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

Question

I am in a project where I receive XML data such as invoices from a service provider. These invoices have many items with the same structure, for example, Address, Type of service and amount of costs. I need to store this data in separate data sets in different rows. I received an XML schema file from my provider.

I could unmarshall xml files for java objects. Is there any way to insert this data into a database with JPA. the problem is that the generated JAXB classes that do not have annotations, such as Entity or columns, do not. I could annotate these classes, but after “clean and build” with Netbeans, the classes will be generated again without annotations.

Does anyone know a way to create classes from an XML schema with JAXB, read incoming XML files, unmarshal this? and write data to the database.

You can use the Java Bean for the Java Bean, such as Dozer , to map the created classes to JPA objects.
