JMaki with Tapestry 5
Good Morning group, I am trying to use JMaki with Tapestry 5 and was wondering if any brave soul tried to incorporate JMaki with Tapestry 5. Quick web search revealed that JMaki can be integrated with Tapestry 5, but I havent seen any example or posts about it. Please advice/guide me in the direction where I can use JMaki widgets in Tapestry 5 pages. Thank you in advance.

Re: Return page from ajax request
Despite the workarounds I think it would be much nicer if tapestry
could handle this automatically and don't force the developer to think
about that.

Re: T5 : Expanding Messages Catalog for localization from arbitrary source
Hi, Hannes!
I tried your implementation, and it worked right away, I just returned the
value TESTING TESTING from my DbMessages class that extends Abstract
Messages.
But, what I need is for the valueForKey(String key) method to be aware of
the languageId/customerId of the currently logged in user. In all my other
pages, I get this through injecting the request and getting my user object
from HttpSession. Alternatively this can be moved to an ASO, but I haven't
taken the time to do that yet.
I've tried injecting HttpServletRequest and ApplicationState on all the
classes listed in the implementation from Hannes, but none of them work
(only null values). How can I make information from the current user session
available to my AbstractMessages implementation?
Regards
Inge

I tried the route with the Decorator once, and ended up having to write
some

Your example worked great, i only had to pass some more Services
(AssetSource to get the URLs, my ProjectContextProvider to get the
ResourceBundles for my text) into the build-Method in AppModule, then i
could return the value for a Message-Key from the bundles, or if not
existant, from the fallbackMessages.

Hi
I have recently wondered about the same, and have now built something
that after much trial and error now works.
Basically, I have created a Messages implementation that wraps both a
tapestry Messages object and our own database messages. If a message is not
found in our database, the default Messages object is queried.
To get Tapestry to use my Messages implementation i had to decorate the
ComponentMessagesSource (and ValidationMessagesSource), since it is not
possible to replace the one in Tapestry. I think I read about decorating
services here:
http://tapestry.apache.org/tapestry5/tapestry-ioc/decorator.html and on
the mailing list.
My messages source service doesn't implement the ComponentMessagesSource
interface. I use an interception object for that. Hopefully you can
understand how it works from my example code below:
public class CommonsMessages extends AbstractMessages {
private Messages fallbackMessages;
protected String valueForKey(final key) {
... logic to get key from db, use fallbackMessages as fallback...
}
}
-
public class CommonsMessagesSource {
public Messages getMessages(Locale locale, Messages fallbackMessages)
{
... code that creates a CommonsMessages object, with
fallbackMessages ...
}
}
// This is the decorating class
public class CommonsComponentMessagesSourceInterceptor implements
ComponentMessagesSource {
private final CommonsMessagesSource service;
private final ComponentMessagesSource delegate;
public CommonsComponentMessagesSourceInterceptor
(CommonsMessagesSource service, ComponentMessagesSource delegate)
{
this.service = service;
this.delegate = delegate;
}
public Messages getMessages(ComponentModel componentModel, Locale
locale) {
return service.getMessages(locale,
delegate.getMessages(componentModel, locale));
}
// Not sure about how I should handle this one
public void addInvalidationListener(
InvalidationListener invalidationlistener) {
delegate.addInvalidationListener(invalidationlistener);
}
}

In AppModule.java:
// Method for instantiating and configuring the custom messages

public static CommonsMessagesSource buildCommonsMessagesSource()

CommonsMessagesSource messagesSource = new
CommonsMessagesSource();

This is how I got it to work, there may be other ways ofcourse. There
might even be better ways :-)

Re: T5 : Expanding Messages Catalog for localization from arbitrary source
Hi Inge,
glad to have been able to help you!
For your current problem, I can see two immediate solutions.
1. Store your user object as an ASO and inject ApplicationStateManager
into your Messages implementation. Get the user object instance by
calling applicationStateManager.get(UserObject.class).
2. Inject RequestGlobals in your Messages implementation. Then you can
get the request by calling requestGlobals.getHTTPServletRequest().
I hope this helps

T5 : Let's write a book !
First of all, I apologize for the long post in advance, I couldn't figure out how to make it shorter. I've been thinking about how much I miss the unborn T5 in Action book. I spoke to Howard a while back and he said that it's unlikely that a new revision of the Tapestry In Action (from Manning) would happen : understandably, he has the framework to worry about, not the books, and it's unlikely that he'd have 1 year to take away from work and write a book. Thus, I've been trying to figure out ways to substitute for the missing manuscript. Here are my impressions so far: * The T5 book from PacktPub is a nice intro, but it's out of date and it's kinda shallow * The wiki has some nice content on it, but it's disorganized and a little too random: you may find something useful on a subject, and then, you may not * The project docs are often quite useful and often times quite deep, but they don't have enough examples to put things in context * The tutorials are all focused around getting started, and don't have enough substance * Finally, the example apps (e.g. JumpStart, t5-acegi example, shams, etc) are extremely useful; however, (by design) there's little narrative surrounding them to explain how and why things work the way they do. Thus, the bottom line is that one has to hunt down 5 different resources (possibly more) to pull together a coherent picture , especially when one goes deeper than the getting started stage. Now, I clearly don't know enough about T5 yet to write a book myself (as much as that sounds appealing to the ego) and it's unlikely that I could possibly dedicate the time and effort to do it all. So, I had the idea for a while that it would be extremely cool and useful if a bunch of the people interested in T5 could get together (incl. myself) and write a book on the subject. Tim Sweetser jumped in with the idea on the IRC channel that we could do a collaborative online book : put together a rough outline of the potential content (chapter and section-wise), then let users contribute to the effort by filling in the blanks (with some editorial oversight). So, if something like this were possible, a bunch of people can get their minds together, each one contribute a chapter or two and kick off the effort. This way, each one person can focus on a subset of the problem, describe it in sufficient depth (e.g. research the areas that he/she is unfamiliar with), and not weigh down anyone in particular with an enormous amount of effort (such as writing a whole book). Surveying the landscape, similar things already exist. Tim Sweetser mentioned that Django did something like this. I know that Grails has quite a thorough user manual that covers most of the important areas of the framework. I also remember bumping into the PHP manual where people could comment and add relevant examples and such. So, in conclusion, this is possible, people have definitely done it, and it's HUGE for the community around the project. So, the next question is, how should something like this be done ? * The Wiki seems like a no brainer to start with, add the TOC and then allow people to contribute. The potential problem with it is that code and the examples can easily become stale. I know that the examples of the Grails user manual are somehow compiled and checked that they run before a new version of the manual is published. * Another option seems to be putting a bunch of Docbook files in SVN and collaborating through SVN to move the book forward. The upside of doing something like this is that it gives us an immediate perk of being able to export a printable version of the book. Downside is that contributing to the book is not all that easy (e.g. some DocBook knowledge needed, SVN access, etc) * Yet another option could possibly be Google Docs. The upside of this is that the learning curve is about 0 and publishing it in some decent format is easy. The downsides are that possibly can be a PITA to share the doc w/ the right people * Tim mentioned that maybe some kind of CMS would be nice, but at the same time, it might be a bit of an overkill. So, in summary, here are a laundry list of requirements: * The book should have thorough coverage of the different aspects of working w/ T5 : from getting started to components and advanced topics (e.g. IoC magic) * The book should be easy to contribute to - comments, code examples * It would be nice if there is a decent printable version * It would be great if we can leverage some of the existing resources: e.g. wiki, example apps, tutorials, etc. * It would be nice if we can come up with a way to keep the code in the book in working order (e.g. if we reference some of the example apps, that could do wonders in keeping a runnable version of the examples) * There should be some structure in the book (e.g. more than just the flat wiki namespace) * There probably should be some editorial oversight to prevent one of the known trolls from putting garbage in. So, here come the
Re: T5 : Let's write a book !
It is certainly an interesting idea. I think HIbernate follows a similar approach; they have a Wiki (Confluence, perhaps) and they scrape it to get the packaged documentation. We could look into running a more involved Wiki, perhaps from tapestry.formos.com. Confluence would be reasonable, as I can get an open-source project license for any of the Atlassian products. The problem with this is oversight; writing a book in any format consists of a lot of dull work. In an open community its hard to motivate people, without a direct stake, to do that kind of dull work.

Re: T5 : Let's write a book !
I agree that getting people to do boring tasks for free might be a challenge. But it's definitely worth a try. I think DocBook Wiki(http://doc-book.sourceforge.net/homepage/) could help here. You get the ease of use of a wiki and are still able to keep the content in docbook format so that it's easy to export to a printable version.

T5: How to implement a simple API servlet?
Guys, I've been trying to search google and nabble for this, but just couldn't find the answer, perhaps I'm just using the wrong keywords or something... as I'm sure it will sound trivial to some of you. Here's what I'm trying to achieve: I'd like to implement a simplistic API in our webapplication using just a plain old servlet to handle all API method calls. The idea is to just call this single servlet, passing in the required set of parameters via GET/POST, and responding with a either an XML data response (text/xml), or a binary stream (zipped data) depending on the method called. Now, I'm lost trying to find the best way how to mix this into the existing Tapestry5 application. I have tried to just add the servlet/mapping into web.xml but that doesn't work. I thought about extending TapestryFilter to ignore the API servlet's path, but the doFilter method is final right? I also thought about just getting the raw http request/response within a tapestry page using injection, but that just doesn't feel right - it seems better to bypass tapestry altogether for this purpose, or is it wrong? Thanks for any ideas in advance!

I did some modest work like this many months back, where I had a page as a kind of RESTful service endpoint. I returned a StreamResponse from onActivate(). The page didn't even have a template. This is not quite what T5 is intended to do, but you get the benefits of live class reloading and IoC integration, so why not?

At least with GET, You could do this with a Tapestry page class returning
a StreamResponse in its onActivate() method. Way easier than writing a
servlet.
More information here:
http://tapestry.apache.org/tapestry5/guide/pagenav.html (StreampResponse
section)
One example here:
http://wiki.apache.org/tapestry/Tapestry5HowToCreatePieChartsInAPage. The
example generates images, but it can be used to generate any kind of
response.

You don't need to do this. Read the Ignored paths section of
http://tapestry.formos.com/nightly/tapestry5/guide/conf.html. Short
version: add this method to your AppModule class:
public static void
contributeIgnoredPathsFilter(UnorderedCollectionString configuration) {
configuration.add(/pathToYourServlet/.*);
}
PS: the configuration page in the regular Tapestry site
(http://tapestry.apache.org/tapestry5/guide/conf.html) is empty.

Re: T5 : Let's write a book !
I'd be happy to help out Toby 2008/8/25 marcelo_Java [EMAIL PROTECTED] I'm want to be part of this, I've use tapestry for over two years now and created many J2EE solutions with it. My most recently battle was when I wanted to create a CMS using a WYSIWYG editor called TinyMCE with tapestry and I was stuck until I discover the outputraw component. Regards, Marcelo Rodrigues Howard Lewis Ship wrote: It is certainly an interesting idea. I think HIbernate follows a similar approach; they have a Wiki (Confluence, perhaps) and they scrape it to get the packaged documentation. We could look into running a more involved Wiki, perhaps from tapestry.formos.com. Confluence would be reasonable, as I can get an open-source project license for any of the Atlassian products. The problem with this is oversight; writing a book in any format consists of a lot of dull work. In an open community its hard to motivate people, without a direct stake, to do that kind of dull work. On Mon, Aug 25, 2008 at 9:03 AM, Alex Kotchnev [EMAIL PROTECTED] wrote: First of all, I apologize for the long post in advance, I couldn't figure out how to make it shorter. I've been thinking about how much I miss the unborn T5 in Action book. I spoke to Howard a while back and he said that it's unlikely that a new revision of the Tapestry In Action (from Manning) would happen : understandably, he has the framework to worry about, not the books, and it's unlikely that he'd have 1 year to take away from work and write a book. Thus, I've been trying to figure out ways to substitute for the missing manuscript. Here are my impressions so far: * The T5 book from PacktPub is a nice intro, but it's out of date and it's kinda shallow * The wiki has some nice content on it, but it's disorganized and a little too random: you may find something useful on a subject, and then, you may not * The project docs are often quite useful and often times quite deep, but they don't have enough examples to put things in context * The tutorials are all focused around getting started, and don't have enough substance * Finally, the example apps (e.g. JumpStart, t5-acegi example, shams, etc) are extremely useful; however, (by design) there's little narrative surrounding them to explain how and why things work the way they do. Thus, the bottom line is that one has to hunt down 5 different resources (possibly more) to pull together a coherent picture , especially when one goes deeper than the getting started stage. Now, I clearly don't know enough about T5 yet to write a book myself (as much as that sounds appealing to the ego) and it's unlikely that I could possibly dedicate the time and effort to do it all. So, I had the idea for a while that it would be extremely cool and useful if a bunch of the people interested in T5 could get together (incl. myself) and write a book on the subject. Tim Sweetser jumped in with the idea on the IRC channel that we could do a collaborative online book : put together a rough outline of the potential content (chapter and section-wise), then let users contribute to the effort by filling in the blanks (with some editorial oversight). So, if something like this were possible, a bunch of people can get their minds together, each one contribute a chapter or two and kick off the effort. This way, each one person can focus on a subset of the problem, describe it in sufficient depth (e.g. research the areas that he/she is unfamiliar with), and not weigh down anyone in particular with an enormous amount of effort (such as writing a whole book). Surveying the landscape, similar things already exist. Tim Sweetser mentioned that Django did something like this. I know that Grails has quite a thorough user manual that covers most of the important areas of the framework. I also remember bumping into the PHP manual where people could comment and add relevant examples and such. So, in conclusion, this is possible, people have definitely done it, and it's HUGE for the community around the project. So, the next question is, how should something like this be done ? * The Wiki seems like a no brainer to start with, add the TOC and then allow people to contribute. The potential problem with it is that code and the examples can easily become stale. I know that the examples of the Grails user manual are somehow compiled and checked that they run before a new version of the manual is published. * Another option seems to be putting a bunch of Docbook files in SVN and collaborating through SVN to move the book forward. The upside of doing something like this is that it gives us an immediate perk of being able to export a printable version of the book. Downside is that contributing to the book is not all that easy (e.g. some DocBook knowledge
Re: T5 : Let's write a book !
This is great, we have at least a bunch of people who would like to contribute. Any comments on the last couple of questions from my post : 2. Is there an existing place where this effort can be channeled better, instead of creating something new ? I still don't know the answer to this question. One option would be to try to enhance the existing docs, but it seems that the two will have a slightly different purpose. The docs try to deliver as much punch as possible within a couple of pages, whereas the book will probably have to be a little bit more explanatory. 3. If this could be a new effort (e.g. a project tapestry-doc, maybe??), what are any additional requirements for doing it (in addition to some of the ones listed above). Would it be an option to have an SVN component in the Tapestry repository, or would this be harder than necessary (e.g. overhead of Tapestry being an apache project) ? Any comments on using Google code for this ( they already have a wiki and an issue tracker for each project) ? 4. If this is to be done, what's the best way of doing it ? I'll research to see if I can find out how Django did their, but general feedback ideas on the technicalities would be very useful. E.g. how do people collaborate best on writing a book ? Is there an existing service that might make this easier Has anyone written a book or collaborated with a couple of other people in writing one (other than Howard :-) ). Do you know personally anyone who has such experience ( I plan to ping Geertjan Wielenga from the NetBeans community to see if he can give me some advice) ? Any ideas of how we can handle the code in the book (to make sure it always works) ? Would the user list be the best place to keep the discussion going or would this be an annoyance to everyone else ? I guess the easiest start would be to post some kind of outline of the book table of contents on the T5 wiki. While we're coming up with that we should probably figure out the answers to the questions above, as I don't think the wiki is the ultimate place to keep this. Cheers, Alex Kotchnev
Re: T5 : Expanding Messages Catalog for localization from arbitrary source
Ok, thanks, I'll try that! I already tried the following in my class that
extends AbstractMessages:
@Inject
private HttpServletRequest request;
@ApplicationState
private User user;
Which didn't work, both were null. But what your saying is that these
objects are not possible to inject in this scope, but RequestGlobals is, so
the following will work?
@Inject
private RequestGlobals requestGlobals

Hi Inge,
glad to have been able to help you!
For your current problem, I can see two immediate solutions.
1. Store your user object as an ASO and inject ApplicationStateManager into
your Messages implementation. Get the user object instance by calling
applicationStateManager.get(UserObject.class).
2. Inject RequestGlobals in your Messages implementation. Then you can get
the request by calling requestGlobals.getHTTPServletRequest().
I hope this helps

Hi, Hannes!
I tried your implementation, and it worked right away, I just returned the
value TESTING TESTING from my DbMessages class that extends Abstract
Messages.
But, what I need is for the valueForKey(String key) method to be aware of
the languageId/customerId of the currently logged in user. In all my other
pages, I get this through injecting the request and getting my user object
from HttpSession. Alternatively this can be moved to an ASO, but I haven't
taken the time to do that yet.
I've tried injecting HttpServletRequest and ApplicationState on all the
classes listed in the implementation from Hannes, but none of them work
(only null values). How can I make information from the current user
session
available to my AbstractMessages implementation?

I tried the route with the Decorator once, and ended up having to write

Your example worked great, i only had to pass some more Services
(AssetSource to get the URLs, my ProjectContextProvider to get the

could return the value for a Message-Key from the bundles, or if not

Hi
I have recently wondered about the same, and have now built something
that after much trial and error now works.
Basically, I have created a Messages implementation that wraps both a
tapestry Messages object and our own database messages. If a message is
not
found in our database, the default Messages object is queried.
To get Tapestry to use my Messages implementation i had to decorate the
ComponentMessagesSource (and ValidationMessagesSource), since it is not
possible to replace the one in Tapestry. I think I read about
decorating
services here:
http://tapestry.apache.org/tapestry5/tapestry-ioc/decorator.html and
on
the mailing list.
My messages source service doesn't implement the
ComponentMessagesSource
interface. I use an interception object for that. Hopefully you can
understand how it works from my example code below:
public class CommonsMessages extends AbstractMessages {
private Messages fallbackMessages;
protected String valueForKey(final key) {
... logic to get key from db, use fallbackMessages as fallback...
}
}
-
public class CommonsMessagesSource {
public Messages getMessages(Locale locale, Messages
fallbackMessages)
{
... code that creates a CommonsMessages object, with
fallbackMessages ...
}
}
// This is the decorating class
public class CommonsComponentMessagesSourceInterceptor implements
ComponentMessagesSource {
private final CommonsMessagesSource service;
private final ComponentMessagesSource delegate;
public CommonsComponentMessagesSourceInterceptor
(CommonsMessagesSource service, ComponentMessagesSource
delegate)
{
this.service = service;
this.delegate = delegate;
}
public Messages getMessages(ComponentModel componentModel, Locale
locale) {
return service.getMessages(locale,
delegate.getMessages(componentModel, locale));
}
// Not sure about how I should handle this one
public void addInvalidationListener(
InvalidationListener invalidationlistener) {
delegate.addInvalidationListener(invalidationlistener);
}
}

[T4.1] Interacting with Tap form from separate widget
Hello, I have a complex JavaScript input-widget, and I want to tie its value into a Tapestry form. I made a @Hidden component, gave it an ID, and used JavaScript to set its value based on my widget. My tapestry listener kept getting the string true, regardless of the value being set to the @Hidden, presumably because I was not prepending the value with S. Is there a clean way to cooperate with a Tapestry form, i.e. through an API? Was looking for something in the dojo-based library Tapestry uses, something like tapestry.html.setStringValue(), but couldn't find anything. I'm fine resorting to cycle.getParameter(..), but wanted to check. Thanks, Jim - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
