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 WLS policy Wssp1.2-2007-Https.xml. Assumptions This article assumes the reader has the following basic knowledge: * HTTPS/SSL * Digital certificates and trusted/certificate authorities (CAs) * Oracle's WebLogic Server, WLS managed servers and the WLS console One-Way SSL vs Two-Way SSL For those n...

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)

Q&A With Grant Ronald

(This is a reprint of an article published in the UKOUG's Select magazine early this year) When talking about Oracle Forms and JDeveloper, one Oracle personality stands out among others - long time blogger Grant Ronald from Oracle Corporation UK. Grant has for a long time “pimped” Oracle Forms and its big brother JDeveloper at Oracle events and user groups events around the world. His popularity is shown by his blog receiving on average 2000 hits per day. Lately, to reassure Oracle customers that Oracle intends to keep on supporting Oracle Forms and show that Forms has a future i... (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...
