I'm currently writing a REST Web Service presentation for the Australian Oracle User Group, and thought it would be useful to document in 10 quick steps how to enable REST Web Services in Oracle's JDeveloper using the Jersey implementation of JAX-RS (JSR311). This is documented in Oracle's online documentation, but that's never stopped me writing a blog entry before in my usual succinct manner. Step 1 – Create your Application Workspace – base it on the Generic Application template: ...and let it create the default project with no technologies: ...with this result in the Application Navigator: Step 2 – Download the required Jersey libraries . Note JDev that this blog entry is written in supports Jersey and above. At the time of writing the latest non-beta release was 1.4 and is used as a basis for this blog. From the Jersey download documentation pag... (more)

Retrieving Managed Beans Programmatically

From time to time in JSF and ADF Faces RC applications there’s the need from one managed bean to retrieve another, typically from a lesser scoped bean to a greater, such as a requestScope bean retrieving a sessionScope bean to access its methods. There’s essentially three avenues to solving this problem: 1) The following JSF 1.1 createValueBinding method that retrieves the bean using EL: FacesContext ctx = FacesContext.getCurrentInstance(); Application app = ctx.getApplication(); ValueBinding bind = app.createValueBinding("#{beanName}"); Bean bean = (Bean) bind.getValue(ctx); Note ...

Stress & Load Testing Web Apps (Even ADF & Apex) Using Apache JMeter

A couple of years ago I presented Take a load off! Load testing your Oracle Apex or JDeveloper web applications at OOW and AUSOUG. I can't recommend enough the importance of stress testing your web applications, it's saved my bacon a number of times. Frequently as developers, we develop under a single user (developer) model where concurrency issues are easily avoided. When our programs hit production, with just 1 more user, suddenly our programs grind to a halt or fall over in bizarre places. Result, pie on developers' faces, users' faith in new technologies destroyed, and genera... (more)

SoapUI for Web Service Testing

A popular tool for web service testing is SoapUI. The following blog post describes how to use it for testing a simple web service, as well as setting up a series of tests and even load/stress testing. Without a doubt similar documentation is available on the SoapUI website; my post gives my spin on the product that maybe useful to others. In this post we'll look at: 1) A simple web service example 2) Creating a simple test in SoapUI 3) Creating a test suite 4) Loast/stress testing your web services Our web service The web service we'll use here for testing is a simple Hello World exam...

Upgrading Oracle WebLogic Servers from 10.3 to 10.3.1

Recently we upgraded our Oracle WebLogic Servers from 10.3 to 10.3.1, and coincidentally migrated a JDeveloper ADF application 11g to 11gR1. ADF applications require a set of libraries that must be deployed to WLS before the ADF application can run, of which we completed successfully, or so we thought. This post documents a little trap for new players when configuring WLS and deployed applications. On deploying our upgraded ADF 11gR1 application to our WLS 10.3.1 server with the updated ADF libraries, we hit an error on deployment from JDev. The logs showed the following results:... (more)
