Re: Session-Problem
Hello,
I have the same problem some days ago. I found two solutions: using
https(SSL) in the web server (if SSL really fits to your application
security requirements), since SSL web pages are not cached, or telling
the browser to don't cache the JSP page, so when the user clicks the
back button the browser will have to send a request.
response.setHeader("Cache-Control","no-cache"); //Forces
caches to obtain a new copy of the page from the origin server
response.setHeader("Cache-Control","no-store"); //Directs
caches not to store the page under any circumstance
response.setDateHeader("Expires", 0); //Causes the proxy
cache to see the page as "stale"
response.setHeader("Pragma","no-cache"); //HTTP 1.0 backward
compatibility

Re: DynaActionForm and the 'pull' model
I believe the point was nothing like this at all, Dave. Don't know why you thought it was. Seems like you just thought this stuff up separate to me. However, certainly I don't think that the issue whether or not you are writing a CMS is relevant to the issues discussed. I also have no idea why you went off on the XML stuff. This is simply an issue of where work on the model should be. Your discussion, so far as I can tell, is about something entirely different and I have no idea where you got these issues. If these are the issues, then you must be speaking some language with Ms. Harper that I don't know.

If you know they're the same size and in the same order, (should be the case
with List,) how about iterating over one with

Can you change the design? If the items in both collections really belong
together, try to store them together so you don't have to jump through hoops
like this.

You do realize, that JSP _is_ a part of app source code, do you? And the more you put into JSP, the more this supposedly dumb JSP page will look like "real code"? If you ship without source code, you'd rather precompile the JSPs. Now, to your problem. I will try to think right while I am typing. First of all, I haven't actually used dynaforms, so no advices here. Now, you want your input to go to action form? Why? Apparently, because you want Struts to parse request data, and to perform automatic validation. OK. So you need to associate form bean with every incoming request, but you do not want to redefine form beans, hence dynaform. Struts uses getters and setters to put values into the form (at least if it is not a dynamic form), so you can use getters and setters to direct where the data goes... I am not sure how do you do this with dynabean, but with regular bean you would have your getter pulling data from your view object, and the setter storing data in the form field. Then, after validation, you would type-convert and copy values from form fields to your view object. Or... you can still pull data from your view object and display values using bean:write. But the tags themselves will have "property" pointing to the form bean. I am not sure how this will work, but if you were able to print values from view object, and submit them to the form bean, then you'd just copy them to view object, and _then_ validate them. Then, if needed, you would redisplay data again from the view object, which contains updated data (possibly incorrect, but who cares, this view object is a _copy_ of a real object anyway, right?). In this case you do not need getters in the form bean. Because there are no getters, this "pull from view object, submit to action form" might work. I have not really tried it.

To me it looks like a place where a different delivery mechanism, like XML, and subsequent transformation might be more appropriate: more service-oriented rather than page-oriented.

This is not, again, a "pull/push" issue. Pull and push are relationships between client and server. Your relationship is between the view and the model.

Re: Stateless web apps
andy wix wrote:
I am working at a place that doesn't use session state for their web apps.
The reason given is that they have 2 physical servers and 2 Oracle
Application Servers running on each of these machines for failover.
From the little I know about clustering, I thought that if everything
in the session implements Serializable then session state is
tranparently valid accross requests - even if you end up on another jvm.
Has anyone else ever heard of this restriction - I can see problems
e.g., can't use Struts tokens to defeat the usual refresh problems.
Sharing sessions between containers ('session clustering') is not a
standard feature -- i.e. the Servlet spec neither requires this
capability nor specifies how it should be impelemnted. However, most
modern contains do support session clustering, in their own proprietary
way. For example, Tomcat supports session clustering via shared disk,
JDBC datastore, etc.
I don't know what session clustering abilities Oracle Application Server
has but it can probably be configured to do this. Bear in mind that
there are performance tradeoffs to consider as well as opperational
impact -- for example, if you cluster sessions via shared disk, you now
need to make your shared disk array redundant as well.
If you can implement your application without relying on sessions at
all, your life will be simpler ;-) If you do need to implement session
clustering, consider using host affinity as an alternative. With host
affinity, the load balancer is configured to share sessions between the
servers equally, but allways route requests for a particular session to
the same server. That saves you the overhead of session clustering, at
the cost that if one of the application servers goes down all users
whose sessions were housed there will loose their session and have to
log in again on the other server.
L.
More immediately, I have a problem with a typical scenario. My normal
approach is:
I have a 'preload' action that gets an ArrayList of data from the db and
sets this in the session.
Then forward to the jsp that displays this stuff.
This page has something like:
This gives me an index of the link that was clicked and in the next
action I simply look this value up from the ArrayList in the session.
Does anyone know how this functionality could be achieved without using
the session?
Assuming you can rebuild the list at any time, you can use request scope
instead of session scope and rebuild the list at the start of each action.

Re: DynaActionForm and the 'pull' model
Rather than pollute the view (if one chooses to perceive it that way... I'm staying away from that debate!), why not introduce some sort of scripting engine into the mix? I'm not really sure precisely where because I don't know your project, but I say this based on your comment: "True, at development time. But it's a lot easier if you don't *have* the source code to the model or rest of the system." Think of something like Microsoft Excel... you don't have access to the source code obviously, but it exposes are rather rich object model that you can manipulate through scripting. This lets you customize the app in essence in just about any way you want without needing the source. It also is arguably better architecturally than allowing someone to alter the dialog resources of the app (not a perfect analogy I realize, but hopefully close enough to get the point across). There is the scripted Actions project specifically for Struts, there's Jelly that might be applicable, the BSF, etc. Something along those lines is almost tailor-made for the "the client needs to modify our product in some way" situation. -- Frank W.

Consider a comercial product implemented on Struts and JSPs. You build the product and ship it to customers. You don't ship the source code -- that's proprietary -- but you do ship the JSPs and you want the customers to be able to locally customize the application. This is where the pull approach provides a great deal of flexibility. There are a lot of things you might want your customers to be able to do by way of customization that are simply not possible using a push methodology. L.

I'm not really keen to 'pollute' the view objects with String-type derived properties just for the HTML presentation; the view objects are how any client (web app, web service, Swing GUI, etc) would interact with the application. This also implies having String-to-model conversion code scattered through the view objects... I don't really get what you mean in your (2). This is what I decided to try first. I threw together a prototype last night, and it seams to work well. Basically, the idea is: - extend the view API to include 'View.toMap(Map props)' and 'void View.fromMap(Map props)' on each view class - you can then do view.fromMap(form.getMap()) and view.toMap(form.getMap()) to translate between views and form beans - add a custom tag which takes a form bean and a view and loads the form's map from the view (I've implemented this so it can lookup the form bean from an enclosing tag, so you only have to pass in the view) Now, my JSPs can do something like this: ... setup view (e.g. populate from db) ... Now, the form bean associated with the enclosing form is populated from the view object. On subsequent page loads, I can skip the loadForm tag, and the form bean has the data from the previous submission. I still need to do some more testing, but this seems to be working nicely. I think the parameter handling issue is hugely debatable. I've lost count of the number of discussions I have had about it. Yeah, lots of options here :-) Alot depends on where you get your view objects from. Are they the data transfer object pattern? Roughly, yes. There's a 'service layer' that interacts with the domain model (business objects). It returns view objects which are POJOs containing the state from the business objects but not the behaviour.

Hi. Anybodoy knows how can I access the action B's ActionMapping from the Action A (a preprocessing filter that is executed before every action) ? I have to do that because I need to read the properties of many actions in the filter, to check if the user can execute those actions. I've tried the method ConfigHelper.*getActionMapping*(java.lang.String path), but it returns null because it's not implemented yet. In Struts 1.0 there was a ActionServlet.findmapping method.

Re: DynaActionForm and the 'pull' model
Dakota Jack wrote: You cannot talk about request objects and ignore the client. The requests come from the client. Sure, but I'm not talking about request objects. A request to http://host/myapp/something.jsp (with no query parameters) contains no request data, but the JSP still has to display information. What I'm taling about is how that information is retrieved from the backend. Any data coming to a JSP comes in the same way. This is not pull and this is not push. The data comes from some class existing in some scope: page, request, session, application. You are not doing anything new. You are just doing the old stuff badly, I believe. I only say that to be helpful as I can be and not to belittle you or anything like that. Your cases has the JSP more than requesting the data. Your case has the JSP in charge of getting the data. That is very different. Any data coming to a JSP must be "requested", i.e. gotten from some call from the JSP page. Your pages does more, viz. instantiates the objects, etc. which provide the data on the JSP page. Again, your idea that way is flexible is not true. You are less able to "customize" with your approach because you have all sorts of disparate code tied to each other. If you have a variable on a JSP page be a logical reference to data, then the physical source of that data becomes irrelevant. You, however, make direct references rather than logical references and tie down your code completely. JSPs access data through page/request/session scoped variables, just like yours do. With a push methodology, a JSP may assume that there will be a request scoped variable 'user' which references a bean of type UserView. It renders the page by making reference to the properties of this bean through the 'user' variable. The only difference with a pull methodology is that, somewhere in the JSP, there is a . The rest of the JSP is written exactly as it would have been using a pull methodology. There's no 'disparate code' and the references to data are no more or less direct than when using push. The coupling is the problem. Coupling leads to fragile, rigid, code which is expensive to maintain. Absolutely, which is why it's important when using pull to keep it simple and make sure data retrieval is as declarative as possible. I'm certainly not advocating that JSPs should be making JDBC calls or anything. I hope this is helpful, and realize that I am just stating my opinion. I don't think you are at all right, but certainly am willing to listen to what you have to say. As I said in my previous post, you need to understand the design constraints. No approach solves every solution, no design rule is inviolate. I'm using a pull model to solve a very specific requirement: that the data displayed on a JSP page should be able to be changed /from the JSP page/, without access to the application source code. I can see why it looks, at first glance, like I'm doing something badly wrong but, in the light of that requirement, I'm not aware of another approach that's workable. Feel free to suggest alternatives if you have them :-) L. On 5/22/05, Laurie Harper <[EMAIL PROTECTED]> wrote: You're bluring the distinction between client-side behaviour and server-side behaviour a little there. Ignore the client side for the moment; I'm talking only about how the application works on the server. The issue is about how the JSP gets access to the data it needs to display. Normally, as you say, there would be an action or some other server-side component which executes before the JSP and places data into some scope which the JSP then retrieves. That's what I'm refering to as a 'push' model, in that there is some component pushing data out to the JSP. In my case, I want the JSP to get access to the data by explicitly requesting it -- i.e. 'pulling in' the data it needs. As I noted in my other reply to you, this could be seen as breaking the MVC paradigm by putting application logic in the JSP. There's some truth in that. The reason I do it is quite simple. By having the JSPs aquire the data they need in this way, it is much easier to customize the application after it is delivered. Page flow can be changed, additional information can be shown on an existing page, and so, all without modifying Java code. That means I can deliver a highly customizable product. It's a trade-off: I bend MVC encapsulation, but gain a significant benefit. So, 'pull', in the context of this discussion, just refers to how the JSP gets acces to the data it needs. In my implementation, the JSPs instantiate beans which represent a view of the data they need. The beans then do the work of interacting with the backend (via a service layer). So the data access is really still in the controller part of the application, it's just being triggered by the JSPs rather than by a Struts action. In a way, you can think of it as using the JSPs to declaratively describe what data

okay, but handling sessions is nothing special for a certain framework. I
tend to place it some where in the container area itself, how to react on

Re: Re: Antwort: RE: howto redirect to login site after session expiration?
In part you are correct. You can try doing this: in web.xml 404 /pages/error.jsp This goes after and before any declarations. The 404 can be replaced with any html error code you wish (as far as I know). I'm getting an NPE error right now and the error code is 500. So you can probably put that up. I don't use it (currently) because I like to see the stack traces live instead of using log files to debug, but when I release the site I put up real error pages and use web.xml.

Hi,
okay, but this leads to a solution where I do have to ensure a manuell

that the container is maintaining a list of expired sessions (or at least
valid sessions to figure out invalid sessions), so that I can _configure_

session, means a session id stored in this list.
The problem with the NPE is a general prob that applies to all use cases
where the user leaves some input site open in the browser and tries to
submit it after the session timed out. The Struts framework finds no bean
with bean with the formname specified in in the newly

the bean but the new ActionForm isn't initialized yet (object graph) so
all access to nested properties will result in a failure.
However, checking and handling expired session is IMHO very low level

If you keep a user object in session, just check at the beginning of the Action whether it is still with you. If not, forward to a log on page. I assume that will work for you. If you don't have a user object in session, whether authorized or not, then you can put a simple String iin session saying "live" to test the session.

Re: Antwort: RE: howto redirect to login site after session expiration?
This is what I use...
-- main body here --
Now if you're talking about the person filled out the form (or
whatever) and then let the session expire.. The first thing I would
check in the Validate Method would be to see if the session attribute
I put there when logging in was actually there. As for the NPE, I
debug based on trial and error sometimes and since I don't have your
full logic flow I can't give you a for certain answer, just
suggestions.
if ( request.getAttribute(" ") == null) //not sure what getAttribute
returns if nothing is there.
{
mapping.findForward("expired");
}
Hope this helps,
Andrew

RE: Populating growing List
The solution, we later adopted was have a class extending ArrayList, some
thing like this..
class MyList extends ArrayList{
public Object set(int index, Object element)
{
if(index > size())
{
add(new Object()); // Add objects of appropriate type
to avoid ClassCast exception
}
return super.set(index, element);
}
public Object get(int index)
{
if(index > size())
{
add(new Object()); // Add objects of appropriate type
to avoid ClassCast exception
}
return super.get(index);
}
}
obviously this is simplified form of that class.

The reason this isn't working lies in how Commons BeanUtils works. What you
read in the wiki works for setting the properties of nested "indexed beans"-
not straight forward indexed properties. In this circumstance it will just
call the indexed setter so for it to work you need your lazy code there,
rather than the indexed getter.

RE: Populating growing List
On the surface it looks like the code is wrong. Index 0 represents a
size of 1 (zero-based array). Once you account for that, your array
should grow as you desire.

Dealing with many forms
Hi, I am writing my first Struts application, and have some problems with it. Some part of my app, gets data from database, fills appropriate form, displays it and, if user changed the form, writes data back to database. Another functionality is: get whole webpage (including form)from database, fill it with data and if user changes it, write changed data back to database. It was done with Jsp and JavaScript. Writing ActionForm for each form would be senseless because part of functionality of the app is that any user can submit new forms. And now the problem: Some devices do not deal with JavaScript well (some palmtops, cellphones etc). And my app must run properly on them. So, is there any way to do the task above without JavaScript? -- Pozdrawiam, Janek Ziniewicz gg:902858 irc.freenode.net: #gore, #dub - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If your form bean is being used in multiple page, you can put the form in

Stateless web apps
Hi, I am working at a place that doesn't use session state for their web apps. The reason given is that they have 2 physical servers and 2 Oracle Application Servers running on each of these machines for failover. From the little I know about clustering, I thought that if everything in the session implements Serializable then session state is tranparently valid accross requests - even if you end up on another jvm. Has anyone else ever heard of this restriction - I can see problems e.g., can't use Struts tokens to defeat the usual refresh problems. More immediately, I have a problem with a typical scenario. My normal approach is: I have a 'preload' action that gets an ArrayList of data from the db and sets this in the session. Then forward to the jsp that displays this stuff. This page has something like: This gives me an index of the link that was clicked and in the next action I simply look this value up from the ArrayList in the session. Does anyone know how this functionality could be achieved without using the session? Thanks, Andy _ It's fast, it's easy and it's free.

Antwort: RE: howto redirect to login site after session expiration?
Hi, unfortunately this is not an good option because the application (exactly some of the actions) serve authorized and unauthorized users the same. Afaik if a user sends his first request a session will be created for him (default behaviour). Additionally we invalidate a session when a user authorizes and store his credentials etc. in a newly created one. I was quite sure that handling of an expired session could be done declaratively. I feel some pain doing such a basic thing in proprietary code. I rather think that this is something that should be handled by the container. I just want to say, if your session expired, go to page xyz. BTW: how can I determine via the API if a session expired? Is it possible at all?

RE: sTRUTS 1.3 - chain flow / complex app
Hello all, >It's interesting to have some more complex use cases to test the >chain model against... I would offer my app as 'guinea pig' for complex cases :-) Currently it's a small app that manage my own 'expenses' (I have a mysql as backend and jboss 3.2.5/tomcat 5.5 as app server)to see What do I spend an where (yeah, I m not that good with money :-) I am updating my db almost automatically via quartz job, using struts as user interface for manual insert of expenses and job scheduling.. I m using castor/hibernate as ORM frameworks, and spring & struts I manage to port it from struts 1.1 to struts 1.3, and I was looking into strutsws cos I want to have J2ME clients that communicates using ksoap. I am looking forward to add more complexity for 'testing' the chain.. If you have anything to suggest me, go ahead :-) .. Does Shale use chain? Could you integrate chain in Shale?

Re: JSP Buffer Size
Hi, if you use Java Servlet specification version 2.3 (at least) you can use a Filter. make your filter intercept the jsp and in that filter you can change the buffer. for a more information about Filter take a look at this: http://java.sun.com/products/servlet/Filters.html Catalin On 5/22/05, tarek.nabil <[EMAIL PROTECTED]> wrote: > Hi everyone, > > Is there some way that I can set the buffer size for all JSPs to some > value other than the default 8kb without having to do it in every JSP? > > Thanks > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: sTRUTS 1.3 - chain flow / solved
Hello, Looks like I found a way to make it work! :-) I have submitted the code to Frank..surely he'll find way to optimize it.. For now, I had to extend few commands (SelectAction, ValidateActionForm, PopulateActionForm & SelectForward) and I had to rewrite struts chain-config.xml to use my own commands... Thanx to all of you who gave me precious hints! Regards Marco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: JSP Buffer Size
If you are using Servlet 2.4, then you can use the to specifiy a page that is included at the beginning of every jsp page. You can put page directives there. http://java.sun.com/webservices/docs/1.3/tutorial/doc/JSPIntro13.html eg /template/prelude.jspf tarek.nabil wrote: Thanks Martin. But this is exactly what I'm trying to avoid. If I use the page directive, then I would need to do that in EVERY page. My question is, is there a way I can do this with Struts in some central place only once? -Original Message- From: Martin Gainty [mailto:[EMAIL PROTECTED] Sent: Sunday, May 22, 2005 4:13 PM To: Struts Users Mailing List Subject: Re: JSP Buffer Size assuming you can handle the exception when buffer overflows <%@ page buffer="9kb" autoFlush="false" %> Martin- - Original Message - From: "tarek.nabil" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" Sent: Sunday, May 22, 2005 4:25 AM Subject: JSP Buffer Size Hi everyone, Is there some way that I can set the buffer size for all JSPs to some value other than the default 8kb without having to do it in every JSP?
