Resolving deployment issues with Service Bus 12c – OSB-398016 – Error loading WSDL
Fri, 01 Aug 2014 14:20:16 +0000

I was completely stuck with Service Bus 12c project deployment from JDeveloper to the Service Bus run time. Every deployment met with the same fate: Conflicts found during publish – OSB-398016, Error loading the WSDL from the repository:  The WSDL is not semantically valid: Failed to read wsdl file from url due to — java.net.MalformedURLException:

Rapid creation of Virtual Machine(s) for SOA Suite 12.1.3 server run time environment – leveraging Vagrant, Puppet and Biemond
Thu, 31 Jul 2014 06:58:52 +0000

In recent previous articles I have discussed the use of Vagrant and Puppet for the automated creation of Virtual Machines, for example with various Oracle software components completely installed into them. In this article, I am merely the consumer of goodies. Edwin Biemond published on GitHub the complete set of Vagrant and Puppet configuration files

Fastest way to a Virtual Machine with JDeveloper 12.1.3 and Oracle Database XE 11gR2 – on Ubuntu Linux 64 bit
Tue, 29 Jul 2014 13:46:43 +0000

In a previous article I have explained in quite a bit of detail how to create the Vagrant and Puppet scripts for stamping out a Virtual Box VM with Oracle Database XE 11gR2 and JDeveloper 12.1.3 (with ADF 12.1.3) on top of Ubuntu (64bit Linux): http://technology.amis.nl/2014/07/29/creating-automated-jdeveloper-12-1-3-oracle-xe-11gr2-environment-provisioning-using-vagrant-and-puppet/.

Creating automated JDeveloper 12.1.3 & Oracle XE 11gR2 environment provisioning – using Vagrant and Puppet
Tue, 29 Jul 2014 08:03:28 +0000

Standing on the shoulders of many smart and persistent friends, peers and colleagues, I was able to fairly quickly concoct the Vagrant and Puppet configuration that allows automated provisioning of a VirtualBox VM that runs Ubuntu (64bit Linux) with Oracle Database XE 11gR2 and JDeveloper 12.1.3 (with ADF 12.1.3). With a few command line actions,

ADF Performance Monitor: Measuring Slow Network Time
Sun, 20 Jul 2014 22:37:15 +0000

Recently I was implementing the ADF Performance Monitor at a customer site and doing a detailed performance analysis. This customer had severe (and less severe) performance problems but was unable to pinpoint the exact pain points. Frequently, end-users were complaining because they were experiencing first a very good performance (response times less than a second), and then suddenly

During the last two weeks I have had the opportunity to work on a proof of concept that uses the Google Glass. In this post I will share my experiences with this device from a developers perspective. Probably everyone has heard about the Google Glass, a wearable computer developed by Google X. The Google Glass
