ADF 11g : Show PDF in a Popup

In one of my previous posts I showed how to use ADF popup components to display external content such as webpages like wikipedia in an inline frame. Based on this post a colleague of mine tried to display a PDF document. That didn't work. In this post I explain how you can use a servlet to open a PDF document in the inline frame. I will not explain how to invoke popups. If you need to know how to do that, refer to the post mentioned earlier.

How to create the servlet ?

The solution for showing a PDF in a popup is to use a servlet. It's possible to have a servlet deliver PDF content to the browser by specifying the content type of the servlet response to be the 'application/pdf' MIME type via 'response.setContentType("application/pdf")'.
In JDeveloper you can create a HTTP servlet very easy via the new gallery. I decided to call the servlet ShowPdfServlet which actually is a pretty descriptive name for this servlet.

For the servlet mapping I accept the d…

ADF 11g : Printing Directly From Your Application

Last week I was asked this question : "Can we print directly from within our ADF Application, without invoking the printer dialog ?" I wasn't sure but after some investigation the answer was clear. Yes you can ! Here is how...

I decided to create a print start up form where I can select printers and print the document. Most of the functionality needed is provided by the Java Print Service API.

Selecting available printers

I start with a way to show all printers available to the session. For that I simply use the PrinterServiceLookup.
PrintService[] printers =
PrintServiceLookup.lookupPrintServices(null, null);

The result I can now use to create an Array of SelectItems in order to make the list available in the application.
1: public SelectItem[] getAllPrinters() {
2: if (allPrinters == null) {
3: PrintService[] printers =
4: PrintServiceLookup.lookupPrintServices(null, null);
5: allPrinters = new SelectItem[printers.length];
6: for (int i = 0; i < printer…

ODTUG Kscope 11: My story on ADF in the Fusion MiddleWare Track

From June 26th to June 30th the KScope 11 conference was in Long Beach California. Nice setting for a great conference. It was the first time that KScope had a Fusion Middleware Track. For me it was a very busy conference with three presentations, handson workshops, live demonstrations and a Boff session with the EMG. In this post some of my highlights.

Friday and Saturday
On Friday in the airplane and Saturday in Long Beach I wrote a review for Sten Vesterli's book. The review can be found here on the AMIS Technology Blog.

Sunday Symposium
The symposium started very early. That is 7.30 including breakfast and registration.
Then some great sessions on ADF and SOA and Webcenter. Chris Muir and John King talked about ADF, Sten Vesterli and Hajo Norman about WebCenter, Lonneke Dikmans and Chris Judson talked about SOA and BPM. Finally Madhuri Kolhatkar \was presenting on User Experience Design Patterns. She pointed out a very usefull resource where you can find OBIEE Design Patterns that…
