Apple has released WebObjects 5.1.1. It’s an update to its Mac OS X suite of tools and object-oriented frameworks for building and deploying Web and Java applications.

The application includes updated versions of several WebObjects class and JAR (Java Archive) files. In object-oriented programming, a class defines the methods and variables in a particular object.

The 5.1.1 update contains general bug-fixes for WebObjects 5.1 on all platforms. It’s available through OS X’s Software Update feature, and can also be downloaded from Apple’s Web site. Web Objects 5.0 retails for £493 (plus VAT).
