SSH Tunnel in SQL Dev 4.0.3

Oracle SQL Developer and Oracle SQL Developer Data Modeler got a new version (4.0.3).

You can now setup an SSH tunnel in your connection - it saves you to setup a tunnel first.



This new release also feels a lot faster to me.

SQLDeveloper and SSH Tunnels

I saw @krisrice post this

I’ve been using SQLDeveloper for a long time now and have always setup my SSH Tunnels separately (using tools like Meerkat). So I thought I’d take a look at how easy it is to use SSH Tunnels natively with SQLDeveloper.

Turns out it’s incredible simple to configure, simply (more...)

XML Parsing Error: no element found Location: …

I am just working on an application which is supposed to be exposed to public users. I created a simple ajax process there which gets a value of an application element and does something based on the value. While calling the on demand process I am getting this error while not authenticated:

XML Parsing Error: no element found Location: moz-nullprincipal:{6492ed13-2b81-4989-938c-7c19121f419a} Line Number 1, Column 1:



After searching for this error in combination with APEX I (more...)

Mein APEX Vortrag bein Orbit in Bonn

Am 05.11.2014 halte ich einen Vortrag über Rapid Application Development bei Orbit in Bonn. Dabei wird auch noch mein Freund und Kollege Tobias Arnhold sein. Er wird über die Themen Plugins und Reporting sprechen. Anschließend zeigt Frank Weyher (der ebenso ein guter Kollege und Freund ist :)), wie man APEX mit Office integrieren kann.

Die Themen sind sicherlich interessant und eine Anmeldung lohnt sich sicherlich. Der Link zu der Veranstaltung finden Sie hier.

What happened at the first ORCLAPEX-BE Meetup?

Yesterday I attended the first ORCLAPEX-BE Meetup. Very well organised by Dimitri and Roeland. Remarkable fact: I was not the only "foreigner" as around 30 - 40% of the - around 16 - attendees where Dutch! So Meetups can even easily cross borders ...




So after some initial socialising.... 
... ... Roeland explained the concept of these kind of meetups.






In the next hour Dimitri went over all the great new features of APEX5, like Page Designer, (more...)

APEX 5.0: Bye bye Tabs, welcome to Navigation Lists

In previous versions of Oracle APEX (< 5.0) you could use Tabs for the navigation in your application.


Tabs were not that flexible, they were typical on top of your page in a specific look and feel. Since APEX 4.x I started to dismiss using Tabs in most of the cases, instead I would use a List with the "Page Tabs" template if people wanted that look and feel.

APEX 5.0 introduces (more...)

APEX – Default Branch on Submit

Yesterday I spent two hours on debugging one of my applications and searching for an answer. Of course, the problem was caused by myself. Here is what happened:

I copied a page and deleted the region including buttons and items using the Cascade to Delete Buttons option.



Then I created a form and had there a process on submit to upload files in my table. Everything was working fine except the fact that after the (more...)

Your Kscope15 abstract is due today (or before Oct 15)!

It is still a long time before Kscope15. But if I look at the website .... I can hardly wait! 
A good conference needs a good time for preparation. An awesome conference .... needs even more time. So that's why we need your abstracts a.s.a.p. After the close every member of the review committee will go over every abstract and will give it a rating and a comment. When that's all done, the (more...)

First ORCLAPEX-NL Meetup !

Earlier this year Dan McGhan - inspired by local JavaScript meetups - started the first Oracle APEX Meetup. Since then it has gone viral. As you can see on ApexMeetups the meetups are more or less global nowadays!
And even in The Netherlands we will officially join this virtual group and have our first ORCLAPEX Meetup on Thursday September 18. The location is central and well known: The Dutch Oracle HQ alongside the A2 highway. (more...)

10 New APEX 5 Features

The last two weeks I wrote a daily blogpost about a new feature in APEX 5. And intentionally I didn't cover the "big" features, like the new Page Designer, the Modal Pages, the Universal Theme etc as these probably are - or will be - covered by other people. So in my 10 blogposts I covered "Ten Tiny Things" ... 
For those who missed it - all or parts of it - herewith (more...)

APEX 5 New Static File Features

In APEX 4 you could upload files - like CSS files, JavaScript files, Images and whatever else you like - into the APEX Repository. When you navigate to Shared Components, there is a Files section that offers three different options:
CSS Files are always uploaded (and changed !) for the whole Workspace. For Images and Static Files (usually JavaScript) you could choose whether they should be available for the whole Workspace or for a specific (more...)

APEX 5 New Package Features

To get a proper list of the new packages and API's APEX 5 provides us, we have to wait for the documentation of course. But if you're impatient and want to now more, you can get a list of all package procedures and functions by running this SQL on the APEX 5 Early Adopter instance:


select distinct s.synonym_name, p.procedure_name
from all_procedures p join all_synonyms s on p.object_name = s.table_name
where p. (more...)

My Oracle Openworld APEX Sessions

Oracle Openworld 2014 is just around the corner (it’s still not too late to register) and I’m going to be presenting a couple of sessions -

  • Oracle Application Express + Node.JS: A Primer [UGF5222] - Sunday, Sep 28, 2:30 PM – 3:15 PM - Moscone South – 300
  • Testing Oracle Application Express: Removing the Boring from Testing [CON5219] – Thursday, Oct 2, 2:30 PM – 3:15PM - Moscone South – 303

I presented these sessions (more...)

APEX 5 New Authorization Evaluation Point Features

In APEX 4 you can define Authorization Schemes. This is a very useful feature to prevent code repetition all over the place. For instance and Authorization Scheme "Is Admin" might use a select on one or more tables (or web service calls or whatever is necessary) to determine whether a user, the :APP_USER, has an Admin role or not. And you can use any value in session state, like :APP_ID or :APP_PAGE_ID in your query (more...)

APEX 5.0 New Features Schulung

Unsere nächste Schulung hat APEX 5.0 New Features im Fokus. Diese findet im Dezember am 08. und am 09. in Bensheim statt. Wenn Sie auf diesen Link klicken, können Sie die Details anschauen und sich ggf. anmelden. Dieses Thema is sehr spannend und viele neue Features bzw. Änderungen kommen auf uns zu. Wir denken, dass Dezember der richtige Zeitpunkt dafür ist, damit anzufangen.

DOAG 2014 – Vortrag zum Thema: Dynamisches Arbeiten mit Grafiken in APEX

Mein diesjähriger DOAG Vortrag ist am letzten Konferenz-Tag  
20.11.2014 um 9:00 (Raum Istanbul)

Link:  
http://www.doag.org/konferenz/vortrag_details.php?locS=0&kid=459293&tag=3&id=484637

Auf was könnt Ihr euch freuen?
Ich zeige einen Lösungsansatz mit dem man Grafiken dynamisch nutzen kann, ohne viel Programmieraufwand zu investieren.

Beispiel:
Hafen mit dynamisch erstellten Booten und erweiterten Informationen.
In der Präsentation, die wieder eine APEX Anwendung sein wird, werde ich auf unterschiedlichste Beispiele eingehen und den Code im Detail erläutern.

Also sehen uns auf der DOAG!


 


Interested in Oracle APEX in Belgium and around? – join ORCLAPEX-BE Meetup

Over the last months different Oracle Application Express (APEX) meetups were initiated around the world. You can read a bit of background on how the meetups started on Dan's blog.

I think it's a great idea to have local meetups to meet other people working or interesting in APEX too. When you just start with APEX it's interesting to talk to other people how they got started. But equally for more seasoned developers it's a (more...)

APEX 5 New Substitution Syntax Features


You've probably all heard about XSS, a.k.a. Cross Site Scripting. One of the ways you make yourself vulnerable to XSS is by creating JavaScript in your APEX applications that accepts unescaped user input - either direct or data retrieved from the database.
As a - very stupid and simple - example, create a Page with a Text Item (say P3_TEXT).  Next create a Dynamic Action that executes this snippet of Javascript on Page (more...)

APEX 5 New Runtime API Lockdown Features

In APEX 4.x the developer could implement a feature that involves a call to the APEX API. E.g. you could create new pages on the fly if you would like to (just examine an export file for the how-to). You could drop an application using a procedure from the APEX_INSTANCE_ADMIN package. You could drop a user using APEX_UTIL.REMOVE_USER. If this is all on purpose and secured than that's fine. But maybe you (more...)
