Question

I need to create a connection with a table that isn’t in my control yet there’s a one-to-many relationship so I’m having a bit of trouble with the hibernate mappings.

table1:

userId
firstname
lastname

table2:

user_id <= fk to table1.userId 
x_id
create_date

table3:

x_id
private1
private2

So my problem is that despite it being a one-to-many in reality I’ll probably have to map it as a many-to-many. And a problem is that one of the column names in table 2 doesn’t match the column name it references to in table 1. An additional problem I have is that in table 2 user_id and x_id form a combined primary key.

So far I’ve been using Hibernate mapping files and not annotations.
And I’d like to use an arraylist.

If i understand you correctly, you should map it as many to many relation using composite primary key.
