Thank you. We were tired of writing boring code over and over again.

Each request always have a new Hibernate session associated. All the Hibernate-related logic is performed only inside this session. We tried a lot of various approaches for Hibernate integration and have found out that the best way (and the simplest one) was to never store references to persistent objects keeping their IDs instead. Having the ID we always can reload the object in the current session. The same is true for objects stored in the HTTP session (for instance, ShoppingCart). Many current approaches to state saving favor HTTP session over request. But writing applications we try to avoid storing data in HTTP session due to many issues that arise in this case. I won't get into details here because I'm sure every developer is perfectly aware of them. To pass an object via a request we must be able to assosiate the object with a string ID that can be used to restore the object on a target page. This is pretty easy for many built-in types (numbers, strings, dates etc). Such an approach can be easily extended any object assuming that there's a unique ID representing the object. For instance, persistent objects can be represented as Object Type + Hibernate ID. If the objec t is not supported by Rumba we have to resort to HTTP session. Taking into account all the above Rumba can associate an object with ordinary <h:outputLink> which is very useful for "edit links". For forms that get submitted we use JSF state saving but always encode objects into IDs to avoid any possible issues with persistent objects. I'm sure it is nothing new, just a common pattern built into a reusable framework. > > regards, > > Martin > > On 3/31/06, Werner Punz <[EMAIL PROTECTED]> wrote: > > Alxeij great... > > > > I think your way is the way to go, moving over > > to the next level. > > God knows why almost every week the next framework > pops > > up which still messes around on servlet jsp level > > instead of trying to add value to one of the > existing frameworks. > > Great stuff. > > > > > > > > Werner > > > > Alexey Maslov schrieb: > > > Hi, > > > > > > I want to introduce a new framework and I'm a > bit > > > afraid of it.
