Hi Emmanuel,
Thanks for your answer. This is how it looks:
First, the Principal - Group m-m ralationship where the principal is a member
of the group
The Group persistence bean
@ManyToMany( cascade = {CascadeType.PERSIST, CascadeType.MERGE},
| fetch = FetchType.EAGER)
| @JoinTable(
| [EMAIL PROTECTED](name="PRINCIPAL_GROUP"),
| [EMAIL PROTECTED](name="GROUP_ID")},
| [EMAIL PROTECTED](name="PRINCIPAL_ID")}
| )
| public Set<Principal> getMembers() {
| return members;
| }
Now the Principal persistence bean
@ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE},
| fetch = FetchType.EAGER,
| mappedBy="members")
| public Set<Group> getGroups() {
| return groups;
| }
Now the Principal - Group m-m relationship where any number of principals own
any number of groups
This is the Principal persistence Bean
@ManyToMany( cascade = {CascadeType.PERSIST, CascadeType.MERGE},
| fetch = FetchType.EAGER)
| @JoinTable(
| [EMAIL PROTECTED](name="PRINCIPAL_OWNED"),
| [EMAIL PROTECTED](name="PRINCIPAL_ID")},
| [EMAIL PROTECTED](name="GROUP_ID")}
| )
| public Set<Group> getSerfs() {
| return serfs;
| }
On the Group side
@ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE},
| fetch = FetchType.EAGER,
| mappedBy="serfs")
| public Set<Principal> getOwners() {
| return owners;
| }
I've also tried to have both relationship table definitions in one persistence
bean.
