I would start by looking at hibernate4gwt, if only because of the concise information it's documentation gives about integrating GWT with Hibernate and various options. It is based on GWR RPC which I would think that is your probably best option - it is very neat. http://hibernate4gwt.sourceforge.net/ In considering your options I would head straight for information around the central problem of serving Hibernate managed domain classes to GWT: Hibernate classes are adorned with proxies and "magic collections" to deal with lazy loading and this makes them incompatible with GWT JRE emulation. Hibernate4gwt automatically translates Hibernate managed classes into GWT friendly DTO versions for transport to client, and restores and updates them on return for you. Whatever you do, you have to deal with this problem, and I would say that you designed your own solution it would probably look very like hibernate4gwt in the end. > > 2.

Another good reason to use GWT RPC if you are using Spring. There are plenty of tutorials and articles about how to integrate GWT with Spring - google "spring GWT inegration" regards gregor > Any help will be highly appreciated > Regards > amol --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
