The web began as a platform for browsing, finding, and exchanging documents. Over the past ten years the web has moved beyond this document-centric role, and is now a platform for exchanging data.

We typically refer to web sites used for data exchange as web applications. The next major evolution of the web is underway as web applications become more interactive and useful. The industry now refers to these next generation web applications as rich Internet applications or RIAs. Like the web, PDFs are also evolving into more than just a document exchange technology. When RIAs are inserted into PDFs, this familiar format for documents becomes a method for exchanging and interacting with data.

The primary benefits of using PDFs for data exchange are that PDFs can easily be secured, emailed around, and accessed when offline. You will need Reader 9 in order for this to work.

First load the Flex Dashboard application application in your browser. Now you should be looking at the same data inside of a PDF! You can even save the PDF locally and view it when disconnected.

You can also refresh the data from the server from the PDF or from the browser. This works by using a template PDF containing the Flex application without any data. You can also create these PDFs in a nightly batch process. You need several pieces to build a portable RIA. First, you need a Flex application that the user will interact with in their browser and inside a PDF.

Second, you need some place for the Flex application to get its data. Third, you need a PDF template and a server that can insert the application data into it when the user requests a PDF. I used the following steps to build these pieces:. The application needs some data so I created a JSP that generates some fake and random sales data. This data is returned from the server in XML format. Because of this I ended up using PHP for my public demo.

However, for the purposes of this tutorial I will just use a simple JSP file. Here is the file, data. You will also need to add a crossdomain. For more information on secure cross-domain communication in Flash Player see:.

Before I could use the typical sales dashboard in the demo, I first had to create that dashboard in Flex. Luckily this was easy since one of the out-of-the-box LiveCycle Data Services samples has a dashboard. I made a few modifications to the dashboard and then added it to my Flex application.

Here is my application you will need the Dashboard source code from the LiveCycle Data Services sample application for this to compile :. I then added some necessary configuration code to my web. To create these classes I first set up a new Java project in Eclipse. Notice that this class references a PDF file, dashboard. This is the PDF template that will be created in Step 7. This class reads the PDF byte array from the session and returns it to the user as a file.

Storing the PDF in the user session as this demo does is certainly not a scalable approach, and therefore it should not be used in production. Now your back end is set up!

Start or restart your app server and verify that there are no errors on the console. If you choose to use mine then you can skip this step. First create a new blank PDF in Acrobat and save it.

The final PDF in Designer should look like:. When your Flex application runs in the browser you want it to get the live data from the web.

This allows the application to work when the user is disconnected. For bonus points I also added the ability for users to refresh the data in the PDF when they want to. When this class is instantiated it checks to see if the application is running inside a PDF Reader.

Also if the user updates the data while in the PDF then the local form field is updated but the user would need to save the PDF for the data to be persisted for the next time the PDF is opened.

To use the PDFCacheManager class simply create an instance of it and specify the id, url, and optionally a fault handler:. When the Flex application has fully initialized I ask the PDFCacheManager to get the data either from within the PDF if the application is running inside Reader or from the network if the application is running in the browser:. Here is the code for that class:. Notice that the data is wrapped in the and XML tags.

When the result is returned by the server the client opens a new browser window pointing to the download servlet that initiates the PDF download. Notice that the data passed to the generatePDF method is pulled out of the pdfCacheManager that was created in the previous step.

Also the button is only made visible when the Flex application is not running inside a PDF. Hopefully your Flex application compiles and is working in the browser. The final step is to update the PDF template and include the Flex application into it. Also one thing to note is that you are using the same application for the browser and for the PDF. You can create different applications if you want to and still use much of the same code.

But for this demo using the same Flex application for both mediums works fine. Browse and select the SWF file for your Flex application. Click OK. Then select the image of the Flex application and resize it. The PDF should look like the following:.

Everything should now be ready to go! If the PDF opened in your browser you can save it to your local file system and load it in the standalone Reader. Download the source code for tutorial.

Picture this - you log in to a popular website to make a purchase. You search through a number of products researching which ones best fit your needs. Your order is complete and you return to the shopping cart, enter all your shipping information and payment details only to be presented with an error at the end of the process. This frustrating experience is one that consumers encounter day-in and day- out because of poorly architected sites that are not designed with the user experience as the number one mantra. As your clients struggle with how to deliver better user experiences, many are reaching out for technology to help them create a more immersive and responsive environment. Originally coined by Macromedia in a white paper, RIAs have since grown into a widely accepted technology and are now the direction of choice for many new web development projects. According to Gartner Research, nearly 60 percent of all new application development will include RIA technology by

Rich Internet Applications

Shows you how to integrate Flex and Spring to create a powerful platform for building robust Rich Internet Applications. The framework was built for use by developers and follows traditional application development paradigms rather than the timelinebased development found in the Flash Professional authoring tools. The Spring Framework is one of the most popular ways to build enterprise Java applications.

The Flash that you thought you knew has changed. Pay attention, because there will be a quiz at the end! The transformation that Flash has undergone has been occurring for some time, and many developers are aware of it. Every day I hear of a developer building a powerful new application for the Flash runtime that performs tasks like connecting to enterprise solutions powered by SAP or Oracle — and all with the full blessing of those vendors. Flash has evolved beyond the Skip Intro button for which we used to hate it, and has become ubiquitous — helping the browser perform way beyond the text rendering that it was first built for.
