I'm not a fan of exposing locking behaviour so explicitly. Internally, a sequence of calls like: | tx.begin(); | cache.put("/session/123"); | cache.put("/session/123/abc") | cache.put("/session/123/xyz") | tx.commit(); | should result in a single distributed WL obtained during the first put and released at commit. I guess your reasoning is how do you deal with this if you don't want to use txs? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027311#...
