The Core Developers Network has published a review of the good, the bad and the ugly of the soon to be final 2.4 servlet specification produced by JSR 154.
The aims of JSR 154 were some modest feature enhancements, improved deployment descriptors and general clarifications of existing functionality. These aims, with some notable exceptions have largely been met.
This article reviews the most important additions, changes, omissions and remaining problems in the specification. The key new features are introduced and some explanations are given for those that are missing in action. Problem areas that remain in the specification and those that have newly been added are also discussed.
Some of the features listed in the aims of JSR-154 and that have been much requested by users, did not make it into the 2.4 specification. Mostly this was because they proved to be beyond the scope of a point release.
- Programmatic Authentication
- Extensible Deployment Descriptors
- NIO Support
- SingleThreadModel Deprecated
