Minor observations on the ADF standards document

Java Tools and Frameworks
| Feb 24, 2013
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.

ADF & Event driven Integration with a BPMN process

Java Tools and Frameworks

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 (more...)

Drilldown on ADF DVT graphs

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]

Java Tools and Frameworks
| Aug 21, 2012
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.

A very important read for ADF/Fusion application design

Java Tools and Frameworks
| Aug 14, 2012

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 -

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

Java Tools and Frameworks
| Aug 14, 2012
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' -

How to show/hide operators in adf:query advanced mode

In this post, I will provide a way to modify the operators list in the ADF query panel (af:query component) - i.e. to remove and add operators to the list.

Simplified J2EE view

Java Tools and Frameworks
| Feb 25, 2012
Entity objects = business domain objects: data + validations - we would traditionally implement these using entity EJB's, hibernate objects etc. 
View Objects = Not exactly J2EE TO's - I find this an abstraction unique to ADF encapsulating the POJO and a query.
Application Module = the API interface (more...)

Getting hold of the http request object (ServletRequest) in ADF

Java Tools and Frameworks
| Feb 11, 2010
Anyhow, this piece of java code can be used to access the http request object, if needed: 
((ServletRequest)ADFContext.getCurrent().getEnvironment().getRequest())
 
Normally, i'm not in favour of jumping through hoops to do things that the framework doesn't provide. If it's a framework shortcoming, by all means, go with (more...)

Something about requestScope.

I should first mention, Frank Nimpihus has an excellent viewlet on "How - to bookmark view activities in a taskflow".
Edit: I started off to address the bit about having a bookmarkable page with parameters using just the requestScope.
I started this intending to get hold of an http request (more...)

Read only View Object should *also* be based on Entities

Java Tools and Frameworks
| Feb 7, 2010
This might involve a wee bit of paradigm shift for developers moving on from 10g. 
The prevailing wisdom in 10g has been to not base read-only view objects on Entities and for good reason: performance gain. 


The recommended approach in the Fusion developer guide, however, is to base (more...)

ADF Sample: Declarative line item search

A common functional requirement is to search for master objects based on some attributes of its detail objects.

- Invoices containing invoice lines with specific item names.
