Running Webservices using APEX on XE

Just fiddling around with my ApEx (2.2) installation on XE I tried to add a Webservice. So I used the Web Service wizard and choose Yes in "Search the UDDI registry" and clicked Next. In the next screen I selected (the only available) "xMethods UDDI v2" and clicked Next. The I searched for "stock". The next screen showed "ORA-20001: The webservice was unreachable because either the URL you supplied was invalid, or your environment requires a valid proxy server address for HTTP requests.". So I added the proxy server under the Application Attributes Definitions and followed the same steps as above. The search for "stock" returns "ORA-20001: The response from the UDDI registry was invalid." this time. Looking at the Apex and XE forums didn't return any valuable hits. The I switched (from FireFox) to IE. This time the error told me something more: "the proxy server required authentication", so I added my username and password to the proxy server definition (http://<username>:<password>@<proxy>:<port>). But that still didn't solve the problem. Because my company has a strict password policy I had chosen a password with an "@" in it. After changing my password in something else and changing this also in the proxy server definition....it worked!

So with some trying-and-error I finally succeeded in using webservices in XE!

So I hope this little blog can save you some time figuring out the same...

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…

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 Application only. And if you had a lot of files - e.g. a lot of images - then you had to go through the upload process one-by-one. But that's usually a one time only thing. If you make changes to the CSS and JavaScript files - and that's a continuous process in development - then you had to delete the existing file and upload the new one. Over and over again. And meanwhile fighting the cache of the webserver and your browser.  And another irritating issue: You couldn't use relative references in your CSS or JavaScript files as they just…
