The following demo shows how to use the PCF 1.2 PHD service with HAWQ by loading data into the PCF PaaS platform.
1. First lets setup our ENV to use the correct version of HADOOP on our local laptop.export HADOOP_INSTALL=/Users/papicella/vmware/software/hadoop/hadoop-2.0.5-alphaexport JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
export PATH=$PATH:$HADOOP_INSTALL/bin:$HADOOP_INSTALL/sbinexport HADOOP_OPTS="$HADOOP_OPTS -Djava.net.preferIPv4Stack=true"
export HADOOP_OPTS="$HADOOP_OPTS -Djava.awt.headless=true -Djava.security.krb5.realm=-Djava.security.krb5.kdc="
export YARN_OPTS="$YARN_OPTS -Djava.security.krb5.realm=OX.AC.UK -Djava. (more...)
One of the great things about working in IT is that you can often win an argument simply by being right. Not because of who you are or because you are more eloquent than others, but because the facts support your position. Almost every IT person I have ever met respects facts.
In order to win arguments this way, you of course need some facts to work with. And that’s where too many people fail. (more...)
Tree bindings can be very handy, for example to combine details in the same row as the master. Let’s assume we have the following starting point based on the HR schema:
We see the department in a form layout with navigation buttons, with a table under the form showing information about the employees. As you can see in the screenshot below in the ApplicationModule, there is also a Jobs detail under the EmployeeView.
If you (more...)
Default method’s (aka Defender methods) in interfaces are new in Java 8. They enable you to define a default implementation of a method in the interface itself.
If an interface is implemented by several classes, it’s hard to add method’s afterwards, as it will break the code and require all implementing classes to define the method as well. Adding a method to the interface, and defining a default implementation for it, will resolve this problem.

Today we are extremely happy to announce an all new AeroGear UnifiedPush Server!
The UnifiedPush Server comes with a completely rewritten Angular.js based UI and is now powered by Keycloak! Thanks to the Keycloak team for the great work they delivered helping the AeroGear team to make the Keycloak integration happen.
Getting started w/ the new server is still very simple:
I wanted to install Oracle JDevelper 12.1.3 – a version that I had been eagerly awaiting. Since my primary machine is a MacBook, I wanted to install it on OS X 10.9.3.
I downloaded the generic installer and found that the install didn’t run. Since OS X had disappeared from the documentation, I assumed that I would have to fiddle around until I found a combination of JDK and OS (more...)
.. and thank you for amazing 14 years. It's true: I've been within the msg group for an incredibly long time and have been working in the Java/Java EE space almost all of it. Next Friday (07/11/14) will be my last day. Now it is time to move on.
I've been working with customers and internal Java EE projects all over the place, blogged, authored articles and have been speaking at conferences a lot. The passion (more...)
Each year at the annual Oracle ACE Director briefing, I look around at the laptops my fellow ACE Directors are carrying. More and more of them are MacBooks – I think we were up to around 50% last year.
That makes it all the more puzzling that the installation guide for the latest version of Oracle JDeveloper (12.1.3) does not mention OS X installs at all. The 12.1.2 version had sections (more...)
With the 12.1.3 release of Oracle Service Bus and Oracle SOA Suite we finally can build all our soa projects with Maven. And this time we can do it natively without calling a utility like configjar or ANT from Maven .
We start by setting all the required variables like JAVA_HOME,M2_HOME and PATH
