Hi everyone,

I have an app who actually work with a dao layer. This layer as
actually only one Hibernate implementation. I want to make this app
available on Google App Engine.
But I don't want to annotate all my data classes. So I have tried to
write a default Dao who use the Google LowLevel api and the Sun|Oracle
Reflexion api to convert my data classes to entities . He is doing
what I want but fail when a data class contains other data classes. I
have tried to convert the "sub" data class to an entity and persist
but now my dao fail when a property is an Integer because the LowLevel
api return a Long.
Is there an existing DefaultLowLevelDao or something like that or a
may to easilly convert the entity property type to the expected one ?


Thanks
