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...)

NetBeans Nightly Now Includes The WildFly Plugin

Good new out there. The recent nightly builds of NetBeans already contain the latest WildFly Plugin. So you don't need to add it manually and can start working with your favorite application server right away.
Try it out and grep the latest nightly build. Please keep in mind, that the nightly builds are developer builds and shouldn't be expected to be stable.

Some first steps to get started:

Are Web Service a Mistake?

Quick, how many different Web Service specifications are there?

  1. less than 20
  2. between 20 and 40
  3. more than 40

I was in doubt whether the answer would be 1) or 2) – after all, there is a lot of WS-* stuff. Turns out the answer is 3) – there are currently 50 web service specifications.

A technology with 50 specifications is unlearnable. The basics of web services is simple and useful, but the IT industry (more...)

Test your WebLogic 12.1.3 enviroment with Robot

Robot Framework is a generic test automation framework which has an easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach. This means we can write our tests in readable and understandable text. If we combine this with the REST Management interface of WebLogic 12.1.3 we are able to test every detail of a WebLogic domain configuration and when we combine this

ADF Thematic Map in ADF 12c (12.1.3)

ADF Thematic Map component from DVT library was updated in ADF 12c with marker zoom option and area layer styling (ADF 12c (12.1.3) new features). I have decided to check how it works and implemented quick sample application - ThematicMapApp.zip.

I was using world GDP data (SQL script is available together with sample application) and displayed it using ADF Thematic Map. World country borders are hidden on purpose, borders are (more...)

Create with WLST a SOA Suite, Service Bus 12.1.3 Domain

When you want to create a 12.1.3 SOA Suite, Service Bus Domain, you have to use the WebLogic config.sh utility.  The 12.1.3 config utility is a big improvement when you compare this to WebLogic 11g. With this I can create some complex cluster configuration without any after configuration. But if you want to automate the domain creation and use it in your own (provisioning) tool/script then you

Learning It All

I was recently advising a transition project where a customer was switching support and maintenance supplier. This means that one organization must take over a system that has been maintained by another organization for a number of years.

A lot of information is lost in these transitions because knowledge of the problem domain has been accumulated in the heads of developers over many years. This loss cannot realistically be mitigated.

But sometimes, specific information about (more...)

Standard ADF BC Passivation/Activation for Transient View Object

If you want to implement transient View Object in ADF BC, you must make sure it will be passivation/activation ready, otherwise you may loose data. There are several ways how to achieve passivation/activation for such View Objects - override passivation/activation lifecycle and handle transient View Object rows programmatically or reinitialise transient View Object rows from Application Module prepareSession method. There is one more solution, I'm going to describe it in this post. It is based (more...)
