thanks Alexander,
If I have to find only by the userID primarykey
or only by the listID primary key?.......................
what if I have 3 contructors in the UserListPK
like this...
public UserListPK(String userID)
{
this.userID = userID;
}
public UserListPK(String listID)
{
this.listID = listID;
}
public UserListPK(String userID,String listID)
{
this.userID = userID;
this.listID = listID;
}
.....
will it work????
and what shall I specify in the deployment descripter..
shall I specify both as primary...
tia
indi..
