Re: how to Internationalized submit button?

[Tadashi Ishikawa]

You can use hidden field and Javascript.


function setAction(target) {
document.forms[0].actionName.value=target;
}

No, it is a "trivialize the complexity" tactic which makes you feel good

property="this/" VS property="something" in nested:iterate

[hemant]

Here is a snippet from my JSP


//Start of Snippet///



 

  
.
...
  
   - 
  

//End of Snippet///

Now the getters work fine. The setters for some reason do not work. Yes, I
have my reset() method and it is as follows

public void reset(ActionMapping mapping, HttpServletRequest request)
{
if (this.collectionOfRanges == null)
{
HttpSession session = request.getSession();
MpiServiceBean msb =
(MpiServiceBean)
session.getAttribute(MpiConstants.MPI_SERVICE_BEAN);

this.collectionOfRanges = msb.getRanges();
}
}

So the collectionOfRanges  is populated before the page is fired up and it
is expected that this method is called before Submit data is fed into
collectionOfRanges .

But for some reason, the setter() methods are not being called.

Is this because of having



instead of



???


If that is true, then it would mean I need a bean for every property that I
want to set. Isnt that cumbersome?

Thanks in Advance

calling a ActionMapping from a structs template page

[Kevin Scott]

here is the template page:
<%@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %>


  
  
  


here the structs-config.xml
   
   


   
 

I would like to be call the SaveRegistrationAction class before displaying the 
="/admin/UserEdit.jsp page.  Can this be done?  Or am I missing somthing?

I can not get any template page to call any action class.  I can only get the 
templates to work with a jsp or html file.

Is there a work around to get this to work if it can not be done?

Wow!!! It is indeed scary.. but God bless you for
solving this interesting problem. Yes indeed that
would enable me to put a login form on every page. I
hope you didn't have brain cramps while trying to
figure this out. I kinda did earlier today while
coming up with a different solution than yours, but
less functional, although I think more secure since
the password and username need not be stored in the
session.

Basically I made my welcome-page a dummy page that
redirects the request to /login.do. I made /login.do a
protected resource and what is ironic is that I made
my home page the "login page" !! (in ).
This kinda turns container-managed authentication on
its head since the protected page becomes the login
action while the login page becomes the homepage. But
surprisingly it seems to work. So when the user goes
to the page, after a redirect they arrive at the home
page. On the home page, they can either fill in the
login form and submit, or click on any one of the
other links in which case the authentication process
is dropped and the user is let go to other unprotected
pages. While this may seem like another big mess, it
satisfies the container since the form-based
authentication is done normally.

All I can say is I wish the servlet specs provided
more methods to make it possible to log the user in
through a method interface. Or maybe all they need to
do is not requiring the login submission to
j_security_check to happen only after the user has
encountered a protected page. Simply, the user should
be allowed to log in even before encountering a
protected page. Maybe they should introduce a new
sub-element in web.xml under login-config that
declares from which pages a login to j_securiy_check
could be submitted and make the login form portable
rather than binded on a single page. That could be a
viable alternative to providing a method interface
cause again which a method interface for logging in a
user, the app developer could poke holes in the
security mechanism. So basically the key phrase is
"make the login form portable".

I'd appreciate hearing your thought on this. Perhaps I
will make make a suggestion to the JCP about it. If
you would like to help that would be great.

Thanks,
Mete

how to Internationalized submit button?

[Hoang, Hai]

I want to internationalize the submit buttons on a form and I don't know how
to do it.  Currently, I mapped the value on the submit button to the
property actionName in the ActionForm class.  Base on the button the use
clicked, I handle it propriately in the Action class, just like event
handling mechanism.  Now if I internationalize these buttons (, the
value will change and my Action class will no longer work.  Is there a way
to work around this problem?

To be specific, following is the detail about my setup

1. jsp page:





2. actionForm class:

public String getActionName() 
{
return actionName;
}

public void setActionName( String actionName) 
{
this.actionName = actionName;
}


3. action class:

ApplicationForm applicationForm = (ApplicationForm)form;
String action = applicationForm.getActionName();
if (action == null)
{
action = Constants.BUTTON_CANCEL;
}

if (action.equals(Constants.BUTTON_CANCEL))
{
applicationForm.setActionName(null);
doAdd(mapping, applicationForm, request, response);
}
else if (action.equals(Constants.BUTTON_ADD)) 
{
doAdd(mapping, applicationForm, request, response);
}
else if (action.equals(Constants.BUTTON_SAVE)) 
{
doSave(mapping, applicationForm, request, response);
}
else if (action.equals(Constants.BUTTON_EDIT) || 
action.equals(Constants.BUTTON_REMOVE)) 
{
doEdit(mapping, applicationForm, request, response);
}
else if (action.equals(Constants.BUTTON_UPDATE)) 
{
doUpdate(mapping, applicationForm, request, response);
}
else if (action.equals(Constants.BUTTON_DELETE)) 
{
doDelete(mapping, applicationForm, request, response);
}

Thank you for your help

RE: Welcome file, servlet mapping in web.xml file

[James Mitchell]

It looks like you are confusing pathmapping with welcome file list

Try this instead:
http://localhost:8080/EGPS/banking/login.jsp

I removed "/action" because that's what you need to call an action, which
will forward to your jsp.

Good luck.

RE: HTTP Status 500 - What does the following mean?

[James Mitchell]

Yes, Struts is not finding your resource file (typically called
ApplicationResources.properties)

It's configured in the struts-config.xml (for Struts 1.1b1) or the web.xml
(for Struts 1.0.x)

It looks like you are using Tomcat 4.1.x, make sure you've configured the
files for your Struts version.  See any of the examples that come with
binary and source distributions for sample configurations.

Validator/Tiles config question

[Eddie Bush]

Do we still need to make the following substitution in  our config files 
if we're running tiles?  I haven't tried it without it yet - was just 
curious.  If we do have to have it, will that bundle work ok with the 
validator?

  
  
  

Thanks so much! :-)

RE: Setter Methods not being called in nested:iterate scenario:+ (

[Martin Cooper]

That your data is presented correctly means that the form bean was set up
correctly when it reached the JSP page. However, when the form is submitted,
Struts will call your reset() method before populating the form bean from
the request parameters. Your reset() method needs to be instantiating the
beans, or your nested properties will not be populated.

Re: Runtime expression not evaluated

[Max Cooper]

You can't mix a string and a <%= %> in an attribute value. It has to be one
or the other. I know, it seems weird, but try it and you'll see.

You should be able to do one of these instead:

<% String idValue = "multiValue" + String.valueOf(index); %>


or

[HELP!] Save token for errors

[Jacob Hookom]

I'm running into a little issue, in my action, if an error occurs I need
to rollback while including the sent parameters, this is causing some
issues, for some reason, it's not appending the params:

// 1 or more errors occurred, rollback to insert page
if (errors.size() > 0)
{
this.saveErrors(arg2, errors);
this.saveToken(arg2);
return new ActionForward(arg0.getInput());
}
// everything went okay, return to success page
else
{
return new ActionForward(
arg0.findForward("success").getPath()
+ "?folderId="
+ info.getFolderId());
}

This same snippet is used in my other actions, but this one is screwy
and always returns nothing for parameters.

HELP PLEASE! :-)

I don't know of an easy way to do that with container-managed
authentication. The reason is that the caontainer wants to decide when to
show the login form. If you always show a form, it won't know where to send
the user when you submit. Tomcat chokes on this (rightly so, considering the
spec) and WebLogic sends the user to the context root or something like
that.

I can think of a really ugly (and insecure) way to have the login form on
every page with container-based security:
1. user submits login form from any page
2. server stores username/password in session and responds with redirect to
protected page
3. browser makes request for protected page
4. server responds with login form that you configured, which is setup to
send a redirect to j_security_check?username=user&password=passwd if it
finds the username/password in the session (or perhaps a pre-populated form
that will automagically submit itself)
5. the server accepts the login and sends you to the protected page, which
may just be a redirect back to the home page

Holy crap is that a scary mess! You might be able to clean it up a bit by
using HTTPS (for security), some sort of frames setup (to lessen the chance
of disorienting the user as things flash by), or the login form could have a
"We're processing your login request..." message with the username and
password in a hidden form within the page that submits itself when the page
finishes loading. That might keep the user from freaking out when the screen
starts flashing and it takes a while for the login (lots of back-and-forth
between browser and server). Okay, I am now of the mind that this just might
work.

Note: You can write a filter to mimic container-based security that does
allow you to specify where to send the user after a submit when the login
form was not shown out of necessity. I like the idea of the app using the
methods defined for container-based security (getRemoteUser(), etc.) because
they are standard and you can switch between container-based an filter-based
with no impact to the rest of the app. We have done just such a switch on a
project that I worked on, and it worked great.

Yes, your app will work like that with this setup. The login scope is the
context, and since both of your sub-apps are in the same context, the login
state is shared between them. Just write your pages to handle both the
authenticated and non-authenticated users. request.getRemoteUser() will
return null if the user is not authenticated.

multiple selected values

I have a html:select that enabled multiple attribute.

 
  
 

I know I can use the 's value attribute to mark a pre-selected item.  But

Ah, but in English, there's a saying about ostriches sticking their heads in
the sand. From Mirriam-Webster Online:

ostrich:
2 [from the belief that the ostrich when pursued hides its head in the sand
and believes itself to be unseen] : one who attempts to avoid danger or
difficulty by refusing to face it.

Not a good connotation for Struts!

Runtime expression not evaluated

Hi,

Can anyone tell me why, in the following code, the id of the image is
"checkBox<%=index%>" rather than "checkBox1", "checkBox2" etc.?  The id of the

Re: Setter Methods not being called in nested:iterate scenario :+(

Adam
Thanks for responding..

The Actionform (rangesform) itself is my root and I have a collection
reference "collectionOfPairs" in "rangesform",  replete with getter/setter
methods.

The collectionOfPairs is instantiated and populated. If not, I would not be
seeing the page with the correct data. right?

As I said earlier, the getters work, the setters do not work. All this
inspite of having the bean in the form.

Thanks
hemant

nested tags / indexed properties / nested beans gotcha. You have to

RE: [ANN] Chapter 18 of the O'Reilly Struts book now available

Simon,

   I have to be finished by the end of the month. O'Reilly has done a good 
thing and forced me to finish the book this month. What this means is that 
several chapters will not make it into this first edition. They will be 
covered in the 2nd edition, which I've already had discussions with them 
about. The simple truth is that I was trying to cover to much material in 
one book and I'm a slow writer.

This is both good and bad. Good because the book is getting so large and 
would have been huge if I actually put every chapter into it. Not to 
mention that it wouldn't be out for 10 more years :) But unfortunately, 
several chapters will not make it into this edition.

Having said all of that, I expect the book to be out in very late August or 
early September. O'Reilly told me that it should be available for 
pre-ordering this month. I think it's taking them a long time to figure out 
which animal they want on the cover :)

RE: Good/Bad Practices

[Joseph Barefoot]

My .02:

I don't there's a right/wrong way to go about this, so long as you are
consistent with your architecture.  Our team has come to the agreement that
less Actions = less files = less headaches, to a certain degree.  We try to
use a single Action class for screens that logically belong together.  For
instance, we have a set of menu options "Select Service Plan", "Edit Service
Plan", and "Add Service Plan".  As you would expect the "edit" and "add"
options both have confirmation screens, and the "add" is a multi-step
process.

So, I used a single Action class (HandleServicePlanAction) for these
functions.  The initial 3 screens each have an action-mapping that use this
action, and we use the "parameter" attribute to specify the method in the
action to be called to initialize/forward to the first screen.  The
"perform" (or execute, in 1.1) method checks for this parameter and invokes
the method by reflection.  After the initial screen, we use an encoding
method on submit buttons, and the value of a button would look something
like "submit(updatePlan)".  Our perform method will 'decode' this from the
request, simply by looking for a parameter that starts with "submit(".  It
then uses the value in parentheses as the name of the method to invoke for
that submit.

It's actually a bit more organized than that, as we use a custom tag to
encode the submit ID and a method in our Action superclass to decode it, so
the only thing in the perform method is the reflective invocation.  We
should argubably create another base class that does even this bit for you,
but we haven't gotten around to it.  You could even optimize the reflective
invocation the way Struts does by caching the Method objects after the first
invocation, but we haven't bothered to do this either, as the performance
hit is nominal.  Searching the request paremeters for the one that starts
with "submit(" is also pretty speedy and thus not really a performance
issue.  If you have so many request parameters that it DOES become a
performance issue, I'd say you have bigger problems anyway--probably a
poorly designed interface.

We have found it easier to deal with config files this way, because there
are fewer action-mappings, and also with our codebase, with fewer files to
deal with.  Of course, you always run the danger of creating a bloated class
this way, but if all of your actions are modeled on this pattern, it's
fairly trivial to move a set of methods to a new class -- you just have to
change the class name in your action-mappings.


peace,
Joe Barefoot

Re: getting nested tags to work with DynaActionForm???

[Adam Hardy]

I am now using nested tags everywhere and not programming my action 
forms with getter and setter methods for anything except one or two 
properties, and the nested beans of course.

Is there any reason to regard this as bad practice?

I also write my value beans with two properties for every real property, 
one is typed, e.g. Date, and the other is the string representation of 
the type. So I also have two getters and two setters.

Also again I have the validation code in the value bean which populates 
the typed property from the string representation property. The action 
form loops through the beans calling the validate methods.

It means I have all my properties in one bean rather than also in the 
form bean - easier to change when the entity changes.

RE: Newbie Struts requirements question

[Mark Nichols]

For what it's worth I'm running (slow, but running) Tomcat 4.x, struts 1.1b1
on an old IBM ThinkPad with a 166MHz CPU and 80 MB RAM. It has Windows ME
installed. Also I've got Eclipse 2.0 with EasyStruts loaded and running here
too.

Of course just as soon as some one is nice enough to gift me a new 2.4 GHz
laptop I'll pitch this one into the nearest lake. =)

Re: getting nested tags to work with DynaActionForm???

[Adam Hardy]

Arron,
I wonder how your lazy initialisation works. I'm afraid I didn't look at 
the code - since you said you wanted to explain it to the masses anyway, 
perhaps you won't mind explaining, rather than telling me not to be so 
lazy myself. Basically, if you have your example:

In the request parameters:

monkey[1].bunch[2].banana[3].color

how does your collection wrapper know what class to instantiate for 
monkey, bunch, etc etc? Is this something that you configure in xml 
somewhere? Presumably an extension to dynaform configuration?

You don't have to have a web server to run struts - you do need a servlet
container such as Tomcat. I don't know anything about Windows ME, but I used
to run Tomcat of Windows 98 at home, before I upgraded to Win2000.

Re: Related Select lists

[Adam Hardy]

I would output the data into javascript arrays in a JSP. The tags work 
just as well mixed in with javascript as they do with html.

Depends what your target browser is. If it includes NS4 you've got more 
problems, but otherwise it should be fairly simple - use the onchange 
event on the select boxes to rewrite the options in the next select 
using the DOM manipulation methods.

I don't do much hardcore programming on my home computer, but I do have
Windows XP on it.  For non-programming reasons, I couldn't live without XP.
I love it.  On my work computer I have Windows 2000 Pro, and all of my
programming software runs fine on it.  However, I am using WSAD, so I don't
know if the Apache web server would be much different.  I do love my XP

Re: Problem with session ojects: memory size, updates

[Adam Hardy]

Value objects that can be serialized can be automatically saved to disk 
by your application server, if it provides memory management 
configuration options.

If your session fills up with data, then the app server can be 
configured to remove the data from memory and store it on disk. I think! 
  Never actually done it myself.

RE: Form not keeping changed values

[Brian Holzer]

Hi Pam,
   I believe that if you set the scope of your form to session, rather than request 
and set redirect="true" for the definition of your local forward in the 
struts-config.xml file. I think that your changes should remain in tact when you get 
to the next Action ( this assumes, of course that your reset() method on the form does 
nothing).  I don't know if this will fit into your design but I believe that this will 
work.

That's where the issue lies...it forwards to an action. It seems that an

the design and see if I can come up with a better solution.

[OT] Keystrokes

[Mark Nichols]

I know it's not Friday (here) (yet) but I wanted to share this mindless bit
of fluff. Go to http://dolphin.bitdevil.com and download the client there
and install it on your PC. It counts the keystrokes you make and ranks you
against the other dolphin users. Some parts of web application development
are surprisingly keystroke intensive while others not so much.

Just for grins I have created a team where like minded Struts users can
combine their keystrokes. Once you have an account established, join
'teamStruts' (password: jakarta). The leading team has 486 members and over
315 million keystrokes to their name. Are Struts users up to the challenge?
Join up and find out...

Does anybody know how to use Javascript Version 1.2 with the struts tag

[Declan O'Shanahan (CAPE)]

Hi there,

I am using Javascript with Struts for validation of input fields and I need
to be able to use Javascript version 1.2. I have checked the struts-html.tld
and there is no attribute to set the Javascript version. In the html that
gets generated the Javascript version is set to 1.1.

I have checked the class
org.apache.struts.taglib.html.JavascriptValidatorTag and the method
getJavascriptBegin sets the Javascript version to 1.1. If anybody knows of a
way to change the Javascript version to 1.2 without changing the struts code
base I would like to know how to do it.

Regards,

Declan.

Lost bean ?

[Bugra Cakir]

Hi,

I have forwarded to jsp from an action servlet a bean
called "modform" then in this jsp file I populated
a form with information in this bean. Then post to
another action servlet. But within this servlet it is
lost i think. What is the matter ?

Let me see if I understand it properly.

If a Japanese user sets browser so that his preferred
language is Japanese (accept-language: ja), and sends it to a German
speaking Struts application, the application will respond with
, even though it should have said "de" for
German.  Is this what will happen?

This is what I suspected and I fear Struts may be broken in this area.
There needs a way for application to insert its own logic to
interpret the acceptable languages from the request, determine the best 
language available, and set its decision on the request object.  Then,
locale="true" generating  makes sense.  Otherwise,
it is a mechanism that create a false information, and is rather
harmful than useful.

Is there anyway for Struts application to call setLocale on the request
object before it constructs Content-Language header?

Exactly what it is in container-managed authentication, e.g. a Principal.
Container implementations could hold whatever the container decides they
should hold.  *That* data would *not* be portable across containers--only
the Principalness would be, and the addUser(Principal) method (or some
such).

Groups are roles, just as they are in container-managed authentication.

No, not necessarily, because container-managed authentication via the
mechanisms supported out of the box does not need them.

Check out Cocoon at http://xml.apache.org/cocoon/index.html. It's 
dynamic xml/xslt publishing system written in java and has a nice 
caching approach so it doesn't do the transform every time. it's not 
based around struts or jsp but it seems very nice if you're in an xml

RE: (newbie) html:text tag, enforcing numeric input

[Kamholz, Keith (corp-staff) USX]

You should generally use Strings for your form bean properties.  When you
validate it, check to see if the numbers were entered.  Then in either the
form or the action, you can convert the String to some kind of number, using
the Integer class.  The class has some kick ass methods for type
conversions.
Good luck.

What'a a "user" (i.e. what properties does one have)?  What's a "role"?
How about "groups"?  Oh, and now I need SSL certificates.  And
public/private keys.  And application-specific extension properties.  Oh,
don't forget to link into external authentication infrastructures (like
Project Liberty, or Passport in the MS world).  But I've already *got*
users defined in my database, and just want to use those.  And ...

Is that global warming I'm feeling?  :-)

A nice middle ground that would not require boiling the ocean would be a
simple interface that allows callers to add, update and remove users and
roles.  I find that the only thing I usually need above and beyond the
current container-managed security API is the ability to create new users
and roles.  Every container I've worked with has the ability to make these
calls with their own APIs--all the concepts and logical objects are the
same--but the implementations basically suffer from name incompatibilities.

We only use stored procedures on our database, so autoCommit(true) is appropriate for 
us since all transactions are committed/rolled back within the stored procs 
themselves.  That was sort of an internal assumption within our company that wasn't 
mentioned in the doc.

 That way you have explicit control over the transaction.  If, however,

Ok from what I gather from the responses, it is not

of the CachedRowSet.  However I would still like how
to do this. I've looked at webPIM, and were not able
to download as there are no jar files or zip files
package I saw at sourceforge.net, am not about to
pick bits and pieces and spend so much time putting it
together, if a better download site is provided i'd

Am still not clear if it requires a Collection type

Container managed security is just like any other technology -- it is
designed to meet a specific set of requirements.  If your requirements
match up with those features, great ... it's easy to use it.  If they
don't, then you can't.

My caution to you, though, is that rolling your own security makes it way
too easy to write insecure applications, because almost nobody who writes
apps is a security expert.  Plus, it's a pretty large amount of work to
get this right.  And those developer manhours are expensive.  And those
hours could have been used to work on your application instead of your
infrastructure ...

Also, if your app needs (or ever will need) EJBs, you're going to have to
use container managed security anyway.

I do not believe there will ever be such a thing as a "generic"
application security solution that meets a large majority of people's
needs.  The problem is that the needs (well, at least their wants :-) vary
too much, so any given "application security solution" is going to have
its own design limits that people are going to run into.

I prefer the more granular approach, with many actions and JSPs over a more
complex and generalized approach. In my case I find that having
single-function actions and JSPs leads to easier coding today (and therefore
easier maintenance tomorrow). I can also split the work up over more
developers, rather than "single threading" development through one complex
action.

Our intranet application has about 60 separate 'screens', each with its own
action. Maybe overkill, but for a first attempt at Struts this pattern has
made life easier by far.

I see...
I don't know why you're using  though.  You
should have the 'do' extension in your JSP.  You shouldn't have to forward
like that, or expect it to be outputted when run.  So if I'm understanding
your situation correctly, you should just have  in your JSP, then you won't have to worry about forwarding or any of
that other stuff you're doing.  Does that make sense?

deal, but I really wanted to try and figure out what was going on.

What I really need to do is to see if this behavior exists in other
WebSphere
environments.  Maybe 3.5.6 or 4.0.x. time permitting, I haven't seen anyone
else complain in this forum, so it's probably not a reoccurring problem.

It's not going to make it for Servlet 2.4 (which is currently in public
review, so you can see the proposed changes for yourself).  Dealing with
*all* of the issues required to make some sort of authentication plugin to
containers is probably a year's worth of of Expert Group work to define an
appropriate specification.

Nothing stops you from accomplishing exactly this functionality.  The
page you describe would *not* be protected by a security constraint -- but
the logic that produces that page can tell if a user is logged in or not
(call request.getUserPrincipal() or request.getRemoteUser()) and vary the
generated HTML based on whether this value is null or not.

The APIs for Converters is not currently Locale-sensitive, although it
could probably be made possible through an extended interface
(LocaleConverter or something) that passed an extra Locale argument along.

Re: CachedRowset with logic:iterate tag

[Chad Johnson]

You could use the "forEach" tag from JSTL
(http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html).  "forEach"
can iterate over ResultSet's (and RowSet's via inheritance) with the
assistance from the helper class: javax.servlet.jsp.jstl.sql.ResultSupport .
ResultSupport can convert ResultSet's to the JSTL friendly Result class.

There is no current mechanism to do this kind of thing.  One approach
would be to use the general purpose "parameter" property to pass a
reference to some external resource file that contains all the stuff that
your particular action needs to configure itself.

Besides the Struts Test Case reference from another poster, you'll be
interested to know that both Cactus and JUnit tests are included in the
Struts sources, and can be run from the build.xml scripts.  To see them,
grab a nightly distribution of the sources
 and start at
the "test.junit" and "test.tomcat.all" targets in the top-level build.xml
file.

Similar techniques can be used to incorporate tests of your own apps that
are based on Struts.

This article seems more concerned with the issues regarding a logical
transaction that takes more than one HTTP request to complete -- you don't
want to keep an actual database transaction open across requests.  But a
side effect of this approach will definitely help reduce memory occupancy
if you don't cache the data in memory.

You should also note that an app server could have built in facilities to
"swap" active but idle sessions out to a database or other persistent
storage mechanism, the same way that an operating system can swap out idle
processes.  It's worth checking the docs for your server to see what is
available in this regard.

Advantages of Container-Managed Authentication ??

[Mete Kural]

Hello,

So far I thought that container-managed authentication
was the way to go. Why I thought so? I thought:

1) Since such authentication is implemented by experts
in the field there's a much greater chance that their
implementation would be much more secure to attacks
then my own application-managed implementation.

2) The container has much more control in a servlet
environment than a web-app. Therefore if the container
is aware of the user who is making requests rather
than just the web-app, this would be an added security
incentive.

3) Struts tag library provides some neat tags such as
conditional tags based on the logged-in user's
identity and roles, and probably such tags will
flourish even more in the future. These tags support
only container-based authentication (am I right
here?). So if you're using container-managed
authentication you can use these tags, otherwise
you'll have to implement your own.

Do you guys think that three so-called advantages that
I've listed are really valid advantages and is there
any more advantages associated to container-managed
authentication?

Basically I'm asking all these questions because I'm
trying to decide whether I should abandon
container-managed authentication and implement my own.

Thanks,
Mete

Despite their protestations to the contrary, having two getters like this
is also a violation of the rules (the JavaBeans rules, that is).  It would
also be improper to have a getter that returns one type, and a setter that
accepts a different one.

"So where are these rules?" you might ask.  "How can I avoid such faux pas
in the future?"

http://java.sun.com/products/javabeans/

has a link that gets you to the JavaBeans specification, which includes a
whole chapter on how well mannered JavaBeans properties expose themselves
to the world.

I have read MANY previous discussions on this list debating container vs.
app managed security. Usually they end up suggesting that since container
managed is limited, if you can't use it, then roll your own, similar to the
above comment. Craig's reply also said basically the same thing.

So is anybody aware of an Apache-like project that is attempting to
implement a "generic" application security solution for this problem? I
mean, with filters and the ability wrap the request, as Max mentioned, a
pretty robust solution could be developed that could be easily extended for
different db schemas, etc. Yet I feel like we're all reinventing the wheel
here, each of us implementing tactical rather than strategic solutions.

Sorry if there's already been a discussion of these projects, but I looked
and couldn't find any...

Thanks,
Joe

RE: Good/Bad Practices

[Mark Nichols]

I prefer the more granular approach, with many actions and JSPs over a more
complex and generalized approach. In my case I find that having
single-function actions and JSPs leads to easier coding today (and therefore
easier maintenance tomorrow). I can also split the work up over more
developers, rather than "single threading" development through one complex
action.

Our intranet application has about 60 separate 'screens', each with its own
action. Maybe overkill, but for a first attempt at Struts this pattern has
made life easier by far.

This alternative seems attractive to me, but I'm not
sure I have truly grasped how it works. I'm going to
try to paraphrase, so please correct me if I'm wrong:
- I would provide a link on the public homepage that
says "Login here" on it. When users click the link
they would go to a dummy protected page that simply
redirects the user back to the homepage. Once they
login through that they're automatically back in the
homepage and they're logged in!

One thing that I want to implement is providing the
login form within the home-page to make it a
single-step job for them, so they'll see the login
form on the side of the page when they first come in.
Otherwise there are two steps involved, first click on
the login link to go to the login form and then submit
the login form. How do you think I can do that?

Think about Amazon. You can either be logged-in and
not logged-in and it will still work. If you're
logged-in the website treats you like a familiar
customer, if not just default. That's the exact same
functionality that I'm trying to implement here. I
hope this gives a wider picture of what I want to do
and perhaps you know a better way to do this than how
I was currently planning on doing it above.

Re: Difference between DynaValidatorActionForm and DynaValidatorForm

[David Winterfeldt]

The key used to look up a set of validation rules is
different.

DynaValidatorForm 
--
The key passed into the validator is the action
element's 'name' attribute from the struts-config.xml
which should match the form element's name attribute
in the validation.xml.


DynaValidatorActionForm 

The key passed into the validator is the action
element's 'path' attribute from the struts-config.xml
which should match the form element's name attribute
in the validation.xml.

That's exactly what I want to happen. To preserve the
loggedinness of the user even when they go out of the
protected area into the public area.

Hmm.. I hope the JCP will include such a mechanism in
Servlet 2.4. It would be nice to enable pre-processing
on the form-based login submission in a servlet and
then submit that to the container. Perhaps this is not
a valid use case, but it seems to me that it may be
attractive in certain scenarios.

Think about Amazon.com. On Amazon, you can surf
through the shopping pages with or without being
logged in to your Amazon account. If you're logged in,
some special features are enabled such as personal
book recommendations on the sides of the pages. If
you're not logged in it just treats you like a default
customer that it doesn't know about. In this case, it
is necessary to provide a login mechanism to better
serve the customer even if login is not required.

Re: TilesRequestProcessor (WAS: Re: How do I navigate from one subApp to another in Struts1.1?)

Subject: Re: TilesRequestProcessor (WAS: Re: How do I navigate from one subApp to 
another in Struts1.1?)
From: "Kevin Henrikson" <[EMAIL PROTECTED]>
 ===
Thanks for the reply Cedric.

So basically what we've tried is to subclass TilesRequestProcessor
so we ignore tiles definitions and apply our path resolution logic to URI's
then call super.doInclude() or super.doForward().  Where we get stuck is
when we use a tiles definition in the struts-config.xml in an 
for instance we aren't able to apply our path resolution logic to the URI
after
tiles resolves the definition but before it is the request is dispatched.
Would it
be possible to apply a hook(overridable method) by refactoring the last part
of
TilesRequestProcessr.doForward()?  Something like:

protected void doDispatch(ServletContext ctx,
  HttpServletRequest request,
  HttpServletResponse response,
  String uri
  boolean doInclude)
{
  // Do dispatching : search dispatcher, then dispatch
  RequestDispatcher rd = ctx.getRequestDispatcher(uri);
  if (rd == null)
  { // error
  response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,
   getInternal().getMessage
   ("requestDispatcher", uri));
  return;
  } // end if

// Unwrap the multipart request, if there is one.
if (request instanceof MultipartRequestWrapper) {
request = ((MultipartRequestWrapper) request).getRequest();
}

  // If request comes from a previous Tile, do an include.
  // This allows to insert an action in a Tile.
  if( doInclude )
rd.include(request, response);
  else
rd.forward(request, response);   // original behavior
}

This way subclasses could have a chance to modify the URI
or do some custom request/response handling.
As for the InsertTag it looks like in InsertHandler.doEndTag the call to
pageContext.include(page) is the only other place request dispatching
happens.
If a method was added here to again allow subclasses to override this call
and possible
do custom URI resolutions maybe a doInclude(String page) that calls
pageContext.include(page).  Then I guess we'd also need to subclass the
GetTag since
it extends the InsertTag.
Does this seem plausible?  Are there other places in tiles that do
request dispatching?
 Any problems with this approach?

Oh, let me clarify,

In the VisualAge WTE,   is correctly rendered

I ended writing a servlet for WebSphere 3.5.5 that takes the
/app/login call and forwards it to the correct /app/do/login path.  Not a
big
deal, but I really wanted to try and figure out what was going on.

What I really need to do is to see if this behavior exists in other

RE: Form not keeping changed values

That's where the issue lies...it forwards to an action.  It seems that an
action calling an action isn't a workable solution.  I'll have to revisit
the design and see if I can come up with a better solution.

Actually Dreamweaver does have a template control system that can keep 
people from editing outside their part of the page. So designers can 
design a complicated template and declare that only the middle cell and 
the text in header can be edited. The template info is done in such a 
way that the designer can update a template and it will propagate 
through all the pages that use that template. Not exactly dynamic but 
easier than search and replace! I don't remember if it has tools to keep 
users in out of different parts of the site though.

Re: Dynamic Forms & FormBeans

[JensStutte]

Hi,

i had quite the same problem, one method is to use normal, non-struts input
boxes within a struts form for the dynamic part of the form. The generated
parameters can then be evaluated in the FormBeans validate function, since
you get the HttpRequest object there. I do not know a pure struts way to
achieve this (but after i made this workaround, i did not search any more ;
-).

Regards,

Jens Stutte

Hello Struts-World.

Here's a Struts Newbie query I've got.

I really like being able to associate a FormBean with a Struts form and
then
doing the validation etc. at the server end. I understand about having to
have attributes in the FormBean that match the names of the input elements
in the HTML form.

However, I cannot think of a way of creating a FormBean that can cope with
a
form that has entirely dynamically generated output. For example, one that
creates a list of items in a shopping cart where every item has an
associated "delete" checkbox. I can ensure that each checkbox has a similar
name, (I'm using the name to indicate the cart item to which it relates
rather than the value at the moment) but how can I map these to attributes
in the Form bean? At design-time I will not know how many attributes I need
to supply, or what their full names will be. If I use the same name for
each
checkbox (i.e. all map to the same FormBean attribute) and hold the cart
item ID in the value how will I be able to store the different values?

I'm sure that there's a good "Struts way" to do this but I cannot see one
at
the moment. Can anyone out there enlighten me?

Many thanks.

Neil.

P.S. I'm currently using Struts 1.0.1 and would prefer to stay that way
until I get the current iteration of the project out of the way.

Check out Cocoon at http://xml.apache.org/cocoon/index.html. It's 
dynamic xml/xslt publishing system written in java and has a nice 
caching approach so it doesn't do the transform every time. it's not 
based around struts or jsp but it seems very nice if you're in an xml 
heavy setting.It also has that friendly Apache license.

Form bean properties data types and conversions

[JensStutte]

I have seen, that in Struts 1.0 there is some support for automatic
conversion of request parameters to form bean properties, which seems to be
extending in the 1.1beta (i did not use it, but i navigated through the
sources). There seem to be converters for date and time data types in the
beta. So far, so fine.

But i could not get any hint on the localisation. As Struts knows in his
request the locale of the user and offers it to the Action programmer, will
this locale be used to make any automatic conversions, too? For Struts 1.0
this seems not to be the case, as far as i could see in the sources in half
an hour. And the calls to the new DynaBean classes from the jakarta.commons
project seem to lack any locale support, too. I can not see much use in an
automatic conversion function of Dates (but also numbers), whithout any
respect to the users locale, so i wondered if i am missing something.

Could someone shed som light on this?

Regards,

Jens Stutte

The key is in the crazy single and double quotes--your second example is

dynamic links

[Graham Lounder]

Hello All,

I'm trying to make a link that sends a parameter containing the URL of the
page which called it.  I have all the URLEncoding figured out, my problem is
getting it into the  tag.

I have tried

bla

and

bla

neither of which work.


Right now what I'm doing is:

<% String myLink = "/bla/bla.jsp?returnURL=" + returnURL; %>
bla

but this is very ugly.  I don't want to have to make a String variable for
each link on my page.  Any ideas?  Am I missing something?

Override processPreprocess or ActionServlet? (Best Practices)

[Jerry Jalenak]

Following a web application security presentation yesterday, it became
apparent to me that I needed to further my security model to ensure that a
user has a valid session at the beginning of every action.  What is the
recommended 'best practice' to do this?  Should I write a BaseAction that
extends Action?  extend the ActionServlet?  do something in
processPreprocess?  How is everyone else doing this?
