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 general gnashing of teeth all round. Some simple stress and load tests can head off problems way before they hit production. (For the remainder of this post I'll infer "stress testing" and "load testing" as the same thing, though strictly speaking one tests for your application falling over, and t... (more)

Configuring Apache JMeter for Oracle's ADF 11g

Sometime back I blogged about Stress & load testing web applications (even ADF & Apex) using Apache JMeter. That post dealt with the generic setup of recording a web session and then replaying under load via JMeter. When considering using JMeter for JDeveloper 11g ADF applications there are additional JMeter configuration steps required beyond that detailed in the original post. As per the original post ADF passes around cookies to store the JSESSIONID, and you can use JMeter's HTTP Cookie Manager to correctly handle the cookie. However ADF also makes use of a number of parameters ... (more)

Book Review: Middleware and Cloud Computing

With the explosion of Internet content, especially that for the IT industry, it leaves an interesting question hanging over the worth (if any) of IT textbooks. When you can find an answer on just about anything online, what’s the point of shelling out money, especially for IT texts that have been overpriced for sometime? Frank Munz’s Middleware and Cloud Computing: Oracle on Amazon Web Services and Rackspace Cloud book is a good reminder of one key fact about text books in context of an internet society, they can save you a lot of research and time on the internet looking for th...

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)

One-Way SSL with JAX-WS Using JDeveloper 11gR1 and WLS 10.3.1

A while back Gerard Davison blogged some simple examples of using WS-Security Policies. Gerard's specific example dealt with the WLS policy Wssp1.2-2007-Wss1.1-UsernameToken-Plain-X509-Basic256.xml. As Gerard notes the said policy (further documented in the WLS 10.3.1 doco here) implements user name tokens, encryption of the tokens and signing of the whole SOAP payload. The following post strips back Gerard's example to instead to consider the steps in setting up and testing One-Way SSL for a JAX-WS web service generated via JDeveloper 11gR1 and installed in WLS 10.3.1, using the...
