Model 2 based framework for .NET released - Totally OFF TOPIC
Hi. Sorry for this, hope nobody gets mad at met. But I'm pretty sure there are people here that also work with .NET. So... I've worked in a MVC (Model-View-Controller) framework for Microsoft .NET Web applications. The framework has now been released and is in Beta version. The framework is based on Model 2 from Sun Microsystems, hence very similar to Struts (actually it's inspired on Struts), though it's a lot simpler. Microsoft .NET provides a nice object model and a event based system, so the final result of using this new framework is close to what JSF (Java Server Faces) proposes. I'm looking for some comments, opinions, ideas, bugs, sugestions and critics. The project is supported by SourceForge and is available at http://sourceforge.net/projects/lattis/ or at http://lattis.sourceforge.net/.

RequestProcessor instantiation doubt ( in .NET)
Hi all. The last days I've been working in a Struts like framework for .NET. I guess most people that work for companies that develop both in Java and in .NET whish they had something like Struts for .NET projects. The framework is almost ready (when I finish and publish it, in few days, I'll send an e-mail to the list). My framework is a lot simpler than Struts. Although I got a lot of ideas from Struts, it's not that similar when we talk about coding. And here's comes my question. In Struts, when a http request hits the ActionServlet, it delegates to a single RequestProcessor instance to handle the request. There's only one RequestProcessor instance per module in a Struts application because this instance keeps a lot of information about actions, module config, etc... In my framework, when a http requests hits my Front controller it delegates, in the same way as Struts, to the RequestProcessor. However the RequestProcessor is not responsible for keeping application configuration information. Basically, I get a singleton class wich keeps all this data. So, is it necessary for me to have only one instance of the RequestProcessor??? Or should I just instantiante one RequestProcessor for each http request that hits my front controller What would be the impact on performance for both approaches??? Well, that's it. I'm looking to hear some opinions on that. Thanks all and sorry for using Struts list for this, but I really think it's here i can get the best information. Leandro __ Do you Yahoo!? Yahoo!

RequestProcessor never assigned in ActionServlet.
Hi. Why does the ActionServlet has a RequestProcessor instance member that never gets assigned? The point is that the ActionServlet uses the RequestProcessor created by RequestUtils and never assigns it to it's instance member. I check this out in 1.1 and 1.2.4 source. Any comments? ___ Yahoo!

Synchronization in request processor may cause performance impacts????
Hi. I was taking a look at struts source and found out something new (to me, of course). I knew that the RequestProcessor is the one that acutally handles the request. Although it makes sense, I didn't know that the method getRequestProcessor() in the ActionServlet was synchronized. Has anyone "measured" any performance impact that may be cause by that?

RE: Initialization sequence diagram
Hi Martin. I've already got Struts in Action and also have seen http://rollerjm.free.fr. However, the diagrams avalable overthere don't have the necessary details I need. Anyway, until this moment I could get everything I need from the Struts source. Sometimes it takes a little more time, but it's also interesting. I think that in a couple weeks I'll have something useful and let you know. My ideia is not to make a port os Struts for .NET. In simple words, I'd just like to get the MVC 2 working fine (I've already got this, but it's a mess at the moment), what I think is the most important in .NET (having in mind that it already has a nice tag an object model).

Re: Coupling between view and domain model (off topic)
Vic, the separation of view and model is clear on your approach, liked it. However, there`s still one of the coupling i mentioned. Suppose that one year later your client decided to change the information contained in one of the pages. He now wants the all the stuff from 2 pages in only 1 page. You`d probably have to make some changes in your action. As you said, you created form beans based on the html fields. Naturally, the way that the actions manipulate these form beans will change (maybe just a little if well disigned). THis is the other coupling i`m talking about. I`m not saying this is wrong or this is bad modelling, whatever. I`m just asking if there`s a very abstract model where we don`t have the coupling.

Coupling between view and domain model (off topic)
Hi all. This might seem more a design question than a struts specific question. Anyway, if anyone could help me out a little here. I`m going to explain what is my approach for an specific situation, then you tell me what you think about that, ok. When i`m designinig the web interface for a software, i go something like this. Suppose i have a table USER in database and also have 2 other tables that have relationships to this one. They`re table USER_PROFILE and USER_ADDRESS. I`m very used to build CRUD pages, so i usually go with a design like this. I got, for example, a UserCRUDPage, where the user can set attributes like name, age, e-mail, etc... that belong to the USER table in db. I also use something like a navigation bar that in this specific case would have 2 links, one for User Profile and other for User Email. This way, if the user wants to set/update his/her address, he would just click on the link and go to the AddressCRUDPage. The same thing would happen to profile. This design seems to be very nice to me. Unfortunatelly, i had an experience last week that made me think about that. I had some Actions associated whith the updates. In this case i had ActionUserUpdate, ActionUserAddressUpdate and ActionUserProfileUpdate. Naturally, this classes performed all the control layer associated with those operations. It doesn`t matter right now if the Actions are in diferent classes or in the same one. If you want, you can think that i actually had a DispatchActionUserCRUD for example. The "problem" started when my client decided that from now on he would like to have the address operation page in the same page of the user page. In this case i had to mix the UserCRUDPage with the AddressCRUDPage in only one page. My client also wanted that all the data on the page could be updated with only one mouse click (in other words, only one 'save' button). Naturally, i was forced to make some small changes in my pages (and it`s forms) and the associated Actions, so now i need to a way of centralizing the operation of both actions (User and Address). Briefly, i need to make a few changes in my Action, that`s the point here. Although the changes were actually small, i started to think that : My view is coupled to my control layer, wich is even more coupled with my domain model. Well, i`m not talking about big coupling here, but it exists. In other workds i`m saying that in more abstract point of view, this is what happens. I really would like to hear comments about this whole thing... Thanks for reading. __ Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search.

RE: Exposing ActionForm and MVC fields
Hi Chris, what do you mean by "interfaces to filter" (sorry for the stupidness)??? Is it an ordinary Servlet filter??

RE: Exposing ActionForm and MVC fields
Hi guys, thanks for your opinions, it seems that both of you stick with approach 2. However, none of you mentioned that "exposing ActionForm fields" problem. Suppose if build then 2 different pages (as you adviced me). I guess my Action for this both pages would still be the same, it will only send the request to 2 different pages depending the type of the company. Usually, i set the jsps pages form`s inside this Action (normally with BeanUtils), what will force me to give the correct names for the jsp form fields (even if they are labels for the case the user cannot alter them). In this case, i`m still suceptible to be hacked by javascript, because of the ActionForm fields exposure. What about that??? --- "McCormack, Chris" <[EMAIL PROTECTED]> escreveu: > +1 > > You could still create common elements to both pages > which will help maintain a look and feel and reuse > existing code, look at using different tile layouts > for each user type but the elements in the page are > common jsp/tile definitions. > If the spec for one user changes then you could > simply just copy the tile fragment that was changing > to a new location and work on it, then change the > tile definition for that user to point to the > updated fragement. > You would still maintain a majority of common code > and in the long run even if both user views totally > change you can deal with it as and when the changes > happen by copying and altering each tile fragment > that is changing and updating the tile definition to > point to the new fragment. > > Chris McCormack > > -Original Message- > From: Freddy Villalba A. > [mailto:[EMAIL PROTECTED] > Sent: 15 October 2004 11:54 > To: Struts Users Mailing List > Subject: RE: Exposing ActionForm and MVC fields > > > Hi, > > I'd go for approach #2.

Exposing ActionForm and MVC fields
Hi, i'd like to hear some opinions. I got a b2b application. I'm facing a desing problem. This problems is associated basically to 2 themes: - MVC - Exposing AcfionForm fields. I got a page where the BUYER fills a form to buy an specific item. The steps are very simple. 1 - He sends a request for a quotation. 2 - After the quotation, he sends a request for an order. The point is... When the SELLER goes to make the quotation he's supposed to see a very similar page to the one the BUYER filled the information. This is obvious as the information is the same for both parts. So, should i implement the page for the SELLER: ==>>> APPROACH 1 - using the same exact page as the BUYER for the SELLER. Then i'd make the fields the BUYER filled disabled (or just make them labels) using some kind o scriptlet like this. .../> , where sellerVisibility would be something = "disabled=true" This approach seems nice to but i'd say that it's just not that cool!!! It doesn't look nice from an MVC point of view. I'll take the risk of having a lot of this kind of scripts in pages as the times goes by. I know that the Action (control layer) is actually responsible for setting the "sellerVisibility", what means that it's also not that bad from the MVC point of view. But any way, the major problem with this approah is that i use BeanUtils to copy data from the ActionForms to the VOs and vice-versa. So even with the fields disabled, i would take the risk of some smart guy cheatting and setting via javascript the fields he's not supposed to set. And as i copy the data with BeanUtils, my data will be changed when it's not supposed to do so. > APPROACH 2 - just create another page for the BUYER. This page would look exactly the same for the BUYER and the SELLER, but they'll be different pages. This way, i can build this other very similar page without exposing my ActionForma attributes. This approach seems to me allright from the MVC point of view. But the problem of this approach is that i'd start building some kind of redundant and duplicated code. Any opinions...

Kind of out of topic, but... AOP in j2ee
Hi, sorry for the kind of out of topic message, but i'm looking for some information that developers like the ones in this list may help me a little. I'm applying for a master degree (M.sC) and i need to have a project sumary, something like a "project idea" for start up. I've heard a lot about AOP (although i'm not very familiar with it yet) then i thought i could submit a project proposal about AOP, but i don't really know what could be a good idea! Instead of AOP i could also submit a proposal about design patterns and agents. Well, i'm just completely lost. If anyone could give me an idea...??? May be a stupid one, but would be probably better than mine. Thanks, ltcmelo __ Do You Yahoo!? Tired of spam? Yahoo!

RE: ActionForm data type X BeanUtils -> using Dates
I was taking a look at bean utils source and could see
myself how this is done. Then i understood that
acutally you use the
value instanceof SOMETHING
However, the BeanUtilsBean class is quite complex and
i didn't have the patience (and the brains) to try to
understand it.
Anyway, it seems to me that when the "value" goes to
the convert method it already has a defined data type
(that's way the instanceof). But can anyone tell me
how exactly is the flux of data?? When does exactly my
"value" assumes the destination type???

Yes Jim, "to convert a String to a Date", so if i use
value instanceof Date
i will allways fail!!! Because value is a String, you

Re: ActionForm data type X BeanUtils -> using Dates
I got one doubt in your code when used in a situation
that i mentioned (transforming data from action form
to dto).
When date comes from action form, they usually come in
Strings, but in your method you verify
value instanceof Date...
This will never happen, as the value comes in String.
Am i saying something stupid???
I'm not saying your code is wrong, but not appropriate
for the situation in question.
Am i right?

RE: ActionForm with all application attributes
Jim, all the code i`m talking about is inside a Base Action Form. It seems the you`re thinking that my code is inside a action, aren`t you?? Maybe a misundertanding, maybe mine, maybe yours. So, i agree with some of your comments, but not on all of thems. In fact, i`m gonna to take a look about this customized classes to use with validator. --- Jim Barrows <[EMAIL PROTECTED]> escreveu: > > > > -Original Message- > > From: Leandro Melo > [mailto:[EMAIL PROTECTED] > > Sent: Tuesday, September 07, 2004 5:48 PM > > To: struts jakarta > > Subject: ActionForm with all application > attributes > > > > > > Hi, > > i sent this question yesterday, but as nowbody > > answered me, i trying it again with a more > > sifinificant title (sorry for the re-post). > > Also, if i'm doing something terrible, i'd like to > > know. > > > > Keeping in mind that more than one action form may > > have to validate and/or reset the same fields, i > > decided to this. > > > > I already have a MyBaseActionForm which > incorporates > > all > > some methods that i need in my application.

ActionForm data type X BeanUtils -> using Dates
Hi, i believe that a lot of developers use BeanUtils to copy the data from ActionForms to the specific DTOs. I've used this approach, but right now i'm facing a problem, not a big one. I've allways been confused about working with dates in Java. I got a jsp where the user must input a date in the following format. Date: dd/mm/ That's how we use dates in Brazil: the day, month and year. I'd like to make a validation if the user input the date in the correct manner in the ActionForm (i'm using traditional validation and the user input comes in a String). So, keeping in mind the variou ways of doing this date validation (even the deprecated ones), how should a do the date validation Which one is the best way??? I just want to check if the user input a day with 2 digits, a slash, a month with 2 digits, a slash and a year with 4 digits. Also, after that i'd like to copy this form data to my DTO with BeanUtils. Which type should i use in my DTO for this date??? Thanks, Leandro. ___ Yahoo!

Re: ActionForm with all application attributes
Bill, wait a minute, i just thought on something. I wouldn't matter if a hacker set a attributes in my BaseActionFomr, if i don't use it to build my DTOs. I mount my DTOs case specific, so i'd just ignore the hacker set attribute. But if this hacker set attribute is in my DTO, i agree that i could get problems. But if this attribute is present in the DTO it means that even if i was using the traditional way this attribute would present in the traditional ActionForm and, consequently, would be suceptible to the same problem.

Re: ActionForm with all application attributes
Bill, this is for sure a disadavantage. Do you see others Actually, we're suceptible to this avantage in all forms, but i agree with you that if i have a base form with all atributes the chances of things getting messed up is a log bigger. --- Bill Siggelkow <[EMAIL PROTECTED]> escreveu: > Are all of your getters and setters public?

ActionForm with all application attributes
Hi, i sent this question yesterday, but as nowbody answered me, i trying it again with a more sifinificant title (sorry for the re-post). Also, if i'm doing something terrible, i'd like to know. Keeping in mind that more than one action form may have to validate and/or reset the same fields, i decided to this. I already have a MyBaseActionForm which incorporates all some methods that i need in my application. I don't use Validator, as i prefer to use java classes for validation ligth business logic. Now, i decided to add ALL fileds (setters and getters) i have in my application as private members of this MyBaseActionForm. Then i created classes WebValidation and WebReset. This classes have validate methods for all fields in my application. These classes can access the fields they need for each method because all my action forms extend the MyBaseActionForm, thus this WebValidation and WebReset classes can call the setters and getters of an y action form to validate with the light business logic i need. I got with this approach a centralized way and "component" responsible for the validation. All my action forms delegate the validate and reset methods to the classes i mentioned. I'd like to briefly describe some nice benefits of this approach. - With this approach i definetly solve my earlier problem that i posted on question "1:N relationships - ActionForm x DTOs". - With this approach i got no coupling between my ActionForm and DTOs. - With this approach i have a centralized validate unit. It's very usual to have more than 1 action form validating the same field, what may causes some duplication and a harder maintenance. A central unit of validation and resetting suits this problem very well. - With this approach i can perform light business validation that must be done in java code. So, for one or more situation i could access some util classes that do some validation for me. - With this approach i have very small action forms that basically has a validate and reset methods that just delegate to the WebValidation and WebReset classes. - With this approach i also have a central unit of fields and their types, so if it's necessary to chance them, i don't need to go through all the action forms that have these fields. This approach will only work correctly if you don't have fields with the same name in your application. Naturally, this is not a drawback because forces you to use a nice use of software engineering forcing you to give significant names for the fiels. Well, i'd appreciate comments (bad or nice ones) on that. Thanks, Leandro ___ Yahoo!

1:N relationship - ActionForms x DTOs
hi, unfortunatelly i got my action forms coupled with my DTOs . This is a very common disucussion in which i don't want to go to the merits of it right now. I just need a solution for a specific problem, but if this solutions requires going back to the first point, it's ok. I'm used to have jsps that are "coupled" with my dtos, so for a page in which the user regiter data about the company, there's a CompanyDTO object that will transfer the data from the Action to the persistent layer. Also i have an analogue ProjectDTO which transfer data from Action to persisten layer. The page used to register a company has a form bean with fields that matches the CompanyDTO data type. The page used to register project data has a form bean with fields that matches the ProjectDTO. Now, i have a new page for user to input data about the company and it's projects. A better approach would be building a "new" form bean and a new ActionForm with both the company fields and the project fields. Naturally this "new" form bean and ActionForm would like just the same as the CompanyActionForm + ProjectActionForm, so i thought if there's a way i can reuse my ProjectActionForm and my CompanyActionForm to build a CompanyProjectActionForm without having to go with all the fields one by one for this action Form. Is there a way to do that??? So i would have an CompanyProjectActionForm "composed" by two other ActionForms, instead of having to write a whole new CompanyProjectActionForm. __ Do You Yahoo!?

struts exception handler
I got this from struts page.
"Don't throw it, catch it! - Ever used a commercial
website only to have a stack trace or exception thrown
in your face after you've already typed in your credit
card number and clicked the purchase button? Let's
just say it doesn't inspire confidence. Now is your
chance to deal with these application errors - in the
Action class. If your application specific code throws
expections you should catch these exceptions in your
Action class, log them in your application's log
(servlet.log("Error message", exception)) and return
the appropriate ActionForward.".
But what about struts mecahnism of handling
exceptions? I`m really used to throw exceptions from
my actions and let the configurabled exception handler
(i actually use the default one) take care of the rest.

How long is Action's scope?
Hi, for how long will an Action be in memory? Here's the point. I have a situation where the user register his/her company in my application. He/she uses a wizard of 4 jsp pages, as he/she submits one, he/she is redirected to the other one. In this situation i keep a reference of my Stateful session ejb in HttpSession so the 4 Actions can reference them to complete the wizard. This is pretty much fine to me. BUT..., now i'm facing a new question. I have a similar situation where the user can submit the page more than one time, and it is always the SAME aciton the will handle this request. It's a search page, so the user can search once, search again, search even more, and it always the same action the will handel this (behind the scenes a i got a business POJO that implements the ValueListHandler pattern). For this case i also have a Statefull session ejb that maintains a reference to my business POJO (the one that implements the valueListHandler). Obviously, this Statefull sesison ejb is accessed by this one Action that i've been talking about. My question is: In the first situation i mentioned, i had to save a reference to my Stateful session ejb in HttpSession because 4 action would need that reference. But what should i do for the last situation?? Only one Action will handle the user requests, so can i ASSUME that this Action will still be in memory for next requests and consequently this Action will still have a reference to my my Statefull Session ejb (naturally, this reference would be a member of the action).??

Re: LookupDispatchAction (Newbie)
Michael, i`d preffer to do it the way i described.
Having all "submit" buttons with the it`s name beeing
"method" por exemplo, and then checking if the return
of getName() is null. If it is ->
String methodName request.getParameter("method")
dipatchMethod(..., methodName);

RE: LookupDispatchAction (Newbie)
I gues the point of the ImageTagUtil class is specially for use with "submit" image buttons. However you can do build your wokraround for use in any cases. In my case for example, here`s what i do. In my application, i decided to make of my submissions that go for Actions must have the parameter "method=nameOfMethodToBeCalled" in the cases the submissions don`t came from image buttons. Then i if the ImateTagUtil class returns null for the name of the button, i get the parameter "method" and dispatches to the specific method. --- Paul McCulloch <[EMAIL PROTECTED]> escreveu: > I'm confused.

Re: LookupDispatchAction (Newbie)
A quick look at the DispatchAction source (if you don`t have the source, you can download it) would the best way for you to understand. It`s not that complicated. I never took a detailed look at the source, but basically, it gets the mapping for the method specified in struts-config.xml and then get the value of this parameter. After that it dispatches the request to the specifc method a calling to dispatchMethod() method. --- "Varley, Roger" <[EMAIL PROTECTED]> escreveu: > Hi > > I have implemented a LookupDispatchAction action > class to deal with a form that contains multiple > submit buttons as outlined in the sample chapter > from "The Struts Survival Guide" at > http://www.objectsource.com/Chapter4.pdf I've got > everything working but I would be grateful if > someone could either explain or point me to > documentation explaining, *why* it works? > > Regards > Roger > > > __ > This e-mail and the documents attached are > confidential and intended > solely for the addressee; it may also be privileged. > If you receive this > e-mail in error, please notify the sender > immediately and destroy it. > As its integrity cannot be secured on the Internet, > the Atos Origin group > liability cannot be triggered for the message > content.

Re: Struts login with JAAS (Part 2)
You don't need to learn, it's an option.
If you need a secure system though you may want to use
some kind of authentication and authorization service.
You can learn just a little of JAAS which is enough to
use container managed security, or you can write your
own security mechanism (using or not jaas).

Re: Help with Cactus StrutsTestCase
Sorry for the confusing sentence.
I meant to say that i don`t know the answer, but i`d
like to use the opportunity and also ask a basic
question.
Where can i find a good
tutorial do test struts applications?
Is it true that for good testing the actions must
delegate their work to POJOs ??

Re: ActionForm and Transfer Object
Rick, i agree with you, i also use BeanUtils to populate my forms. But, this doesn't go far way from having your ActionForms dependent on your TOs (or CustomTOs, doesn' t matter). As Sebastian said, i've heard a lot that TOs should mirror or shouldn't be coupled to your ActionForms, but i really don't how it's possible to build a very modular architecture without this coupling. --- Rick Reumann <[EMAIL PROTECTED]> escreveu: > Sebastian Ho wrote: > > > > > Say I retrieve a TO from database and convert it > into a actionForm for > > display.

Weird message when redirecting
I'm working on a login module, wich because of JBoss/Tomcat way of handling JAAS it has some redirections on the way. I built an action the does some stuff for me and then returns an ordinary forward. I decided to set redirect="true" in this forwared just to make sure that the user sees the correct page on the browser's url input (in my specific case, i don't have reasons to send a forwared instead of redirect, if i should do i forward or a redirect doesn't matter very much at the moment). Keeping in mind that this is part of the login, i really would like for the to see the index.jsp (wich is the one i send the forward to) rather than some other page that he/she requested. As we all know, if i use redirect="false" (the default otpion) the user would see some other page name in the address bar of the browser, and not index.jsp. But, when i try to make the login, here's what i got from Mozilla Firefox. "Redirection limit for this URL exceeded. Unable to load the requested page. This maybe caused by cookies that are blocked." In Internet Explorer the request just doesn't complete. Naturally, if i take out the redirect="true", everything works fine. I know that when we use redirect="true" it's necessary a reconnection between the browser and the application, but why exactly i would get these errors for using more than one redirect in a single request. It's not possible for me to know exactly how many redirections are going on, because Tomcat that really handles this request by itself. However i'd guess that they are two by default. After i added my own redirect for one of my actions (as i described) they become three. Any comments on that??? __ Do You Yahoo!? Tired of spam? Yahoo!

I'm no expert here, but i think you're gonna have to deal with the tradicional and ordinary file button as it comes. In other words, i don't think it's possible to use an image for this button.

JAAS, JBoss and Struts review. Erik, now i get the point !!!
Hi, i've been trying for days to make this thing work. I googled the web for many tutorials and documentation, i read Scot Stark review, and lot other stuff. Unfortunatelly, i guess i didn't make a good search right here on the struts mail archive. I if i've done i'd have found this very explanatory discussion (by Erik, Craig and others). http://www.mail-archive.com/[EMAIL PROTECTED]/msg07533.html Maybe it was because of english interpretation problems, by i couln't still figure out (in the earlier posts) what Erik was trying to tell me, but now i do understand!!! Erik, now i'd like to now if could work out a "final" solution for your problem? From one of your last posts, i remember you saying that you haven't worked on the "security integration between Tomcat and JBoss", so i'd guess you're still working with the j_security_check thing, aren't you? If you're still sticked with the j_security_check action, i have one question number 1 for your, but if you're not working with j_security_check anymore and found out a better work around, i have question number 2 for you. 1 - Suupose a user ruquests page http://www.EriksApp/someOtherPage.jsp of your application instead of requestion the http://www.EriksApp/index.jsp (or just http://www.EriksApp). First, the user will be redirected to the login page (assume that all your application is secure). Second, if login was sucessful, he'll be redirected to http://www.EriksApp/someOtherPage.jsp and NOT to http://www.EriksApp/index.jsp, because Tomcat saved that first request. But I'd like to have a forward to SetStuffAction.do in my index.jsp, so i can set user information in this SetStuffAction.do. But if the user is redirected to http://www.EriksApp/someOtherPage.jsp instead of http://www.EriksApp/index.jsp, he/she will bypass that step and won't get their stuff set. How do you "solve" this (a filter, or something else)??? 2 - Well, if you get the whole thing working without the j_security_check thing and with a "logonAction", would it be possible for you to send me some code???

Re: Struts login with JAAS (Part 2)
Hi Erik, i was not missing that, i just forgot to tell
you that...
- JBoss actually propagates it`s security suff to
Tomcat and vice-versa. I got this information from the
JBoss forum
(http://jboss.org/index.html?module=bb&op=viewtopic&t=53202).
Then i tested it myself with a simple login using
j_security_check and could confirm this fact. JAAS is
propagates between JBoss and Tomcat.
Anyway, let`s have some thoughts...
In my logon action, i can log in fine (as i told you,
using JBoss structure) then i forward to the index.jsp
page, wich is a secure page. Then i think that if this
security was not propagated i wouldn`t even get to the
index.jsp, because it`s a protected page. And as i
told you, i reach the index.jsp finely.
So, it seems that i`m actually been authenticated in
JBoss and Tomcat (i`m not home right now, but when i
get there i`ll try to use a request.isUserInRole
method inside that action to confim my thesis), but
only for a request scope.

Struts login with JAAS (Part 2)
I'm back!
After getting some jaas studies, i'm a little bit
better, so i can now formulate a better question.
Here it is... (I know that this is not only a Struts
question, because it envolves jaas, but i'm pretty
sure that people over here could give me some advise
on how to handle the problem).
I got my application protected with JAAS, so users
cannot access any pages or servles withou a login. I
build then an Action to handle login stuff.
Heres the code of my LoginAction (execute method).
//...
String j_username =
(String)request.getParameter("j_username");
String x = (String)request.getParameter("j_password");
if (x != null){
j_password = x.toCharArray();
handler = new UsernamePasswordHandler(j_username,
j_password);
}
LoginContext lc = null;
try {
lc = new LoginContext("example2", handler);
lc.login();
//this part doesn't matter very much
Subject subject = lc.getSubject();
Set principals = subject.getPrincipals();
Principal user = new SimplePrincipal(j_username);
principals.add(user);
} catch (LoginException e) {
// TODO Auto-generated catch block
e.printStackTrace();
throw new Exception();
}
return mapping.findForward("index");
The above code runs perfectly! It logs the user
correctly and then i'm forwared to my index page.
[b]But[/b], when i get to index, everything is gone!!!
I'm not logged anymore. If i try to access another
page in my application, i'm redirect to the login.jsp
page again!!!
I heard that this is because the multi-thread
characteristic of the servlets, but
How can i workaround this??? how can i make this
maintain my login through the rest of my session???
Here's a piece of login-config.xml
java:/DefaultDS
Select
Password from Principals where PrincipalID
=?
Select Role
'Roles', RoleGroup 'RoleGroups' from Roles where
PrincipalID =?
Thanks and regards,
Leandro

Thank you very much for your time Erik, i'll try to get some study around it!!! I don't know if it's possible (probably not, i know...) , but if you could send me your LogonAction class (and associated stuff) would awsome!

Re: Security - From tradition to struts
Erik, i don't quite understand what you call a hand-rolled java component (maybe because of my english). Anyway, it seems to me that you're not using JAAS to completely control application's security, are u? I don't know if it possible, but if so, would you post your setup and basic classes? I'm very very new at security stuff... Anyway, i cleared out a lot of things for me.

Re: Security - From tradition to struts
So Erik, is it a common and usual aproach to do login
outside of Struts (ordinary jsps), and then use Struts
afterwards???

Re: Security - From tradition to struts
Just complementing my question...
Would it be fair if i copy JBoss'
DatabaseServerLoginModule code and place it inside an
Action???
This way, i'll have an Action (for example,
MyLoginAction) that does exactly what
DatabaseServerLoginModule does.

Security - From tradition to struts
Please help me out here!
I'm very new with jaas, so i need some help.
I got a simple login that is working fine for me, here
it is:
...
NOME:
SENHA:
...
I'm using JBoss' default stuff (LoginModule,
CallbackHandler, etc...) to make it works. Here's a
piece of my configuration file (for jboss).
...
example2
{
org.jboss.security.auth.spi.DatabaseServerLoginModule
required
dsJndiName="java:/DefaultDS"
principalsQuery="Select Password from Principals where
PrincipalID =?"
rolesQuery="Select Role 'Roles', RoleGroup
'RoleGroups' from Roles where PrincipalID =?"
;
};
...
As i said, this works fine for me. I only made
configuration and login.jsp, after the user submits
data from login.jsp, JBoss takes care of the whole
thing and already directs the user to index.jsp (in
case of sucessful login).
NOW, i want to do the exact same thing with Struts (my
enviroment is all setup, the only thing i didn't have
was the login module, i already have everything set
and working with Tiles).
The problem is that i don't know what to do, because
i'll probably have to write a Servlet that handles
this request won't i???
Here's in my web.xml
Restricted
Declarative security
tests
/jaas_tests/*
HEAD
GET
POST
PUT
DELETE
Echo
no description
NONE
FORM
/jaas_tests/login.jsp
/jaas_tests/error.jsp
I can start by changing the login page from login.jsp
to login.do, mapping this Action, then what... ???
Thanks,
Leandro

Login and authentication
Hi, i'm building a b2b application that must be released for testing in a few days. I got 1 very basic problem: - I don't know jaas The good point is that i need only a login module to go with Struts and jboss. It doesn't need to be definitie, but it must work. I don't know if by the fact i'm using struts, things should be implemented diferent (as i said, i don't how jaas works), that's why i'm sendind this e-mail. Does anyone know a short tutorial i can use? ___ Yahoo! Acesso Grátis - navegue de graça com conexão de qualidade!

RE: Overwritting RequestProcessor, how to???
Frank, as i said, i only want to call another method
everytime validate() fails. That's the only thing i
wanna do.
If i only overwritte ActionForm and create a
MyBaseActionForm, in my specific forms i'd have to do
something like this inside validate() method.
if (errors != null){
mySpecificMethod();
}
What will cause me to modify all action forms i got.
I thought i'd be simpler if i just overwritte the
request processor and put the above code inside it.
What do you thing now? Is still not the better idea?
I ask because i'm really a beginner, so i don't know
if it would be the best architecture.

Re: Modifying Tiles definitions dinamically
I'm not sure if i get it right, i still have a couple doubts. Take this definition: ... ... Naturally i got a login page, would i have to redirect the login (or just forward the login) to this "TilesAction" and then manipulate my definition and insert the real jsp page i want??? I have never heard of this "TilesAction" (haven`t been dealling with struts for long time), but is it possible to some post some bib reference (or web reference) where i can learn how to work with it???

Modifying Tiles definitions dinamically
Hi, i got a very ordinary problem. I need to provide diferent menus for diferent people that are logged in the application. I don't know what i should do exactly to provide this funcionality, because i don't really know what Tiles allow me to do (i don't know it's potencial). I got the following base tiles definition in my app. One thing i thought is to verify the user permissions at log time, then, depending on the user i'd change the attribute "menu" of my definition to the page menu2.jsp or menu3.jsp, for example. Can (how) i do that??? I also thought on bulding 2 (or 3 or 4) BASE deifinitions and at log time i'd decide which base definition to use. Can i do that (how??)?? I'd appreciate if some show me some reference or just some sample code on how to do that. Thansk, ltcmelo = ___ Yahoo! Acesso Grátis - navegue de graça com conexão de qualidade!

Re: Problems on disabling inputs
I don't get exception Mike, i just get the following
on my page (viewing source from the browser).
instead of getting this.
Then, when the user submits the data, my ActionForm
understands that the input "test" is equals("").
So, it returns some action errors.

Overwritting RequestProcessor, how to???

Re: Who calls the validate method ???
Rick, as i said i really like your approach, but there are some input pages that are really really simple, so there's no need for doing this.

Re: Loosing request attributes
Erik,
i'm not talking about form attributes, that's what i
said in my last e-mail.
I'll try to clear it out.
Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:
request.setAttribute("MyObject", obj);
and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?
Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!
I think now it's clear that i'm not talking about the
formBean attributes, right !?

Re: Losing request attributes
Denis, that's not the point of our discussion. One
more time: I'm not talking about formBean attributes.
Anyway, Hubert pointed a workaroung for my problem.
Thanks.

RE: Loosing request attributes
As i replied many times for this topic, i'd like to
expose the situation again and in DETAILS.
Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:
request.setAttribute("MyObject", obj);
and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?
Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!
I think now it's clear that i'm not talking about the
formBean attributes, right !?

A character decoding problem
Hi, i got a weird thing happening. Actually it's not that weird, it has very sense, but anyway, i would like to avoid that. Ther word "you" in portuguese is "você". I got some error messages like that. error.invalid.name=Vocç deve digitar o nome. What in english would be error.invalid.name=You should input your name. I'm using, as Jim, the following block to catch my errors. When i get the error a described above, here is what the browse page displays: Você deve especificar o nome fantasia. and what i really wanted for it display was: Você deve especificar o nome fantasia. If i take a look at the page's source code via browser, here's the source for that line. Você deve especificar o nome fantasia. As you, it's not what i expected. How can i avoid Struts "decoding" my characters??? __ Do You Yahoo!? Tired of spam? Yahoo!

Loosing request attributes
Hi, when a user request hits the ActionForm's validate method and bounces back, i'm loosing some request attributes that i had set for the page. In other words, if the user inputs some data that don't pass the validate method, the page comes back with a few request scope attributes missing.

Re: Importing context with Struts
Jim,
as i said i have a page with only one line of code,
wich is the error page.
It only has this:
Suppose now we want to register a company in the
application, i got then an form with all the necessary
inputs in a page registercompanycustominforeq.jsp.
Here's the page for registering.
<%@ include
file="/functionalBlocks/companyHTMLcomponent.jsf" %>
The user sees the following definition when he's
filling the company info.
If your remember, the base class ".PartyPlace" has
already inserts the error page.
I don't know what you meant about "WHat scope are
your errors beign put in?". How do i find out that?
The only thing i know is if the user request is
blocked in validation, my html:errors tag doesn't show
anything.
BUT, if i place the html:errors tag inside the page
with the registercompanycustominfo action, it works
fine.
In other words, if i modify my
registercompanycustominforeq.jsp to this:
<%@ include
file="/functionalBlocks/companyHTMLcomponent.jsf" %>
Everything works!!! The errors tag works.

Re: Multiple image tags
Michael,
i think i understand your point now!
If my english let get the point correctly, i realized
that if i have an ordinary Action, and have such
method that finds out what was the value of the image
tag (using your getCommand function) and delegate
(probably with an "if") the processing of the request
to the responsible method, i'll end up doing just what
DispatchAction and LookupDispatchAction does. This way
your solution certainly works perfectly.
Is that it?
Thank you again,

Re: Multiple image tags
Hi Michael,
please correct me if i'm wrong, but none of those
solutions would work nicely in my case.
The problem is that both solutions in a higher level
focus on getting the parameter and checking it out to
see its value.
In my case, i got a MyLookupDispatchAction that
receives all the requests and forwards it to the
specific method. So, there's no meanwhile to get the
request parameter, check it out and forward to some
method.
UNLESS,
i use someking of hidden field in the form with a name
that MyLookupDispatchAction expects:
protected Map getKeyMethodMap(){
Map map = new HashMap();
map.put("hidden.field", "verifyParameterMethod");
}
And the in the "verifyParameterMethod()", i'd use call
"getCommand(HttpServletRequest request)" to check what
was the value of the real parameter i want (the one
from the image tag). Finally, i would compare this
value and forward the data to the responsible method.
Am i correct?
It just seems a little confusing...

Importing context with Struts
Suppose i got scattered pieces of code, wich includes a lot of Struts tags. These pieces are separate files, and i need to accesss some struts attributes (or beans) from these other files for each request. A nice example would be the html: error tag. In my case, it's located outside of the file that contains the submitted form, and i need to get the errors from these other file (where the html: error tag is located). That's why i need to import struts contexts so i can get it done. Is there a way to do that? = _ Leandro Terra C. Melo Eng. de Controle e Automação - UFMG ___ Yahoo!
