JasperReportsIntegration – Full path requirement and workaround

I have just posted an answer to a question that seems like a bug in the JasperReportsIntegration toolkit, that you have to use absolute paths for referencing images or subreports, which is typically a bad thing.

Don't know exactly why it doesn't work, but there is a workaround for that: http://www.opal-consulting.de/site/jasperreportsintegration-full-path-requirement-and-workaround/

Hope that helps,

First blogpost at my own hosted wordpress instance

I have been blogging at daust.blogspot.com for quite some years now ... and many people have rather preferred wordpress to blogspot, I can now understand why :).

It is quite flexible and easy to use and there are tons of themes available ... really cool ones.

The main decision to host my own wordpress instance was in the end motivated by different means. I have created two products and they needed a platform to be (more...)

Oracle APEX Cookbook [Second Edition] – Book Review

Recently the second edition of the APEX Cookbook has seen the light. As I haven’t read the first edition - I know, shame on me - I can’t exactly point out what the differences are, but that doesn’t really matter anyway. I guess no one will buy both versions anyway…

The book follows a different approach than most of the tech books I read (and wrote): Every issue is attacked with a recipe, existing of (more...)

OGh APEX Conference

Last week I was presenting at OGh (ORACLE GEBRUIKERSCLUB HOLLAND) APEX World. My topic was "APEX 4.2 Application Deployment and Application Management". I can only recommend this conference to all the APEX users in Europe. This is definitely the biggest APEX conference on our continent. If you don't travel to ODTUG then this is something you shouldn't miss. They have an international track where you can listen to the well known APEX developers and (more...)

Yet Another Post How to Link to Download a File or Display an Image from a BLOB column

On an internal mailing list, an employee (Richard, a long-time user of Oracle Application Express) asked:

"...we are attempting to move to storing (the images) in a BLOB column in our own application tables.  Is there no way to display an image outside of page items and reports? "

Basically, he has a bunch of images stored in the BLOB column of the common upload table, APEX_APPLICATION_FILES (or WWV_FLOW_FILES).  He wishes to move them (more...)

APEX 5.0 Page Designer Videos

There is a nice series of videos regarding APEX 5.0 Page Designer on YouTube. You can watch it here. David Peake is showing how the new Page Designer works. It is worth of having look at it and much easier that finding it out yourself. Enjoy.

APEX Plugin Page

I just noticed that http://www.apex-plugin.com is programmed using php and jomla. Shouldn't it use Oracle APEX?

APEX IR Query Plugin

I already posted about the function for getting the IR query here:

http://www.deneskubicek.blogspot.de/2013/05/getting-interactive-report-query.html

Now, I decided to create a dynamic action plugin based on that function. The plugin has been submitted to the plugin directory at http://www.apex-plugin.com/ and should appear there soon. If you want to see how it works and download the code, you can do it here as well: https://apex.oracle.com/pls/apex/f?p=43045:1

Oracle APEX Cookbook : Second Edition

I was asked to review this book and write a couple of words about it. Of course I didn't go through all the 444 pages of the book because I don't have enough time. From what I could read and review, I can say that this book contains a lot of well explained examples for almost all APEX features. So, if you are new to APEX and want to speed up your learning process then (more...)

Finally…the official sizing guide for Oracle Application Express

The following question was recently posted on an internal mailing list:
"Is there a sizing/capacity/scalability guide available for APEX?"
I'm always fascinated by this question.  I appreciate the fact that this is a standard, acceptable practice in the industry, and people come to expect it.  How else could architects and planners appropriately allocate resources without some form of estimate?  This impacts capital expenditures and budgets and rack space and energy costs and support costs (more...)

APEX Listener => Oracle REST Data Services


Yesterday a new version of the Oracle APEX Listener was released. The new version is 2.0.6... and the biggest change in this release is the change in name. From now on we won't speak about the "APEX Listener" anymore, but we speak about "Oracle REST Data Services".

The name explains more what the piece of software is doing and it will be less confusing for non-APEX people. Many people thought about the Database (more...)

Why do I attend Kscope?

Kscope14 will be my 6th Kscope event. After New Orleans, Monterey, Washington, Long Beach and New Orleans again (yes, I missed San Antonio), this year Seattle will be the place to be at the end of June.

So why do I spent quite a lot of time and money to visit this event? That's because of two reasons: the content and the fellow attendees. Without any doubt the content of Kscope is best you can (more...)
