RE: Arrgh!!! my property has been cursed and my bean doesnt like the field on my farm , uhh form I mean
Ah well now, its funny you should be mentioning that.
As it happens Old Mc Andrew did once have a method to set the field with a
boolean, but changed it to take a string instead as he is quite set in his
ways and has never liked booleans (as he learnt from a young age that
providing a certain true or false answer instead of 'maybe' tends to create
a few too many expectations in folk not wise to the ways of software
development...).
He has looked at his ActionForm code to try and determine is there is a
second setter somewhere (he even looked behind the grassyKnoll() method) but
found nothing. Old McAndrew has been known to occasionally miss things that
are right under his nose however, and will continue to look.
There ARE however multiple getter methods, or to be precise there is a
method getHeaderTransform() and an isHeaderTransform() the latter of the
two returning a boolean. (The other similar fields also have these but they
still work.)

Or to be a little bit more specific...
Old Mc Andrew had a form
and on that form he had a field
with the name headerTransformation
but naughty Mr Struts simply would NOT call the method
setHeaderTransformation in his ActionForm
even though it had not been a problem yesterday!
I hope old McAndrew isn't trying to have his cake and eat it too, by
having more than one mistress, err, setHeaderTransformation() method that
takes a different type of argument :-). Such things violate the JavaBeans
specification's design patterns, and will cause the JVM to think your
property doesn't have any setter method at all.
No matter what Andrew looked at everything still seemed fine but it just
didnt work!
He tried changing the field from a checkbox to a boring old text field
He tried dumping the request parameters to see if anything was dodgy there
- maybe multiple values were being submitted for that property?
but no - it all checked out ok, no matter where he looked.
Poor Andrew was getting VERY alarmed.
Then he had a clever idea!
He changed the name of the field on his html form to
headerTransformationx
,
he also added a second setter named setHeaderTransformationx to his
actionform and then tried again.
Amazing! This time it worked!
Mr Struts went right ahead and called the setHeaderTransformationx method.
Andrew couldnt believe his eyes.
Makes it even more likely that old McAndrew is trying to double dip :-).
After all, a property named headerTransformationx is completely naive
and innocent about the existence of any property named
headerTransformation.
Just to test he renamed the field back to headerTransformation
and sure enough nasty Mr Struts gave it the cold shoulder again.
Now Andrew is very confused. He hasnt the slightest clue why a parameter
named
headerTransformation is completely ignored by Mr Struts, while a
parameter
named headerTransformationx is welcomed with open arms!
Well boys and girls, perhaps you can help poor Andrew with his problem?
Can anyone give him a reason why silly Mr Struts has a bad attitude
towards
his fieldnames?
Mr. Struts is like Miss Manners -- he frowns on trying to have serious
relationships with two property setters at the same time :-).
details
Ive looked at the request parameters (dumping them from processPopulate()
in
the request processor just before the form is populated.
headerTransformation=xxx is in there alright, and its not multiple values.
So it fine there,
but the setter in the actionForm is not getting called.
The code in my actionform is:
public void setHeaderTransformationx(String value)
{
System.out.println(Setting headerTransformationx to + value);
_headerTransformation = value;
}
public void setHeaderTransformation(String value)
{
System.out.println(Setting headerTransformation to + value);
_headerTransformation = value;
}
public String getHeaderTransformation()
{
return _headerTransformation;
}
I also set _headerTransformation to null in the reset() method (it used to
be a checkbox before I started trying to diagnose the problem).
And my html form has a field with the code:
input type=text name=headerTransformationx
onchange=submitWithMethod('update');/
(or
input type=text name=headerTransformation
onchange=submitWithMethod('update');/
depending on which of the two setters Im testing)

Model 2 and Caching
Hey, For a prelude: I was chatting with my dad over a beer about how the company he works for is training all of their HR people on how to use Dreamweaver to generate content for their internet/intranets. Appalled, I asked him whose bright idea was it; to which he responded some independent consultant who was touring the various facilities doing training (and he's never heard of Jakob Neilsen!). To give a 100 person staff a copy of Dreamweaver and tell them to go nuts... is insane! Now for the meat: I am going to be putting together some knowledge-base material for my dad on the advantages of XML and the Java platform. Particularly XSLT, FOP, Xalan transformation servlets, etc. They will be generating training/informational material that could be viewed on the web or printed. Since I'm a big speed freak when it comes to dynamic content, I am under the belief that Model 2 would only slow the requests down even more, beyond the straight pulling of data from the DB and iterating it out with Struts. It seems to be rationalized tradeoff between portability and speed. Would writing the xml data out statically and storing it, then using translets for XSLT offer any speed improvements over simply caching with OSCache or other similar tags? Basically, any rants about Java and XML will help, I've read quite a bit, but any personal experiences would be appreciated!

RE: Model 2 and Caching
lol Reminds me of something I heard a year or two back (from a friend of a friend...) about how one of the state governments in Australia paid a consultant $30k or some such ridiculous figure to study how government departments could improve their service. The resulting reports main recomendation was that each phone in government offices have a pen and paper placed next to it - that way when a call came in they would be able to take a message if the person being phoned was not in so that they could get the number and call back. Im not sure if they had to commision a second study to figure out where to cut the budget in order to have enough money to buy the pens... ;-) -Original Message- From: Jacob Hookom [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 18, 2002 14:30 To: 'Struts Users Mailing List' Subject: Model 2 and Caching Hey, For a prelude: I was chatting with my dad over a beer about how the company he works for is training all of their HR people on how to use Dreamweaver to generate content for their internet/intranets.

Hello,
The JSP size limit is per page, not per request. You should be able
to split a little bit more the faulty page/tiles, using tiles insert

Also, considering using less tags is a good option (like options ...

Subject: RE: Indexed Properties - soluce :-)
Hi there,
Actually when you are looking at the stuff done in the JSTL
all three ways pretty much work, because it contains a
scripting language ;).
Are there any plans on integrating it within Struts? I like
both libraries very much, and I recall a discussion was going
on a while ago about it?
If it is done this would make it is either:
1. property = all I want to write
2. property = %= java expression %
3. property = ${myRadios[param.index]}
My current thinking is that we'll make some variant of #3 available in
Struts tags, in a release after 1.1. But this will primarily be as a
transition tool -- subsequent releases of Struts will be designed such
that you should use JSTL tags directly, as opposed to the
corresponding
Struts tags in the bean and logic libraries. For the html tags,
we'll end up with JavaServer Faces tags when it's released.
(here with 'index' as a request variable ;))
Manfred.

Subject: RE: Indexed Properties - soluce :-)
All suggestions are welcome Eddie.
Your idea and your argumentations are good, but your proposed
solution doesn't work :-(
Explanations :
In a taglib property you can use either a string value or a
RunTime Expression (if allowed in the TLD).
If you use a string you have something like : property=all
I want to write
If you use a RT Expr you have something like :
property=%=java expression%
The tag libraries interpreter verify if the content of the
property begins with %= and ends with % . In this case it
suppose that it is a RT Expr and values it. In all other case
it supposes that the content is a string.
With your suggestion, property=myRadios[%= index %] the
tag libraries interpretor see that there's not %= at the
begining and % at the end. Then it passes the value
myRadios[%= index %] as a string to the taglib.
When the taglib get the content of property, it will analize
it and see that it is a indexed property because of [..] but
won't be able to interpret it and will launch an exception like :
java.lang.IllegalArgumentException: Invalid indexed property
'myRadios[%=index%]'
However, it is important to say that your advice is totally
good if you want to use a dynamic value in standard html tag.
I you have another idea to clean my code, don't hesitate to
propose it.

Re: TilesRequestProcessor (WAS: Re: How do I navigate from one subAppto another in Struts1.1?)
The hooks you use (doForward and doInclude methods) have been introduce to let Tiles catch the calls to RequestDispatcher() ;-). It is true that actually Tiles don't provide similar hooks. I am currently working on a new version of the RequestProcessor to solves some problems with multi modules. So, things will change. I am not sure to be able to provide one single point for catching calls to include, but I will try to minimize the number of places where it happens. Actually, Tiles do include in the RequestProcessor, and in the InsertTag (in Struts1.1).

Unfortunately if we try this same code with the TilesRequestProcessor (so we can get the cool ability to do includes/forwards with tiles definitions directly in the struts-config.xml) it won't work. Is there a 'hook' per say inside a tiles that is easily subclassed to provide us access to do filepath resolution before the URI is passed to the RequestDispatcher or pageContext.include() is called? If not I think this would be a very nice enhancement. Basically struts allows us to hook in to it's RequestDispatcher calls but when tiles in present there is nolonger a single point of RequestDispatching. To workaround this now we'd have to tweak some internals of the InsertTag/GetTag since it also call include directly.

extending Action issue
Our company has been using struts for about a year now. We have subclassed Action and created our own BaseAction to support some additional functionality and to create an abstraction between changes to Action in the future and our existing code. We have done the same with most core Struts classes. With 1.1, a new subclass of Action, DispatchAction has been created. Since DispatchAction subclasses Action, BaseAction and DispatchAction are at the same level. In order to use DispatchAction and keep the functionality of BaseAction I have thought of two ways to do it, but neither is optimal. 1) Subclass DispatchAction and put the functions from BaseAction into a BaseDispatchAction. The problem is maintaining the same code in two seperate classes. 2) Turn BaseAction into a composite class and add an Action as a property of the class. This would allow the most flexibility since any Action object could then be used. The problem is that this would require some sort of change to either the struts-config.xml and/or to the ActionServlet. This is because somewhere after the new BaseAction gets instantiated, an Action would need to get passed in. Does anyone have any thoughts on how to solve this problem?

RE: extending Action issue
I tried using your first suggested approach and got tired of it rather quickly. I found a third approach was the best bet. This is to copy and paste the source for struts DispatchAction into a new class in your application (you could call it BaseDispatchAction or something like this.) The only difference between this and the original is that this extends your BaseAction instead of directly extending Action. Your dispatch actions then extend this class instead of DispatchAction. It may be a bit crude, but its very quick to implement and works well. Of course if you upgrade your version of struts and there are changes to dispatch actions you wont pick them up, and if you import DispatchAction classes from other apps you will need to modify them to extend your class and recompile, but if those arent big issues to you, then this is probably the simplest approach. -Original Message- From: Melzer, Steven [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 18, 2002 19:34 To: 'Struts Users Mailing List' Subject: extending Action issue Our company has been using struts for about a year now.

Struts ActionServlet extension processActionForward method problem
Hi, In order to add some extra functionality that we needed generically, we extended the org.apache.struts.action.ActionServlet class and coded an overridden version of the processActionForward method. In our current project we needed another extra thing, to use only in this project so we extended the already extended ActionServlet class once again and implemented another overridden version of the processActionForward method. This extended version of the ActionSevlet class is defined in the web.xml descriptor as the action servlet. The problem occurs everytime Struts calls the processActionForward method, it calls the first overridden method and not the one from the ActionServlet class that was defined in the web.xml descriptor.

AW: Reusing forms and redirecting to specific actions
Hello! I've been lurking a long while and I think I decided to take up the Struts thing entirely. I've got an application that will needs to use several forms which are pretty much related, or in other words they look quite the same. But the action attached to it is different. Can I create one super-form that'll handle the input and based upon the page invoked call a specific action for it? This shouldn't be a problem! You'll just have to configure it in the struts-config.xml! Kind regards, Arne -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

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?

Good/Bad Practices
Hey everyone, I've been trying to get in the habit of using good struts programming practices, (without making things too hard on myself). I have another question for anyone that could give me some input on it. I'm working on a data entry application, and the user can make three different types of entries. Let's call them A, B, and C. They each have some form fields in common with each other, but each has a couple unique fields. To add an entry, I have a separate JSP for each, and different action mappings for each (that all refer back to the same action class). This works fine. Now I'm working on an edit function for the entries. I have a link within a logic:iterate tag that displays a link to an edit form. I tried using one action and one JSP for the edits, but it gets very messy trying to allow for the different types of entries. Is it a bad idea to use lots of different action mappings and different JSP's for each operation for each type of entry, even though they are similar and all have to perform very similar operations? Or should I go to great lengths to make very complex generalized actions and JSP's that can handle any type of entry? I'm not sure how understandable my question is, or if it's a stupid question, but I want to get this figured out before I spend too much more time on the 'edit' functionality. I'm having some issues, and I keep redesigning the operation, so I'ld appreciate some input before I rewrite this shiznat too many more times.

Form bean properties data types and conversions
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 -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Dynamic Forms FormBeans
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.

To give a 100 person staff a copy of Dreamweaver and tell them to go nuts... is insane! 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!

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 action ..
forward...
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?

The hooks you use (doForward and doInclude methods) have been
introduce to let Tiles catch the calls to RequestDispatcher() ;-).
It is true that actually Tiles don't provide similar hooks. I am
currently working on a new version of the RequestProcessor to solves
some problems with multi modules. So, things will change. I am not sure
to be able to provide one single point for catching calls to include,
but I will try to minimize the number of places where it happens.
Actually, Tiles do include in the RequestProcessor, and in the InsertTag
(in Struts1.1).

Cedric,
We subclass the Struts RequestProcessor to provide some special
resource
resolving, (i.e. override the doForward and doInclude methods to do some
special file path resolution). Unfortunately if we try this same code
with
the TilesRequestProcessor (so we can get the cool ability to do
includes/forwards with tiles definitions directly in the
struts-config.xml)
it won't work. Is there a 'hook' per say inside a tiles that is easily
subclassed to provide us access to do filepath resolution before the URI
is
passed to the RequestDispatcher or pageContext.include() is called?
If not I think this would be a very nice enhancement. Basically
struts
allows us to hook in to it's RequestDispatcher calls but when tiles in
present there is nolonger a single point of RequestDispatching. To
workaround this now we'd have to tweak some internals of the
InsertTag/GetTag since it also call include directly. Is there any plans
to
centralize calls to RequestDispatcher, and pageContext.include() in the
tile
code base now that tiles in more fully integrated with the Struts code
base?

Normally it doesn't matter.
The Tiles servlet was used from 1.1dev until 1.1b1 to initialize
Tiles. It contains some request processing methods used only by
Struts1.0.
The TilesRequestProcessor should normally not impact on the normal
request processor work. It just check if a forward or include is done on

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. Quite frankly, I'm not convinced your use case is very compelling, but I undoubtedly don't understand the whole picture, either. Think about Amazon.com.

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. Craig Thanks, Mete __ Do You Yahoo!? Yahoo!

Re: Struts/Container-Managed Authentication Question
Hello Max, --- Max Cooper [EMAIL PROTECTED] wrote: One thing that you cannot do with container-managed security is direct the users to the login form page to force them to login. As an alternative, you can protect a page and send users there, so the container will send them through the login form. For instance, if your login form is /loginForm.do, you could make a page (even a redirect back to your home page if you want users to end up there) named /protected.do and then setup a security constraint for that page. Your Login link would be a href=(contextPath)/protected.doLogin/a with this setup. 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. I think you can acheive your desired functionality with those techniques. If you need more info, I'll be happy to help out. Another alternative is to use a filter to mimic container-managed security [including wrapping the request with your implementations of getRemoteUser() and isUserInRole()].

RE: Good/Bad Practices
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. /mark -Original Message- From: Kamholz, Keith (corp-staff) USX [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 18, 2002 9:32 AM To: Struts (E-mail) Subject: Good/Bad Practices Hey everyone, I've been trying to get in the habit of using good struts programming practices, (without making things too hard on myself). I have another question for anyone that could give me some input on it. I'm working on a data entry application, and the user can make three different types of entries. Let's call them A, B, and C. They each have some form fields in common with each other, but each has a couple unique fields. To add an entry, I have a separate JSP for each, and different action mappings for each (that all refer back to the same action class). This works fine. Now I'm working on an edit function for the entries. I have a link within a logic:iterate tag that displays a link to an edit form. I tried using one action and one JSP for the edits, but it gets very messy trying to allow for the different types of entries. Is it a bad idea to use lots of different action mappings and different JSP's for each operation for each type of entry, even though they are similar and all have to perform very similar operations? Or should I go to great lengths to make very complex generalized actions and JSP's that can handle any type of entry? I'm not sure how understandable my question is, or if it's a stupid question, but I want to get this figured out before I spend too much more time on the 'edit' functionality.

Hi there,
Actually when you are looking at the stuff done in the JSTL
all three ways pretty much work, because it contains a
scripting language ;).
Are there any plans on integrating it within Struts? I like
both libraries very much, and I recall a discussion was going
on a while ago about it?
If it is done this would make it is either:
1. property = all I want to write
2. property = %= java expression %
3. property = ${myRadios[param.index]}
My current thinking is that we'll make some variant of #3 available in
Struts tags, in a release after 1.1. But this will primarily be as a
transition tool -- subsequent releases of Struts will be designed such
that you should use JSTL tags directly, as opposed to the
corresponding
Struts tags in the bean and logic libraries. For the html tags,
we'll end up with JavaServer Faces tags when it's released.
(here with 'index' as a request variable ;))
Manfred.

All suggestions are welcome Eddie.
Your idea and your argumentations are good, but your proposed
solution doesn't work :-(
Explanations :
In a taglib property you can use either a string value or a
RunTime Expression (if allowed in the TLD).
If you use a string you have something like : property=all
I want to write
If you use a RT Expr you have something like :
property=%=java expression%
The tag libraries interpreter verify if the content of the
property begins with %= and ends with % . In this case it
suppose that it is a RT Expr and values it. In all other case
it supposes that the content is a string.
With your suggestion, property=myRadios[%= index %] the
tag libraries interpretor see that there's not %= at the
begining and % at the end. Then it passes the value
myRadios[%= index %] as a string to the taglib.
When the taglib get the content of property, it will analize
it and see that it is a indexed property because of [..] but
won't be able to interpret it and will launch an exception like :
java.lang.IllegalArgumentException: Invalid indexed property
'myRadios[%=index%]'
However, it is important to say that your advice is totally
good if you want to use a dynamic value in standard html tag.
I you have another idea to clean my code, don't hesitate to
propose it.
Arnaud.

He has looked at his ActionForm code to try and determine is there is a second setter somewhere (he even looked behind the grassyKnoll() method) but found nothing. Old McAndrew has been known to occasionally miss things that are right under his nose however, and will continue to look. There ARE however multiple getter methods, or to be precise there is a method getHeaderTransform() and an isHeaderTransform() the latter of the two returning a boolean. (The other similar fields also have these but they still work.) Despite their protestations to the contrary, having two getters like this is also a violation of the rules (the JavaBeans rules, that is).

He changed the name of the field on his html form to headerTransformationx , he also added a second setter named setHeaderTransformationx to his actionform and then tried again. Amazing!

After all, a property named headerTransformationx is completely naive and innocent about the existence of any property named headerTransformation. Just to test he renamed the field back to headerTransformation and sure enough nasty Mr Struts gave it the cold shoulder again. Now Andrew is very confused.

Advantages of Container-Managed Authentication ??
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 __ Do You Yahoo!? Yahoo!

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. 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. Could someone shed som light on this? Regards, Jens Stutte Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

McClanahan [EMAIL PROTECTED] wrote: If you are using container-managed security, you either declare a security constraint (to force a login) or you don't -- there is no middle ground. However, if the user went to your second sub-app first, and then went to the first one, the fact that they have logged in is visible to your application, because getRemoteUser() will still return the logged-in user's identity. 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. There is no such mechanism that is portable across containers. If you want to use container managed security, you should architect your application inside its boundaries -- otherwise, you should roll your own. 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. 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. Quite frankly, I'm not convinced your use case is very compelling, but I undoubtedly don't understand the whole picture, either. 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. 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.

RE: html:form weirdness in Websphere 3.5.5
I see... I don't know why you're using html:form action=login ... 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 html:form action=/do/login ... in your JSP, then you won't have to worry about forwarding or any of that other stuff you're doing.

I have another question for anyone that could give me some input on it. I'm working on a data entry application, and the user can make three different types of entries. Let's call them A, B, and C. They each have some form fields in common with each other, but each has a couple unique fields. To add an entry, I have a separate JSP for each, and different action mappings for each (that all refer back to the same action class). This works fine. Now I'm working on an edit function for the entries. I have a link within a logic:iterate tag that displays a link to an edit form. I tried using one action and one JSP for the edits, but it gets very messy trying to allow for the different types of entries. Is it a bad idea to use lots of different action mappings and different JSP's for each operation for each type of entry, even though they are similar and all have to perform very similar operations? Or should I go to great lengths to make very complex generalized actions and JSP's that can handle any type of entry? I'm not sure how understandable my question is, or if it's a stupid question, but I want to get this figured out before I spend too much more time on the 'edit' functionality.

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. 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. 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. 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.

You should generally use Strings for your form bean properties. When you validate it, check to see if the numbers were entered.

RE: What does locale=true really do?
Unless the application overrides it. However, AFAIK, containers will all implement ServletRequest.getLocale() in terms of the highest priority 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 html lang=ja, 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 html lang=ja makes sense. Otherwise, it is a mechanism that create a false information, and is rather harmful than useful. language listed on the Accept-Language header -- that's what Tomcat 4 does -- so this represents the *requested* language unless the application changes to something else. Is there anyway for Struts application to call setLocale on the request object before it constructs Content-Language header? -kuro -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

[OT] Keystrokes
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?

RE: Form not keeping changed values
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
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.
Thanks for your help.

Newbie Struts requirements question

Re: Problem with session ojects: memory size, updates
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. Heligon Sandra wrote: I read Value Object pattern on J2EE design pattern http://java.sun.com/blueprints/patterns/j2ee_patterns/catalog.html. I understood that JavaBean are an implementation of ValueObjects. a value object represents a business object, but it doesn't need to provide business methods on top of its data; it only provides methods to read its data, which makes it an ideal candidate for local access rather than remote access. So I don't understand your remark Another possible solution is to create Value Objects and serialize them. Did you want to say that EJB is a solution? Because we don't want to work with EJB. In my architecture I get data from an enterprise back-end system and then Action class create Value Objects(JavaBean) if the object required doesn't exist. If I need to update data on the back-end server, then a manager is in charge of serializing and sending JavaBean across the Network. But to maintain user information (JavaBeans) over multiple requests and pass data between Action and JSP I need to store ValueObject in a cache(session or request scope).

Re: the context
Sounds like Deep Thought you're dealing with there. Similarly to Magicthighs and Broomfondle, you have unfortunately not defined your question enough and the answer would take 7.5 million years to formulate. Adolfo Miguelez wrote: Hi All, we are are developing a framework based on Struts, and adapting Struts to a propietary middleware which, in turns, as usually, deals with the backends. Struts would make up the presentation layer, more or less, delegating in other layers for the business stuff. It has been suggested a patter model, which I did not know before, and, approximately, it is based in a XML which holds all the application data in a tree structure grouped by functional roles. In that way, the data is not spread all around the app, but it is wrapped in this functional abstraction. It could be seen as a central structure for holding all the model (and i.e. the state) of the app. It is termed THE CONTEXT Actions fills the context, and send it to the middleware, which, in turns, sends it to business layer. It has empty fields for the data that has not been obtained yet (actually all the app data is wrapped inside the context). Business layer fills the new data into the context, and the whole context is sent back to the action which, in turns, extract the output data from it to fill the value objects and send this to the JSP for rendering. Well, we are having actually, quite a lot of problems in integrating this new element with Struts, with the ActionForms, with the validator. It is actually as a huge value object holding all the data of the app, travelling forwards and backwards along the app layers. My questions are: - has any of you seen a similar pattern? Any pointer is welcome. I do not identify anything in the GoF patterns, but maybe I am not realising of some of them. - what is your opinion about it? - could Struts, in future releases, include a context for wrapping the data model for the app?

Re: Related Select lists
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.

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

CRM Setting stuff like this up in the reset() method is the standard approach.
CRM Arrays have to exist already for either standard JavaBean-based
CRM ActionForms, as well as DynaActionForms.
I'm still a bit confused by this. When I use a standard
ActionForm I don't have to do anything special with my ArrayList
in the ActionForm. A page that uses this ArrayList works fine.
However as soon as I try to use this ArrayList as property in a
DynaActionForm I run into problems trying to submit a jsp page
that was populated with the ArrayList info (the display works
fine, it's just upon submission).
If you're using request scope beans, a new instance gets created on every
request. And I will bet that you probably have an initialization of this
array happening in your constructor, or in an initialization expression,
right?
For DynaActionForm instances, the default initialization of all
non-primitives in null. That's why you still need to initialize in
reset(), or use the new initial property described below.
CRM In recent nightly builds, we added support for an additional mechanism --
CRM you can declare an intiialization expression for arrays in the
CRM form-property for a DynaActionForm bean, using the initial attribute.
CRM The syntax is basically like what you use in Java to initialize an array
CRM to a set of values in a variable declaration -- for example:
CRM form-bean name=myform
CRM type=org.apache.struts.action.DynaActionForm
CRM form-property name=intArray type=int[]
CRM initial={ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }/
CRM /form-bean
What if the information in an ArrayList of beans that you want in a
DynaActionForm is to first be populated by some database info.
Do you need to first initialize it like a above to a bunch of
nulls? If so what if the list size fluctuates (hence use of
ArrayList) how do you know how many to initialize the ArrayList
with?
That's definitely a place where loading the arrays in the reset() method
makes sense.
Having an intArray property of type int[] on a DynaBean is very much
like having the following method signatures on a standard JavaBean:
public int[] getIntArray();
public void setIntArray(int intArray[]);
so you don't have to pre-initialze the array to nulls or anything. Just
set up the array you want as a local variable (of any desired
length), populate its values, and call:
int intArray[] = ...;
dynaform.set(intArray, intArray);
One really common scenario is that you don't know ahead of time how many
items you're going to read from the database. An approach I use a lot is
to use an ArrayList to accumulate the values, then convert them to an
array. Something like this (assuming you have a labels property of
type java.lang.String[]):
ArrayList temp = new ArrayList();
Connection conn = ...;
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(select label from customer_types);
while (rs.next()) {
temp.add(rs.getString(1));
}
String labels[] = (String[]) temp.toArray(new String[temp.size()]);
dynaFormBean.set(labels, labels);
Alternatively, you could set your property type to java.util.List instead

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

CRM Not any rougher than it is for people trying to understand standard CRM ActionForms :-) Correct me if I'm wrong here Craig, but where I noticed it was quite a bit more difficult is when you decide not to use Session scope for FormBeans that have ArrayLists with beans inside that also have ArrayLists (etc. with nesting ). I say this because if I remember correctly isn't one of the main differences between the DynaActionForm and the standard ActionForm is that the DynaActionForm ALWAYS calls the reset method (regardless of scope) whereas the ActionForm only calls it when in it's in request scope (or explicitly called?). This is where I think I was running into trouble, since even though my DynaActionForm had session scope it was always calling reset whereas my standard ActionForm in session scope was not calling it. That's not quite accurate. Struts (all versions) always calls reset() when you flow through the controller servlet. However, if you went directly to a JSP page, and the html:form tag creates the form bean (quite common if the form bean is defined to be in request scope), Struts 1.0 did not call reset() but Struts 1.1 does. In the 1.1 case, it makes no difference at all whether it is an ActionForm or a DynaActionForm. So in my case if I wanted request scope for the ActionForm I still would have had to override the reset method to provide a way to initialize the ArrayLists (and I take it the beans inside with ArrayLists as well). That is true for both kinds of beans. In either case, you can also choose to make the constructor do this sort of initialization (requires a DynaActionForm subclass in the dynamic case, but it's still possible). In my case however it's not too big of a deal that this UserFormBean hang around for a while with Session scope so it seems much easier to use it with an ActionForm than with the DynaActionForm (since with the later case I'm forced to override the reset method and populate nested beans). That should be the case for either kind of form bean. Can you show me an example of where it's different? This is probably a dumb question and I suppose I could try it before posting, but what would happen if I just wanted to use the DynaActionForm in session scope and then just overrode the reset method to do nothing? You'd mess up the initializations based on the initial attribute :-). Wouldn't it still keep the values in the DynaActionForm since it had session scope and wouldn't try to set up unitialized ArrayLists, etc? (of course this would only help if the bean was in Session scope..but just curious if it would even work). Thanks again for all of your comments so far It might do what you want, but for the wrong reasons.

RE: Good/Bad Practices
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 -Original Message- From: Kamholz, Keith (corp-staff) USX [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 18, 2002 9:58 AM To: 'Struts Users Mailing List' Subject: RE: Good/Bad Practices Yeah, that's what I prefer too, but I didn't know if having a shitload of JSP's and action mappings meant that I was doing something wrong.

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. /mark -Original Message- From: Kamholz, Keith (corp-staff) USX [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 18, 2002 9:32 AM To: Struts (E-mail) Subject: Good/Bad Practices Hey everyone, I've been trying to get in the habit of using good struts programming practices, (without making things too hard on myself). I have another question for anyone that could give me some input on it. I'm working on a data entry application, and the user can make three different types of entries. Let's call them A, B, and C. They each have some form fields in common with each other, but each has a couple unique fields. To add an entry, I have a separate JSP for each, and different action mappings for each (that all refer back to the same action class). This works fine. Now I'm working on an edit function for the entries. I have a link within a logic:iterate tag that displays a link to an edit form. I tried using one action and one JSP for the edits, but it gets very messy trying to allow for the different types of entries. Is it a bad idea to use lots of different action mappings and different JSP's for each operation for each type of entry, even
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 :) Chuck At 03:13 PM 7/18/2002 -0500, you wrote: Chuck, Any word on your expected publication date yet?
