Oracle APEX Listener – support for Apache Tomcat

The Oracle APEX listener is one possible gateway to run Oracle Application Express besides the Oracle http server (OHS), the embedded pl/sql gateway (which is the http server included in the Oracle database as part of the XML DB) and other open source alternatives.

Being implemented as a J2EE application it needs a servlet container to be deployed in. Finally, due to popular customer demands, the Apache Tomcat servlet container is (again) supported. Many customers (more...)

Some help with the Oracle APEX Theming Competition 2014

ODTUG announced a few days ago the Oracle APEX Theming Competition.

Make an awesome APEX theme and you may win some cool prices!

In the Learning Resources on the ODTUG site you will see a reference to my presentation of last year "Advanced Responsive Design in APEX". In that presentation I showed a lot of live demo's from different aspects of Responsive Design: here's a quick overview of what I covered:

The evolution of APEX Evangelists

Every year we at APEX Evangelists come together to discuss the past and the future of the company.
In the past 7 years a lot has changed; the APEX market changed, the community changed, we personally changed, …

We really like APEX, we are all passionate about it, we love to have technical discussions with each other and come together to share our thoughts, but we also like our independence and make our own trade-offs (more...)

Setting and retrieving CLOB values in Apex

Imagine you have a textarea in your app where you want your users to be able to type in large quantities of text, click a button to store this in the database and then later retrieve this large quantity of text and redisplay it in that textarea.

You can’t do this as you would with other page items (i.e. just submit the page and have the values stored in session state). Any value over (more...)

Passing more than 10 values with apex.server.process

You may be familiar with the apex.server.process function exposed by Apex’s Javascript API. It allows you to asynchronously interact with Apex Application Processes.

A simple example would be.

 

Apex Application Process

HTP.p(‘You passed “‘||APEX_APPLICATION.g_x01 ||’” as the value for x01. ‘);

HTP.p(‘You passed “‘||APEX_APPLICATION.g_x02 ||’” as the value for x02. ‘);

HTP.p(‘You passed “‘||APEX_APPLICATION.g_x03 ||’” as the value for x03. ‘);

APEX 5.0 (EA): CSS Calendar

APEX 5.0 allows you to create a new Calendar type, called CSS Calendar.

The CSS Calendar is based on Full Calendar 1.6.4, at the moment of writing, the current latest production release. The creator of this JQuery plugin, Adam Shaw, is currently working on version 2. A few days ago he released beta 2. It remains to be seen which version of Full Calendar will make it in the final (more...)

APEX 5.0 (EA): Feedback Page

One of the first things I do when creating a new application is enabling the feedback mechanism in combination with Team Development.

Click the Create Page button in Application Builder and select "Feedback Page":


The next step looks like this:


The Page Mode can now be set to Modal, so instead of a popup it will render as a modal.

Note that in the EA1 version there are some known issues with the Feedback Page, (more...)

APEX 5.0 (EA): Creating a new application

Lets see how creating a new Database application works in APEX 5.0 and what was changed compared to APEX 4.2.

In the Application Builder you start by hitting the Create button.


There are a couple of improvements here:

  • You'll see APEX 5.0 includes a complete new set of icons which are flat and fresh and immediately give you an insight what the button is doing. This is throughout the entire release.
  • The (more...)

APEX 5.0 (EA): Overview

Now that APEX 5.0 EA is out, it's time to do a deep dive in the new features of this early adopter (EA) release.

Overall this new version of Oracle Application Express tries to put even more power and speed in the development. The UI is made simpler and cleaner with a fresher look and feel.
Not every part of APEX got an overhaul in EA1, it remains to be seen if in EA2 (more...)

APEX 5.0 – New Features – Sub Region – Region Position

One of the first things I checked in APEX 5.0 EA was the region positioning of the sub regions. I was positively surprised to see that I can now position the regions next to each other as well. In earlier versions the only option was underneath. Having this possibility it will be much easier to create complex forms where you need to take care of positioning multiple items in more than one column. At (more...)

APEX 5.0 – early adopter is cool

This is definitely the best APEX version ever. I just tested it and it took less than a couple of minutes to get used to it. You know how hard it is to accept major changes. This time it was easy. The changes made in the builder will for sure increase the productivity although this was never a weakness of APEX. There are of course some things missing (or I just couldn't find them) like (more...)

APEX 5.0 Early Adopter has arrived

Suddenly a big thunder rolled through the APEX community -> Version 5.0 has arrived in an early adopter version, as published on Joel Kallmans Blog (as usual on a friday, late night over here in europe).

Over the past 10-15 month we saw numerous presentations of what we can expect in APEX 5, and many of us had our own ideas.

As soon as I got word through twitter I applied for a workspace (more...)

APEX 5.0 (EA) Page Designer video’s

APEX 5.0 early adopter is about to be released in the public.

Requesting a workspace is not working yet at the time of writing this post, but I expect it can be opened every moment now.

APEX 5.0 carries many new features, one of the biggest is the new Page Designer which should increase developer productivity even more. David Peake recorded some videos, here's the APEX 5.0 Page Designer Overview:

Increase post back size in Glassfish

I created a small mobile APEX app for my football team where they can upload pictures to the app.


Sometimes saving the picture worked, sometimes it didn't. If it didn't work I hit the following error: "Post too large". It turned out that my Max Post Size in Configurations - server-config - Network Config - Network Listeners - http-listener-1 under HTTP was set too small.


After increasing it worked like a charm.
