Re: Help with using DWR with Tapestry

RE: About T5 integration modules
Interesting. I'd hardly call myself even an advanced-intermediate Tapestry user (some of the stuff you guys talk about is way over my head!) but really, is it that difficult to create a Dispatcher and custom page annotations?! I included simple security with roles very early on in my webapp by going the page annotation route because it was a) understandable and b) simple to implement by following the examples I'd seen. I had even less of an understanding of Tapestry than I do now. I found it very easy to understand and code, and it works so well. I shudder to think how long it would have taken ploughing through documents on security solutions, like Spring Security, when all I wanted was half a dozen roles and some way to mark my pages as general viewing or requiring login under a certain role. As I've said all along, I think the only thing lacking big time for Tapestry is clear, easy to understand documentation with good simple examples of each feature. That said - I had no troubles with the above security stuff (and I didn't even have to look at Tapestry source code ;-) Rather than providing large cumbersome bolt-ons for features that may not even solve all problems, I'd rather see well-defined methods and example solutions for particular problems which allows scope for people to customise if they so wish. Isn't that an example of convention over configuration? ;-) It would also be far quicker than developing modules that try to be all things to all people - and perhaps lessen the perceived gap between tech. like Wicket and Tapestry in a much shorter time period. -Original Message- From: p...@sartini-its.com [mailto:p...@sartini-its.com] On Behalf Of Piero Sartini Sent: 24 December 2009 20:34 To: Tapestry users Subject: Re: About T5 integration modules ... Howard, I think people are looking for these kind of integrations because there is no tapestry module allowing them to secure there pages. Of course you may argument that it is easy to build a Dispatcher and define some custom annotations. That's true if you managed to understand how these things work. But if you've just started with tapestry, in my experience this is not that easy. Then you remember about Spring Security or any other solution you are used to and try to make use of it in your new tapestry-world. ...

demo aplication

Is there some idea of how the demo app should be?

Hello Guys, Okay, i give up! I'm very new here! And i'm just a 2nd year college student! I'm learning java only now! And more-over when i hunter the WWW for some good framework to build my WebApp in J2EE. I had to keep my hands on many things. Its during that, i actually got in Tapestry and DWR. Though i stumbled on DWR first, i finally rested with Tapestry, as it actually made my life simpler! And using DWR (soley for 1 reason), i wanted to do, some live username availability checking, (may be u can do it with a custom Component from Scriptaculous, as i told u, i'm very very new here in java and Tapestry, to DWR too). I'm too young in experience to say advantages of DWR over Tapestry or the vice versa. It just makes begineers like me, open my JAW fall.. ;) Nothing more..

T4: including javascript in a component
Hello, I'm trying to include some simple javascript in a component in my

I want my only textfield to get focus when is displayed.
I'm following the instructions provided at:
http://tapestry.apache.org/tapestry4.1/components/general/script.html

specified.
My component looks like this:

The Script template file is the last one provides at:
http://tapestry.apache.org/tapestry4.1/components/general/script.html
the one without CDATA
When I try to display the page I get:
[ +/- ] Exception: Unable to read OGNL expression 'parsed OGNL

source is null for getProperty(null, name)
I have already tried putting a bad component name in the @Script span
and the error changes, so it seem the name is right. I have put a bad
path to the script file and the error changes , then the path is correct.
Can someone point me in the right direction?

Unit testing components with @Parameter annotation
Is there any recommended way of unit testing components that have @Parameter annotations?

Re: Unit testing components with @Parameter annotation
My thoughts are that @Parameter annotation represents an integration between the component and its immediate container or other part of the system. @Parameter(required=true) failures will show up in integration tests. In the rare event that I unit test an individual component, I just use the facilities of TestBase to push values into private fields. Most of my testing is done at the integration level (PageTester or Selenium).

Re: T4: including javascript in a component
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.

I have already tried putting a bad component name in the @Script span
and the error changes, so it seem the name is right. I have put a bad
path to the script file and the error changes , then the path is correct.
Can someone point me in the right direction?

Re: T4: including javascript in a component
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
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.

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: Best server for development and for production?
Juan, If you use the latest NetBeans (6.8) it support compile-on-save/copy-on-save for both standard and maven based projects, which works perfectly (equivalent and better than the deploy on save w/ other app servers) w/ Jetty and T5's live class reloading. For Tomcat Glassfish NetBeans support deploy-on-save ; however, that is slower and somewhat more intrusive . I remember that there were some hurdles w/ getting T5 apps to work w/ Glassfish in the past due to xml parser conflicts, so there were a few things to do. So, to answer the question directly, for me it goes like this : Jetty, Tomcat, Glassfish Cheers, Alex K On Thu, Nov 19, 2009 at 9:30 AM, Toby Hobson toby.hob...@googlemail.comwrote: For development I use jetty along with JRebel.

GAE T5 : Passing a request to the T5 pipeline from a servlet
I've been struggling a bit w/ getting the GAE blobstore API to upload files into a GAE T5 based app. All of the examples include using the blobstore service to create a URL to which the file is uploaded, after which the blobstore passes the control to a URL provided by user, e.g. : url = blobstoreService.createUploadUrl(/upload) // after the upload is done, GAE was supposed to post to this URL My initial take was to use the T5 component resources to create an event handling URL and pass it into the blobstore service, with the expectation that GAE will then post to my event URL at which point I'd post-process the upload. The problem is that it seems that GAE doesn't initiate a new POST request to the given URL, but just forwards the request to it. As a result, because the request is initially initiated to a non T5 URL, the whole T5 magic doesn't kick in and my event handler isn't called. However, if I create a simple servlet, mapped to , say '/upload', it does get called properly. So, the idea I have is this : create a very simple servlet mapped to /upload, and whenever it's called, I'll just pipe in the request into the T5 infrastructure so that my events get called as I want them to. The question here is : if I did that, what entrypoint in the API should I use ? Alternatively, I could certainly look up the T5 registry from the servlet ( I think I know how to do that) and invoke some service in it to post process the uploads. Can anyone point me where I should be looking at for the entrypoint into the T5 processing pipeline that I can invoke from the servlet ? Thanks in advance, Alex K
