Top Stories by Chris Muir

As software applications grow, a common technique to reduce the complexity is to break the overall solution into separately built and deployed modules. This allows each component to be worked on independently without being overwhelmed with detail, though the cost of reassembling and building the application is the trade off for the added flexibility. When modules become reusable across applications the reassembly and build problem is exasperated and it becomes essential to track which version of each module is required against each application. Such problems can be reduced by the introduction of dependency management tools. In the Java world there are a few well-known tools for dependency management including Apache Ivy and Apache Maven. Strictly speaking Ivy is just a dependency management tool which integrates with Apache Ant, while Maven is a set of tools of whe... (more)

REA Is Where RIA Becomes the Norm

Oracle on Ulitzer Do you believe that the day when programmers could focus on one language in their jobs is gone? Thanks to the ever-changing IT landscape and the uncertain financial times, contemporary developers are expected to work with a wide range of platforms, frameworks, languages as essentially "masters of all and specialists in none." You need your IDE to move with the times too, moving beyond the simple compiler and debugger to solve the challenges that contemporary developers face. Oracle JDeveloper is such an IDE. From a fledging Java IDE over 10 years ago, today JDe... (more)

ADF Faces RC – displaying user help

ADF Faces RC under JDeveloper 11g supports different mechanisms for displaying runtime help to users linked with an on-screen component. I had a chance to play with this today and (once again) thought I'd document my findings here as I found the Oracle documentation somewhat confusing (or maybe it's just me). The Oracle documentation that describes how to get this working can be found in section 16.5 Displaying Help for Components of the Oracle JDev 11g Fusion Web Developer's Guide. It's worth noting you should read the entire section 16 Displaying Tips, Messages, and Help as the... (more)

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...
