Hi,
Are there any plans for hibernate-tools to support EJB3 configurations?
Here is my horrible hack to get the generated schema.
public static void generateDDL(String ddlFileName) throws
SecurityException,
NoSuchFieldException, IllegalArgumentException,
IllegalAccessException {
Ejb3Configuration cfg = new Ejb3Configuration();
HashMap<String, String> overridden = new HashMap<String,
String>();
overridden.put("hibernate.hbm2ddl.auto", "create-drop");
// The following line actually drops and creates the DB schema.
// If only JBoss would refactor the code better.
EntityManagerFactory emf =
cfg.createEntityManagerFactory("edesk-test",
overridden);
// Now go rummaging in emf's underpants (looking for privates
- of
course)
Field sessionFactoryField =
emf.getClass().getDeclaredField("sessionFactory");
sessionFactoryField.setAccessible(true);
SessionFactoryImpl sfi = (SessionFactoryImpl)
sessionFactoryField.get(emf);
Field schemaExportField =
sfi.getClass().getDeclaredField("schemaExport");
schemaExportField.setAccessible(true);
SchemaExport schemaExport = (SchemaExport)
schemaExportField.get(sfi);
// Now we have the SchemaExport, so we can generate the DDL now.
schemaExport.setOutputFile(ddlFileName);
schemaExport.setFormat(true);
schemaExport.setDelimiter(";");
schemaExport.execute(false, false, false, true);
}
As you can see, I use reflection to rummage around in the internals.
There
must be a better way to do this, but it involves refactoring the
EJB3Configuration class.
Ciao,
