Re: Struts creates its own session object?
Hi, Thanks for the good explanation. Bye, Viki.

Both web applications have to use the same session. This is not possible, either with or without Struts. The servlet specification requires that the sessions for each web application be independent of each other. When you think about this a little, it is easy to understand the reasons for this restriction. The most important one is that the classes visible to each application are different, because each app loads its own WEB-INF/classes and WEB-INF/lib directories. Therefore, even if the session object were shared, a session attribute stored by webapp A might not be usable by webapp B, simply because webapp B cannot see the class for that object since it exists only in webapp A. You will need to use a strategy other than sharing sessions to share information between these two apps. Craig
validating a single textbox for two mask values
Hi,
I have a text box in which I can either enter a E-mail address or the Phone
number.
I want to use Struts-Validator for validating the format of both the email
and phone number.
How can I specify the values of both the masks for the same text box.
In the snippet given below, contactID is used to refer the email address.
Is the following correct ?
form name=myForm
field property=addContactID
depends=mask
arg0 key=prompt.contactID/
arg1 key=error.invalid.contactID/
var
var-namemask/var-name
var-value(${contactID})|(${phoneNumber})/var-value
/var
/field
/form

Struts vs JSF decision
Hello Friends, I've been working with Struts for some months now and I really like the framework and I especially like the people that participate in the mailing lists. Today I spoke with a project manager from IBM (consulting team) regarding consulting services for developing our web J2EE applications with Websphere Application Server. The specialist said he doesn't have development experience with Struts, but he strongly recommended using JSF. He said that JSF is J2EE standard and is more comfortable and flexible to work with. I don't have experience with JSF and I really need to get your opinion on this: 1. Do JSF and struts complete each or replace each other? 2. For new applications (that are written from scratch) - is it wise to use Struts or maybe move to JSF? Thanks Rivka

Struts and JSF are entirely different.JavaServer Faces technology simplifies building user interfaces for JavaServer applications,where as Struts Action is the original request-based framework. 2. For new applications (that are written from scratch) - is it wise to use Struts or maybe move to JSF? As I said JSF is different from Struts. If u want to use JSF use Struts Shale.Bcoz The two frameworks are the *Struts Action Framework* and the *Struts Shale Framework *different.. *Struts Action *is the original request-based framework. *Struts Shale *.is a component-based framework based on JavaServer Faces.

Re: Validation Security Hole?
I supposed I should reply to this on the dev list but since this thread is so long now I figured I'd add a bit more on the topic here. I see Paul/Frank what the concern is, but I think the 'problem' needs to be clarified a bit more. The problem, in my opinion, really only occurs when someone is trying to go to an action through a URL and they intentionally type in the canceled parameter which bypasses the validation procedure. On an action where you do truly want to support a cancelled operation, I believe Struts is handling things just fine. Am I wrong here Paul? In other words, you definitely would want validation skipped on actions where you are going to provide a cancel button. That's the whole point of cancelling - to typically leave the form without having completed it. You also would still want the execute method to process so you could handle the 'isCancelled' and do any cleanup or other things. I think on forms where you provide a Cancel everything works fine. It's the fact that you can spoof a canceled to other actions by typing in the URL that causes the potential problem. The solution I would like to see is if the canceled param is passed to the Action, it tries to look for a canceled method in the Action. I know this makes the Action like a DispatchAction but in this regard I don't think the non-Dispatch folks would disapprove too much. In other words, execute is never performed (not is a dispatch method performed) only the 'cancelled' method is looked for. Validation is skipped as usual for this cancelled method. This is better than having to use the current isCancelled since you are never in the your Action's execute or Action dispatch method. Another option might be to force an include in the action mapping of 'canCancel=true' for Actions that are cancelable. That might be more difficult to figure out how to handle though as far as the life-cycle goes. I haven't thought that one through. What do you guys think about just making sure a cancelled' method is looked for when canceling? The problem will be that this won't be backward compatible now that I think about it. Blah oh well. I tried:) The description by Laurie below is On 1/22/06, Laurie Harper [EMAIL PROTECTED] wrote: [Moved to a top-level thread, as this doesn't have anything to do with (either of) the thread(s) it was nested in! :-)] I think this thread deserves discussion on the dev list, but before I move it over I thought I'd post a summary to make sure I've captured all the arguments. I've also added preliminary thoughts in how to resolve the issue at the end of this post, though that discussion definitely ought to proceed on the dev list I guess. I'll re-post this message to the dev list later today if I haven't missed anything important below: * Issue: addition of a 'org.apache.struts.action.CANCEL' parameter to any request will cause validation to be skipped, but the rest of the request processing / action invocation cycle to proceed normally * Consequence: any action which proceeds assuming that validation has completed successfully and which doesn't explicitly check isCanceled() is proceeding on a broken assumption * Questions: - why doesn't Struts call validate() on a cancelled request? If a request is canceled it usually means validations don't apply since the implication is that any user input will be thrown away. Users shouldn't be required to supply valid inputs for actions they are canceling. - why does Struts still call Action.execute() for a canceled request? Since you may still want to act on a canceled request (e.g. to clean up resources stored in the session). (Some of?) the DispactAction variants dispatch to a special method and aren't subject to the consequences listed above, but most action implementations don't. - why does Struts still populate the action form on a cancelled request? If inputs are going to be thrown away anyway, why process them by populating the action form? [Commentary: I believe this behaviour makes sense since it preserves a standard way to access the request data, should you want to, regardless of whether the action was canceled. You could argue that either way...] Here's my first thoughts on possible approaches to addressing the problem, to kick off further discussion on the dev list: - SAF1.2 and before: ? document, don't fix? add config req'm'ts on action mapping? Refer to discussion on user list for various options. - SAF1.3+: make cancel processing a command which you have to include in your request processing chain, and perhaps disclude it by default? [I'm not familiar enough with how you deploy chains on a per-action basis to know if this is the right way to do it...] - WW2/SAF2: implement cancel processing as an interceptor and either disclude it from default stack or require an action to implement an interface declaring that cancel processing should

I even just tried to cancel my subscription to that list but never received the confirm letter. When I email that address directly the messages do seem to get there, so I'm having trouble figuring out what the problem is. I'm pretty sure it's on my hosting provider's end but it's difficult for me to confirm this. Is there anyway I can see if messages are bouncing to the listserv or what might be going on?

Re: Struts vs JSF decision
On Mon, January 23, 2006 6:08 am, Rivka Shisman said: The specialist said he doesn't have development experience with Struts, but he strongly recommended using JSF. He said that JSF is J2EE standard and is more comfortable and flexible to work with. This is exactly the kind of opinion I would *not* trust... here's someone who admits to not having much experience with Struts and yet he can say that JSF is to be highly recommended? That's like me saying well, I like beef more than pork, I eat beef all the time, but I've only had pork once or twice. Doesn't make much sense, does it? :) Plus, IMO, you shouldn't put as much weight in anynoes' opinion that says you should use *anything* simply because it is a standard. That's a reason to give something due consideration, and maybe that's the final weight that tips the scales in its favor, but especially if it's the *first* reason he states, there is a priority issue there IMO. I don't have experience with JSF and I really need to get your opinion on this: And I have only some experience myself, so you shouldn't put a tremendous amount of weight in my opinion either :) 1.Do JSF and struts complete each or replace each other? Depends on who you ask... some are very hard-lined and believe JSF is *the* future of Java web development. Others are more reasonable and will tell you that you should decide which fits your needs better after some diligent research and perhaps trials (and there are those that say JSF is crap and should never be used, which is pretty ridiculous too). My advice echoes those who say you should decide for yourself. JSF seems to suit some people and some projects very well, others feel Struts is much better for them. Make up your own mind :) 2.For new applications (that are written from scratch) - is it wise to use Struts or maybe move to JSF? Again, depends on your needs. Struts isn't going anywhere for a long time. Some have taken to calling it old technology or saying it's past its prime or such things. I find those to be ridiculous claims. Struts (in some form) and JSF will likely coexist for a long time. In fact, that might always be the case... Whether JSF is a standard or not, there is *no* guarantee that anyone will be using it five years from now. There is *no* guarantee that it will dominate the landscape. It still has to prove itself to a great many people. Struts OTOH has already done his, and for all its supposed flaws, people continue to use it with great success. JSF may well be the future, but it's not a guarantee simply because it's a standard or because it's got the marketing behind it. I would hope there is always a choice frankly. Otherwise, we might as well all jump to .NET :) JSF has its pluses and minuses, so does Struts. And so does every other framework out there that you could alternatively choose. Decide which to use on the merits of your situation, not what some consultant or marketing drone says.

Re: struts and JSTL
The problem is that you're putting the 'amount' field into a hidden
field and then trying to use that hidden field as a value, but your
amt bean will actually contain the value of the form field: input
type='hidden' value='123.00'/
Try this instead. First, in your action save this amount value to the
request scope:
request.setAttribute(amount, yourAmountVar);
Then put in your JSP, assuming a JSP 2.0 container:
td
fmt:formatNumber value=${amount} type=currency/
/td

Re: [JSF] Client state
From: Michael Jouravlev [EMAIL PROTECTED] Can JSF store component state completely on client, that is, using Javascript objects? I could not find anything besides _viewstate-like juggling between client and server. JSF has an option to store the state of the page as a hidden field in the client. It's serialized objects that represent the component tree. Client state is more for handling the browser back/ dirty page more than making state available for javascript. I think it would be nice if an application could try to save viewstate on client, and if Javascript were turned off, the viewstate would be submitted to server and stored there in the session. It's a global on or off switch now. It would be nice if the client state was something usable by javascript. Shale is working on an idea of decorating renders so that you can modify the default content without having to know allot about the component. For example, you could intercept the generated html and write javascript to write dhtml. Or, add some ajax features to a component. I was talking with David Geary and he would like to see tiles hook into AJAX so that you could control the content of a DIV tag like you might a iframe. I guess this would be like creating a view root as a leaf node in the component tree representing the page. This is still kind of blue-sky stuff.

No problem :) Yes, that's correct... with every document loaded into the browser, anything that existed before is wiped out. I'm not aware of any way around that (and it sure sounds like a security problem if there was). A hidden frame is the typical solution in such cases... Of course, now you can do it with AJAX... you load one page in the beginning that contains your AJAX code and a single div... every request you make to the server goes through an XMLHttpRequest object, and the results are stuck into that div... this can be a whole page, so in a sense your creating a browser inside a browser :) Michael.

RE: A couple of simple questions
Yes, you can't use a .do action for the welcome pages. This is because web.xml is lower down than the struts stuff. The web.xml also configures the strust controller servlet to intercept anything ending with .do. If you think about this you can understand how, at the web.xml leve, there's no meaning to the .do yet. The best practice is to put an index page that contains only a redirect to your first struts action ( your entry point, logon.do or something like that ) --- On Mon 01/23, David Thielen [EMAIL PROTECTED] wrote: From: David Thielen [mailto: [EMAIL PROTECTED] To: user@struts.apache.org Date: Mon, 23 Jan 2006 11:39:39 -0700 Subject: RE: A couple of simple questions Asking again - thanks - dave-Original Message-Hi;1) I want my default page to be index.do so I set the following in web.xml: welcome-file-list welcome-fileindex.do/welcome-file/welcome-file-listBut instead I get a directory of files in my root when I go to the servlet.I can do this which works: welcome-file-list welcome-fileindex.txt/welcome-file/welcome-file-listIt appears it wants a file.

html-el:select and tag files
Hello,
This may be more of a jsp 2.0 question than a html-el tag
library question, but here goes.
I have a jsp page that has a list of dates that need to be
entered. I have a custom tag file that displays a date selector using
three html-el: selects (year/month/day.) It takes as attributes the
form property name and the index. The dyna form bean, for legacy
reasons, does not contain an array of date objects, but rather three
arrays of integers, one for date, one for month, and one for year. So
the form bean looks like:
form-property name=prop_date type=java.lang.Integer[]/
form-property name=prop_month type=java.lang.Integer[]/
form-property name=prop_year type=java.lang.Integer[]/
and the tag library looks like (without its header):
%@ attribute name=property required=true %
%@ attribute name=indexrequired=true %
html-el:select property=${property}_date[${index}]
!-- bunch of options here --
/html-el:select
html-el:select property=${property}_month[${index}]
!-- bunch of options here --
/html-el:select
html-el:select property=${property}_year[${index}]
!-- bunch of options here --
/html-el:select
The problem I face is that let's say the jsp using the tag does this:
c:forEach var=foo items=${someFoos} varStatus=status
myTagLib:dateSelect property=prop index=${status.index}/
/c:forEach
Then I get:
javax.servlet.jsp.JspException: Invalid indexed property
'prop_date[${status'
presumadely from the html-el:select. I'm assuming that status.index
isn't getting evaluated when invoking the dateSelect tag, and so when
${property}_month[${index}] is evaluated by the html-el:select tag, it
gets 'prop_date[${status.index}]' and doesn't recursively evaluate to
find the value of status.index. Any suggestions on the correct way to
deal with this?
Thanks,
-Clint

What do you mean by do it the other way around ?

I'm not aware of any way around that (and it sure sounds like a security problem if there was). A hidden frame is the typical solution in such cases... So, there are ways besides Ajax? This is good to hear. Yep, but they tend to be flowned upon by most. For whatever reason, frames have gotten a really bad rap over the years. The three options I am aware of are frames, hidden fields and URL rewriting, and AJAX. Of course, now you can do it with AJAX... you load one page in the beginning that contains your AJAX code and a single div... every request you make to the server goes through an XMLHttpRequest object, and the results are stuck into that div... this can be a whole page, so in a sense your creating a browser inside a browser :) Yeah, I know, I do that myself. I was curious about independent pages. This hidden frame thing... Can it work while actual page content is changed *and* page address is updated in the address line? Frames are in essence separate browser instances crammed together... well, not *quite*, I suppose it's more like multiple tabs in a browser where the content of each tab is shown together. So, if you change the content of one, even if its redirecting to another URL, the content of the other is completely unaffected. With frames, the URL you see in the address bar rarely corresponds to anything useful... That's one of the reasons people started to dislike frames... it tended to make bookmarking more difficult, i.e., if you have two frames, they each build up their own history, so if you try and bookmark a page, you may have content in one frame that doesn't correspond to what's in the other (think of a menu frame that changes according to what page is dislpayed in the other frame)... usually what you bookmark was the address of only a single frame anyway, and that doesn't really get you what you want because then the content of the other is underfined (and more than likely when you try and go back to the bookmark, it's not a frameset any more because that's likely not what got bookmarked anyway). To get around these problems requires you to write Javascript that can properly be sure all frames involved are updated. For instance, if you click a link that brings you to page A in frame A, and you need page A1 in frame A1 to be present, you would need to write code in page A that, onLoad, loaded page A1 into frame A1 as well. It allows you to do some really cool things, but it's definitely more work and more error-prone. Michael.

The problem is that you're putting the 'amount' field into a hidden
field and then trying to use that hidden field as a value, but your
amt bean will actually contain the value of the form field: input
type='hidden' value='123.00'/
Try this instead. First, in your action save this amount value to the
request scope:
request.setAttribute(amount, yourAmountVar);
Then put in your JSP, assuming a JSP 2.0 container:
td
fmt:formatNumber value=${amount} type=currency/
/td

HomeVC.init(), requestURI=/cpt/home.jsf HomeVC.prerender(), requestURI=/cpt/home.jsf BaseViewController - /cpt/home.jsf is a secure url and not logged in, redirecting to login: /login/login.jsf HomeVC.destroy(), requestURI=/cpt/home.jsf HomeVC.init(), requestURI=/cpt/home.jsf HomeVC.prerender(), requestURI=/cpt/home.jsf BaseViewController - /cpt/home.jsf is a secure url and not logged in, redirecting to login: /login/login.jsf HomeVC.destroy(), requestURI=/cpt/home.jsf The init,prerender,destroy are not called for LoginVC - Why not? The wierd part is that the browser behavior is working as expected - up to a point. Once I hit the login button, the user is logged in, but the navigation rule in faces-config, isn't sending the browser to the home url. Another interesting thing... after the login form is displayed, and I Manually enter the login URL - the init,prerender, and destroy methods are not called by ANY ViewController. PS... I do have no-cache meta tags in the jsps, and I also set the headers in my baseViewControler.prerender method - so at least the browser shouldn't be caching anything.

The problem is that you're putting the 'amount' field into a hidden
field and then trying to use that hidden field as a value, but your
amt bean will actually contain the value of the form field: input
type='hidden' value='123.00'/
Try this instead. First, in your action save this amount value to the
request scope:
request.setAttribute(amount, yourAmountVar);
Then put in your JSP, assuming a JSP 2.0 container:
td
fmt:formatNumber value=${amount} type=currency/
/td

RE: [Struts EL JSTL]
To answer this a little differently than Laurie did, the Struts-EL tag
library is a collection of tags that all inherit the behavior of the
Struts tags they replace, except the tag attribute values are passed
through the JSTL expression evaluation engine implemented by the Jakarta
standard taglib implementation.
The Struts-EL tag library is only useful in a JSP 1.2 container (or in a
JSP 2.0 container if not specifying the Servlet 2.4 spec). If you have
a JSP 2.0 container, and you specify the Servlet 2.4 spec, then EL
evaluation is done natively in the container, so you don't need a
special tag library to implement it (and it would probably cause
unexpected problems if you used it).
If you just used the Struts tag library, then attribute values in the
Struts tags like ${stuff} would just produce the value ${stuff}. If
you were instead to use Struts-EL, then it would produce a value based
on the value of the stuff scoped attribute.
In fact, the Java classes in the Struts-EL library all inherit from the
corresponding Java classes from the Struts tag library, it's just their
setters/getters that cause the values to be passed through the EL
engine.

Re: returning a non-html file as response
Craig McClanahan wrote: Let's try to be a bit more helpful here :-). No object :) The only thing Struts itself might do is try to set the no-cache headers if you have them configured. It does not, by itself, ever write to the response stream or response print writer. That's the responsibility of whatever your action forwards to. Right, that's what I thought, thanks for confirming it! Calling flush() doesn't necessarily cause the *entire* response to be sent, because you might still be creating more output. But it *does* cause the HTTP headers, and any output content you've written to be transmitted. From the perspective of the servlet API, this response has now been committed so you cannot later decide to do a redirect or forward. In general, the only use case I can think of for calling flush() yourself is if you have something like a Request In Progress - Please Wait at the beginning of your page, and you want that to show to the user while a time-consuming process is performed to create the remainder of the content. Interesting... I would have thought just the opposite, but this makes sense. I suppose one could imagine a problem with a filter that does some post-processing occurring if you flush() yourself. So, leave flushing to the next guy, contrary to what everyday etiquette would seem to indicate ;) LOL Struts doesn't but the servlet container will, once your processing has finished. This is a guarantee of the servlet API I would assume? It seems like it logically would be, but I wasn't sure.

Re: returning a non-html file as response
A compression filter does exactly that, that's the reason it occurred to me :) I remember facing *precisely* that problem a few months back with the JWP sample app. I know I solved it, but I guess I had forgotten the root cause :) Frank Craig McClanahan wrote: On 1/23/06, Frank W.

jstl tutorial/reference?
Hi, I'm developing a struts based application and would like to use jstl tags instead of custom tags specified with struts tag lib. Is there a good JSTL tutorial/reference available which gives good example usage also of how to use the jstl tags. Thanks Deep - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
