BUG? HBM2JAVATASK Unable to implement Joined-SubClass separate configuration file (2.1.2)

Can be "

Use the Hibernate extension tool HBM2JAVAtask to generate a profile of the three files according to the profile.

Listening only .HBM.xml file content here.

4.1 payment.hbm.xml

4.2 CreditcardPayment.hbm.xml

"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

4.3 CashPayment.hbm.xml

5. Enter the project catalog in the command line, run Ant, an error, the key prompt is as follows:

Net.sf.hibernate.mappingexception: Cannot Extend Unmapped Class Payment.Payment

6. I don't say anything wrong, I'm boring, just talk about the problem.

6.1 HBM2JAVAtask is looped to the list of profiles, and each file is handled separately, so there is associated class.

6.2 But the CodeGenerator class is not properly, and there is no consideration of file arrangement, because subclasses may be processed before the parent class.

7. The following posts two modified file code. In the modified place, a Chinese comment is added.

* The Initial Ant Task Had Some Initial Filtering on The HBM.XML / Java Names To Only Process The NEeded Files.
