I'm trying to use JBoss Cache in a project. I find <s:cache> tag extremely useful, however I cannot figure out how it's two attributes: region & key are mapped to JBoss Cache's nodes. In particular I would like to take advantage of the tree structure of the cache (to invalidate only a given sub-tree) - is that possible with <s:cache>? I tried to supply /node/path strings to region attribute but not with much luck... Thanks in advance for any help.
