changing regexp in default validation
Hi struts users. I'm posting a question on struts validator. Well, as you all know, the struts validator implements an email validation which is defined in the org.apache...StrutsValidator validateEmail() method. (Sorry if the names are not 100% equals to the original ones). Anyway this method uses a jakarta regexp string to validate the email. So now let's suppose i want to change that validation string, as it considers not valid some email addresses which are valid for me. i.e: [EMAIL PROTECTED] I have the validation strings who considers the above email as valid but i cannot figure out where it must be inserted in the validator.xml file to, tell the validateEmail() method to use it insted of the default one. Can someone help me ? Thanx everyone. Ivan. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Tiles Vs Templates
If you use only features from Template, then use only Templates. If you use some Tiles advanced features, then use Tiles. Generally, if you have a very large project with many pages, use Tiles. Tiles allow to build pages by assembling small pieces (Tiles). Usually, you use a layout (or template) to build pages. With Tiles, and its definition concept, you can build all your pages in a centralized xml pages. Furthermore, you avoid repeated work by using an inheritance mechanism. Also, you can use a definition name as the target of a Struts forward. The definition file can be split in several sub-file There are others interesting features in Tiles that you will discover if you play a bit with Tiles.

We have custom renderers that serve up different views depending on the browser type you are coming in with.

Is this feature gone or are they planning on returning it? Basically, I guess I just want to know if the Tiles template will continue to be integrated into struts as deeply as it was in the past. I am also trying to get a feel for if I have to modify the code myself, which we have yet to do, or if I can rely on the standard builds. Thanks for the help everyone ... Sean P.S.

Re: RE: [Fwd: Re: Hi....]]
Hi, The problem with too many tags is one of maintenance. Each tag you write becomes part of your bespoke project 'language'. With large groups producing many tens or hundreds of tags it can become a nightmare for new staff. Far better to stick to the core tags, and struggle not to add many new ones of your own. Think of it another way, each tag is exactly like you adding to html for your own project. Remember the horror of IE v's Netscape when html diverged - that is exactly what a project is doing by writing their own tags. New project members will hate it. BUT, some ten or so custom tags will make your project a joy and there is no downside. OTOH, if its your project, and you don't have to worry about maintenance (!) then do anything you want.

ActionErrors within frames manually forwarded
Hi, I've spent some time checking the list for this issue, but I could only find related topics, that didn't really help. In case that this has been answered before, please ignore it and send me a link. I think that there must be something I've missed when using the Struts validation feature within frames. In short: I'm trying to manually retrieve and forward the ActionErrors within a frame definition page (which is the input page for a mapping). But those manually set request parameters are gone when I access them. The situation is as follows: The page myframe.jsp consists of two frames: mynavigation.jsp and myContent.jsp. myContent.jsp is the JSP that is validated. In case that a validation error (ActionError) occurs, the follwoing (relevant) events occur (correct me if I'm wrong) - Struts puts the ActionErrors I created within validate into the request - a forward to the input page is done as defined in the struts-config (in my case the action entry is: action path=/myContentActionPath type=some.SomeAction name=contentForm scope=session validate=true input=/myframe.jsp forward name=back path=/somePrev.jsp/ forward name=next path=/someNext.jsp/ /action so it leads to the frame page. - within the myframe.jsp, two new requests are created: one for each frame But I think I should still be able to access the request with the ActionErrors within the frame definition page. So in myframe.jsp I could do something like: myframe.jsp: %@ page language=java % %@ taglib uri=/WEB-INF/struts-html.tld prefix=html % html:html head html:base/ titleMyTitle/title meta http-equiv=Content-Type content=text/html; charset=iso-8859-1 /head frameset cols=150,* frameborder=no border=0 framespacing=0 frame src=myNavigation.jsp NAME=Menue frame src=myContent.jsp?manuallySetParam=html:errors property=myErrorProperty/ NAME=content /frameset noframes /noframes /html:html in order to retrieve the ActionError String for property myErrorProperty within the content page: myContent.jsp: ... P %= request.getParameter(manuallySetParam) % /P This - I agree - doesn't look elegant, but at least it should work. If I have the input page defined as a pure jsp (no frames), the html:errors are retrieved as expected. Are there any ideas, why the parameter manuallySetParam does not contain the error message of key myErrorProperty ? Help and/or design suggestions greatly appreciated!

Database Servlet
Hello, I apologize if my question sounds naive but I really need your help on this. I have a servlet that during initialization parses an .xml file using Digester. Then I access the data in my jsps through JavaBeans. What I need to do, is to have my main page which displays the data from the .xml to be updated with the new data each time the .xml is modified. In order to do this, do I have to put the code of the init() method of my servlet in the Action class of the main page or is it a more elegant way to do this? Thank you in advance, Konstantina -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

JRun/JNDI Question
JRun's documentation sucks and it's code examples use deprecated methods.
Does anybody know the correct means to get a JNDI reference to an EJB home
interface from a servlet? I've tried most everything, but what I got before
pulling the rest of my hair out and quitting is a servlet containing, in
part:
Context jndiContext = getInitialContext();
Object ref = jndiContext.lookup( java:comp/env/ejb/CustomerHome);
* * *
public static Context getInitialContext() throws NamingException {
Properties p = new Properties();
p.setProperty( Context.PROVIDER_URL, ejipt://192.168.0.1:8100);
p.setProperty( Context.INITIAL_CONTEXT_FACTORY,
allair.ejipt.ContextFactory);
return new InitialContext( p);
}
The PROVIDER_URL is the port for my JRun Server. The
INITIAL_CONTEXT_FACTORY is what the documentation says is correct, although
there is an InitialContextFactory class in another package. And the JNDI
lookup is in the recommended form. I've also tried the put() method of
Property. No matter what, ref is always null.
A couple of interesting things:
(1) I am not getting a NullPointerException (nor any other error) when
calling the servlet from a browser - just a page with some test HTML output
from a PrintWriter() statement prior to the JNDI lookup;
(2) assert always throws a NullPointerException:
assert ref == null;
assert ref != null;
assert ref.equals( null);
I know this is happening because the Rams lost the SB...Appreciate any
insight(s) you guys may have.

Re: J2EE BluePrints and Struts
Oleg had a pager as part of his BeanFactory, but that was never made part of the framework. Perhaps he will get back to that after the ServiceManager work (Go Oleg!). Generally, these type of model-centric patterns do not need be a part of the core framework. The framework provides places where you can plug into the model (Actions). And ways to pass control back and forth between the View (struts-config elements). But the implementation of something like paging is an excercise left to the developer.

Newbie question: Application Flow in Struts
Hello all, I have a few questions, grey areas, when it comes to application flow in STRUTS. I have read many articles but there are still certain areas I am not comfortable with namely the backend. So let me tell what I think I know and then someone can tell me how I went wrong. When you Submit your HTTP request from the browser it gets handled by the Controller Servlet. This servlet knows to instanciate the proper formBean configured in the xml file. The proper action class's perform() method is called with the previous mentioned formBean as a parameter. This is when I get a little confused. In each of your action classes you initiate the logic to update your MODEL. So for example, myAction.perform() will instanciate/use some business objects to update the state information in the system. Since the perform() method returns and ActionForward object to the controller which I assume the controller will use to show a certain page which is based on a formBean. When should I update/instanciate/set that formBean so that the page that uses it will show the correct info? Should that be taken care of by the MODEL, either an EJB or just a regular bean, or in the Action class itself? thanks, matt lobur __ Do You Yahoo!? Send FREE Valentine eCards with Yahoo!

I plan to tackle many of the more finer-grained issues like request versus session storage, when to forward versus redirect, wizards, etc... I'm going to try to wrap them into real-world, albeit small, examples. As with any book, the problem boils down to space and time. I'm sure that Ted and the other Author doing the Struts book for Wiley are going through the same issues right now. In the end, I won't be able to cover every single topic that involes Struts or web development. It's just not possible to do so. What I have to do is to hit all of the major topics and as many of the smaller ones that I can. OReilly books tend to be more for the intermediate or advanced, rather than the absolute beginner. That's tough because it always leaves a group out, but as someone mentioned to me earlier, you have to cut the line somewhere. Tiles will definitely be a topic and topics like the Struts Console from James Holmes deserve some coverage. The IDE topic is an interesting one and definitely worthy, but it's a question of how do I cover all of the possible IDE's that people use. For example, here at my company, people create, edit, and debug Struts with everything from JBuilder5, SlickEdit, TextPad, vi, and several more. These guys are all good and have excellent debugging skills. I believe that it's true that using an IDE and stepping through code will save debugging time. However, we also don't force a standard IDE down someone's throat as long as they can code and debug fast with good quality. So that one scares me a little. I might be able to select a few IDE's, but someone will always get left out. The good news is that I'm still flushing out about half of the chapters and sections, so nothing is out at this point.

I think that you should have as many references to other complimentary books. Is the EJB section as complete as it can be? How about team based development. Setting up sandboxes, issues with config files. Are you using tomcat for examples? How about some configuration issues with other containers. I am thinking of weblogic... Which tools to use for developing with custom tags (I have hear of ultradev and it's add-ons is good). Other tools -- There have been numerous mentioned in this list -- there was one today about tables and another about struts code generators etc. I also think you should keep in close contact with who the developers are -- I bet they have some great ideas on what to document -- what to expect etc. just some thoughts Sandeep -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Boost Struts with XSLT and XML - JavaWorld.com
I have messed with both Cocoon using XML / XSLT extensively to render views to varying devices and also use the Struts Tiles framework to do the same. I found Cocoon very powerful for static XML documents but as soon as I started trying to hook dynamic content in (forms, JSP's, Servlets, Struts), and NOT through XSP, I was hitting walls daily. However, in Struts I was able to write a custom Tiles FactorySet which looked at the incoming UserAgent and then applied certain rules against that to select the factory. Once that was selected you could write a factory file to have custom JSP's render as the output to actions. I don't explain it all that well but it is actually rather nice. I suggest using this mechanism if you are using Struts and want custom views for each device type. We actually use this user agent mapping factory in every website we develop in our lab. Sean P.S. I am working on getting this submitted back to Jakarta or at least Open Source it ... getting the company to do it isn't all that easy. Matt Raible wrote: Hmmm, I read everyone's posts, and they are somewhat inspiring. I'd like to see examples of using Xalan to get my struts message bundle, or other messag bundles. I'm sure I could spend an hour and figure this out, but if anyone has ready examples, links, send them my way! XForms - I'm excited about these, but I think it'll be awhile before the browser's support them. #3 is probably from my own experience. I spent a week trying to develop a XML/XSL framework using JSPs to emit XML, XSL and the JSTL to do the transformation. My JSPs became very small and nice, but it seemed I was spending a lot of time writing the XSL and trying to get it to work properly. I've had a lot of experience with writing HTML and JSPs, and so I bagged the whole idea and recommended we just use JSP/HTML with Tiles and CSS. I know that my client will get more value from my time with this approach. The reason my client wanted to use XML/XSL was to easily adapt the UI for other devices. I think this is a great reason, but it almost seems simpler to me to separate my HTML client from my WAP client and develop entirely new JSPs for the WAP client. Of course, working with a limited budget and a small development team (1) - there's not much time for learning curve.

Transaction control tokens?
Hi! All
I am having problems using Transaction control tokens.
I am not sure I am using it in the right manner.
This is what I am using in the perform method of my action.
saveToken(request) ;
if (!isTokenValid(request)){
/* specific piece of working code */
}
resetToken(request);
I believe the transactional token is used to validate that
the user does not submit the same form twice. A common
problem is web applications.
The above piece of my code is not helping me do that.
Any help on that issue will be great?
Thanks...Harshal.

Re: AW: Struts/Tiles and nightly build features
It is a entension that we wrote to Tiles to allow custom rendering via routing actions to different views based on the incoming browser type (User-Agent). It is not open source yet ... still working on that. You would use the input parameter of an action to redirect to a certain view when an error occurs in the validation of the form. When an ActionError is returned at that level it never makes it to the Action, it goes back to the input JSP specified in the action mapping.

However, what I now need to do is have these results displayed as a second form, in order to allow the user to select one or more phone numbers.( I'll then need to return to an original page, filling in the selected numbers to an existing form - but I'll cross that particular bridge when I come to it). The thing that's puzzling me at the moment is how do I construct the ActionForm class to cope with a variable number of results?

RE: OReilly Struts book
I'm definitely going to cover some design patterns/strategies related to Struts and EJB. I've been working on an a Struts/EJB application for over a year now and have learned a great deal about how to approach this, so this should be valuable to others. Brian Keeton and I just finished an EJB 2.0 for Que and I will include some ideas we discovered while writing that as well. Someone did point out to me however that obviously not everyone is using EJB and I should give focus to that as well. The banking example is only used in chapter 3, which is an overview of Struts. From the point on, I plan to use other examples. Right now, I'm in the B2B world where orders, items, catalogs, and customers are important. So I might use that domain. Hopefully, I can use various real domains to bring something for everyone. Since I first posted the initial TOC, I've added several new chapters and taken away some. One of the ones that everyone has asked for is a chapter on alternatives to JSP. So a chapter on XML/XSLT or something along these lines will probably make it in. The new features like multiple sub-apps, workflow, role-based actions, etc... definitely will make it in. I'm not sure where at in the book, but for sure will be very important.

Re: Newbie question: Application Flow in Struts
Hi, I can't remember where I read this, but it was in the struts docn or code someplace. You struts config has something like: form-beans form-beanname=adminForm type=com.foo.AdminForm / /form-beans !-- == Action Mapping Definitions == -- action-mappings !-- load jsp page, which does a search action (.do) which forwards back to jsp page to show results-- action path=/jsp/adminaction type=com.foo.AdminAction name=adminForm scope=request input=/jsp/adminsrch.jsp validate=true forward name=success path=/jsp/adminsrch.jsp?action=results/ forward name=displayrow path=/jsp/adminview.jsp/ /action OK, so when you browse to /jsp/adminsrch.jsp Struts knows that the form bean associated with this page will be called adminForm because of the name=adminForm input=/jsp/adminsrch.jsp and the form defn form-beanname=adminForm type=com.foo.AdminForm / So struts creates a form objects and sets it up (reset). You could also create it in the preceding action option, using com.foo.AdminForm next_form = new com.foo.AdminForm(); next_form.setSomething(blah); request.setAttribute(adminForm, next_form); and then forward to /jsp/adminsrch.jsp So the answer is, the controller will instantiate the form if you go to the jsp, OR you can set it up yourself and populate it.

I have read many articles but there are still certain areas I am not comfortable with namely the backend. So let me tell what I think I know and then someone can tell me how I went wrong. When you Submit your HTTP request from the browser it gets handled by the Controller Servlet. This servlet knows to instanciate the proper formBean configured in the xml file. The proper action class's perform() method is called with the previous mentioned formBean as a parameter. This is when I get a little confused. In each of your action classes you initiate the logic to update your MODEL. So for example, myAction.perform() will instanciate/use some business objects to update the state information in the system. Since the perform() method returns and ActionForward object to the controller which I assume the controller will use to show a certain page which is based on a formBean. When should I update/instanciate/set that formBean so that the page that uses it will show the correct info? Should that be taken care of by the MODEL, either an EJB or just a regular bean, or in the Action class itself? thanks, matt lobur __ Do You Yahoo!? Send FREE Valentine eCards with Yahoo!

RE: Wizard Interface question
I dont think this approach will work if you need transactional control across the different tabs of the wizard. For example if it is a registration wizard that collects contact info and billing info on different tabs, using different forms and commiting to the database will leave you with a lot of problems. We use a single form and store it in the session rather than the request eliminating the need for the hidden variables as proposed by somebody else.

Changing ActionForms in an Action
Can an Action class perform() forward a different ActionForm to the forwarded jsp than the one it receives? Lets say I have a customerSelectList.jsp where the user selects a customer to edit and a CustomerSelectActionForm is passed to an Action. The Action retrieves the customer recond from a Model . The Action forwards to a cusomerEditForm.jsp which needs to read from a CustomerEditActionForm. Can the Action populate and forward a CustomerEditActionForm? (Yes I know the Action can stuff anything into the session or request but this is kind of a non-standard way for a jsp to access its form isn't it?). I have accomplished this in the past by having Action A forward to an Action B which is setup in struts-config to received the new form class. But that is not the best way is it? -- -- - Rick Holland OO/Distributed Systems Consultant - ObjectAge Inc. - [EMAIL PROTECTED] Logic is a wreath of pretty flowers, that smell bad -- -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Design question about ActionForm's validate method
Hi, I've stumbled across a subtle problem/design question that I don't see mentioned in the documentation. The ActionForm's validate method can be configured to verify form data from a page and generate error messages which may then be displayed on the page for the user to see. This works fine when the user has accessed the page by specifying a JSP file in the URL. When the user accesses the page by calling the Action directly though, the validate method is called before the user ever sees the page, much less inputs valid data to the form. This leads to an unfortunate display of unwarranted error messages. It would be nice if the documentation would provide a rule such as: If one plans on the user calling the Action directly in the URL then one should not use the automatic validation provided by ActionForm. Further, as having two different procedures to generate a page can lead to subtle errors, one should decide whether a page will be accessed as a JSP or as an Action and design for the one scenario. The simplest (and safest) design rule will be to access all pages through either one mechanism or the other. Comments? Sid Stuart

RE: Thread Safety Question (was Formatting Dates, Integers...)
Any use of java.text.DateFormat (or its subclasses) format method is thread unsafe (quite to my surprise). The problem comes from DateFormat holding an instance of a Calendar to help it break the java.util.Date into pieces. When a second thread calls format() while another thread is still in format(), it naturally starts poking the new month/day/etc into the [same!] calendar, overwriting what the first thread put there [and is still using]. It goes downhill from there. I got anything from garbled/mixed dates to NullPointerExceptions, depending on when and where the two threads were.

RE: Wizard Interface question
I never said that the approach you outlined will not work. What I said was it will probably not work if you need transactional control. Let me clarify. Consider the case of a wizard interface where you have contact info on one form (or tab if you will) and billing info on another tab. Now storing just the contact info in the db when the first form is submitted will leave your database in an inconsistent state if the user does not complete the second form and cancels out of the registration. Storing the information in the session will allow you to have all the required data even if the UI designers decide to move fields around in the tabs. All of the data can be written to the database on the final submit. If you mean a temporary database that holds the data from each form and then you update all of your required data at one time on the final submit then obviously your approach will work also. In that case your temp db (I am assuming this is maintained by the webAppWriter) is just replacing the session.

Direct the user to an action that isn't the action associated with the page in question, even if all that action does is forward to the JSP page. Generally the action's associated with a JSP page get called from that JSP page. ActionA forwards to B.JSP, B.JSP submits to ActionB and so on...

Re: Design question about ActionForm's validate method
I made this same 'mistake'. Actions MUST only be called when a form is submitted. Never to generate the JSP. Thats why they are called actions. Or two put it another way, you do need several URL's a) URL to JSP on a GET b) URL to action the POST The easiert way to do it is to have all forwards going directly to the JSP, and all actions in the pages going to .do. At first it seems rubish, but then you hopefully buy into the model view controller idea. i.e NO business logic in the page and it all starts to make perfect sence. But you really do have to buy into it otherwise you are fighting urge to ditch it all and go back to brilliant servlets, nice and easy, total power etc etc. Jonathan Message History From: Sid Stuart [EMAIL PROTECTED] on 05/02/2002 09:24 PST Please respond to Struts Users Mailing List [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] cc: Subject: Design question about ActionForm's validate method Hi, I've stumbled across a subtle problem/design question that I don't see mentioned in the documentation. The ActionForm's validate method can be configured to verify form data from a page and generate error messages which may then be displayed on the page for the user to see. This works fine when the user has accessed the page by specifying a JSP file in the URL. When the user accesses the page by calling the Action directly though, the validate method is called before the user ever sees the page, much less inputs valid data to the form. This leads to an unfortunate display of unwarranted error messages. It would be nice if the documentation would provide a rule such as: If one plans on the user calling the Action directly in the URL then one should not use the automatic validation provided by ActionForm. Further, as having two different procedures to generate a page can lead to subtle errors, one should decide whether a page will be accessed as a JSP or as an Action and design for the one scenario. The simplest (and safest) design rule will be to access all pages through either one mechanism or the other. Comments?

Re: J2EE BluePrints and Struts
Looks good. I like the command to iteration set up. Would a page object help? I realize that this would sort of be an iterator of iterators. Also, does making the contstuctor public make sense? Ususally the command acts as the factory for the iterator. An alternative is the builder pattern: The PageDirector calls addElement to the PageIteratorBuilder. When complete, call getIterator, which detaches the Iterator and returns it. It really depends on whether you want the Iterator to be updatable or not. You may want to have a non updatable one, and then an updatable one that extends it.

RE: Design question about ActionForm's validate method
I'm fairly new to struts (well, about 24 hours actually) and this message touches on a concept that I've having trouble grasping. Are you saying that your site should never allow the user to navigate to a URL that maps to an Action unless you are submitting a form? This is my example and although it's actually working in practice it doesn't really feel right to me and doesn't conform to above rule. I hope I've included enough detail and would appreciate any clues on good design. 1. User goes to the home page and clicks on a Find a client link. 2. This link points to /find/client.do which is defined as an ActionMapping as follows: action path=/find/client type=mysite.actions.FindClientAction name=clientFindForm scope=request input=/pages/findclient.jsp forward name=newsearch path=/pages/findClient.jsp/ /action 3. The code in FindClientAction ensures that the user is authenticated and then populates some request scoped attributes that enabled /pages/findClient.jsp to function correctly. /pagesfindClient.jsp displays a form to allow the user to enter search criteria. 4. The submit action for the form in /pages/findClient.jsp is /find/getresults which is defined as an ActionMapping as follows: action path=/find/clientresults type=mysite.actions.FindClientResultsAction name=clientFindForm scope=request input=/pages/findclient.jsp forward name=success path=/pages/findClientResults.jsp/ /action 5. The code in FindClientResultsAction examines the contents of the clientFindForm and contstructs a SQL statement to retrieve the correct data. 6. /pages/findClientResults.jsp renders the results from the database.

RE: Wizard Interface question
Taylor, Just to clarify. Putting the ActionForm in the session is simpler, but it doesn't scale as well because your session grows. It also is one more thing to worry about if you have multiple application servers and you need to support failover. So, while I agree that session beans are an option, I think in general you should avoid them where you can. regards, Stephen Owens Corner Software -Original Message- From: Taylor Cowan [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 05, 2002 12:33 PM To: Struts Users Mailing List Subject: RE: Wizard Interface question All that is not necessary.

RE: Thread Safety Question (was Formatting Dates, Integers...)
Very interesting, thank you Jeff. I am using an instance of the date format class as a private member variable in one of my buisiness objects. Each client request has one of these business objects created and placed into the session for use, as mentioned previously I too use a new getter method to provide formated dates to my jsp's. I believe this use is thread safe in that I am not creating any new threads in my app. Some developers have mentioned that the DateFormat objects are heavy weight(too heavy for each client session?). Should the date format object only have local scope in a method or be a globaly syncronized object for all to use? -Original Message- From: Jeff Martin [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 05, 2002 12:26 PM To: Struts Users Mailing List Subject: RE: Thread Safety Question (was Formatting Dates, Integers...) Any use of java.text.DateFormat (or its subclasses) format method is thread unsafe (quite to my surprise). The problem comes from DateFormat holding an instance of a Calendar to help it break the java.util.Date into pieces. When a second thread calls format() while another thread is still in format(), it naturally starts poking the new month/day/etc into the [same!] calendar, overwriting what the first thread put there [and is still using].

you have mis-spelled the error key - in ApplicationResource.properties
you have 'errors', but in the form only 'error'.
Btw. I suggest you put the error message inside li/li, so that
1) you have correct html
2) if there were more errors, the would have their own lines in the
list

RE: Wizard Interface question
Stephen, Session persistence across app servers would be an issue anyways if you put anything in the session would it not? So are you suggesting that if a project might migrate from single app server to multiple, then nothing should be in session scope? If atleast some objects are stored in session, then the solution that allows all app servers to access the same session should take care of everything. We haven't used multiple app servers and we are in the early stages of development on our project so I would really appreciate any feedback -Original Message- From: Stephen Owens [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 05, 2002 12:02 PM To: Struts Users Mailing List Subject: RE: Wizard Interface question Taylor, Just to clarify. Putting the ActionForm in the session is simpler, but it doesn't scale as well because your session grows. It also is one more thing to worry about if you have multiple application servers and you need to support failover. So, while I agree that session beans are an option, I think in general you should avoid them where you can. regards, Stephen Owens Corner Software -Original Message- From: Taylor Cowan [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 05, 2002 12:33 PM To: Struts Users Mailing List Subject: RE: Wizard Interface question All that is not necessary. You can have the ActionForm bean placed in session scope, and allow different JSP pages to fill out the properties. This is configured in the struts config file. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Change your validate to

then you have to provide message for the key error.id.required.
check the content of the file you specified as application parameter
of the ActionServlet.
eg. if you have
servlet
servlet-nameaction/servlet-name
servlet-classorg.apache.struts.action.ActionServlet/servlet-class
init-param
param-nameapplication/param-name
param-valuemy.Msg/param-value
then the properties file should be one of
WEB-INF/classes/my/Msg.properties,
WEB-INF/classes/my/Msg_xx.properties or
WEB-INF/classes/my/Msg_xx_YY.properties
where xx_YY is the current locale
the appropriate properties file should contain
error.id.required=You must supply a valid id.
or something like this.
Does it help?
# Could you send me part of your code?
it looks the same... :)

bean passing
I'm new to Struts, but have read most of the doc and examples. One basic thing that I can't quite put a finger on: how do you pass all these beans around that are consumed by the jsp's? For example, say you have a bean containing user's search results. Your display page only shows 10 at a time, and uses next and previous buttons. So, you have to persist the results from page to page. Obviously, you could explicitly add the bean to the session in the action.perform(), then reference the bean with tags using session scope. This is essentially the same way you'd do it even if you weren't using Struts. So, is there a mechanism in Struts that I should be using instead? Either it is simpler than I thought, or I am missing something obvious. Thanks, Mike -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Wizard Interface question
Well there's two issues there. The first is scalability, obviously keeping your session small helps you scale, so it's a good thing for that reason. The second is session persistence. I guess my position on it is that anything you have to persist complicates the design and slows the application down. So, even if the application server can completely transparently handle the session persistence for your actionForm you still incur a speed penalty for having it there. And, in general it forces you to think about the persistence characteristics of your actionForms, which is an issue you don't have if they're not in the session. So, on balance, unless there's a good reason to put something in the session I don't. I'm curious to hear any other perspectives on this issue as well. regards, Stephen Owens Corner Software -Original Message- From: Jakkampudi, ChandraseKhar [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 05, 2002 1:14 PM To: 'Struts Users Mailing List' Subject: RE: Wizard Interface question Stephen, Session persistence across app servers would be an issue anyways if you put anything in the session would it not?
