Bootstrapping Apache Camel in Java EE7 with WildFly 8

Since Camel version 2.10 there is support for CDI (JSR-299) and DI (JSR-330). This offers new opportunities to develop and deploy Apache Camel projects in Java EE  containers but also in standalone Java SE or CDI containers. Time to try it out and get familiar with it.

What exactly is Camel?
Camel is an integration framework. Some like to call it ESB-lite. But in the end, it is a very developer and component focused (more...)

End-To-End ADF Cloud Deployment Process

ADF and ADF BC perfectly runs on Oracle Java Cloud. You could deploy regular ADF application straight away from familiar JDeveloper environment without any hassle. With this blog post I would like to walk through the process of migrating DB model to the cloud and deploying ADF application (enabled with ADF Security) to the cloud.

Here you can download sample application - TreeComponentsCloud.zip. This application is deployed and runs on Oracle Java Cloud, accessible (more...)

Useless Documentation

Not all documentation is created equal. Too much time is spent on formal design documents that are immediately outdated, and too little is spent on writing code comments.

Useless DocumentationMake sure your process requires and rewards good code comments. And make sure your architecture diagrams are kept up-to-date.

Transactional Data Caching for ADF Mobile MAF Application

I have described basic idea for data caching in ADF Mobile MAF application in my previous post - Data Caching Implementation for ADF Mobile MAF Application. Today I would like to extend similar solution to handle transactional data caching. Sample application displays list of tasks, user can update task status and description. These updates will be saved locally, until the next synchronisation time with the server.

Updated sample application with MAF mobile and server side (more...)

Accessing ADF Iterator Binding from Value Change Listener

This is a quick hint about how to access ADF iterator binding from value change listener method. Let's say you have generic value change listener, reusable with any kind of input components and you want to get information about underlying ADF BC View Object structure in that listener. Value Change Listener provides access to UI Component, we should evaluate component expression and look up in the bindings for component binding name.

Here is the sample (more...)

Dept/Emp POJO’s with sample data for Pivotal GemFire

I constantly blog about using DEPARTMENT/EMPLOYEE POJO'S with sample data. Here is how to create a file with data to load into GemFire to give you that sample set.

Note: You would need to create POJO'S for Department/Empployee objects that have getter/setter for the attributes mentioned below.

Dept Data

put --key=10 --value=('deptno':10,'name':'ACCOUNTING') --value-class=pivotal.au.se.deptemp.beans.Department --region=departments;
put --key=20 --value=('deptno':20,'name':'RESEARCH') --value-class=pivotal.au.se.deptemp.beans.Department --region=departments;
put --key=30 --value=('deptno':30,'name':'SALES') --value-class=pivotal.au.se. (more...)

Data Caching Implementation for ADF Mobile MAF Application

If you are building mobile application with web service call integration, you must take into account data caching strategy. Without data caching, mobile application will try to establish too many connections with the server - this will use a lot of bandwidth and slow down mobile application performance. This post will be focused around the scenario of implementing simple data caching strategy. In my next post, I'm planning to review MAF persistence framework from Steven (more...)

Java Champions at JavaOne 2014

Isn't it that time of the year again? Booking hotels and travels. Most of my fellow Java Champions (and former ACE Director fellows) are doing some kind of preparation for JavaOne and Oracle OpenWorld these days. Only a few more weeks to go and the content catalog is published. So I thought I might also spend an hour to look at good content. Let's start with talks given by Java Champions.

The Java Champions are (more...)
