How to map XML data structure to database with JPA (Java EE)

Question

I'm on a project, where I get XML data like invoices from a service provider. These invoices have many positions with the same structure, like Adress, Service Type, and amount of costs. I need to store this data in seperate datasets in different rows. I got an XML schema file from my provider.

I could unmarshall the XML files to java Objects. Is there a way to insert this data to a database with JPA. the problem is, that the through JAXB generated classes doesn't have annotations like Entity or columns. I could annotate these classes but after a "clean and build" with Netbeans the classes will be generated again without annotations.

Anyone know a way to build classes from XML schema with JAXB, read the incoming XML files, unmarshal this? and write the data to database.

您可以使用Java Bean到Java Bean映射器（如Dozer）将生成的类映射到JPA实体。
