You need to add both models to the hibernate.cfg.xml file.

Hi, 

I have 2 model classes (Employee and Task) which have 
many to many relationship.

I am using appfuse 2.0 with struts 2.0 and maven

When I run the command 

mvn clean compile hibernate3:hbm2ddl

I am getting an error 

Use of @OneToMany or @ManyToMany targeting an unmapped class: 
cam.model.Employee.asignedTaskList[cam.model.Task]


Thanks in advance.
