I am planning on creating a standard JBI component for ehcache so that one can easily deploy ehcache endpoints into ServiceMix and other JBI compliant containers. Here are some high level requirements that I think would be useful for this component. Please respond to this thread with any comments are concerns.
Cool :)
1) There should be a way to configure endpoints that when deployed create actual Caches. The endpoints should be able to have expressions associated with them that can determine how the Cache matches information based off of the Normalized Message. So for example, if you have properties that need to be a part of your key in the cache then you can use an expression to match that. If there is an XPath expression that needs to be matched, this can also be used.
The use of an expression is good. This is the way it was done for the lightweight one and should be flexible enough.
2) I'm still not sure whether it makes sense to allow for a SU to configure the CacheManager itself using the ehcache.xml configuration file. The benefit of this is that you leave the component to just worrying about configuration files and not starting up any cachemanagers itself. You will also be able to create specialized cachemanager's with their associated information on the fly. I could see this as being beneficial. However, perhaps it's better to leave the Ehcache configuration specific to the component itself. That is to say that when you deploy the component it loads up its already packaged ehcache.xml file which configures the CacheManager. If someone needs a different configuration they will have to edit the one packaged with the component or go to JMX and update the values stored there.
I think both the configuration on the component, which would provide an easy way to get started, and the configuration on the SU are necessary. Maybe we could reuse spring EHCache support (see http://www.springframework.org/docs/api/org/springframework/cache/ehcache/package-summary.html) but I'm not sure if it will be really helpful for implementing this component as I haven't really looked at it yet.
