Hi Charith,

as I've told you before the proposal you submitted contained nothing of what you came up with in the 
last days. The proposal deadline was on April 9th and you knew that. At that point you were nowhere 
close to a proper proposal nor did you show that you understood the problem or have the required 
knowledge to carry out your proposal.


I'm sorry but we just couldn't consider your proposal. I recommend that you try again next year and 
I urge you to start working on the proposal MUCH earlier then you did this year.

Since this will be an add-on module it is OK for it to depend on LGPL-licensed 
software.

I think that's the only viable way of doing it without delegating the

Hi ,

 I can't see anything in RenderSupport that
> would help render or stream images to be shown to the user.



Yes, It is true that it is unable to render the PDF into image and show ti
the user by using RenderSupport. I tried to render the PDF into image by
using JavaScript with the support of RenderSupport to built my
component "JavaScript-only
PDF viewer".I have given my fully capacity to do it in my way,but ultimately
my total attempt became a waste. But finally I studied something which is
very advantage.

Now I am on the right path to render PDF into image by using Java2D. Java
swinglabs provide PDF rendering library called Java PDF render (
https://pdf-renderer.dev.java.net/). This library has a class called
PDFRenderer (
https://pdf-renderer.dev.java.net/nonav/demos/latest/javadoc/index.html) and
it turns a set of PDF Commands from a PDF page into an image.

I am not pretty sure that above class can be used directly for my
implementations. I think I have to do some customization class or rebuilding
class towards compatible T5. Show the pages to the user easily done by
 using StreamResponse.

thanx,

charith

I'm not following you. I can't see anything in RenderSupport that
would help render or stream images to be shown to the user. Rendering
should be done by Java code, using code you'll write or some open
source package that does it. Streaming content to the user should be
done by a StreamResponse or a Dispatcher.

Hi Uli,

Now looking Interface RenderSupport  package , I think it can be use full
to enders the PDF to images and  shown to the user. This package support to
all T5 component that render and also help to JavaScript generation.

Interface RenderSupport(

),

Re: Google Map Module and JavaScript-only PDF viewer component | GSOC2010

[Ulrich Stärk]

Yeah, but that's not what Thiago and I had in mind. We'd rather want some kind of Tapestry service 
that renders the PDF to images and a JavaScript control that communicates with that service and 
shows the pages to the user.

*
*

*Proposal Abstract:***

Apache Tapestry is an open source java framework. Tapestry component make
easer to developers creating dynamic, robust, highly scalable web
applications in Java.Google Map component provides an interface to the
Google map API with Tapestry5. PDF viewer component provide to Tapestry user
view PDF document through the web browser. Both components are mainly based
on Java Script.

*
*

*Deliverables*


   - Implementation of Google Map component
   - Implementation of JavaScript-only PDF viewer component
   - Documentation to support continuation of the project



*Overview*

*
*

*Google Map component***

This component provide users to a clickable map for entering
latitude and longitude as well as it can  add content to the map through a
variety of services, allowing you to create robust maps applications on your
T5 web application.

Google Map component can be used to create interactive maps with various map
markers. I’m hoping to implement this module by using Tapestry5 Ajax package
and Java Script (Tapestry5AndJavaScriptExplained) make an interaction with
Google Map API.



*JavaScript-only PDF viewer component*

These components allow to viewing PDF file directly in web
browser .Now look at my implementation of this component. One of the
effective and powerful way to view PDF in web browser by using Java Script.

My implementation includes classes, object and method that
enable you to easily manipulate PDF file, provide database connections and
other use full things. To render PDF, I will do render the whole document at
once and cache the pages, then contents shown to the user. Ajax is used to
load the content asynchronously.



*Project Plan*

*I have planned the project under 4 steps as follows*

*Step 1: Initial Planning and Designing*

*I will look at both Tapestry 5 framework Google map API then will create a
basic design for Google map component.** *In* *PDF viewer component I will
design all the Java Script classes, method and workflows. **

Estimated Completion: 23ed May 2010* *

*Step 2: Implementation*

I would start working on the code. Deliverable(s): Prototype and
documentation for mid evaluation

Estimated Completion: 11th July 2010**

*Step 3: Improvements and Testing*

Modifications or improvements suggested at the mid evaluation would be
completed in this step. Write unit tests for finished segments and Test
Component.

Estimated Completion: 9th August 2010**

*Step 4: Final Product and Documents*

With the completion of this step, will finish the Google Map Component and
JavaScript-only PDF viewer component for T5. Necessary documents would also
be present with the final products. Deliverable(s): Final products and
documentation.

Hi Uli ,

First of all I'm thank you for your comment :-)


I wonder though, why you would need SOAP for the JavaScript only PDF viewer?


Because I think Applications written in Java can easily integrate JavaScript
only PDF viewer component with Web services using SOAP.

Now i'm think  load the contents asynchronously via Ajax good.


> How will you render the PDF so that the contents can be shown to the user?


I'm planing to use render the whole document at once and cache the pages
method.

Now i will revise my proposal and need any suggestion about Google
map component.


Cheers,

charith

Hello Charith,

that sounds much more like a real proposal ;).

I wonder though, why you would need SOAP for the JavaScript only PDF viewer? I think the easiest way 
would be to bind the PDF contents to be viewed to some parameter of the PDF viewer component, or 
load the contents asynchronously via Ajax.


How would you go about anyways? How will you render the PDF so that the contents can be shown to the 
user? Will you do that on a page-by-page basis or render the whole document at once and cache the 
pages? Will there be some server-side Tapestry service (not a webservice) involved?


You see, there is still much to think about, so please revise your proposal.

Cheers,

Uli

*Proposal Abstract:***

Apache Tapestry is an open source java framework. Tapestry component make
easer to developers creating dynamic, robust, highly scalable web
applications in Java.

 Google Map component provides an interface to the Google map API
with Tapestry5. PDF viewer component provide to Tapestry user view PDF
document through the web browser. Both components are mainly based on Java
Script.

*
*

*Deliverables*


- Implementation of Google Map component
- Implementation of JavaScript-only PDF viewer component
- Documentation to support continuation of the project



*Overview*

*Google Map component***

 This component provide users to a clickable map for entering
latitude and longitude as well as it can  add content to the map through a
variety of services, allowing you to create robust maps applications on your
T5 web application.

*Google Map component** can be used to create interactive maps with various
map markers*. I’m hoping to implement this module by using Tapestry5 Ajax
package and Java Script (Tapestry5AndJavaScriptExplained) make an
interaction with Google Map API.



*JavaScript-only PDF viewer component*

 These components allow to viewing PDF file directly in web
browser .Now look at my implementation of this component. One of the
effective and powerful way to view PDF in web browser by using Java Script.

 My implementation includes class, object and method that enable
you to easily manipulate PDF file, provide database connections and other
use full things. Tapestry5 can easily interact with the PDF viewer component
using Simple Object Access Protocol.

*
*

*Project Plan*

*I have planned the project under 4 steps as follows*

*Step 1: Initial Planning and Designing*

*I will look at both Tapestry 5 framework Google map API then will create a
basic design for Google map component.** *In* *PDF viewer component I will
design all the Java Script classes, method and workflows. **

Estimated Completion: 23ed May 2010* *

*Step 2: Implementation*

I would start working on the code. Deliverable(s): Prototype and
documentation for mid evaluation

Estimated Completion: 11th July 2010**

*Step 3: Improvements and Testing*

Modifications or improvements suggested at the mid evaluation would be
completed in this step. Write unit tests for finished segments and Test
Component.

Estimated Completion: 9th August 2010**

*Step 4: Final Product and Documents*

With the completion of this step, will finish the Google Map Component and
JavaScript-only PDF viewer component for T5. Necessary documents would also
be present with the final products. Deliverable(s): Final products and
documentation.
