The 2014 Guide to Enterprise Integration is available

DZone made it again. Another one of their famous guides got published yesterday. This time it is all about Enterprise Integration. It contains articles by industry experts and the complete result from a survey of over 500 practitioners and developers which is probably the most interesting part. So, looking at the distribution of the different integration solutions:

"Out of all integration frameworks (EIP), ESBs, and
integration suites, Spring Integration is the most popular (42%) and (more...)

On Java EE and Community – Voxxed Interview

Devoxx is nearly a wrap. Beside the general awesomeness, Stephan and his team launched a new content website to be the number one stop for all topics related to technologies which are relevant for Devoxx attendees. While I've been at GeeCon, Lucy asked me for an interview which I happily gave. So we get to chat about WildFly development and explains why the Java EE needs you. And about  JBUGs (http://www.jboss.org/usergroups) (more...)

Dynamic ADF Buttons Solution for Oracle BPM Outcomes

Did You Know that You Can Buy OUM?

The Oracle Unified Method (OUM) Customer Program has been changed in that, next to the already existing option to get it by involving Oracle Consulting, you now also can buy it if (for some reason) you don't want to involve Consulting.

Next to that there also is the option to purchase a subscription (initial for 3 years, after which it can be renewed annually) allowing to download updates for OUM.

OUM aims at supporting the (more...)

The Future of Oracle ADF

At Oracle OpenWorld, there was a lot of Oracle ADF material. I presented on Oracle ADF Bindings as part of the well-attended ADF track on User Group Sunday, and Oracle also gave some very interesting presentations on new and coming features in ADF. For example there is now an ADF component that you can use to visualize any network of nodes and edges.

But what struck me more was the fact that when Oracle buys (more...)

Trip Report: Joker Conf 2014

I am traveling a lot lately and catching up with the trip reports is not easy. One of my favorite trips lately was my visit in St. Petersburg, Russia for Jokerconf. It is one of the most technical and Java centered conferences I've seen in a while. The session schedule is an endless list of high quality speakers and topics. Given that, I was honored to present about Java EE and JavaScript while the organizers (more...)

What is your "x"? The technical details about the Devoxx Keynote Demo

If everything went fine, I just got off the stage and ended the demo part of Mike's (@mpiech) demo. We talked a lot about xPaaS. The different pieces of the puzzle that we integrated and about our newest acquisition FeedHenry. I think, that all this is worth a more detailed blog post about the inner workings of the demo.

Background
RedHat released a new version of OpenShift Enterprise 2.2 on the 10/10/14. This version (more...)

Dynamic ADF Form Solution for Oracle BPM Process

This worked pretty well, all configuration was done based on my previous blog post for similar topic, only previous ADF and BPM versions - BPM 11g R1 Worklist Integration (Hacking Experiment) Into Non-SOA ADF 11g R2 Domain. Goal of this post is to describe dynamic ADF form approach associated with BPM process human task.

Starting a Pivotal GemFireXD Distributed System from IntelliJ IDEA

The example below shows how you can start a Pivotal GemFireXD distributed system from IntelliJ IDEA. Here we will start a Locator which has Pulse enabled as well as one member. We use the following class method to achieve this from an IDE such as IntelliJ

FabricServiceManager.getFabricLocatorInstance()
FabricServiceManager.getFabricServerInstance()

1. Add the following to your maven POM file to ensure the correct libraries are present.
  
<dependency>
<groupId>com.pivotal.gemfirexd</groupId>
<artifactId>gemfirexd</artifactId>
<version>1.3.0</version>

Missing stack traces for repeated exceptions (reminder)

A long while ago a optimisation was added to the JVM so that if the same exception is thrown again and again and again a single instance of the Exception is created without the stack trace filled in in order to increase performance. This is an excellent idea unless you are trying to diagnose a problem and you have missed the original error.

If you forgot about this optimisation you send the afternoon looking at (more...)

MdsMetadataResourceProvider Error in ADF 11.1.1.7

If you have migrated ADF application to ADF 11.1.1.7 version recently, you may see error in the log related to the internal MetadataResourceXmlImpl class usage. Runtime behaviour will not be affected, but there could be many redundant error messages in the log, like this one:


Error UNEXPECTED_CLIENT_OBJECT_TYPE found oracle.adf.controller.internal.metadata.xml.MetadataResourceXmlImpl, points to the ADF internal class usage, instead of public. You must look through the source code (more...)

An inspiring book from one of the original creators of Scrum. Full of anecdotes about how Scrum saved projects and can be used outside the software industry. Its main purpose is to motivate you to get started using Scrum, but it does contain enough methodology to actually allow you to use the methodology. It (more...)

Work-around Instance Migration Limits of BPM Suite 11g

The following describes a work-around for 2 situations for which instance patching and migration is not supported, being changing the level of an activity, and removal of an embedded sub-process. In short this work-around consists of re-implementation of the activities to move, and emptying the reusable sub-process.

There are a couple of restrictions for the Oracle BPM Suite that can make that process instances cannot be patched (deployment using same revision number) or migrated (deployment (more...)

Creating a WebLogic 12c Data Source Connection to Pivotal GemFireXD 1.3

I am going to show how you would create a WebLogic data source to Pivotal GemFireXD 1.3. In this example I am using the developer edition of Weblogic which known as "Free Oracle WebLogic Server 12c (12.1.3) Zip Distribution and Installers for Developers" You can download / configure it as follows.

Handling Date Format and ADF Bindings

There are tips and tricks related to the date format handling and ADF bindings. When Oracle date type attribute is being used through ADF binding expression, it will be converted to String with default format (yyyy-MM-dd), no matter what original format was set. This is described in API for the Oracle date type - Date constructor with String. Below I'm going to explain how it works and how you could optimise ADF application to handle (more...)

Dead Code Kills

Your applications contain 20-30% dead code that is never executed. Not just commented-out code that programmers have left in “just in case”, but routines never called, branches never executed and screens never displayed.

The cost of software maintenance depends on the size of the code base, but systems with dead code are more expensive to maintain. This is because every time a developer comes across a dead piece of code, he becomes unsure: “I wonder (more...)
