RE: [Springframework-developer] EHCache support

And while we're at it, (unfortunately I'm not volunteering just yet), it would be nice to develop a set of interfaces in org.springframework.cache that can be implemented by other systems: ehcache, oscache, JCS. JSR 107 spells out what the interface would look like pretty clearly (http://jcp.org/aboutJava/communityprocess/jsr/cacheFS.pdf), but there are no standard implementations of this. Every implementation of the caching system seems to support it loosely, with common methods, but there is not a common interface, so users are always tied to one particular caching product. Spring has provided this kind of common interface for a number of other areas, and caching would be great to add to it. The jcache (jcache.sourceforge.net) project seems to stay closest to the original JSR. -----Original Message----- From: spr...@li...
