I want to get all events in which user participate.
My HQL for it is: from Event e join e.participantsList u where u.userid=:fuserid
but it does not work...help please,pretty please with sugar on top :)

@Entity
public class Event
{
private long eventID;
private Collection<UserData> participantsList;

@Id
@GeneratedValue()
public long getEventID(){return eventID;}
public void setEventID(long eventID){this.eventID = eventID;}

@ManyToMany(cascade = CascadeType.ALL,fetch=FetchType.EAGER)
@JoinTable(name = "event_userdata",joinColumns={@JoinColumn(name = "eventID")},inverseJoinColumns={@JoinColumn(name = "userID")})
public Collection<UserData> getParticipantsList(){return participantsList;}
public void setParticipantsList(Collection<UserData> participantsList){this.participantsList = participantsList;}
}

@Entity
@Table(name="USERDATA")
public class UserData
{
private long userID;
private String nickname;

@Id
@Column(name="USERID")
@GeneratedValue
public long getUserID(){return userID;}
public void setUserID(long userID){this.userID = userID;}

@Column(name="NICKNAME")
public String getNickname(){return nickname;}
public void setNickname(String nickname){this.nickname = nickname;}
}

Tables in db:
event(eventid)
userdata(userid,nickname)
event_userdata(eventid,userid)

solution
HQL : select e from Event as e,UserData as u where u.userID=:fuserid
