Question

I am having problems generating a app(using “seam generate” after “seam create-project”)
With identifying relationship like Role , User and User_has_Role.
It generates the 3 one-to-many , many-to-one entities instead of 2 @manytoMany entities.
I have seen a similar question here seam-gen doesn't generate EntityQuery interfaces for @ManyToMany members

In this post here, he managed to generate many to many entities http://community.jboss.org/thread/146500

Can seamgen generate many-to-many entities ?

If i use hibernate tools separately it generates the entities correctly.
I used seamgen 2.2.1CR2

Ok, so this is not possible to do with seam-gen as the question you are linking too.

This is how to do it manually (which is very easy).

In your User.java entity, write the following.

@UserRoles
@ManyToMany
@JoinTable(name = "UserRoles", joinColumns = @JoinColumn(name = "userId"), inverseJoinColumns = @JoinColumn(name = "roleId"))
public List<Role> getRoles() {
    return roles;
}

This should be enough to generate/map the UserRoles table for you
