[jboss-user] [JBossCache] - Data integrity in a clustered jboss cache

Hello, Im' using JBoss Cache (tree cache) in a cluster environment. I try to do the following tings : 1. get a value from the cache = get(Fqn, key) 2. modify this value 3. put the value in cache = put(Fqn, key, value) I use SERIALIZABLE isolation level and PESSIMISTIC lock. The problem is when two programs running on differents servers modify the value at the same time. | Server 1 Server 2 | x = getvalue(); | x++ x =getValue(); | put x in cache x++ | put xin cache | If the value was bound to 0, it should be 2 at the end (serializable) but x=1 at the end of the execution. The questions are : - How could I serialize an operation in a clustered cache (ie reading/modify/persist a value in cache) ? I try to manage the transaction myself with transaction manager but it doesn't work. - I also understood from documentation that SERIALIZABLE isolation level lock the node when you read or write value in the cache. I am using jboss cache in a spring context and no transaction attributes are defined. In this case, when the transaction is initialized/commited if I use SERIALIZABLE is used ? - Is it possible to use spring to declare a cache transaction on classes' method ? Thanks a lot.
