Progress with the Oracle Integration Cloud Adapter SDK

In the past few days, I have been making some progress with using the ICS Cloud Adapter SDK. 
Today, I created my first shell adapter - the design time views can be seen below!

The journey so far: 
 * Reading through the documentation [Ongoing]
 * Developing the empty adapter and deploying it for design time and runtime [Check]

There are a number of integration use-cases that (more...)

WS Security – enabling passwordDigest authentication in an Oracle FMW environment

To have a basic level of authentication on web services (especially where there's no transport layer security) without having to pass clear text passwords in the WS Security headers. 

The concepts are fairly generic but this post is highly Oracle Fusion middleware specific. There can be complex decision tree (see [1]) involved when selecting the 'appropriate' level of security for any system. As security involves trade-offs between cost, performance, usability (more...)

Managing shared metadata (MDS) in a CI enviornment

Goals and Summary:
* Package shared metadata in a SOA environment and make it widely distributable (SOA MDS [2], Servicebus, maven artifact repository) 
* Associated sample:  
* Key command (if you use the associated pom file) 
mvn deploy -Dpassword=*****

Having worked on a wide range of projects, I came to the realisation that SOA can mean vastly different things in different (more...)

Easy SOA releases with JGitFlow

If you use GIT as your source control system and if you use maven, the jgit-flow plugin is a massive time-saver, especially when we release a slightly large application with multiple modules (Each with it's own pom file). 

Two steps: 
 mvn external.atlassian.jgitflow:jgitflow-maven-plug in:release-start
 mvn external.atlassian.jgitflow:jgitflow-maven-plug in:release-start

do the job. 

The above sequence basically updates the pom file versions to a release version (e.g. from 1. (more...)

Test Driven SOA – citrus for powerful SOA test coverage

Reading parts of Test-Driven Development for Embedded C" by James W. Grenning inspired me to take another look at this area and look for something new,  fresh and powerful.

I don't think we need much convincing on the importance of  automated test coverage (if someone does, please read the first chapter of the book mentioned above, especially the section on "Physics of TDD" that tries to quantify the high long-term costs of "Debug later programming" (more...)

Maven builds for SOA Composites with BPEL Java embedding and Java class

Enviornment: Oracle SOA Suite 12.2.1

Sample Application:
(Git clone or use the download option from here: )

 A BPEL component has a Java embedding that in turn calls a Java class method (under the usual SCA-INF/src)

This works and builds find using JDeveloper, but the oracle-soa-plugin for maven seems to have a few known issues (see references for one of them) that cause builds for (more...)

#AMIS25 and The Oracle Cloud Shift : Insights from my first Holland trip

I would like to take this opportunity to wish AMIS Netherlands a very happy 25th birthday. In the context of Oracle SOA, the the name AMIS often keeps popping up - they have contributed a lot to the knowledge available to the community around this and related Oracle technology. 

As they chose to celebrate this occasion in a uniquely signature style - by holding a global Oracle conference with an impressive lineup of speakers (more...)

My first take on SOA/BPM Suite 12c.

The Oracle Fusion Middleware circles have been abuzz this weekend with the launch of the latest and greatest release of BPM/SOA Suite 12c.

The 12c release announcement late Friday evening (GMT+1, UK time)  caught me pleasantly off guard as during the past 6 months I have been very focused on a client project.

Listing below are just a few of my initial notes on the features that caught my attention.

- Experience with initial installation

ADF UI with MongoDB for persistence

The sample application (JDeveloper 12c / 12.1.2) can be downloaded from here.
This is a simple ADF application whose underlying business service implementation uses MongoDB for persistence.
The application allows create & update operations on a one-to-many data model (Department-Employees)

As shown in the screenshot below, you can (more...)

Webservice interaction patterns – part 2 – Synchronous Webservice call timeouts

Goal: For reasons of performance and more importantly, good user experience, he client application (ADF) should be able to timeout gracefully instead of hanging indefinitely (and/or potentially causing STUCK threads on the ADF server) when invoking an external 'synchronous' web service.

At runtime
When I run the application,
If I (more...)

Webservice interaction patterns – part 1 – very basic DML

There are a number of ways you 'call' web services from an ADF application. The best method to choose would depend on the individual scenario.

This particular example is the most suitable option where:
- Our application is allowed to read from the database using its own business services - (more...)

JDeveloper Productivity features – run current working set

In a well designed application ('the sum of parts'), we probably divide functionality into projects. 
At any given time individual developers normally work on one or two projects, which they need to run and test quickly using the integrated weblogic server. 
I find the working set feature very (more...)

Minor observations on the ADF standards document

My original title to this post was: "Entity/Entities, Key abstractions and nouns". 

Just noticed this very useful document on "ADF naming and project layout guidelines" published recently. It represents a valuable and exhaustive resource that many projects and programmers (including myself) benefit from. 

I'm a fan of (more...)

ADF & Event driven Integration with a BPMN process

The usecase for my sample application is:
A standalone application exists to create/update 'Departments'. Originally, it was not intended to be part of an automated process (BPEL or BPMN) but now business decided that their process for the creation of a department is actually more than just data entry in the standalone application. It also now involves an approval. 

1. Every interaction with a software application in a business environment is part (more...)

Brief note on ADF 11gR2 installation

The certified application server and ADF combinations for ADF 11.1.2.x.x are available here.

We need to follow the 

Drilldown on ADF DVT graphs

The sample workspace  (JDev/ADF for this post is available here.
Just run adfc-config from the ViewController project. 

One form of drilldown is where you provide an 'action' that can be a control flow case in the taskflow and which leads the user to another (more...)

ADF and Coloured tooltips – 2 [and its limitations]

Reference: I have simply incorporated the approach presented here in my ADF application and the solution involves a bit of JQuery

This post follows on my earlier sneak peek but as I eventually learnt, this is quite limited in use and you might need to find specific uses (more...)

ADF unbound – multi coloured tooltips anyone?

Please read through part 2 as well as this has some limitations.

This was a client request (can we make it prettier please?) that I originally thought wasn't worth pursuing as it wasn't 'out of the box' and couldn't think of an elegant way.

But then after a beer (more...)

A very important read for ADF/Fusion application design

I think Fusion applications design patterns (i.e. 'FUNCTIONAL' design patterns) are one of the most important resource to become publicly available as a result of Fusion apps development -

(They have been available in beta form for a while now and I made it a point (more...)

The "Is it quick?" methodololgy. Worth it?

The biggest lesson I learnt on Oracle Fusion applications development was the importance of a well engineered product (no-brainer, isn't it?) 

This post recaps why you need a system that is well designed rather than just 'quick' -
