APEX Listener Confusion

I just downloaded and installed version 1.10.xx of the APEX Listener. After solving some problems - most of them due to "no need reading the manual", I've got it up and running. Now I can access APEX choosing from a variety of ports: APEX Listener, EPG, Apache's mod_plsql.

A few things are confusing me though:

1. At last weeks ODTUG was announced that the APEX Listener made it into production (the version number also indicates that status). But if you're looking at the official download site, it says: "The Application Express Listener is currently an early adopters release and is not supported by Oracle Support.".  So what is the - current - truth?

2. Reading the documentation (after all), I noticed: "The Oracle Application Express Listener supports the following Java Enterprise Edition application servers: Oracle WebLogic Server 11g Release 1 (10.3.3), Sun GlassFish Enterprise Server 3 +, Oracle Containers for J2EE 10.1.3.4 or higher". The funny thing is that if you download and install the OTN Database Development Appliance (which is great btw), Tomcat is used as webserver. In the early (or earlier?) adopter release, also Tomcat was mentioned as an option (and Glassfish wasn't).

3. For a reason I haven't figured out yet, I can't get to the listenerAdmin page (http://localhost:8888/apex/listenerAdmin). Username and password defined in the tomcat-users.xml are accepted, but I don't get the nice admin page I expected (the same when running the /Config at first). If you have a solution, please add it to the comments!

The good thing is that the APEX Listener (on Tomcat) starts up as a breeze now and the APEX pages perform nicely!

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

It's happening again ... running for the ODTUG Board of Directors 😉

For the third time in a row I'll be running for ODTUG's Board of Directors. But after ending as a runner up twice, I am sure I'm going to make it this time! But not without your help!

My campaign statement this year is:
I have been attending and presenting at Kscope conferences since 2007. This not only resulted in a vast amount of knowledge, but also - and even more important - a huge number of friends from all over the globe.  I want to see ODTUG grow and spread this community feeling even more! 
My experience as an attendee, presenter and content lead has provided the basic foundation to be a director. Next to that, my personality and (global) network will be beneficial to the whole board and organization. 
Since March I have served on the Board of Directors in a limited term for a Director who stepped down due to a career change. This has allowed me to have unique insight of all the things that are going on in and around the ODTUG organization. As the train was already ro…

A review of APEX World 2017 - Day 1

Last week the SS Rotterdam was the beautiful location of the largest gathering of APEX Developers worldwide. With around 380 (!) attendees a new high was set. And they came from all over the world : I spotted people from The Netherlands, Belgium, Switzerland, Austria, Croatia, Germany, Denmark, Norway, UK, Ireland and the USA. And I even might have missed one or two ….

The event started with a presentation by the “father of APEX”, Mike Hichwa, talking about "Oracle APEX Past, Present and Future”. Of course everyone is curious what the APEX future might bring: Friendly URL’s, automated testing, more JSON, concurrent APEX versions, third party Oauth 2 authentication (think Facebook, Google), APEX app diff and more, a lot more, REST capabilities. And now we have to wait for APEX 5.2 … and that might take a while! 
After this keynote, the conference split up in three tracks. After the coffee break I returned to to big theatre where Geertjan Wielenga talked about "Finally Javas…
