ADF Faces 12c Components Demo and Test Automation

You might have noticed that I am working on a series of blog articles on using Selenium to automate testing of Oracle ADF applications. This includes work on a little framework to make this easier and a set of sample JUnit tests against the public Oracle ADF Faces 12c Components Demo.

Getting the Faces 12c Component Demo running with test automation had some challenges. I wanted to write them down here in case somebody wants (more...)

ADFLogger 12.1.3 ignoring message parameters and resource keys

In JDeveloper 12.1.3 Oracle made a switch to a new log formatter that has its shortcomings. It no longer knows how to replace resource bundle keys with their actual message and also fails to replace the {0}, {1}, ... placeholders with their actual values. You can end up with logging looking like this:
<oracle.adf.view> <RichRenderKit> <isAutomationEnabled> <AUTOMATION_ENABLED_WITHOUT_AUTOMATION_JAR> 
<oracle.adf.common> <ADFConfigFactory> <findOrCreateADFConfig> <Resource {0} not found on the classpath.>

Waiting for ADF Partial Page Rendering in Selenium tests

One of the main reasons people fail to use Selenium (or any other tool) for automated web testing with Oracle ADF is timing issues. The test automation tool typically wants to execute its actions as quickly as possible. This can be a challenge in dynamic applications that load parts of the pages on demand or in response to user interactions. This is what ADF typically does with partial page rendering requests.

For example, the test (more...)

Configuring an ADF Project for Selenium testing

Running Selenium testing against an ADF application requires direct interaction with the HTML DOM, JavaScript and CSS. An ADF application is normally optimised for performance and scalability which means CSS classes and javascript are minified and obfuscated. This makes testing with Selenium very difficult and brittle.

Fortunately you can configure quite a few settings in your project's web.xml file to make it more development friendly. I've written about these before but some are even (more...)

Testing ADF with Selenium WebDriver Page Objects

Selenium is an awesome (and free) tool to automate browser-based user interface testing. Selenium offers two ways of working; Selenium IDE; a firefox add-on for simple record-and-playback of interactions with your browser and Selenium WebDriver; a collection of language specific bindings to drive a browser -- the way it is meant to be driven.

For testing ADF applications you'll need to use Selenium WebDriver as that sends native events to the browser it is controlling. (more...)

showPopupBehavior align property examples

I always struggle to understand the official descriptions for the align attribute of the af:showPopupBehavior tag. A picture is worth a thousands words so I just created screenshots of all the possible values:

afterStart: The popup appears underneath the element with the popup's upper-left corner aligned with the lower-left corner of the element. The left edges of the element and the popup are aligned


afterEnd: The popup appears underneath the element with the (more...)

Host a Soap Web Service on Google App Engine with JAX-WS

We are about to release a great addon for JDeveloper that can access a SOAP web service. For demonstration purposes we want to have a publicly available web service that anyone can use. Having this web service hosted on Google App Engine has two major benefits: it is free and is accessible for anyone on the internet 24x7.

We wanted to implement a simple Java (JAX-WS) webservice on Google App Engine, but unfortunately this is (more...)

Managed Bean changes should mark their ADF Scope dirty in a HA cluster

We're starting development on a new ADF application and the plan is to run this in a high-available weblogic cluster. The documentation clearly states it is the responsibility of the developer to make ADF aware of any changes to managed beans in an ADF scope with a lifespan longer than one request. This means it is up to you to notify ADF of each change in a viewScope or pageFlowScope bean with the following code:
 (more...)

ADFLogger JAX-WS SoapHandler to log request, reponse and faults

Lately I see a lot of ADF projects consuming SOAP web services. This is typically done by creating a JAX-WS Proxy in JDeveloper and invoking this proxy from java beans exposed through the Bean Data Control or through programmatic ADF Business Components. This post will show how to instrument your JAX-WS proxy so it can log the SOAP request, payload and potential fault to an ADFLogger. This can be a very valuable tool during development (more...)

Configuring ADF Faces for development

This post will describe how to configure your ADF Faces project for development through web.xml context parameters as well as enabling debug mode in trinidad-config.xml. It will also show how to override these settings for production deployment with a deployment plan even though the setting in trinidad-config.xml (more...)

JDeveloper Extension To Suppress Warnings

The JDeveloper auditing framework can be a very valuable tool in delivering high quality code. It not only gives you warnings and errors during development, but can also be run from the command-line on a build server. One thing that always annoyed me is the limited possibilities for suppressing individual (more...)

Overriding Entity doDML or prepareForDml Causes Locking Issues

It is not uncommon for people to override the doDML or prepareForDml method in an ADF BC Entity to do some additional work just before posting changes to the database. The official documentation even describes this extension point as being an equivalent to the Oracle Forms Post Processing triggers.
Today (more...)

Vodafone Content Tampering Making Sites Very Slow On Wi-Fi

I've had issues with this blog sometimes being very slow on my iPhone when using Wi-Fi. I finally figured out what is going and it seems like Vodafone (Netherlands) are to blame.

I noticed my browser is trying to download http://1.2.3.50/jsi/flash.php?file=gordon.js&max-age=3600 which never succeeds (more...)

Decimal Comma with Numeric Keypad as ADF Client Behavior

According to wikipedia 24% of the world's population uses a comma as decimal separator, including The Netherlands where I live. This means entering numeric information with the numeric keypad on the keyboard can be challenging. You can only use it to type a decimal point (.) while we need (more...)

Check for postChanges without commit or rollback in ADF BC

It is not uncommon for an ADF application to invoke DBTransactionImpl::postChanges() to perform database DML without invoking commit (or rollback). This is typically done in environments where we also want to invoke PL/SQL logic in the database that already needs to see these pending changes.

The developer should make sure (more...)

JDeveloper installer very small on Mac OS X

I have previously installed JDeveloper 11 on my MacBook Pro running Mac OS X Mountain Lion (10.8). Basically you download the generic installer from Oracle and run:
java -jar jdevstudio11124install.jar

Today I tried it again and the installer does start but with a very small screen only showing the (more...)

Credential Store Framework

Sometimes you have the need for credentials (username/password) in your ADF, or other Fusion Middleware, application. I've seen numerous solutions with property files, web.xml context parameters, deployment plans, etc. Most of these run into problems with SysOps or anyone else worried with security. You don't want these credentials scattered (more...)

Customizing JDeveloper Preferences

I like to tweak some of the preferences in the Tools menu of JDeveloper. I thought I would document them here for my own reference and in case anyone else is interested. I'll try to list all the settings I typically change from their default. These are ordered and grouped (more...)

ADF Faces Client Behavior with Attributes

Last month I posted about the basics of creating custom ClientBehavior in ADF Faces. Now it is time to take the next step and enhance that example with ways to set attributes on the JSP client-behavior tag, pass these on to the client-side javascript implementation and use them in the (more...)

Custom ADF Faces Client Behavior 11.1.1 JSP tag

This post will show how to create your own ADF Faces client behavior JSP tags which makes them suitable for ADF version 11gR1, also known as version 11.1.1, and version 11gR2 (11.1.2) when not using Facelets.

ADF Faces client behavior tags provide declarative solutions to common (more...)
