RMOUG 2010 – February 17 – 18, 2010

Sunday, October 25th, 2009

I will be presenting a fun session titled, “ApEx – From the Garage to the Basement”. This session will discuss how entrepreneurs can build a working environment for ApEx development in their basement with an old PC and Internet connection. In the past where companies like HP started in the garage; today, we have developers creating applications using a PC tucked away in the basement.

Hopefully, this presentation will be a fun time for all. Hope to see you there!

Using JSTL Exception Handling in JDev 10.1.2 Portlet

Friday, June 19th, 2009

The following is a portlet I recently updated for Oracle Portal. The dates were not formatting properly, so I added a JSTL catch tag. This also uses choice tags which help when you need an else tag after an if tag.

<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt"%>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>
<%@ taglib uri="http://xmlns.oracle.com/adf/ui/jsp/adftags" prefix="adf"%>

Hello world!

Welcome to my new blog.  My server crashed a second time, and this time the virtual machine was not recoverable.  I will post new information about Oracle UCM and Oracle WCI as I have time.  Please enjoy your visit!
