Access ASO outside of Tapestry (i.e. in Servlet Filter)?
Hi! I have to access an Application State Object in a Servlet filter - so I can't use tapestry's injection mechanism. What's the preferred way to access an ASO? I thought about access via Hivemind... but I can't find doco about this rather special case.

Basic HTTP Authentication in Tap 3 = Acegi + Spring ?
Hello all, My production system still runs on Tapestry 3.0.4/Hibernate/Spring. I would like to setup Basic HTTP Authentication scheme for some non-critical, but administrator-only pages (ie. usage stats etc.). For normal user pages we currently use authentication mechanism, but what I need is fast, non db authentication. My first thought is to use old-rusty HTTP Basic Authentication scheme. What is the easiest suggested way to do it in Tapestry? Can this be achieved with Acegi with Tapestry 3? How do I set up Acegi using just Spring? All of previous discussions on Acegi were in context of Tapestry 4, unfortunately (for me :) ) Any suggestions, help, guidance, links to threads I may have missed will be appreciated, Thanks in advance, Bernard - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It is registered on particular pages and does the following: 1) If user sent 'Authorization' header, decode auth details and check if they're OK. If yes go to 4.

Re: Order by which events and listeners are called
I'd suggest using pageValidate on every page EXCEPT the login page. Do the login validation in the doLogin method and set your Visit or similar object there before activating the next page. You could have a look at JumpStart for an example. http://tapestry.apache.org/ tapestry4.1/QuickStart/contributed.html Regards, Geoff On 18/07/2006, at 10:17 PM, Rui Pacheco wrote: Hi all I have a chicken and egg problem. I included a login component in my page. That component is supposed to receive the username and password from the user and process it in its form listener in order to check whether the user is valid or not. The way I see it, the user would fill the username and password, a query on the listener would check whether the user exists or not and then the page would load normally. My problem is, pageValidate, the natural place to check whether the user has permissions to load that page or not, is being called before doLogin and this makes it impossible for the user to login. The order by which events and listeners are being called is pageValidate, pageBeginRender and then doLogin. Am I wrong to assume the only way I have to validate the user is to pass the username and password into the pageValidate event and then do all the db work there?

Re: Question about PageValidate
Contained within my Border I have a navigation component that contains a number of @DirectLinks.

This is what I suggested too. If you've put your authentication listener
in AbstractWebPage then your Login page cannot extend it any more.
If you want authenticated pages and Login page share common
functionality you have to move the authentication listener down in the
class hierarchy i.e. to AbstractAuthenticatedWebPage.
This would look like this:
public class AbstractWebPage
extends BasePage
{
common functionality hoes here
}
public class AbstractAuthenticatedWebPage
extends AbstractWebPage
{
.. pageValidate authentication check listener goes here
}
public class LoginPage
extends AbstractWebPage
{
.. some login listener goes logic here - no auth check done
}
public class SomeAppPage
extends AbstractAuthenticatedWebPage
{
... application page that check whether user has logged in
}
Another approach is to create simple non-html component, lets call it
AuthenticationRequired and place it in pages which does require
authentication. This may be better than page hierarchy approach if only
some of your pages require authentication.
Such component can look like this:
public abstract class AuthenticationRequired
extends AbstractComponent
implements PageValidateListener
{
public void pageValidate(PageEvent event)
{
do some authentication check
and redirect conditionally to login page
}
protected void renderComponent(IMarkupWriter writer, IRequestCycle

{
// Nothing to render
}
}

And this is another very good idea. But if I stick with the abstract

component will force me to copy/paste it accross all the templates.

RE: external link to a tapestry page
You're on the right track by using an External link. Make sure your page implements IExternalPage. We do something similar with one page that we wanted to be bookmarkable and the URL Format is quite similar to what you're trying. You'll still have to workaround problems of interdependency between apps if the URL format changes on a different version of Tapestry, and this doesn't account for authentication/security measures, but it's a start. /bd -Original Message- From: Valdemaras Repšys [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 18, 2006 5:27 AM To: Tapestry users Subject: Re: external link to a tapestry page Thanks for the answer, Aleksej.

Re: handling file downloads
I finally got back to this. I wrote up a service to send the csv files (using http://lombok.demon.co.uk/serviceHowTo/app - thanks Shing for the example - well done), which all works fine, but I have one question (which could easily be addressed by using the unsanctioned approach mentioned in the FAQ - thanks Nick). Imagine you've done a bunch of work in home.html/home.java to create a set of data. Now you're ready to save it as a csv file. You click on the link which invokes the csv service, but it's unrealistic to pass all the parameters needed to re-create the data set to the service, or to even pass the data set itself (via a parameter). Home.java, of course, knows all about this set of data (as does the session). So how can the service be told to get the data set from Home.java (or from the session)? One way around it seems to be to use a regular @DirectLink, which would create the file and then redirect to the csv service, which would then stream the file (instead of assembling it on the fly). It would be nicer though if it can be done without writing intermediate files. Any hints?

Re: handling file downloads
A possibility is to store the parameters (that are needed to construct the data set) in a session ASO. You can inject the above session ASO into your service. So that the data set can be constructed in your service when the service is called. Shing --- Julian Wood [EMAIL PROTECTED] wrote: I finally got back to this.

Re: A bit OT: how to manage database connections for multiple components rendered simultaneously.
1) To have 9 pages rendering simultaneously you need to have very very high traffic. 2) We have systems with 500 connections to the database running just fine. It is easier to throw hardware on a well-known problem (at least to some extent) than to spend cycles over-engineering. 3) Think of caching the data if possible or think of implementing an aggregator that can send a single request on behalf of all components and distribute the results to them. - Original Message - From: Rui Pacheco [EMAIL PROTECTED] To: Tapestry users users@tapestry.apache.org Sent: Tuesday, July 18, 2006 6:30 PM Subject: Re: A bit OT: how to manage database connections for multiple components rendered simultaneously. Still, if the components were all rendered at the same time, you would be tying up 9 connections simultaneously, and that would kill your response times.

So, you'd be okay with opening/closing 9 connections to the database during each request cycle? I'd think it would be better to just use one during the entire request cycle. -Original Message- From: kranga [mailto:[EMAIL PROTECTED] Sent: Monday, July 17, 2006 12:40 PM To: Tapestry users Subject: Re: A bit OT: how to manage database connections for multiple components rendered simultaneously. Even if all components ask for their own connection, assuming components release connections when they are done, you would still expect only 1 connection in use (though it may physically travel on upto 8 different connection, there is only 1 connection open at any given time). A much better optimization would be to add an observer/mediator style pattern - a data provider that each component is able to tell what data it needs (perhaps in the renderComponent method) and when the first request for the data is made, the provider creates a SQL encompassing all requests, gets it and is able to dish it out. However, I personally (without any more info) would classify this optimization as pre-mature. 8 requests to the database may only result in about 400ms while I have a monster elsewhere slowing everything down. Plus you need to take into account how often the index page is actually invoked. - Original Message - From: James Carman [EMAIL PROTECTED] To: 'Tapestry users' users@tapestry.apache.org Sent: Monday, July 17, 2006 11:36 AM Subject: RE: A bit OT: how to manage database connections for multiple components rendered simultaneously.

Hi all This is not a pure Tapestry question, but I believe you have seen this before and might be able to give me some guiding light. I have a web application, which I am splitting into several fragments, ie, components, each one rendering content stored in a database. I just realised my index page would have 9 such fragments and if each is to retrieve a connection from the pool to get its content, the stress on the db server might be crazy, even if each request is quite short. I have a connection pool, but even with that I don't believe its healthy to use 9 connections at the same time. What about the other users?

$template option using annotations
I've built a Border component using only annotations. I would like to put the .html template in /context/basic/Border.html. And in general I would like to organize my components in various directories as I expect them to grow pretty quickly. Is there an option for specifying the template location for a component using only annotations that is the equivalent of putting an asset named $template in the .jwc file?
