I am a new user of hibernate. I tried the airline examples in the middlegen-hibernate-r4. Everything works fine until I did hbm2ddl part. It throws the exception that it can't fine:
net.sf.hibernate.util.ReflectHelper.getBulkBean

Anybody has any idea?

thanx.

Ping

Please give more logs and details.

Hi,

Sorry for late reply.

I was using the examples in hibernate-middlegen-r4 that have 3 tables: person, airline, reservation. I have generated the hbm files and class files. I used the following bat file to generte the ddl file.
@echo off

set JDBC_DRIVER=C:\middlegen\middlegen-hibernate-r4\lib\mysql-connector-java-3.0.11-stable-bin.jar

You obviously don't hav CGLIB library (cglib-full-2.0.1.jar or something like that) in your lib directory.. It comes with Hibernate 2.1 zip, add it to your classpath.
