You can use a servlet filter for managing enitity managers (and transactions)
1. in Filter.init() create the entity manager factory 2. in Filter.destroy() close the factory. 3. create an entity manager on demand (if it is needed) in your code, place it into thread local so that others can refer to it in the same request 4. in Filter.doFilter() close the entity manager after calling chain.doFilter(), but only if the entity manager was created in step 3 -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
