Customize the APEX Workspace Login Page

One nagging thing about APEX occurs often to me. It’s the inability to customize the Workspace Login Page. In APEX Instances within corporations you may want to display your own Logo or some custom text explaining your developers what to do and what not. Some lines of javascript and jQuery to the rescue, i build a nice

Pelotonia10

Joel Kallman 22-AUG-2010 22:01


Sorry, this is not a post about anything Oracle-related. But as our dear, departed friend Carl used to say - it's my blog.

I had the privilege of participating in this year's Pelotonia bike tour. What is Pelotonia, you may ask? "Pelotonia is a grassroots bike tour with one goal: to end cancer. Pelotonia raises money for innovative and life saving cancer research at The Ohio State University Comprehensive Cancer Center - James Cancer Hospital and Solove Research Institute."

This event had special significance for me, as our next-door neighbor, Jacob Carlino, was diagnosed with a rare form of cancer earlier this year and is undergoing treatment now. Jacob is 12 years old. A child like Jacob or any person, for that matter, shouldn't have to suffer through this horrible disease. Jacob's father Dave organized a team in support of his son Jacob, and I had the privilege of being on this team. Above is the team - Dan, Matt, Scott, me and Dave. On the front of our shirts is a picture of Jacob who we were honoring with our team's tour.

Pelotonia was a most-impressive and well-organized event. There were over 4,000 riders and thousands of volunteers in addition to a great deal of corporate sponsorship. The estimate is that this one event will raise over $8 million, with 100% of this money going directly to fund cancer research at the Ohio State University Cancer Care Center and Solove Research Institute. The honorary chair of this year's Pelotonia tour was Ohio State football legend Chris Spielman, who he himself lost his wife to cancer just 9 short months ago.

My goal for this blog post? To simply raise awareness of this disease, and to also let the world know that there is an ever-growing army of people right here in Ohio who is contributing in ways small and large to the eradication of this disease. Lastly, I would like to recognize and thank the sponsors of me for this ride - I am grateful for your generous support: Sue, Sergio & Priscila, Jason & Shelley, Eric, Bob & Marge, Matt & Gretchen, Tim & Susie, Anton & Chris, Kathy & Terry, Neil & Margaret, Tom, Nada & Matt, Frank, Harry, and Mike & Anita.

Learning Oracle Application Express (or teaching Angelina Jolie the MC Hammer dance)
4
David Njoku 22-AUG-2010 11:53

I'm a Londoner so, unsurprisingly, I think London is the greatest city in the world (feel free to disagree if you enjoy being wrong). However I do accept that London isn't always that friendly to foreigners. Other major European cities have street signs and directions in the local language and English, but London seems to say to you, "Speak English - or get lost. Literally."

The Apex blogosphere can be a little like that; we often blog about advanced minutiae, perhaps to the exclusion of absolute beginners. This week 2 of my colleagues started learning Apex and so I've decided to put together a little Apex 101 study guide for their benefit and for that of other Apex padawans. (And if you say that this is only tangentially different from a post I wrote 2 years ago my answer is that all blog posts are kinda related; it's like that 6 degrees of separation theory that says, as far as I understand it, that I and Angelina Jolie are practically best friends.)

Where to start: There is only one place to start, and that's at the Oracle Apex website. Sign up for a workspace - it's free and easy. Have a look round, press buttons to see what they do: it's like developing with a condom on - safe, without commitment, and, hey, you can even do it drunk. However, the very best way to really dip your toes into the water is to work through Oracle's 2 Day Developers Guide [PDF link here]. When you're done with that you may wish to return here to flirt with the other tutorials.

Internet resources: Did you know that you're only ever 6 clicks away from an Apex blogger? Fact. We're like LOLCATS, adverts for blue pills for men, and YouTube videos of Rick Astley. Fortunately, the Apex Blog Aggregator has found the best blogs about Apex and, erm, aggregated them. Alternatively, you can go here or even here.

Another internet resource that you'll probably want to bookmark is OTN (which either stands for a. Oracle Technology Network or b. Orangutans Tangoing in the Netherlands. You decide.) The forum's search functionality is more Altavista than Google, but chances are that any question you've got has probably been asked and answered before.

Tutorials: The same way that with each regeneration since the first series in 1963, Dr Who has come back as someone slightly younger and better looking, each regeneration of Apex has resulted in a slicker, more intuitive IDE. However, I attended the Oracle University's 5 day Apex course and found it very useful. You may also want to have a look at SkillBuilders. I've attended some of their webinars and they've been excellent. Hey, why don't you put on a pair of geeky glasses, download some of their past webinars and pretend you're me? Whatever pedals your bike, pal.

Books: If you are the type who prefers to learn from books there is a growing catalogue of Apex books out there. Here's a list. And here are two reviews by a blogger who I respect immensely - and who Angelina Jolie is practically best friends with.

And that's it, my friend, all you need to get started. I'm not going to claim that this blog post has changed your life or that you came to me as a boy/girl and are leaving as a man/woman (unless it's taken you 20 years to read these 600 words), but hopefully you now got all the resources you need to hack your way through the Apex jungle. There's a lot more I can show you (have you seen my MC Hammer dance? No?) but my doorbell is ringing. It's probably Angelina.

Silbentrennung (Hyphenation) in APEX (GER)
4
Tobias Arnhold 20-AUG-2010 23:33

Viele Entwickler in APEX kennen das Problem professionelle gut strukturierte Reports zu entwickeln, deren Spaltenbreiten nicht über die gewünschten maximalen Breiten hinausragen.
Folgende Bedingungen erschweren die einfache Entwicklung von Reports:
- Bildschirmauflösung ist eingeschränkt (1024x768)
- Zu lange Texte in Reports (Spaltennamen, Spaltenwerte)
- Nutzung verschiedener Browser (Firefox, Internet Explorer 6, 7 und 8,Safari,...)
- Übersetzung in verschiedene Sprachen notwendig
- Nutzung unterschiedlicher Layouts mit verschiedenen CSS Eigenschaften

Vor einer Weile habe ich einen Tipp beschrieben der die Problematik ein wenig verbessern kann: Automatic linebreak if word breaks out of table element

Nun habe ich eine wirklich gut Lösung gefunden die mit ein paar einfachen Anpassungen erstaunliche Wirkungen in ihren APEX Reports hervorrufen kann. Das Zauberwort heißt Silbentrennung (Engl.: Hyphenation). Die Lösung besteht darin den dargestellten Text durch ein Javascript Plugin entsprechend der maximalen Feldbreite zu begrenzen.

Dazu wird nach jeder Aktualisierung eine Funktion gestartet, die die Felder entsprechend anpasst.
Die Anwendung heißt Hyphenator, kann in allen gängigen Sprachen dynamisch verwendet werden, ist ein Javascript Plugin und ist hier zu finden http://code.google.com/p/hyphenator/

Ein weiterer Entwickler hat ein passendes Jquery Plugin geschrieben: http://bitbucket.org/webvariants/jquery-hyphenator/wiki/Home

In dieser Kombination ist die Verwendung in APEX 3.2 oder 4.0 denkbar einfach.

Anleitung:
1. Datei downloaden
Downloaden Sie die aktuell stabile Version von hier http://hyphenator.googlecode.com/files/Hyphenator%202.5.0.zip und hier http://bitbucket.org/webvariants/jquery-hyphenator/get/v1.1.0.zip

2. Kopieren Sie das Jquery Plugin auf ihren Webspace (APEX /i/ Verzeichnis)
  /i/Hyphenator/Hyphenator.js (Umbennen von hyphenator.min.js)
  /i/Hyphenator/jquery.hyphenator.min.js">
3. Kopieren Sie den Ordner patterns aus dem Hyphenator Download in ihr Verz.
  /i/Hyphenator/patterns/de.js

4. Definieren des Plugins in ihrem APEX HTML Header

<!-- START: Hyphenator Plugin -->
<style type="text/css">
.hyph {
/* WIDTH Parameter wird erst ueber Spalte definiert */
display:block;
/* DISPLAY:BLOCK ist immer zwingend erforderlich */
overflow:hidden; float:left;
/* Schneidet alles Sichtbare über der max. Groesse ab, dadurch entstehen keine Fehler beim verkleinern, IE6 Fehlverhalten */
white-space:normal;
/* Darf niemals: white-space:nowrap als Einstellung in einer Tabelle haben */
word-wrap: break-word;z-index:999;
/* Fuer IE6 */
}
</style>
<script type="text/javascript" src="/i/Hyphenator/Hyphenator.js"></script>
<script type="text/javascript" src="/i/Hyphenator/jquery.hyphenator.min.js"></script>
<!-- ENDE: Hyphenator Plugin -->

5. Deaktivieren Sie in ihrem APEX Report Template folgenden CSS Einstellung
  white-space:nowrap mit white-space:normal;

<!-- Column Heading Template -->
<th ... style="white-space:normal;z-index:999;word-wrap: break-word;"> </th>

<!-- Column Template 1 -->
<td ... style="white-space:normal;z-index:999;word-wrap: break-word;">#COLUMN_VALUE#</td>

6. Report Spalten Anpassen

<!-- Column Heading: -->
<span class="hyph" style="width:50px;text-decoration: underline;">Anwendungsname</span>

<!-- HTML Expression -->
<span class="hyph" style="width:50px;">#NAME#</span>

Info: Hier definieren Sie die maximale Breite und die Option Hyphenation zu verwenden.

7. APEX Dynamic Action für Report anlegen

After Report Refresh Trigger mit javascript Ausführung: $('.hyph').hyphenate();
Im Idealfall sollte sollte ein ähnlicher Report wie in meiner Beispielanwendung herauskommen:
http://ta-it-consulting.de/hyphenation.html

Info 1: Die LANG Option im HTML Tag definiert die Übersetzungssprache <html lang="de">
Info 2: Das Plugin kann auch in APEX 3.2 verwendet werden, außerdem ist der IE6 ohne Probleme verwendbar.

Das Ergebnis ist eine universelle Lösung die all ihre Reportprobleme lösen könnte.

Der einzige Haken ist eine erhöhte CPU Auslastung auf der Clientebene. Also Vorsicht vor verschwenderischer Übersetzung.

Mal was anderes: Inzwischen ist auch der AAW-DBMON ONLINE: http://ta-it-consulting.de/dbmon.html

Jest pierwsza poprawiona wersja APEX-a 4.0

Apex dbe pl 19-AUG-2010 15:59

Od wczoraj można pobierać APEX 4.01. Wersja ta poprawia sporą ilość wykrytych błędów. Szczegółowe informacje o poprawkach znajdują się tutaj.
Jeżeli ktoś wcześniej instalował wersję 4.0 i używa Oracle XE to w pierwszej kolejności musi obniżyć wersję do APEX 3.2 a następnie zainstalować najnowszą wersję APEX-a. Tak samo należy postąpić jeżeli nie ma się dostępu do Metalinku (patchsety).
