Release Notes

(1st Mai 2007 - by Lars Torunski)

New features and enhancements

Furthermore the next major release 2.4 enhances the CacheFilter and allows a better integration with the Spring Framework and JMX Monitoring.

• Setting CacheFilter parameters runtime
• Lazy initialization in CacheFilter in order to ease spring integration
• Allow disabling cacheing for special http methods (e.g. POST/DELETE/PUT) in CacheFilter
• CacheFilter allow reentrance over different filter configurations

• Hibernate 3.2 integration support
• JMX Monitoring/Administration via Spring
• Improve oscache.properties loading
• Performance improvment for large disk persistence usage

Upgrade Guide

• Due to the enhancements in the CacheFilter and method signature changes, it's recommended to recompile your code.
• Due to changes for CACHE-284 the handling of the listeners have been changed: Before OSCache 2.4 objects which implemented different CacheEventListener (e.g. CacheEntryEventListener and CacheMapAccessEventListener) had to be added twice, because the listeners where registrated only for one special event listener. With OSCache 2.4 only the object has to be added to the list without the 2nd parameter 'type of the listener'.
