controller) both of which interact with the
abstraction (Model). I think that conceptually they
are different.

What do you think?

No.

If you really need programmatic login, you will want to look at "roll
your own" security mechanisms instead of container managed security.

One approach would be to provide a login button (instead of a login form)
that goes to a protected resource (triggering the login), and then have
the protected resource forward or redirect back to your main menu.

If you're using Tomcat's JAASRealm (or something like it) for this, this

RE: Best Practice Mapped/Indexed Properties on an ActionForm

2003-07-08 Thread Nate Bowler

Yours and Michael's suggestion are similar and will likely be the approach I
will take. I'll probably just use the ListUtils.lazyList(List, Factory)
decorator to create the autovivifyingList.

What's surprising to me is that this seems like an extremely common use
case, but it isn't clearly mapped out in the Husted book or in the online
docs. I'm sure many developers want to retain an object structure for forms
that contain dynamic lists of data, and using commons-collections lazyList()
would seem like a good documentation example to provide (assuming this
works, of course, as I have not yet implemented it).

At any rate, thanks for the reply.

Nate

-Original Message-
From: Justin Hickman [mailto:[EMAIL PROTECTED]
Sent: Tuesday, July 08, 2003 10:23 AM
To: Struts Users Mailing List
Subject: Re: Best Practice Mapped/Indexed Properties on an ActionForm

Nate,

I ran into that same problem a couple of weeks ago.  The
solution that we came up with was to create an AutovivifyingList
object.

Basically, with the AutovivifyingList object, we have extended
java.util.ArrayList and added functionality to allow for
autovivifying objects.

When struts tries to populate indexed objects from a form, it
will do something like: form.getList(1).setFooBar("value"); It
has a problem when it does "form.getList(1)" because the list
does not exist with any objects in that index.  To avoid this,
we have the overridden method "public Object get(int)" and
instantiated the appropriate object if it didn't exist and would
return it instead of null.

Of course, you would have to have constructors to the
AutovivifyingList object that takes in a class object of the
class you want instantiated on a get, and you would also need to
tell it if you should instantiate intervening objects (for
example, if you do a getList(5) and 1-4 doesn't exist, you can
tell it to create all intervening or leave them null)

That's the basic idea behind it.  Of course there are many ways
to implement it.  This, however, is how we handled the issue of
request scoped indexed forms.

I hope this helps. If you need a more concrete example, let me
know.

Thanks,

"jakarta-commons-sandbox" CVS repository, under package "workflow".  It
hasn't been worked on for a long time, and in truth it would be better to
start over again based on something like Jetty than continue to invent yet
another scripting language written in XML.

Struts 1.1 does not support dynamic reloading of mappings (or any other
config information) for two basic reasons:

* The in-memory data structures are frozen, so they don't need
  to be synchronized when they are read (which happens a LOT).

* Reloading the configuration information is only half the battle --
  you're also going to want to reload recompiled Action and form
  bean classes, and there is absolutely nothing Struts can do to
  help you with that.

You should really be using the application reload facilities of your
servlet container to do this sort of thing.  I typically develop against
Tomcat, and use the custom Ant tasks to dynamically install, reload, and
remove an app while Tomcat is running.

Session vs GET parameters best practice

2003-07-08 Thread José Moreira

Hello, i humbly confess that since my ASP/PHP times, not long ago,i've
been having problems understanding the 'best-practice' of 
Session vs GET parameters in CRUD's...

In my current application the practice i use is the following, for
editing a single PGSQL table:

 * a page displaying an result list with the records ( no paginator for
the time being), where a link like :

 http://localhost:8081/editEvent.do?eventId=2

in each row points to a form where the user can instally manipulate the
data. In this page also there's a link like 

 http://localhost:8081/deleteEvent.do?action=confirmDelete

pointing to an actions that redirects to an 'deleteConfirm.jsp'.

Because of the 'eventId' is being saved in the HTTPSession when the user
enters deleteEvent.do, the delete link doesnt have an &eventId=X ...

In the confirmPage i have 2 links refering to :

Really delete event? 

 http://localhost:8081/deleteEvent.do

 http://localhost:8081/editEvent.do

But because of editEvent.do 'needing' an ?eventId=2 for displaying the 

right record, the page throws an error, that means that 

deleteEvent.do?action=confirmDelete also needs ?eventId=2...

Resuming, it's a big mess, like this e-mail and my confused mind :)

Has anyone has thoughts for me?

thanks in advance ...


Ps.: I've read the manuals :)

Best Practice Packaging Reusable Components

2003-07-08 Thread Frédéric Dreier

Hi,

I try to develop reusable components like login form, locale chooser,
explorer tree, ... and I am looking for a 'nice' way to package such
components (jsp,java,gifs,..) in JAR file.

Or perhaps there is another way to accomplish this?

Single error message for multiple fields using Validator?

2003-07-08 Thread Poon, Johnny

Hi,

I'm using Validator.  Can anyone tell me if there's a way to only show one
general error message when there are errors on several fields on the page?
Further, how to change the font on the title and move focus to of all the
error field?

What I want to do when validation comes back false are these:
1) Show a general message for a type of invalidity, e.g. for required
fields: "Please fill out all of the required fields."
2) Change all the font of the title of the invalid fields.
3) Put the cursor focus on the first error field and have the input
highlighted(selected).

Any help and pointers would be greatly appreciated.

Thanks!

JP

Re: Best Practice Mapped/Indexed Properties on an ActionForm

2003-07-08 Thread Justin Hickman


Nate,

I ran into that same problem a couple of weeks ago.  The
solution that we came up with was to create an AutovivifyingList
object.

Basically, with the AutovivifyingList object, we have extended
java.util.ArrayList and added functionality to allow for
autovivifying objects.

When struts tries to populate indexed objects from a form, it
will do something like: form.getList(1).setFooBar("value"); It
has a problem when it does "form.getList(1)" because the list
does not exist with any objects in that index.  To avoid this,
we have the overridden method "public Object get(int)" and
instantiated the appropriate object if it didn't exist and would
return it instead of null.

Of course, you would have to have constructors to the
AutovivifyingList object that takes in a class object of the
class you want instantiated on a get, and you would also need to
tell it if you should instantiate intervening objects (for
example, if you do a getList(5) and 1-4 doesn't exist, you can
tell it to create all intervening or leave them null)

That's the basic idea behind it.  Of course there are many ways
to implement it.  This, however, is how we handled the issue of
request scoped indexed forms.

I hope this helps. If you need a more concrete example, let me
know.

Thanks,

Overriding the request processor is my favored place.
You could extend action mapping to have additional
security parameters and in your extended request
processor you check if users are allowed to execute
the corresponding action when the roles are not sufficient.

Re: ClassCastException using the DynaValidatorForm

i don't know what's in 'instance', i'm just guessing it's not a DynaBean 
because of the exception i'm getting.

i have discovered that if, instead of renaming the forms, i change the 
name of the form in the action mapping, validation works.

so now i have a form named "foo".  :(

not very elegant.  my php-centric coworkers will mock me.  i'll be the 
laughingstock of the company.

I missed your second post. My mailer didn't thread it. So what is struts

I don't suppose it would be so simple as the wrong form specified in the

Here's the struts source that's throwing the exception:

Apparently, "instance" is not a DynaBean.  It would appear that 
something other than a DynaBean is being stored where struts expects 
to find a DynaBean.

Does this help anyone figure out what I'm doing wrong?

Re: Best Practice, Variable Number Of Form Elements

2003-07-08 Thread Michael Thompson

If you have indexed props with lists of java objects
on your form:
public Person getPerson(int index);
public void setPerson(int index, Person person);
public Collection getPersons();
and you have a  or whatever

then struts(beanutils really?) will do something like

yourFormInstance.getPerson(4).setName(theValue);

What I've done in the past is lazily create person objects in the 
getPerson method

private ArrayList _persons = new ArrayList();

public Person getPerson(int index)
{
   while (index < _people.size())
   _people.add(new Person());
   return _people.get(index);
}
There are other methods for doing this lazy loading.  I'm pretty sure 
I've seen a LazyLoadingList or something in the jakarta commons projects.

The PROBLEM is submitting this form. I haven't found a way to

auto-allocate space in a collection (or a Map, for that matter) in an
ActionForm for the submit action. Almost every example on 
this I've seen
deals with a fixed number of elements, and most of these 
still focus on the
pre-populate action. These examples completely avoid this issue.

So, when the number of elements on the form VARIES, what is the "best
practice" in design for this? I'm talking about an indexed or mapped
collection that contains other Java Beans. How can you get these to 
submit properly into an ActionForm? If there are options, can you weigh 
the pros/cons of each?

For example, I'm sure a session-scope bean would accomplish 
this, but I stay away from session-scope beans because of clustered 
deployment issues.
   

Make your Form elements String[] objects. These will automatically be populated (and sized) when the form is submitted. Since the ServletRequest interface works with attributes using Strings, this is just about the only way to do things. You can't pass Java objects across HTTP, at least not using GET or POST. You're forced to deal with strings by the protocol.

If you need to use something other than array, another solution is needed. Once your Form is passed to your Action, you can get the number of elements you will need using request.getParameterValues(String). This method returns a String[]; you could get the length of this array and use it to size your collection object as needed.

As an aside, I think you may be worrying about storing things in session more than is warranted. Modern containers are very good at tracking session information across clusters. We have a cluster of over a dozen systems for our site, and we have never encountered any problems with storing data in session. We try to minimize the use of sessions for the sake of efficiency and design, not because of problems with data being replicated across different systems.

Make your Form elements String[] objects. These will automatically be populated (and 
sized) when the form is submitted. Since the ServletRequest interface works with 
attributes using Strings, this is just about the only way to do things. You can't pass 
Java objects across HTTP, at least not using GET or POST. You're forced to deal with 
strings by the protocol.

If you need to use something other than array, another solution is needed. Once your 
Form is passed to your Action, you can get the number of elements you will need using 
request.getParameterValues(String). This method returns a String[]; you could get the 
length of this array and use it to size your collection object as needed.

As an aside, I think you may be worrying about storing things in session more than is 
warranted. Modern containers are very good at tracking session information across 
clusters. We have a cluster of over a dozen systems for our site, and we have never 
encountered any problems with storing data in session. We try to minimize the use of 
sessions for the sake of efficiency and design, not because of problems with data 
being replicated across different systems.

Re: Best place for security checks in Struts?

2003-07-08 Thread Sandeep Takhar

There must be a diagram that shows all the calls
before
it actually hits execute() method.  There are quite a
few.

If you have a base action you can override one of them

processRoles seems to be a logical place...
