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.
My code:
