Re: detecting execution mode
Hi John,
you should be able to inject its value into your class with
@Symbol("tapestry.production-mode")
See org.apache.tapestry5.ioc.annotations.Symbol for documentation and
org.apache.tapestry5.SymbolConstants for names.

Re: Want locale to be part of every uri
Hi Nillehammer,
I was facing the same task and took the liberty of using your code -
works like a charm! Thanks for that!
One thing though... it will redirect with a "302 - Found" code, while
I need it to return a "301 - moved permanently".
Maybe it's because it is late, but I can't seem to figure out how to
change that. Do I need to add a custom ComponentEventResultProcessor?
For a custom result type, as "Link" is already being handled?
Or am I overlooking something?
I appreciate your help,
Lutz

Re: jsp & jstl in tapestry
Short answer: no. Long answer: well, you know, "impossible is nothing". I you really must, you could probably "mix" Tapestry templates and JSP pages in the same application, but I cannot think of a good reason why one should attempt this. What are you trying to achieve? Why not use just Tapestry, no JSP/JSTL?

Re: Is there any way to render the "get" method of form?
Dear Thiago, thanks for your patient reply and the advice. Of course I realize that I can still implement a search with Tapestry, with redirect-after-post or else, and I have actually done so in the past. But please take a minute and think about these two things: 1. You say, > GET was always meant to be used in request that don't change the state of > the application (including database) and this is exactly what I would like to use it for - as I said, a search. You could re-phrase your argument: "POST was meant for requests that do change the state." So why do I have to use it for requests that do not? 2. Of course, a lot of things are doable, change the DOM and what not. But wasn't the idea of Tapestry "make the simple things easy, the difficult things possible"? A form with method=get is totally valid HTML, and I think it should be easy, not complicated. These two reasons are why I said the lack of get-forms is "puzzling" me, it just seems somewhat inconsistent with the rest of Tapestry (which I use and will continue to use with great pleasure). I did as you told me and created a JIRA ticket (a "wish") for it: "https://issues.apache.org/jira/browse/TAP5-1285"; Keep up the good work, Lutz -- altocon GmbH http://www.altocon.de/ Software Development, Consulting Hamburg, Germany - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Is there any way to render the "get" method of form?
Dear Thiago, now this - the lack of - is something that has been puzzling me in Tapestry 5 for a long time. Why would you say using "GET" is a bad idea? The use case I think of is a search field. You enter a search term, submit the form, get the result. I think using a form with method=get is the absolutely correct thing to do to achieve this. Of course I am willing to learn. What would be the "Tapestry way" of implementing this? Thanks for your help, Lutz > > Using the GET method in forms is a bad idea.

Re: 301 vs 302 redirects due to SEO
Stephan, you can extend the possible return types of the onActivate method by adding a ComponentEventResultProcessor to you configuration. You can define an HttpStatusCode class that returns the code you wish. I don't know if you consider this "clean", but it takes HTTP internals, codes etc. out of you page class and puts it into the HttpStatusCode class or the result processor. See http://old.nabble.com/T5-How-to-tell-T5-to-send-301-%28moved-permanently%29-ts18870223.html Hope this helps, Lutz On Thu, Jan 14, 2010 at 7:28 PM, Stephan Schwab wrote: > > Event handlers in Tapestry, such as onActivate() may return a page object or > page name.

Re: Persisting state without HTTP Session
Jim, You still have some different options to pursue in a cluster.. - "sticky" sessions, so that requests of the same user will go to the same server in the cluster. Good for load balancing, but if a server fails, the users of that server will loose their session. - session replication in the cluster - this seems to be the approach you are thinking of. Here I would indeed imagine that the amount of data you store in the session heavily influences performance. - persist the session. Could be in clustered rdbms, could be one of these distributed key-value stores that are all the rage these days, like Cassandra or HBase. Maybe you could let us know what you ended up doing, once you've finished your project.

Re: Persisting state without HTTP Session
I see. There wouldn't be much handling, though, one could probably implement a "cookie" persistence strategy, so that you could use the @Persist annotation. Doesn't that even exist already? The thing you are in favor of, using post.. there'll be some disadvantages. I assume you won't be using redirect-after-post much, if you don't want to keep state on the server side. You would have to disable that, as it is the default in Tapestry. I could imagine having a central dispatcher... every post goes to that central dispatcher, the page to be rendered would be one of the parameters. The other parameters would constitute the context for that page. That would be kept track of with hidden form fields. Might be possible, but not a nice solution. No bookmarks, possibly no navigation with browser back - forward buttons.. You could write your context into a database after request processing, and read it on the next request. Of course that would be exactly the same as using a session (in fact, you can configure most servers to store the session in a database). Only slower (than in-memory sessions). Well, now we know why people came up with the session concept. It is actually quite a good approach. What was the reason again you don't want to use it?

Re: Discussion
Hi everybody, I think the discussion on TheServerSide actually is somewhat interesting, but not because of the unfortunate Tapestry vs. Wicket flame war. Let's have a look at the topic leading to that... - One part of Java EE 6 is "CDI" (JSR 299) - http://jcp.org/en/jsr/detail?id=299 - originally called "Web beans". I think it was inspired by Gavin Kings Seam Framework. - The reference implementation for that seems to be something called "Weld" - http://docs.jboss.org/weld/reference/1.0.0/en-US/html/ - Weld has Wicket support build in, and the examples are given in Wicket (although the Java EE "standard" would be JSF 2) because Wicket is easier to learn than JSF (at least Gavin King says so in http://in.relation.to/Bloggers/HowToStartLearningJavaEE6, but I think many would agree with that). So the interesting (to me, at least) questions are: - How does CDI relate to Tapesty and Tapestry IOC? - Should / could Tapestry incorporate / conform to CDI somehow? - Should we try to add Tapestry support to Weld? - Or is Java EE 6 / CDI just not relevant to Tapestry? I haven't really looked at Web Beans resp. CDI yet, but from first site, it defines some context scopes (request, session, application, conversation) and some annotation based dependency injection. Both areas are already covered by Tapestry (although afaik there is no conversation scope (yet) in Tapestry). So are CDI and Tapestry mutually exclusive? Or should Tapestry be refactored to use standard CDI annotations, so it can claim to be a CDI / JSR 299 implementation? I would love to hear your opinions about that.

Re: t5: T5 friendly e commerce software?
Hi Angelo, what kind of e-commerce software are you thinking of? If it is a straight-forward online shop - we built www.toplicht.de about two and a half years ago with Tapestry and ever since we did, we wanted to open source the code as a an open source e-commerce project (the name would be "Cokios", see www.cokios.org). We never really got round to it... and of course there would be some work left to do, remove customer specific code, create a sample shop, update to Tapestry 5.1... but still, I think it might be a good starting point, better than starting from scratch. If you would be interested in using and maybe even in contributing to an open source tapestry e-commerce software, I might actually start putting some code in the sourceforge repository.

Re: Running quickstart in tomcat from eclipse
Hi Sean, although I currently use jetty (via the jetty maven plugin) for Tapestry development, I have used tomcat in the past, and if I remember correctly, there are two approaches. You can use the "web tools platform" in Eclipse, which will give you a server view and allow you to start your web project with "run on server". Googling for "m2eclipse wtp" comes up with http://docs.codehaus.org/display/M2ECLIPSE/WTP+mini+howto, which should help. Alternatively, you could use the Sysdeo Tomcat plugin: http://www.eclipsetotale.com/tomcatPlugin.html Let us know what worked for you.

Re: T5： getting new Hibernate session in a lengthy thread
Hi Angelo, I think the point of sticking the session to the request is to keep it open until the request is processed, to avoid LazyInitializationExceptions during view rendering. So you might have to do your session management without the HibernateSessionManager. Then again, I wonder if it really makes much of a difference - if the database stuff is done in the request processing thread, what do you achieve by closing the session a tiny bit earlier than it would be by the HibernateSessionManager anyway? If the database update is really so lengthy, you might want to do it in a separate thread altogether.

Hi Dan, I think the usual approach would be to expose a remote interface to your application not through tapestry (or any other web framework), but by use of some remoting framework.

public RequestExceptionHandler
decorateRequestExceptionHandler(final Logger logger, final Response

Re: zone enhancements?
Fernando,
I agree with you, especially your suggestion (1) would be very helpful
and a welcome addition. The form/zone combination could maybe include
more callback hooks. I think I have a case of Rails envy, look at the
callbacks you can use for the remote_form_tag:

With this, you could easily show a DIV with a spinner gif / busy
indicator "after" the click, and hide it again when on "complete":
<% form_remote_tag :url => { :action => "search" },
:after => "Element.show('loading');
Element.hide('results')",
:update => :results,
:complete =>
"Element.hide('loading'); Element.show('results')" do %>
Oh, I'd love to have that in Tapestry. Doesn't Rails use
script.aculo.us, just like Tapestry? Wouldn't that be easy to
implement, given the hard part is done by script.aculo.us anyway? I've
never really looked at it, but I think the Tapestry tags don't produce
script.aculo.us code directly, the library is wrapped and thereby only
a reduced functionality is available. Thinking about it.. in
script.aculo.us, you can customize the effects (like the highlight and
fade) with parameters, such as hightlight time and colour. This also
is lost in Tapestry.
Assuming I would wish to extend the script.aculo.us integration, in
order to provide all those AJAX form callbacks, and effects
parameters.. what would be the way to go? What would be a good place
to start?
About (2) - I think that could maybe be more easily handled on the
server-side, using a transaction/synchronization token, like you would
to prevent regular forms from being double-submitted.

Re: T5/Jetty: disabling jsessionid?
Andy, you can strip the session id with filter, but you should also check if the pages you want index really need to be stateful. When your servlet container adds a session id, it means it found it necessary to create a session. If you just strip the session id, a new session will be created for every request from a search engine crawler, which is usually not want one wants, especially if you have a lot of pages. Tapestry makes it easy to make your pages stateless, since ASOs are not created before they are used, and you can check for existence before using (and thereby creating) them. That will also solve the session id issue, since for the stateless pages, a session won't even be created. Have you thought about that? hth, Lutz On Tue, Dec 30, 2008 at 5:13 PM, Andy Huhn wrote: > Hello, > > I'm having issues with the way my app is being crawled by search > engines.

Re: T5: encoding issues
Hm... I think there are many possible points of failure for the encoding... - maybe your browser thinks the page is not utf-8. Is the encoding set correctly either in a http response header or html meta tag? - what do you use for building your project? If you use maven, check the "encoding" argument for the compiler plugin configuration. If it is not set, maven will assume the source files are in the platform default encoding, no matter what eclipse says. Also, as a quick workaround, you could use the html entity ° and use t:outputRaw instead of the $ notation. hth, Lutz On Tue, Dec 23, 2008 at 10:24 PM, Christoph Jäger wrote: > Hi José, > > the java files seem to be UTF-8.

That's all a bit confusing... if you use onEvent with event=change, of course you also use the "onchange" event. The change event will cause an ajax call that will cause some code on the server to be executed, and may return a result, which may be passed to a "callback" JavaScript function. > Now I am using a combination of both OnEvent and onchange.

That might get messy, how can you define which one is triggered first? Plus, when you submit the form anyway, why the ajax call? > I am hoping someone can point me in the right direction if there is a more > conventional way of updating a form based on a user's actions. Otherwise I think you should go back to using the OnEvent mixin, without additional onchange calls such as a form submit. Have your event handler update your data on the server side, have it return some value that allows you to update your other select, and write a JavaScript function that does the update. > The only other thing is if I initialize the customerSelect in onActivate the > select is always one selection behind (ie. I choose a customer and when the > page refreshes the select component is not updated, I then choose a > different customer and the select is updated with my first selection... ) That sounds odd. Maybe the onActivate you expect to be called is not called at the time you expect it. You should trace/debug the invocations. > I would love for this to work with AJAX using the OnEvent mixin and an > onCompleteCallback javascript event, Should not be a problem.

Re: JSESSIONID cookie, secure is set, how to not set
I don't know how to do it within Tapestry, but generally you can use a
filter to make sure that jsessionid is never set as a secure cookie. I
dug up some old code that does that, I think it works:
public class TomcatUnifiedSessionFilter implements Filter {
public void destroy() {
// nothing to do here
}
public void doFilter(final ServletRequest request, final
ServletResponse response, final FilterChain chain)
throws IOException, ServletException {
/*
* Tomcat tracks the session using the JSESSIONID. When the session is
* created as a consequence of a request of a secure page, however, the
* "secure" attribute of the cookie is set to true. That prevents the
* session to be consecutively tracked on non-secure pages. We would
* like a unified approach, though.
*/
final HttpServletRequest httpRequest = (HttpServletRequest) request;
final HttpServletResponse httpResponse = (HttpServletResponse) response;
// TODO: some more explanation
final HttpSession session = httpRequest.getSession(false);
if (session != null) {
final Cookie sessionCookie = new Cookie("JSESSIONID",
session.getId());
sessionCookie.setMaxAge(-1);
sessionCookie.setSecure(false);
sessionCookie.setPath(httpRequest.getContextPath());
httpResponse.addCookie(sessionCookie);
}
chain.doFilter(request, response);
}
public void init(final FilterConfig config) throws ServletException {
// nothing to do here
}

Re: T5: spring integration question
I'm just taking a guess here, but I think it won't. As far as I know the tapestry spring integration was always limited to singleton beans. I think the "prototype" variant is maybe difficult to handle since tapestry ioc (and hivemind in the past) have a somewhat different approach on object creation, using pooling and all, afaik. I never really considered that a big drawback, though. Plus, apparently you can just inject the application context and get your prototype beans from there. See http://tapestry.apache.org/tapestry5/tapestry-spring/ , last sentence.

Re: T5: CMS Integration
Dear Mr. Mason, > Tapestry features so I can't us a conventional CMS like Magnolia. Has > any one else had any success with this sort of integration. yes, we had. If you look for example at "www.go7seas-kreuzfahrten.de", you will see a "hybrid". The cruises, the booking process, ship and journey information are all part of a tapestry application. All the pages in the "Information" and "Service" areas are maintained by the customer using the Magnolia CMS.

I realise I could make changes to the tapestry code I think the approach you describe is very well possible and would not even involve any "low-level" changes or overriding services using tapestry-ioc. One would have to implement a number of Tapestry components that mirror the functionality given in the Magnolia JSP tag library. Actually, I wanted to start an effort to do just that a long time ago: "http://sourceforge.net/projects/tapestry-jcr/";. I haven't found the time yet, though. However, the approach has the drawback that you will have to maintain two versions of your templates - a JSP-based one for Magnolia, and the Tapestry ones. Basically, you'd have every page twice. That's why we chose a different approach. We use Magnolias output as the input for Tapestry. That is, the rendered Magnolia page is actually a Tapestry template. Since Magnolia uses JSP, these to approaches don't interfere. You can easily add t:ids and such to your Magnolia templates. You can use Tapestry's template location mechanism to get the pages from Magnolia, and put any pre-generation and/or caching in between.

Re: [T5] setup logging
Hm... I had the same problem once, and I figured it was because Tapestry doesn't use the log level configured for the "org.apache.tapestry5" category, but the level you define for your components. As it is said on http://tapestry.apache.org/tapestry5/guide/logging.html : When a component's logger is configured at the DEBUG level, you will also see added output when the class is first accessed identifying how Tapestry is modifying the bytecode of the class. That is something I find quite annoying and don't see much use in, by the way. Anyway, for me it worked using a log4j filter, as described in an earlier conversation on this list, see http://www.nabble.com/T5%3A-How-to-configure-T5-not-to-display-unwanted-log-td16024408.html I don't think it makes a difference if you use logger or category in your log4j.xml.

Re: T5: Trigger zone reload with just javascript?
Hi Mike,
I faced the same task, I solved it using the onEvent mixin from
Tapestry 5 components -
http://87.193.218.134:8080/t5components/t5c-commons/ref/org/apache/tapestry/commons/mixins/OnEvent.html
In more detail - say you have two selects, sel1 and sel2, and you want
sel2 to be updated when sel1 changes.
Add the mixin to sel1:
...
...
In your component class, implement a method that returns the options
all in one string, seperated by some characters not otherwise used in
your labels or options. For example, you could use ";" between labels
and options, and "||" between the label - option pairs.
@OnEvent(component = "sel1", value = "change")
public StreamResponse selectionChanged(final YourClass parameter) {
... do something with parameter..
... build list of label - option pairs..
for (i...) {
pair[i] = label + ";" + option;
}
return new TextStreamResponse("text/html",
StringUtils.join(pairs, "||"));
}
Tapestry type coercion works for your parameter, but the return string
you have to build yourself.
Finally, the callback function in Javascript looks like this:
function populateSel2(response) {
document.getElementById('sel2').options.length = 0;
// Split the response
returnElements = response.split("||")
// Process each of the elements
for ( var i = 0; i < returnElements.length; i++) {
valueLabelPair = returnElements[i].split(";")
document.getElementById('sel2').options[i] = new Option(
valueLabelPair[0], valueLabelPair[1]);
}
}
I should mention that I picked that function up somewhere on the
internet, i didn't write it myself.
Anyway, hope this helps,
Lutz

Re: T5 How to tell T5 to send 301 (moved permanently)
I haven't tried it, but I think it should work with the approach described in http://www.nabble.com/Index-page-context-and-404-response-to16649174.html#a16649174 It works fine for 404, you might have to extend it to include the URL to the page you are redirecting to.

Re: https actionlink
Hi, have a look at "http://tapestry.apache.org/tapestry5/tapestry-core/guide/secure.html";. If the first paragraph - @Secure - does not work for you (which seems odd by the way because for me it seems to work just fine in 5.0.13), you can configure it in your AppModule.java, see the other two paragraphs of the page.

Re: T5 getApplicationName
Hi Argo, if I understand you correctly, what you call application name is usually (or, in "java servlet speak") referred to as the "context". It is a property of the HttpServletRequest, which provides that information to you by the method "getContextPath()". Check the following pages: http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/http/HttpServletRequest.html#getContextPath() http://wiki.apache.org/tapestry/Tapestry5ObtainingHttpServletRequest Hth, Lutz On Mon, Aug 4, 2008 at 6:56 PM, Argo Vilberg <[EMAIL PROTECTED]> wrote: > hi, > > > How to get Application Name in tapestry framework. > > http://localost:8080/appname/start > > appname?? > > > > Argo > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[T5] FormFragment and Radio Button - hidden Fragment still validated? (5.0.13)
Hi, I'm trying to use a FormFragment triggered by a Radio Button. Obviously, other people have done this before and ran into issues, see http://www.nabble.com/Form-fragments-and-radio-buttons-td16493007.html#a16493007 and https://issues.apache.org/jira/browse/TAPESTRY-2261 Having read that, I was under the impression that these issues have been resolved and it should work just fine in 5.0.13 (which is the version that I'm using). What I am experiencing now, though, is that showing and hiding the FormFragment works fine, but if the fragment is hidden, the fields are still validated on the server side. The desired and documented behaviour should be that validation only occurs when the fragment is visible to the user. Now I don't know if I should file a JIRA issue for this or if I'm just not doing it right, or maybe not using the right Tapestry version. So please help me out: Has anyone successfully used - and experienced the correct behaviour regarding server-side validation - a FormFragment triggered by a radio button?

Dear Chris, > Ends up as http://app.com/. Am I doing something wrong? Surely others > have run into this and deem it undesirable, no? yes and yes. It has been discussed on this list before and a workaround (that works well for me) has been proposed. You can see the thread here: http://www.nabble.com/Index-page-context-and-404-response-to16649174.html#a16649174 Described very roughly: Assuming your index page is not meant to be called with parameters - if parameters are given, the user was probably actually requesting a non-existing page. So if index is called with parameters, reply with a 404 not found. Hth, Lutz - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: What if "Page" was removed from page names?
Shouldn't that be up to the developer (or whoever decides on the URLs)? If you don't want the page suffix, why not just name the page "Blogger" instead of "BloggerPage"? What if I wanted a url that reads "mypage"? Would I have to name the page "MyPagePage"? I'm all for convention over configuration, but here I feel some arbitrary rule would be unnecessarily imposed on the developer.

[t5] form method="get", "old school" query parameters

Re: T5 turn off form validation
Well, if you want stateless, you probably don't even want the session to be created at all. There has been a conversation about this on this mailing list before. The solution takes advantage of the possibility to define the persistence strategy per component. It also provides a custom persistence strategy that only stores the tracker if errors have actually been found. See http://markmail.org/message/jfmxfsjgiy3msnhf I could imagine another good way to do: create your own "StatelessForm" component. I don't know how much work that would be, though. If you create such a component, please post the code on this list or on the wiki! Hth, Lutz - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [NOOB] Getting the Locale without injection
Hi, which Tapestry version are you referring to? And what exactly do you mean with "in a final object" - are you talking about a component? In what way is the "final" part relevant?

Re: [T4.1]Returning a list to a page
I'm not sure if I understand that correctly... I think the idea was
not return the page name as a string from a submit method, but to set
it..
in page A:
- inject page B
- set the name of page A as a property in page B
- activate (or redirect to) B
in page B:
- do not inject page A, but get it by name through cycle.getPage..
- set the list as a property in page A
- activate (or redirect to) A
To add to the confusion.. if you access that list from many pages,
wouldn't it be better to store it as an application state object
(ASO)?

Re: [T4] Tapestry-Acegi error

Re: [T4] wierd ognl error
Excuse me for being picky, but your subject is misleading. You claim to have an ognl error, but obviously you are using tapestry-prop instead of ognl. >From a quick look at your code I would guess the problem is that at some point the value of radioId is "mnpnull". Although you have defined an initial value, it is not immutable and can take on other values of type string, I guess. If you think that's unlikely, you could also try to actually use ognl instead of prop, just to make sure it's not a shortcoming of tapestry-prop you're facing.

Re: [t4] How do I inject arbitrary services into a custom service encoder?
Hi there, to me it seems the error message indicates that you don't have a method "setSpringContext" in your CurrentFooEncoder. I think hivemind will try to set that property using that method. Or maybe you need a constructor with an argument of that type. For a slightly different approach you might want to look at the tapestry-spring library at http://howardlewisship.com/tapestry-javaforge/tapestry-spring/. That will allow you to reference objects defined in your spring application context in your hivemodule.xml using the spring: - prefix. I'm not sure how the syntax would be for your encoders, though. I think you could just create an instance, and within the class you can inject spring objects using the @InjectSpring annotation. I use it in some places, works great, just can't seem to remember the syntactical sugar..

Re: T4.1: How do you combine Tapestry + Spring?
What is the most common way to use Spring in combinations with Tapestry? I don't know. How do you combine Tapestry and Spring? I use the tapestry-spring library from "http://howardlewisship.com/tapestry-javaforge/tapestry-spring/";. Which parts of Spring? I use dependency injection a lot, plus some of the database/hibernate support stuff (I let Spring handle transactions, OpenSessionInViewFilter), Please share some of your experience with me :) It works well, but then again, I don't think I tried anything too fancy.

Re: ForBean issues
I've been using Tapestry for a couple of month now and still haven't
understood how to work with collections in forms correctly.
What works well for me is the DefaultPrimaryKeyConverter. But it seems
such an overhead, I have to populate it in the beginPageRender, and
iterate it in the listener to update my original collection.
In the "Enjoy.." book by Kent Tong, he demonstrates using an
InvokeListener and calling a listener on every iteration, to process
the current item. Again, that seems odd to me, especially when you
want to delete items.
I also just used a list as source and the index attribute, it seems
Tapestry updates the items "in place" during rewind, which is fine.
But I don't understand how I can avoid the items being serialized into
hidden fields if I choose this approach.
Having said all that, I would like to add that I'm not new to
programing or Java. Quite the opposite, really, but I find Tapestry is
not very well documented in some areas (or the documentation is very
hard to find).
Anyway.. about your code: obviously, I can't tell you which is best.
But I think you don't have to pass your items as a parameter to the
listener method. Instead, the form fields (in this case, the
collection) will be bound to an instance variable in your page object.
Maybe you should drop that parameters attribute in the @Submit.
But you have to make sure the list is not null during rewind, and has
the right length, so you have to refill it before the rewind, and the
values will be overwritten during rewind.
The listener method that is called will be the one referenced in the
@Submit component. In your case, the one referenced in the @Form is
never called, I think. So you might want to lose on of those two, to
avoid confusion.
That's about all the advice I can give you let's just hope someone
who really knows let's us in on some "collections in forms" insight.

Re: CMS Integration
Simeon,
it would of course be great if you'd provide your code.
I wasn't aware you had already done some work in the area, only today
by means of google I read your posting from november 05. What is the
status of your code? Is it currently in use with alfresco? Have you
tried it with other JCRs, such as jackrabbit? Is it available for
download anywhere? Apparently, there is a handful of people interested
in JCR access through Tapestry, so I think we should set something up.
If it wasn't for you mail, I would have created a "tapestry-jcr"
sourceforge project
and would have started working on the functionality your code
apparently provides. I have little time to spare for it, though, so to
start of with already working code would give it quite a
boost. But I don't want to "steal" your project from you - maybe you
want to turn it into a sourceforge project yourself? I'm sure people
will use those components and you'll get a lot of credit for it.
Well, if you don't, let me know. In that case I'll be happy to start a
project based on your implementation.

Re: CMS Integration
Hi,
I haven't really looked at it, but I was wondering... as far as I
understand, you'd like to integrate CMS-managed content into a
Tapestry-based site.
You mention Magnolia... afaik, Magnolia uses a JSR 170 compliant
content repository, such as Apache Jackrabbit
("http://jackrabbit.apache.org/";), to store the content.
It provides a number of JSP tags to access that content from within
your page templates
("http://magnolia.sourceforge.net/30/taglib/intro.html";).
It seems getting content out of Jackrabbit is not all that hard. So
here's my idea: Why don't we start a project to build some Tapestry
components to access content repositories that conform with JSR 170? A
possible approach could be to re-implement the Magnolia JSP taglib, or
parts of it, as Tapestry components. Or maybe Stitches could be used
as a starting point.
This way, I would think, you could use any JSR 170 compliant CMS to
manage your content, and could integrate the content in a Tapestry
based site using this new component library.
What do people think? Is that realistic? Would it work? Would such a
component library be of interest to anyone?

I think it would be easiest if everybody would just list their

Re: R: R: Not solved! Re: Problem with mixing HTTP and HTTPS
I have not used google analytics, so I don't know. In theory, it could/should still work. The original client ip is, afaik, included in the http header "X-Forwarded-For". It's pretty much as if the user uses a proxy server (i.e. a forward proxy, not a reverse proxy) - how does google analytics deal with that? Plus, I think they use cookies for the actual tracking, those should not be affected. But as I said, I have never used it, so I really can't be sure. I used mod_proxy it in the past to include some snippets provided on a site via plain html inside an https page.

Why would you not want to use an external mechanism? Is it not rather
a feature of the framework to be "SSL agnostic"? I think more often
than not people would keep, for example, security and access right
aspects out of the application and deal with it declaratively. Now
you're looking for a way to move http/https - switching into your
application?
Well, anyway: with Apache httpd, what you try to achieve is often done
by using mod_rewrite. For https-only pages, the protocol part can be
rewritten to https if the page is accessed via http, and vice versa.
If the URL rewrite filter ("http://tuckey.org/urlrewrite/";) does what
it aspires (to be a very powerful tool just like Apache's
mod_rewrite), it should allow you to do the same in a more portable
way.
Talking about apache: including external content on https sites via
http can in many cases be done without triggering warnings, by making
a directory on your https server a reverse proxy using mod_proxy.

Re: Hibernate persisted data never makes it to DB
Mark, I added "hibernate.connection.autocommit=true" to my hibernate.properties and that fixed it... hm. I don't know if that's a good idea. I'm not comfortable with hibernate.properties in a Spring environment, anyway. Is it clear to you in which order they are read? Will Spring configuration override hibernate.properties, or the other way around? And about this property: if it was set to or defaults to false, it probably does so for a reason. Why is that so, and why does noone else besides you experience the behaviour you experience? Still a lot of questions unanswered... So I assume Spring by default does no Session/TX handling, unless I use the HibernateTransactionManager or do programmatic transaction handling... Well, that's not quite possible, is it? Of course it handles sessions and transactions, it's not just a mock-up, you know. Talking about transaction managers - what do you have configured there? I said this in every post on this topic so far, and this being the last one I will say it just once more: Do check your applicationContext.xml. I'm sure you'll find the reason for the undesired behaviour in there. Your setup is configured in a way that it does not show the default behaviour. One last question, to get back to Tapestry - is Spring's OpenSessionInViewFilter going to work with Tapestry without limitations? Afaik yes. What limitations where you thinking of? I can't think of any right now. I don't understand the apparent popularity of it, though, I think it's not that good a concept. I see all these posts about Tapernate and others, but I'm not sure whether OpenSessionInViewFilter will work... I might be mistaken, but I thought Tapernate was about providing a Hibernate session factory through hivemind, allowing you to inject it into your Daos *without* Spring. Plus some extra stuff for convenience (similar to the OpenSessionInViewFilter from Spring). What is the benefit of "Tapernate" when you are going to use Spring anyway? Maybe someone could enlighten me on this? regards, Lutz - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Hibernate persisted data never makes it to DB
I asked for applicationContext.xml, and I get a mysql log... well, near enough :) From your last mail I understand you have the same problem if you use the mysql command line client. Makes me wonder why you thought the problem had to do with Hibernate in the first place (let alone Tapestry, for this Tapestry mailing list this has been OT for a while now...). So generally, your sql statements never get committed... which is weird, because by default, mysql starts new connections with autocommit enabled. If you connect to mysql from the command line and do select @@autocommit; what do you get? About your Hibernate configuration, since you use Spring anyway, I would recommend you use Spring for the datasource setup, makes it easier to switch, plus it makes sense (to me, anyway) to have it in the same place as the SessionFactory. Oh, and although the classname you use for the jdbc driver still works, since the mysql connector/j provides backwards compatibility in this respect, nowadays people tend to use "com.mysql.jdbc.Driver" because of a name change four years ago. lutz - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Hibernate persisted data never makes it to DB
Yes, the Spring HibernateTemplate will take care of that for you. The
actual behaviour depends on your transaction management, but let's not
get into that for now.
So, the save you call will commit the changes to the database.
Hibernate then disconnects the session, I believe, anyhow, there is no
need for you to add extra code.
Since you even flush your session, there is no doubt Hibernate will
try to store your object in the database. Even if it doesn't work, you
should get some exception.
So...
- have you checked the rest of your code? Are you sure this piece of
code is actually called? Step through it or add debugging output.
- if you're sure your application is otherwise correct, the code gets
executed with the room object you intend it to, and you still don't
have anything in your database, I believe you have something severely
misconfigured and suggest you post your configuration.
That would be the part of your Spring applicationContext.xml (or
whatever it is called in your case) where you set up the data source
and the session factory.
some more comments...
I figured since everybody has problems with Spring closing sessions too
early and thereby causing problems with lazy-load, it should not affect
me in this case and actually work for me.
But maybe not???
Since you have no problem with lazy loading, in fact, you are not even
loading, I believe keeping the session open until the view is rendered
will not help you.
The Page gets the Service (a singleton SpringBean) via tapestry-spring
library ("spring:...").
The Service gets a DAO through Spring IoC.
Just out of curiosity: Why do you not inject your Dao into the page?
What does "the Service"? do?
So I guess the DAO is a singleton that opens a session once and never
closes it? Does that mean that everything is one session/transaction,
across all requests and user-web-sessions?
No.

Re: Hibernate persisted data never makes it to DB
my two cents, in three parts... - about the problem: well, usually, it kind of works. This may sound silly, but do you maybe have hbm2ddl.auto set to "create-drop" ? Or when you check if something has been stored, are you sure you're checking the right database? I'm not making fun of you, I have seen these things happen, to very smart people. One more: are you using the HibernateTemplate from the right package (there is a hibernate and a hibernate3 package. Actually, I don't know what happens if you use the wrong one, might even work). Anyhow, if nothing is stored and yet you don't get any error message, I guess you have to recheck your configuration carefully. - about the log file location if you just give the filename, it will be created in the current working directory. If you start Tomcat from the command line, that will be $CATALINA_HOME/bin. If you start it using the Eclipse plugin, the location is, well, eclipsed - I have not managed to find it yet. Anyhow, both variants are not very desirable, so you might consider providing an absolute path to your logfile (as in /var/log/hibernate.log). Personally, on my development machine, I just log to stdout. - about the "wanting to know the internals": don't get me wrong, no offense intended, and it's really none of my business, I just can't keep the thought to myself: I think it is a very valid standpoint, but I also think it is slightly contradictory in your case. You claim you want to know internals, but yet you use the Spring HibernateTemplate? Isn't that all about hiding a lot of internals? hth, Lutz - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

IRequestCycle.sendRedirect() because I remembered seeing that somewhere in

it in the JavaDocs, but where in the heck does one find that you can specify
IRequestCycle as a parm on a java method?
for example I found this in the mail archives:
public void validate(IRequestCycle cycle) {

}
I assume it should be in the user guide, but where? It would rock to have a

Re: Tap 4 integration with Spring and Hibernate
About Spring: There is a Wiki page at "http://wiki.apache.org/tapestry/Tapestry4Spring"; and a "drop-in" jar at "http://howardlewisship.com/tapestry-javaforge/tapestry-spring/";. The latter is by the Tapestry author himself, which makes some people (including me) favor it among the "quite a few solutions found on the net". If you use that, you will probably configure Hibernate using Spring, so you don't really integrate Hibernate with Tapestry, as that is done indirectly via Spring. If you only need Hibernate and Dependency Injection, you could achieve that without Spring. I believe Tapernate, mentioned in the other replies, offers a solution for that based on Hivemind.

No, but it is implemented in AbstractComponent:

otherwise we'd be getting quite some exceptions. I can't see why that

There is no obligation to use Hivemind if it is not appropriate to
your problem. Hivemind is useful for decoupling parts of the system,
and for making "aspecty" customization that cut across the framework.
If you don't need decoupling, and don't need to customize across the
whole framework, perhaps you don't need to bother with Hivemind.
So there may be a Hivemind way to inject a different message worker
into only certain classes, but I would guess overriding getMessages()
is probably just fine. Did you try it? Does it work? Is it simple? If
so, no worries!

Re: component that will get localized resources from database?
Hi, actually no, I haven't even tried it, but it *must* collide with the enhancement stuff... However, I came across the page "http://wiki.apache.org/tapestry/UsingCustomResourceSource";, which provides quite a good solution. It "overrides" a default service implementation with a specific one in the applications hivemodule.xml. Kind of obvious, only I just didn't know if and how it works in Hivemind. Thanks to "http://jakarta.apache.org/hivemind/override.html";, that's clearer now. And instead of the InjectMessagesWorker it overrides the ComponentMessagesSource, which is probably also a good idea. So I'm almost there. The only question remaining is: If I understand correctly, this will affect *all* components. Is there a way to achieve this behaviour just for my own, custom components?

Hivemind is useful for decoupling parts of the system, and for making "aspecty" customization that cut across the framework. If you don't need decoupling, and don't need to customize across the whole framework, perhaps you don't need to bother with Hivemind. So there may be a Hivemind way to inject a different message worker into only certain classes, but I would guess overriding getMessages() is probably just fine. Did you try it? Does it work? Is it simple? If so, no worries! Cheers, P - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
component that will get localized resources from database?
Hi there, assume you want to create a localized tapestry application, but there are localized messages that you don't want to store in a properties file / text file. In a plain Java application, you could just write your own implementation of ResourceBundle, that could take the messages from anywhere, e.g., a database, and use that instead of PropertyResourceBundle. With Tapestry, it seems to be more complicated, though. If I understand correctly, the "AbstractComponent" is "enhanced" by an "InjectMessagesWorker", as defined in "tapestry.enhance.xml". The "InjectMessagesWorker" will inject a getMessages() method that will return the result of ComponentMessagesSource.getMessages(IComponent). Now, that's not what I want... A straight-forward approach would be to override "getMessages()" in my own component. Would that work? To me it seems to collide with the Hivemind enhancement/injection approach. Alternatively, I could probably change the InjectMessagesWorker to something of my own liking. But that would affect *all* components (that inherit from AbstractComponent), while I would like the modified behaviour just for my own. Plus, I don't really want to mess with the "tapestry.enhance.xml", since it is part of the packaged Tapestry distribution. So what would be the proper way to do it? Can I override the "inject-messages" command from "tapestry.enhance.xml" for my own components? How?
