GroupHBM class structure

public class GroupHBM {
protected GroupHBM() {
}
private String _groupId;
private String _companyId;
private String _parentGroupId;
private String _name;
private String _layoutIds;
private String _wikiNodeIds;
private Set _roles;
private Set _users;
}

UserHBM class structure is

public class UserHBM {
protected UserHBM() {
}
private String _userId;
private String _portalId;
private String _password;
private boolean _passwordEncrypted;
private Date _passwordExpirationDate;
private String _firstName;
private String _middleName;
private String _lastName;
_(some of the field i left for convineance not necessary for our problem)
}

when we tried to change primary key (commented part in the mapping file) into composite key( non commented part in the mapping file).

the above exception occur.

whether i don't give proper name for "userId" in the persistors class or in the mapping file(portal-hbm).

userHBM.id.userId
