Re: Apache FOP integration

BTW Itext is no more open source, right?

Hello everybody

Thank you all for your responses. Very useful to learn various libraries
are being used in Tapestry apps. iText, JasperReport, PDFBox, and FOP.

We'll go with Apache FOP in our project as it turns out we can re-use some
FOP stylesheets from another project.

A Tapestry FOP module would be useful for configuring FOP in a Tapestry
manner. Likewise, it would include a service that would hold the FopFactory
instance which (according to the FOP docs) is supposed to be reused if one
plans to render multiple documents during a JVM's lifetime.

As Ilya described, a Tapestry FOP module is, however, not necessary. One
can just read a config file and configure FOP programmatically.

Again, thank you all for your thoughts. Have a nice weekend.

Cheers,

Volker

This is the entire code responsible for producing PDF:

 fopFactory = FopFactory.newInstance();

fopFactory.setUserConfig(fopConfigResource.toExternalForm());
fopFactory.getFontManager().setFontBaseURL(fontsDirectoryResource.toExternalForm());
}

// use Saxon instead of Xalan
System.setProperty("javax.xml.transform.TransformerFactory",
"net.sf.saxon.TransformerFactoryImpl");
TransformerFactory transformerFactory = 
TransformerFactory.newInstance();


// register Saxon extension functions
TransformerFactoryImpl saxonFactory = (TransformerFactoryImpl)
transformerFactory;
Configuration configuration = saxonFactory.getConfiguration();
extensionFunctions.getAvailableFunctions(activeLocale).forEach(configuration::registerExtensionFunction); 



// initialize transformer
Source template = new StreamSource(templateStream);
Transformer transformer = transformerFactory.newTransformer(template);

// 2) serialize object to xml
File tmpFile = File.createTempFile("fop", ".xml");
FileOutputStream marshallerOutputStream = new FileOutputStream(tmpFile);
JAXBContext jaxbContext = JAXBContext.newInstance(object.getClass());
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(object, marshallerOutputStream);
marshallerOutputStream.close();
logger.info("marshaller result: {}, {} bytes", tmpFile, 
tmpFile.length());


// 3) perform transformation
FileInputStream fopInputStream = new FileInputStream(tmpFile);
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
foUserAgent.setProducer("producer name");
foUserAgent.setCreationDate(new Date());
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, 
outputStream);

Source xmlSource = new StreamSource(fopInputStream);
Result pdfResult = new SAXResult(fop.getDefaultHandler());
transformer.transform(xmlSource, pdfResult);
fopInputStream.close();
if (!tmpFile.delete())
 logger.warn("unable to remove temporary file {}", tmpFile);


There's basically nothing else. After processing, *outputStream* will
contain your PDF. Note that my example includes:

    - using custom fonts (you probably don't need this);
    - using custom extension functions for Saxon (you probably don't 
need

    this either).

Otherwise it's pretty much straightforward.

OT: servlet container and update SSL certificate without reload

[Ivano Luberti]

Hello, searching for a solution about how to update SSL certificates
(keystore) without restarting the servlet container.

Looking at the Tomcat docs it seems not possible.

Googling I have found some solution that propose to restart only the ssl
connector,but before starting to try something not really tested I
wanted to see if there is someone outh there that has found a solution:
either switching to another servlet container or implementing something
or using some third party tool.

TIA for any suggestion.

Hi Mukesh, I have put some instructions on how to build a service to
output a PDF in this file

https://www.dropbox.com/s/bnpq2tq58drbdn0/Tapestry4Pdf.zip?dl=0

I have extrapolated from my code, so is not working code, only
instructions of necessary steps: service creation, configuration,
building link to invoke it.

Hope it helps.

Re: Embeding PDF document in Tapestry4 page

[Ivano Luberti]

Hi Mukesh, Tapestry 4 is not suppported anymore but I personally still
have to manage some applications written with that version and in one of
those I wrote a service that outputs a PDF.

Basically you have to write a service and set the response type to
application/pdf

Ti make the user abel to download the PDF you have to build a link with
paramters, the link invokes the service and pass the params to it, the
service builds the PDF and put it in the response. The effect is to open
a new tab in the client browser with the PDF displayed.

Now I'm pretty busy but I can send you some source code later.

(solved ?) tapestry 4.1.6 and pergmen question

[Ivano Luberti]

I write this so it goes on web archives and maybe (even though is not
probabile) one day someone will find it useful.

The solution is to avoid this

https://wiki.apache.org/tapestry/EasyBrowserRedirection

never raise that exception.
Instead use

PageRedirectException

in case you want to pass parameters to the page put them in the session
and remove them in rendering phase of the page you are redirecting to

finally be sure PageRedirectException also in the the page you are
redirecting to because it will not be trapped an Tapestry Exception page
will be showed.



---

It seems I have found the glitch.
Following this suggestion

https://wiki.apache.org/tapestry/EasyBrowserRedirection

I had implented redirection in a pageBeginRender method (I'm talking
about T 4.1.6, sorry about that)

Now it seems that when the excpetion is raised PermGen occupation is
increased.

It seems there is a difference with this regard raising the exception in
a listener instead that in pageBeginrender.

Anyone feels its memory activated on this?

Re: tapestry 4.1.6 and pergmen question

[Ivano Luberti]

Thanks Kalle, I know the links you suggest, but I was exlcuding my code
because it has not been chaned much from the one on the old server

Anyway I will keep on investigating, I have no other choice.

Thanks anyway

Re: tapestry 4.1.6 and pergmen question

[Ivano Luberti]

Kalle, Chris, thanks for your answers.
Unfortunately the problem is not related to webapp reloading even
restarting the Tomcat service leads to out of PermGen in a few days,
PermGen itself is quite large and I already use UseConcMarkSweepGC. Down
here you can read the java settings :


-Djava.awt.headless=true -Dfile.encoding=ISO-8859-1 -Xms512m -Xmx2048m
-XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=/var/log/tomcat6 -XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled


The cause of the space consumption seems to be the presence of a lot of
classes of this type

org.apache.tapestry.enhance.ClassFactoryClassLoader

It seems that the more request the application serves the more PermGen 
increases and that's led me to think that the page pool is never cleaned up or 
at least not well cleanedup.

Hey Tony, if you don't mind, can you send me all the configuration
options of Java and Tomcat you are using? So tomcat6.conf and server.xml
files?

No one else on the list can share its thoughts?

I have only  -Xmx2g

I use 

-XX:+UseConcMarkSweepGC

but not 

-XX:+UseParNewGC


but this last one doesn't seem to have an influence on PermGen, does it?

tapestry 4.1.6 and pergmen question

[Ivano Luberti]

I know I know, please don't shoot the pianist.
I have an old application written using Tapestry 4.1.6 and I can't get
the budget to rewrite in Tapestry 5.
(BTW I have already and succesfully used Tapestry 5, so I know what I'm
loosing here)
The application run without issues for years on a CentOS+Tomcat 5.5+Java
6 combination but recently  I had to move it to a new server where I
have CentOS+Tomcat 6+Java 6.

Suddenly the application started to quickly run out of memory with the
dreadful PermGen Out Of Meory Error.

I got an heap dump  in an hprof file and found that there thousands
instances of

org.apache.tapestry.enhance.ClassFactoryClassLoader

still alive

Does anyone have any clue of permanent generation memory issues with
Tapestry 4 and Tomcat 6 ?

TIA

strange issue with Eclipse + Tomcat (solved)

[Ivano Luberti]

Today I got lost for a few hours trying to solve the following issue.
Since I couldn't find anything googling I thought it worth to spend a
few minutes to write it on the list.

I use Tomcat+Eclipse on a Windows box to develop
To achieve auto-reloading I set the Serve modules without publishing
option while developing.

Today I deployed my application on a customer server and after loading
the first page correctly I kept getting the following exception on the
second one

org.apache.tapestry5.ioc.internal.OperationException
Embedded component(s) barCodeForm are defined within component class
it.archicoop.met.obliterazione.pages.BarCode (or a super-class of
BarCode), but are not present in the component template (null).

So clearly Tapestry was not able to load the tml file: but why?
Well of course there was a mistake by me:
I have

BarCode.java

but

Barcode.tml

what of course was misleding me was the fact that I had been able to
develop without issues but when deploying  I hit this kind of issue.
Finally I discovered that also on the dev (windows ) machine, removing
the flag for the Serve modules without publishing option causes the issue.

Or better said using Serve modules without publishing option Tomcat
seems to be not case sensitive on file names.

Hope this message can save time to someone someday

Re: tapestry and jquery

[Ivano Luberti]

Thanks for all the comments, here is a cumulative feedback:

I have tried the tapesrty5jquery dialog demo using 3.3.4 and 3.3.7
version in the Tapestry5 tutorial using Tapestry 5.3.7
but didn't work. Asked on their google group (thati moderated) and saw
there are no post since september 2013.
So I was worried about the kind of support I can get: it was not a
complaint, just trying to understand where they are.
Activity on GitHub  seems to keep up. But no feedback neither on twitter.

I have of course googled for help and specifically searched nabble but
(not a surprise) there is almost nothing on this list.

I have to start from scratch : better said I have already implented the
app with no client side feature. And now I want to add javascript/ajax.
Later I will pass it to a colleague for CSS customization.

The application is quite simple and I'm using it as a learning tool.

So maybe porting to 5.4 worths it .

And I wiill use suggestion by Francois to post my actual issue, even
though also the issue tracker doesn't seem to be updated since september
2014

 Maybe someone can shed some light on it now.

 I ask questions and get no answer sometimes - could be the way I ask, not
 tapestry itself or waste of time.

 I've used both 5.3 tapestry-jquery really well, and tapestry-5.4-beta22.

 Have you already got a HTML/css/jquery prototype ready or are you starting
 from scratch?

well in my case authentication and authorization is verified using

 that works as expected

 I wanted to perform some cleanup when calling a logout link: the action

 You can (and should) @Inject Request. There's absolutely no reason in
 the last 5 years to use RequestGlobals to get the request object. You
 can also @Inject HttpServletRequest and HttpServletResponse directly
 if needed.

 @Inject
 private Request request;

 ...

 Session session = request.getSession(false);
 if (session != null) {
 session.invalidate();
 }


I have done also this but to no avail.

package it.archicoop.met.obliterazione.beans;

import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;


public class User implements HttpSessionListener {
   
public  User() {
}
   
public void sessionCreated(HttpSessionEvent se) {
   
System.out.println(session started +se.getSession().getId());
   
}


public void sessionDestroyed(HttpSessionEvent se) {

System.out.println(session ended +se.getSession().getId());

}
}


Then I have

package it.archicoop.met.obliterazione.pages;
public class Index extends BasePage
{

and

package it.archicoop.met.obliterazione.pages;
public class BarCode extends BasePage
{


Logout link is implemented using  a component

package it.archicoop.met.obliterazione.components;

import it.archicoop.met.obliterazione.pages.Index;

import org.apache.tapestry5.ioc.annotations.Inject;
import org.apache.tapestry5.services.Request;
import org.apache.tapestry5.services.Session;


public class Logout
{
@Inject
private Request request;
   
public Object onActionFromLink() {
   
 
Session session = request.getSession(false);
if (session != null) {
session.invalidate();
}
   
return Index.class;
 
}
   
}


public Object onActionFromLink() {
   
 
Session session = request.getSession(false);
if (session != null) {
session.invalidate();
}
   
   
return Index.class;
 
}


What happens


startup app

User constuctor called

it.archicoop.met.obliterazione.beans.User@2a801059

When I call the Index page in the browser  onPrepare is called

session created

it.archicoop.met.obliterazione.beans.User@2a801059

user field is null so constructor is called explicitly:

it.archicoop.met.obliterazione.beans.User@50862b70

login form submission

it.archicoop.met.obliterazione.beans.User@50862b70

Logout link

BarCode is the container of the Logout component

and user is null (WTF!?)

after session.invalidate is called

Session Destroyed

it.archicoop.met.obliterazione.beans.User@2a801059

Since I redirect to Index, again

onPrepare

user is initially

it.archicoop.met.obliterazione.beans.User@50862b70

then

user null

then recreated

it.archicoop.met.obliterazione.beans.User@4c057cc6

SessionCreated called

it.archicoop.met.obliterazione.beans.User@2a801059


So it seems that the field of type User is not persisted between
different pages.
And there is no relation between the user instances managed by the
servlet containt via SessionListener interface and the one in the pages

As I sadi before: there are other ways to centrailize session boundign
and unbounding but I wanted to know if in Tapestry I can use the
HTTPSessionListener inteface for object persisted in the session

 Hi!

 What's your onPrepare() method? You didn't post it here. By the way,
 you could print a stack trace inside the User constructor to know
 exactly which method is instantiating it.


Here is the code: is not onPrepare but setupRender , sorry, I had
changed it from onPrepare but the result has not changed, anyway


@Log
public void setupRender(){
   
   
try {
   
Loginform lf=
user.getWsclient().getLoginForm(requestGlobal.getHTTPServletRequest().getRemoteAddr());
   
monumenti=lf.getMonumenti();
   
postazioni=lf.getPostazioni();
   
idMonumentoSelezionato=lf.getIdMonumentoSelezionato();
   
   
user.setIp(requestGlobal.getHTTPServletRequest().getRemoteAddr());
   
} catch (Exception e) {
   
logger.debug(e.getMessage());
}

   
}


Here are the stack traces produced by the constuctor calls and
sessionCreated and session destroyed methods
You can see that

1) an instance A is created when tomcat starts up

2) instance A is bounded to the session when first page is visited

3) when first page is visited also instance B is created but not bound
to any session

4) on logout instance A id unbound from session

5) on redirection to Index instance B is discarded and instance C is
created but not attached to the session

So B is created in the first page but not bound to the session while
some way is visible across pages
While A is created at server start-up (why?) but is not visible in the page.
If from web.xml  I remove

listener
   
listener-classit.archicoop.met.obliterazione.beans.User/listener-class
/listener

of course A is not created anymore but neither are called sessionCreated
and sessionDestroy
While B keep on behaving as described

When I start the application an instance is created and printing a stack
trace produces:

 If you declare your User class like this, for the listening itself,
 the servlet container will create a single User instance and invoke
 its methods. This is completely unrelated to Tapestry's @SessionState.
 Why are you doing that? Using the same class for this listener *and*
 as an @SessionState field makes no sense at all, at least at first.

 Shouldn't your User class implement HttpSessionBindingListener instead?

session invalidate in tapestry

[Ivano Luberti]

Hi all, I have a question about session handling in Tapestry5.
I have a

@SessionState
protected User user;

that works as expected

I wanted to perform some cleanup when calling a logout link: the action
link listener is made as this:

public Object onActionFromLink() {
   
 
requestGlobals.getHTTPServletRequest().getSession().invalidate();
   
   
return Index.class;
 
}

I don't know if this is important (I guess not) but the method is in a
component and not direclty in a page (so that I can render the link only
in protected pages )

To centralize the cleanup that could happen both on logout action and on
session timeout I have implemented the User with the  HttpSessionListener.

The problem is that after the invalidate() call the method

public void sessionDestroyed(HttpSessionEvent se) {

is called as intended but the User object is empty as it was just
instantiated and in fact debugging I can see that is a different
instance from the one created when the session was started.

I can certainly find other ways (a RequestFilter?) but I would like to
understand what is going on.

TIA

default locale question

[Ivano Luberti]

Hi all, a quick question on locales management
I want italian as default locale for my application

I have found this in the configuration section:

 tapestry.supported-locales

 A comma-separated list of supported locales. Incoming requests as
 narrowed to one of these locales, based on closest match. If no
 match can be found, the first locale in the list is treated as the
 default.

So I have added in AppModule

configuration.add(SymbolConstants.SUPPORTED_LOCALES, it,en);

but calling

http://localhost:8080/tutorial1/

I get English.

Calling

http://localhost:8080/tutorial1/it

I get Italian

Calling

 Hi, I'm trying to figure out how to add a PropertyEditBlock to have drop
 down lists fed by a List type.

 What do you mean by a List type? java.util.ListSomeClass?


Yes I hoped it was clear from the subect

 I have found this example:

 http://wiki.apache.org/tapestry/Tapestry5HowToCreateAPropertyEditBlock

 but I see links to code are not working anymore: can someone tell me if
 that is the right approach before I try it out?

 Thank heavens the link to GenericSelectModel is broken, as it was a
 really bad idea.

 I prefer http://tapestry.apache.org/beaneditform-guide.html, which is
 a better description than the page you mentioned above.


Yes I saw that page, of course but to me, for a newbie it lacks
indications on how to get together the select model with the bean model.
In real world scenarios populating a drop down list from an enum is far
more rare than populating from a Map or a List dynamically generated
from a data source (DB or web service as in my case).

So for a newbie to have a BeanEditForm ready to use with this respect
could be quite important. BeanEditForm in fact is documented in the
Getting Started guide since is correctly deemed as a Basic funcionality.

Another thing is not mentioned in the BeanEditForm guide is the coercion
of Map to SelectModel: I guess  this means that if my data provider give
me Maps I can override the property editor and I'm done.

One more observation on the guide:  BeanModelSource.create is deprecated
:-) : the guide is outdated.

However even turning to BeanModelSource.createEditModel doesn't work for
me because my bean to be created needs the IP address of the client.  I
will give a try later when I will implement other forms...

I fear I will have to use a normal Form component.



 http://wiki.apache.org/tapestry/Tapestry5HowToCreateAPropertyEditBlock
 has something I don't like at all: creating a class (DropDownList)
 just for being used in BeanModel-based components (BeanEditForm,
 BeanEditor, Grid, BeanDisplay), not being the type of the field in
 your domain or entity class, which would be String, int, an enum, some
 other custom class, etc. Instead, I prefer to keep the field in its
 right type, which is the type of the options you want to provide.

 The implementation varies a bit depending on what the type of the
 selection is. If it's an enum or some custom class, you can follow the
 http://wiki.apache.org/tapestry/Tapestry5HowToCreateAPropertyEditBlock
 example replacing DropDownList by your class and writing an
 appropriate ValueEncoder for it. You don't need to subclass
 AbstractModel yourself: just use the SelectModelFactory service
 methods instead.


I see your point but I'm not sure I'm totally with you on this.
Of course you are more experienced than me in what the reasons are
beyond tpaestry choices, so I feel quite uncomfortable arguing your
arguments but I try it anyway. I hope you will keep on being patient
answering even if I totally miss the point.

In real world application we will get object from the DB to populate the
drop down list and when an item is selected we will have always an id in
our page class to make it aware what item has been selected .
So there will be always the need to extract from the object a mnemonic
identifier to be showed in the selection for uman reading and an
identifier to indicate the selection to the page.
I believe this is why you need a ValueEncoder, right?





 If it's something like, for example, an int field with values from 0
 to 10, the only difference would be creating an annotation (@Rating,
 for example), then implementing a DataTypeAnalyzer which retuns rate
 when the field has @Rating and contribute your newly-written
 RatingDataTypeAnalyzer to the DataTypeAnalyzer service. The rest stays
 the same.

 It seems to me that using List for drop down list is quite mandatory to
 manage forms in real world applications.

 Yeah, but the way you describe this is too vague to have a single good
 implementation for all cases.

 BTW: if it is the right approach why not moving that example to official
 documentation?

 Because the right approach for adding BeanModel edition and viewing
 blocks is already at
 http://tapestry.apache.org/beaneditform-guide.html, Adding New
 Property Editors section. ;)

 Yes. Deploy as exploded and remember to turn off container auto-reloading.

 Of course this goes against all the maven stuff that seems to be used by

Hi Christian, it seems to work: I used the tutorial T5 project created

then modified on the fly the index.java file and modification have been

 So if instead of the maven project layout I use the classic WTP project
 layout that has a
 WebContent folder which includes WEB-INF/lib and WEB-INF/classes and if
 properly configured builds classes from my source folder into
 WEB-INF/classes I would get LCR working. Is this correct?

 Yes. Deploy as exploded and remember to turn off container
 auto-reloading.
 Of course this goes against all the maven stuff that seems to be used by
 the vast majority of T5 devs.

 Not only T5 but vast majority of Java devs.

Hi Muhammad, I have used the acronym found in Tapestry docs: Live Class

And I forget to say I want to use Tomcat (this is why I mentioned the
Sysdeo plugin)

Thanks Kalle, maybe I'm starting to figuring it out.
So the devloader enables the container to load classes from paths
aoutside WEB-INF/lib and WEB-INF/classes , right?

So if instead of the maven project layout I use the classic WTP project
layout that has a
WebContent folder which includes WEB-INF/lib and WEB-INF/classes and if
properly configured builds classes from my source folder into
WEB-INF/classes I would get LCR working. Is this correct?

Re: [OT] encoding of properties files

[Ivano Luberti]

Thanks to Hugo and Jim for their answers.
I was aware of the encoding of files that Java uses for properties files
and so my editor (actually the Eclipse default properties file editor)
is set properly to ISO-8859-1 .

However my deve environment is on a Windows machine and when I test my
web site running

  System.out.println(  Default Charset= + Charset.defaultCharset()+;+
file.encoding= +
System.getProperty(file.encoding)+;+
Default Charset= + Charset.defaultCharset()+;+
Default Charset in Use= + getDefaultCharSet()));


I get

Default Charset=windows-1252;file.encoding=Cp1252;Default
Charset=windows-1252;Default Charset in Use=Cp1252

and still properties files content is dipslayed correctly
While on the server (an Ubuntu box) where pages are displayed
incorrectly the same check shows:

Default Charset=US-ASCII;file.encoding=ANSI_X3.4-1968;Default
Charset=US-ASCII;Default Charset in Use=ASCII

 Tapestry does have the advantage of clean HTML files as templates.
 Just use invisible instrumentation always. Tapestry just doesn't force

Maybe, but as you try to write java code as clean as possible, I cannot
see why you shouldn't do the same thing with your html code.
Even because usually you want to show your html static pages to the
customer before starting to implement something else.

 Because if you aren't working with a designer writing:

 ${user.firstName}

 is much faster than writing:

 span t:type=output t:id=firstNameOutput
 t:value=user.firstNameFirst Name Here/span

Re: Tapestry 4.1 injecting the wrong application state object

[Ivano Luberti]

In our case we were lucky enough that we can ask user to change language
only on a given page.
So the solution we adopted was to duplicate that page and to have
listeners for changing language that where pointing to the other page.
This because the language is changed only when page is rendered:

http://tapestry.apache.org/tapestry4.1/usersguide/localization.html

So you have pageA with a link changeLanguageLink pointing to listener

public pageB changeLanguage(String locale){
this.getRequestCycle().getEngine().setLocale(new Locale(locale));
return getPageB();
};

Conversely you have a similar link in pageB returning pageA.

Hope this helps

 Well, the idea in Tapestry has ever been that the locale for a page is
 fixed, once determined, and it's hard to say what the effect of your

 I don't currently remember where in Tapestry 4.1 the determination of
 client locale is made; when I have some time, I'll try and look in the
 code and see what turns up.

 Hi Howard,

 Further to my last message, I just discovered that I was making a faulty
 assumption. When the pages are checked out of the pool, the engine locale is
 used to build the page key, but when they are released to the pool, the
 *page* locale is used! So overriding getLocale() on the page is indeed
 causing problems.

 Can you tell me what the correct way of doing this is? Apart from wanting to
 give the users the ability to configure their language in their user
 settings in our application, it is also problematic that the locale that the
 browser provides is often missing the country, and Java often does not use
 correct date, time and number formats if the locale does not include the
 country.

 And do you have any idea if this could also the root cause of my original
 problem? I don't really see how, since all this means as far as I can tell
 is that Tapestry will needlessly instantiate pages, but I still don't see
 how a page which still contains values from one session can end up on
 another session.

 Kind regards,

 I'd look along those lines.

 Anyone else have any idea?

 In short: my Page objects occasionally get the wrong application state
 object injected by Tapestry 4.1!

 I've been looking into it, but it's very hard to see what's going on with
 all the synthetic classes created by Hivemind. But one clue I got by
 making
 a heap dump and analysing it: all application state objects (of closed
 sessions) were still in memory, with references from Page classes in a
 TapestryKeyedObjectPool!

 I'm pretty sure the Page properties are supposed to be cleaned out at the
 end of a request cycle, when the page is returned to the pool, but
 apparently for some reason that is not happening! Is this a familiar
 problem
 to anyone?

 Kind regards,
 Pepijn Schmitz

 Hi,

 Thanks! But I don't think that's it. We're already using HTTPS, but
 also
 that would not explain how the correct application state object can be
 on
 the HttpSession, even though Tapestry injected the wrong one...

 We are using Apache 2 using mod_proxy as a front-end though. Apache
 takes
 care of the SSL and forwards the requests to Glassfish over HTTP. I'll
 look
 into the possibility that something is going wrong there, although it
 seems
 unlikely due to the above reason...

 Cheers,

 So initial suspect was the squid proxy configuration of our ISP. The

 that

 acceptable
 even with HTTPS we just left everything as is.

 Hence I'd suggest temporarily requiring HTTPS for the whole site and

I'm sorry but I strongly disagree: I have never seen a support service
as efficient as this mailing list.
And for free.

 Exactly! I'm often disappointed with the level of help offered here,
 and maybe that's because the mailing list is too much a community
 where people try to stay connected continuously and not enough a
 question/answer type discussion.

Fwd: Re: JSF vs Tapestry

[Ivano Luberti]

I forward to the list what a jsf developer has written to me: I'm
working with him on a project where he has to develop the web
application and I'm working on a web service consumed by his web
application.

I had forwarded to him a message by Thiago that was trying to point out
differences between T5 and JSF.
The interesting thing he has to say is about facelets as a way to use
standard XHTML templates inside JSF.
Also the difficulty to use together different component sets is
interesting: reminds me of the issue with different JavaScript
components in T5.

But what really surprises me is the similarity he found between struts
and JSF


 Messaggio originale 

Hi Ivano, 

We do indeed use JSF for our web development and more specifically we
use Icefaces which is a set of AJAX enabled components and AJAX push
framework which sits on top of JSF. We chose to use JSF because it
wasn't too dissimilar from Struts which we were using before. Generally
we find it very good although it does have some shortcomings but they
don't tend to get in the way too much. We are using JSF 1.2 but JSF 2.0
is now available and adds support for some of the things on your list
such as, you can now use annotations for lots of things you use to have
to use XML for, there is also the addition of page level scope as per
the tapestry idea. One point the tapestry guy is wrong about though is
that with JSF you don't have to use JSP, that is only one option. We use
facelets which is now part of the JSF 2.0 spec so if you use that you
code directly in XHTML using the relevant faces tags, thus the problems
that came from using JSP as a display layer disappear.

With JSF you get a choice of which component set you want to use, or I
believe you can use multiple but then configuration becomes more
challenging. We looked at a number including Richfaces and Woodstock and
decided that Icefaces offered the best set of components. All three of
those are open source though so are completely free to use, although
support is available too.

Unfortunately I don't know a great deal about tapestry so I can't really
say how it compares to JSF, I think you'd have to evaluate them both and
decide which one is easier for you to work with based on your previous
experience. 

Hope that helps,
Darren

Re: [Tapestry Central] Tapestry Frequently Asked Questions

[Ivano Luberti]

I disagree about the FAQ as the better documentation for OS projects.
Yes they are necessary, but user guides have to be the first step to get
to know a new system.
With user guide I mean a step by step guide that teaches to the newbie

1) how to setup environment and start developing simple things (hello
world and little more)

2) how to integrate common third party libraries (ORM, logging) or
products (Javascript libraries)

3) how to realize various type of applications with the framework (web
applications, web service, CRUD operations)

I think that 80% of development tasks are common to all web projects

FAQs are useful for common problems, not for common tasks.

Just my 2 cents


Il 18/08/2010 2.33, Howard ha scritto:
 I'm taking some time to work on the Tapestry documentation ... starting
 with the FAQ. It's great fun, though this could get to be quite large.
 I'm just spewing out content right now, over time we'll clean it up,
 reorganize it, and add further hyperlinks and annotations.
 In fact, as I'm working on the FAQ, I'm thinking this might be the best
 way to document open source projects in general. User's guides and
 reference documents are rarely read, everyone just Google's their
 question, so put those questions in their most findable format. Also,
 it's hard to write a consistent user guide start to finish ... but more
 reasonable to document one tidbit at a time.
 Also, I'm reminded of The Little Schemer, a book that teaches the
 entire Scheme language (a Lisp variant) via a series of questions of
 ever broadening scope.
 Feel free to suggest additional FAQ topics on the Tapestry Users
 mailing list.

Re: How do I set up logging with Tapestry 5 and Tomcat?

[Ivano Luberti]

But if I deploy on a server I cannot control how can I tune my logging?

Il 14/04/2010 23.06, Tim Koop ha scritto:
 To answer my own question, the answer is this:

 You need a log4j.properties file in $CATALINA_HOME/lib, as this page
 describes:

 http://tomcat.apache.org/tomcat-6.0-doc/logging.html

 As soon as that file was there, my own log4j.properties in my classes
 folder started to be used.  Just a guess, but I guess that the missing
 file in Tomcat's directory caused an irrecoverable error with log4j (I
 did have a log4j error in the Tomcat startup script), so nothing else
 worked after that.

 But now it all works fine.

OT: help for development on Windows Mobile

[Ivano Luberti]

Hello I'm developing a web intreface for Windows Mobile for an intranet
application.
It seems that buttons on web pages are not sensitive as buttons in forms
developed with windows native softwares.
It seems that user are always stuck to use the pen or nails insted of
the thumb.
But, for example, controls on the calculator application respond well to
the thumb or index touch.

Anyone hear can point me to some useful resource ?

Re: Check this out

[Ivano Luberti]

Moreover is not the first time that an unknown member of the mailing
list (ie a member that has never written before on the list)  steps in
the mailing list pointing readers to some link where Tapestry is bashed
for some reason and then use this to start a flame or at least a boring
and pointless discussion.
I'm relatively new to Tapesty but when I have seen the post I just
thought : Oh no, here we are again!

 Hi Guys,

 Hi again . . .

 Bumped into this post at
 http://www.theserverside.com/news/thread.tss?thread_id=59510#332651
 and was wondering the validity of the poster's comments. Is this not
 a bad press for Tapestry?

 It's not bad press because:
 * the post is not about Tapestry.
 * the poster doesn't say a word about Tapestry.
 * the only thing said about Tapestry was in the comments, written by
 some person that bashes Tapestry and says lies about it all the time
 at TheServerSide.
 * comments are not press, as far as I know.

 I guess these are the reasons Ulrich called you a troll. At least
 they're the one that makes me think you're a troll.

Re: [Tapestry Central] Live reloading of Tapestry services?

[Ivano Luberti]

Do you work in Italy like me?
It seems to me you made a remark typical of italian work environments.
Not sure if this is true abroad.

Massimo Lusetti ha scritto:

 Didn't want to come to a discussion on this point, I just want to be
 on the pragmatic side.

 In a lot of real situation the decision to write tests and do what a
 good developer should do when producing code is not demanded to the
 developer itself. This is true in a lot of realities (almost all) i
 worked with, so having a tool that let you be agile even when you
 cannot act like an agile developer is a big win for everyone.

T4 receiving calls from external web site

[Ivano Luberti]

Another issue about T4
The web site I'm developing must accept requests from an external web site.
It is a payment gateway system (PGS) to whom I redirect the user and
after payment has been (successfully or not) completed the pgs redirect
the user browser to an appropriate link of my web site.
When I configure the URLs in the backoffice of the PGS it accepts only
strings of the form:

http://servername/appname/pagename

I cannot put something like:

http://servername/appname?page=RispKoservice=page

as it woul be necessary, because must attach its own parameters to the
URL and doesn't accept the ? in the URL

I have seen two possibilities to work around this:

Configuring Friendly URL in Tapestry 4: but for what I read from the
docs enabling friendly URLs disable ugly ones and the PGS will attach a
?par1=valuepar2=value to the URL

Deployng a servlet inside my application and provide its URL to the PGS.
But here comes the problem to render the appropriate page and this would
mean to access T4 infrastructure from the servlet and I don't have a
clue about how to do it : may I extend a servlet to be a base page ?
I guess I could use JSPs to render content but really I would like to
avoid that.

Can someone point me to a viable alternative to the above solutions ?

Good to know!
I was misleaded by the first sentence in the warning at

http://tapestry.apache.org/tapestry4.1/usersguide/friendly-urls.html

and I didn't want to make all the configuration only to know that it
wouldn't work

Andreas Andreou ha scritto:
 just enable friendly url -
 then
 http://servername/appname?page=RispKoservice=page
 will become
 http://servername/RispKo.html

 So, if the PGS requests http://servername/RispKo.html?par1=valuepar2=value
 you can get those values as normal (i.e. cycle.getParameter())

 So you'll render a form (no need to use the Form component for this)

 form action=http://www.example.com/; id=myForm method=post
 input type=hidden name=someParameter value=someValue/
 /form


 If you want to submit the form automatically without having your user
 click anything, hide the form with CSS and use a script similar to
 this at the bottom of your page:

 ...
 ...
  script
   document.getElementById(myForm).submit();
  /script

Re: T4: forward browser to an external web site

[Ivano Luberti]

I know, but a was hoping for some kind of forward to external web site
mechanism.
It shouldn't be impossible to build something like that using HttpClient
or some similar package

Martin Strand ha scritto:
 This has nothing to do with Tapestry, it's how the HTTP protocol works.
 There's just no response you can send which tells the client to POST
 data to another URL. Instead you send a short program which performs
 the POST and hope your client executes that program - that's the
 script solution.

 public ILink formSubmitListener()
 {
   // Do work
   // ...

   return new StaticLink(http://www.example.com/;);
 }

Re: T4: forward browser to an external web site

[Ivano Luberti]

Thanks Martin: it worked.
But what I could do in case I had to submit a form accepting only POST 
method in the form?

 I will try that: for whatever reason I was convinced that I had to

 But checking twice the docs of the web site I have to forward to, I see
 I can use a link.
 Thanks for now

T4 (solution) : calling a page with an ILink

[Ivano Luberti]

Probably not many are interested because it is a T4  problem, but who knows?

Some days ago I have asked about how in T4 redirect the browser to an
external web site after submitting to a listener in a page.
Martin Strand provided me a solution using an ILink.

However that led me to another problem because in my pages I was
handling exceptions returning to a specific Error Page.

So I had a listener that had to return an ILink when all was working as
expected and and an IPage in case of message error to be displayed.

I have found a way to get the link to the page here:

http://wiki.apache.org/tapestry/EasyBrowserRedirection

and hence to redirect to my error page I have used this:

ILink
link=this.getRequestCycle().getEngine().getInfrastructure().getLinkFactory().constructLink(
TapestryRedirectException.getPageService(),false,
   
TapestryRedirectException.getLinkParams(MyPageClassName),false);


  
Since I had to ad some parameters to the page I didn't return directly
the link but I build a new one and I returned that:

return new StaticLink(link.getURL()+par1=value1par2=value2);

To read those parameters in the page java class I have added to the page
declaration the impementation of PageBeginRenderListener interface and
then I have implemented its pageBeginRender method as follows:

public void pageBeginRender(PageEvent event) {
   
   String parameter1= this.getRequestCycle().getParameter(par1),
   String parameter2= this.getRequestCycle().getParameter(par2),
  
}

Hope someone can find this helpful.

Thanks again to the list for all the help it provides.

Re: New Tapestry Website - http://www.seesaw.com/

 Yes IE6 is a pain - it is only 6% of the traffic we are seeing (on the

 We choose tapestry for a whole range of reasons big ones were
 - Components - the side is heavily component based and we re-use elements
 across pages
 - AJAX - we use zones quite a lot and tapestry makes it really easy
 - Development behaviour - it is easy to develop - fewer application
 restarts

 Hi Ben,

 What motivated you to use Tapestry? obviously this is a great choice of
 course!


 As a side note: IE 6 is a malware software developers dream come true, it
 has to be the worst browser since Netscape 4, it has two critical flaws:
 1. A core design flaw in the zone-based security framework that is
 un-patchable, a vulnerability allowing remote execution via Active X, you
 enable any active X control, then you are susceptible, and
 2. Incomplete Support for AJAX which requires active X enabled

 So its probably a wise decision to not support it.

 regards,
 Peter

[T416] Javascript and html templates questions

[Ivano Luberti]

Hi all.

I'm trying to use javascript with Tapestry 4.1.6 and I'm stumbling at
the very first steps.

First of all I see that whenever a form component is specified in the
template Tapestry put a script at the end of the generated html that set
the focus on the first control of the form. If I try to put my specific
function to give focus to a control of my choice, the automatically
generated script is put as the last statement hence overruling my script.

Secondly (I need a log introduction) I have used the example given in

http://tapestry.apache.org/tapestry4.1/components/general/script.html

to give focus to a control of my choice, but it fails: the problem is
that when executed

function setFocus() {
  var inputField = document.barCodeForm_0.barCode;

  if (inputField.type != hidden) {
  if (inputField.disabled != true) {
  inputField.focus();
  }
  } else {
 window.alert('InputFocus.script cannot set focus on a hidden field');
  }
}

I debugged it using firebug and it seems then document.barCodeForm_0 is
undefined.
Actually looking at the generated html , barCodeForm_0 is there.
But the html as a whole is a little weird. I attach it to the end of
this message: the point is that html tag is closed and reopened several
times.  I'm not enough javascript expert to understand if this is could
cause my problem but looks anyeay bad to me.
Here is my question: I had read that T416 templates have to be well
formed HTML files but looking at the Tapestry Bench application I see
that html templates don't include html, head and body tags.
May I include them ?

Re: T4: including javascript in a component

[Ivano Luberti]

Thanks Andreas , the problem is that everything works until I insert the
javascript.
In fact the exception is thrown inside the Script implementation. Down
here you'll find the init part of the srtack trace.
I was wondering if not using the @Body in the component html template is
correct, given the fact that it is used in the html template of the page
that call the component.

T4: including javascript in a component (solved)

[Ivano Luberti]

Actually the error was in the html template of the component:
The @Script refers to the text field component barCode but it is written
before the the component itself. Hence when the file is parsed the the
text field component doesn't exist yet.
I have put the Scrtp declaration after the /form tag and it works.

Re: T4: including javascript in a component

[Ivano Luberti]

I have wrote the solution I have found before reading this.
Actually It was enough to put it after the form.
The null component was the text field component not the Form.
You almost got it because sure the position of @Script matters.

It seems that getForm returns something even if the form has already
been rendered.

Andreas Andreou ha scritto:
 You don't specify which object you've found to be null... but anyway, let
 me try...

 looking at the FormFocus.script code from
 http://tapestry.apache.org/tapestry4.1/components/general/script.html
 i see ${component.form.name} and ${component.name}, so either
 component or component.form is null (according to the error message)

 Looking at the javadocs for AbstractFormComponent
 http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/form/AbstractFormComponent.html
 I read
 getForm() : returns the IForm which contains the component, or null if
 the component is
 not contained by a form, or if the containing Form is not currently rendering.

 Finally, looking at your code I see that @Script is outside the @Form,
 so according
 to the javadocs, getForm() should indeed return null !

 The cure? move the @Script inside @Form - or rewrite the script so that it
 doesn't use getForm() perhaps...

Re: T4: including javascript in a component

Correction: putting the @Script solved the null pointer but the
generated javascript was incorrect.
I had to put it before the end of the Form.
You were right Andreas

Re: About T5 integration modules

[Ivano Luberti]

Thiago, every time I see your solutions and the easyness with which you
find them I wonder how you have learned to use Tapestry.
Do you are involved in design and development of  Tapestry core  ? Are
you a committer that hase learned by using it?
Knowing that could really show the way to others , wouldn't it ?

 I agree with you but I don't think that is the issue here. The
 question was how come with Frameworks such as Wicket there is an
 explosion of integrationmodules written and well documented whereas
 in Tapestry there is only a
 handful. Is this because Tapestry is too complex for achieving such
 goals?

 No. Some years ago, when Tapestry was still in its 5.0.5 version
 (pre-pre-pre-alpha), I wrote a very simple Hibernate integration
 package in Tapestry-IoC, including automatic transaction management. I
 was a complete T-IoC newbie then. I wrote it in 8 hours, most of them
 dealing with the transaction management itself, not with T-IoC.

 Summary of the reasons Tapestry and Tapestry-IoC don't have the same
 number of integrations as Wicket, as discussed recently in
 http://old.nabble.com/Discussion-to26889452s302.html:

 1) Someone has to write them. Time is needed for this.

 2) Wicket is way older (4.5 years vs 1.5 years), so the Wicket people
 had 3x more time to write them than the Tapestry people.

 3) More people use Wicket than Tapestry (I don't have any figures), so
 the total amount of time for writing integrations is larger.

 Sometimes, technology-related issues have non-technology causes. And
 sometimes the best option is not the mostly used. Example: Struts
 until some time ago, JSF now.

Re: [Tapestry Central] Next Steps for Tapestry

[Ivano Luberti]

Howard, why don't collaborate with Igor to have the book in Engllish?
Instead of starting a new project for it you can try to have Igor book
as a starting point or even better a final point and only have to
translate a commonly reviewed version and publish it together .

I understand you want to have T5 up to date against the competition but
really the book is mandatory if you want to have people to use it
consciously and having it only in German means to exclude the great
majority of the web developers.

If you go ahead with it I could help in reviewing it and I also suggest
you try to use some list members as an help, like it was made for the
web site.

 Also the book can be written by other people but you are the only one who
 can work in the code.
 i think that any improvement you maid (faster requests or richer web apps)
 is going to be great and i can’t wait to see it.
 cheers and sorry for my bad english.

 Hi,

 AddRow and RemoveRow are nice features of AjaxFormLoop, but I would rather
 use UpdateRow or SubmitRow functionality.

 I would like to have option to change and save some records and submit them
 to server (without submitting the whole form) and also get server-processed
 record back to its position - this would be extremly handy when you want to
 have inline editor functionality in long list of complicated records.

 If there is such a option already available, then I would appreciate if
 someone could point out directions :)

Re: T4: question about IEngineService and outputstream

[Ivano Luberti]

Well, it seems really a long work to deduce from that page how to write
the few lines of code you have suggested to me.
Now I understand there is no point in creating new docs for Tapestry4.1
but I hope that the new docs Howard is writing for T5 will have an
how-to section that make able T5users to quickly find a way to solve
recurrent problem like this.

Thanks again Andreas.

 Ok it worked: just a curiosity. Is there some documentation explaining it?
 I tried browsing Hivemind but couldn't find it.

T4: question about IEngineService and outputstream

[Ivano Luberti]

Hi, this one is a little off topic.
I have used T4 and Apache POI  to generate an XLS  and  PDF files that I
return to the client using a T4 IEngineService that write to the
outpustream.

It worlks quite well but I have two problems:

1) to allow access to pages only to authenticated user I use this method:

@InjectState(user)
public abstract User getUser();

where User is an ASO whose value is set at authentication time.
How can I use the ASO insisde the Service.


2) when the user opens the file (through PDF plugin or using the option
to open it with an application installed on the PC given by the browser)
the file is named app, which is the inernal link. How can I customize
the name given to the file automatically saved from the stream?
