Project: EJB 3.0
Issue Type: Bug
Components: EJB3 Extensions
Affects Versions: AS 4.2.1.GA
Environment: JBoss Bootstrap Environment
JBOSS_HOME: C:\jboss-4.2.1.GA
JAVA: C:\Program Files\Java\jdk1.5.0_09\bin\java
JAVA_OPTS: -Dprogram.name=run.bat -server -Xms128m -Xmx512m

Two entities relates as many to many (Course and Student).
During deployment it throws:
Caused by: org.hibernate.MappingException: Could not determine type for:
java.util.Collection, for columns: org.hibernate.mapping.Column(students)]
Both sides using Generics.
Here is the latest code:
@Entity(name = "StudentUni")
public class Student implements Serializable {
private int id;
private String name;
private Collection<Course> courses = new ArrayList<Course>();
public Student(){
id = (int) System.nanoTime();
}
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@ManyToMany
public Collection<Course> getCourses() {
return courses;
}
public void setCourses(Collection<Course> courses) {
this.courses = courses;
}
}
@Entity(name = "CourseUni")
public class Course implements Serializable {
private int id;
private String courseName;
private Collection<Student> students = new ArrayList<Student>();
public Course(){
id = (int) System.nanoTime();
}
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCourseName() {
return courseName;
}
public void setCourseName(String courseName) {
this.courseName = courseName;
}
@ManyToMany(mappedBy = "courses")
public Collection<Student> getStudents() {
return students;
}
public void setStudents(Collection<Student> students) {
this.students = students;
}
}
