--------------------------------------
Hi Chandan,
It works fine. Here is the way how I use many to many relations in JPA (as
example of the relation Company entity assignment to User entity is used):
In User entity:
@ManyToMany
private List<Company> companies = new ArrayList<Company>();
In Company entity:
@ManyToMany(mappedBy="companies")
private List<User> users = new ArrayList<User>();
Br, Aleh

> Hello,
> Something strange is happening when I try to specify several relations of
> type manyToMany in one entity (lets say relation A from entity 'a' to entity
> 'b' and B from entity 'a' to entity 'c'). If I keep just relation
> A or just relation B I can see this relation in the metadata with
> Multiplicity * to *.
> When I keep both - both relations are gone from the metadata.
> Here are relations representation in JPA:
> @ManyToMany(targetEntity=Phase.class)
> @JoinTable(name="user_phase",joinColumns = @JoinColumn(name="userName",
> referencedColumnName="userName"), inverseJoinColumns = @JoinColumn(name =
> "phaseGuid", referencedColumnName="guid"))
> private java.util.Collection<Phase> phases;
>
> @ManyToMany(targetEntity=Role.class)
> @JoinTable(name="user_role",joinColumns = @JoinColumn(name="userName",
> referencedColumnName="userName"), inverseJoinColumns = @JoinColumn(name =
> "roleName", referencedColumnName="roleName"))
> private java.util.Collection<Role> roles;
> With best regards, Aleh
