I’ve got alot of beans with attributes, which are derived from database tables with JPA. The users shall be able to enter any column name and a value as a string, and the app shall automatically find the correct member in the one of the beans.

I must use JPA, otherwise I would use some JDBC meta data to put all columns and values into a normal map. Is something like this possible with JPA? It only has to work from database to beans, I don’t want to persist changes.

If this doesn’t work, can I somehow analyze member names programmatically at runtime?

    The EntityManagerFactory has a getMetamodel() method, which returns its MetaModel. From this MetaModel, you may ask for the MetaModel of every entity class, and discover all its attributes, their types, etc.
