Dynamic Persistence Design: Native XML Configuration

The dynamic persistence support includes the use of XML to define the mappings and in effect the dynamic entity class structure. This support includes:

1. Project deployment XML with Native ORM API
2. Sessions.xml with Project deployment XML with Native ORM API
3. Sessions.xml with Project deployment XML with EclipseLink JPA (using PU properties)

= Project XML Usage

The EntityTypeBuilder provides a static helper that allows a resource string describing the location of the project's deployment XMl file and a DatabaseLogin specifying the database connection/pool information.

DatabaseLogin login = AllTests.getTestLogin();
Project project = EntityTypeBuilder.loadDynamicProject("org/eclipse/persistence/testing/tests/dynamic/orm/projectxml/Employee_utf8.xml", login);
 
DatabaseSession session = project.createDatabaseSession();
session.setLogLevel(SessionLog.FINE);
session.login();
