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...)

Handling Rollback Operation for ADF Input Components with Immediate Property

One of my colleagues is implementing advanced dynamic ADF BC/ADF UI functionality. To force validation to be invoked properly, he must use ADF UI input components set with Immediate=true property. This allows to keep validation messages always displayed, even if user navigates to edit another dynamic ADF UI input attribute, until form is submitted or canceled. However, as by JSF design - usage of input components with Immediate=true, blocks execution of command components, if there (more...)

Test your Application with the WebLogic Maven plugin

In this blogpost I will show you how easy it is to add some unit tests to your application when you use Maven together with the 12.1.3 Oracle software ( like WebLogic , JDeveloper or Eclipse OEPE). To demonstrate this, I will create a RESTful Person Service in JDeveloper 12.1.3 which will use the Maven project layout. We will do the following: Create a Project and Application based on a Maven

Hibernate Statistics with Hawtio and Jolokia

A huge part of enterprise Java deals with data. Among all the different ways of working with data in enterprise settings, there is still the proven and widely taught approach to use O/R mapping of any kind. The JPA standard makes this comparably easy to use for everybody and it should also be portable. But let's not talk about migration details. The biggest drawback of O/R mapping is, that a developer tend to lose contact (more...)

Developing with JAX-RS 2.0 for WebLogic Server 12.1.3

In an earlier post on the topic of Using JAX-RS 2.0 with WebLogic Server 12.1.3, I described that we've utilized the shared-library model to distribute and enable it.

This approach exposes the JAX-RS 2.0 API and enlists the Jersey 2.x implementation on the target server, allowing applications to make use of it as when they are deployed through a library reference in a weblogic deployment descriptor.

The one resulting (more...)

Using Eclipse (OEPE) to Develop Applications using WebSocket and JSON Processing API with WebLogic Server 12.1.3

Following from my last posting, I thought I'd also show how Eclipse (OEPE) makes the new Java EE 7 APIs available from Oracle WebLogic Server 12.1.3.

The first step was downloading and installing the Oracle Enterprise Pack for Eclipse (OEPE) distribution from OTN.

http://www.oracle.com/technetwork/developer-tools/eclipse/downloads/index.html

Firing up Eclipse, the next step is to add a new Server type for Oracle WebLogic Server 12.1.3, pointing at a local installation.

Getting started with SwitchYard 2.0.0.Alpha1 on WildFly 8.1.0.Final

I've been sticking my head into some hot RedHat technologies lately and among the many interesting parts I found SwitchYard. Without being disrespectful towards everybody wrapping their heads around SOA and service oriented architectures in the past, this has always been kind of weird to me as a Java EE developer.

In the past I've been building component oriented applications with what I had at hand. Mostly driven by the features available in the Java (more...)

MDS Support for Mobile Application Framework (MAF) in JDeveloper 12c (12.1.3)

MAF framework in JDeveloper 12c (12.1.3) comes with MDS support. This means, we can customise mobile applications in similar way as we customise regular ADF Web applications. I'm going to explain and demonstrate with sample application, how it works MAF 2.0. You can read about this more in MAF 2.0 developer guide, Customizing MAF AMX Application Feature Artifacts.

Sample application, tested with iOS platform - MAFMobileLocalApp_v2.zip. Original version of this (more...)

Being Right and Proving It

One of the great things about working in IT is that you can often win an argument simply by being right. Not because of who you are or because you are more eloquent than others, but because the facts support your position. Almost every IT person I have ever met respects facts.

In order to win arguments this way, you of course need some facts to work with. And that’s where too many people fail. (more...)
