Sir ,I find hibernate can't support comsiteid for one class mapping some table . i have some table

Table_1_1_3_2_1 [col_1_1_3_1,it_state,col_1_1_3_13]
Table_1_1_3_2_2[col_1_1_3_1,it_state,col_1_1_3_66]
Table_1_1_3_2_3[col_1_1_3_1,it_state,col_1_1_3_116]

col_1_1_3_1,it_state is primary key !

now i want one class mapping some table

example SQL: select a.col_1_1_3_1,a.it_state ,a.col_1_1_3_13,b.col_1_1_3_66,c.col_1_1_3_116 from Table_1_1_3_2_1 a inner join Table_1_1_3_2_2 b a.col_1_1_3_1=b.col_1_1_3_1 and a.it_state =b.it_state inner join Table_1_1_3_2_3 c a.col_1_1_3_1=c.col_1_1_3_1 and a.it_state =c.it_state

but 3.0 support it !this is a commonly apply for database operation,so do you intend slove this problem?

<join table="Table_1_1_3_2_2">
<key column="col_1_1_3_1"/>
<key column="it_state"/>
<property name="col_1_1_3_66" column="col_1_1_3_66"/>
<property name="col_1_1_3_67" column="col_1_1_3_67"/>
</join>


above <join ../> only support one <key/> why not support some <key/> this is important for somebody!

have you read the docs and DTD ?

<key> can contain multiple columns - isn't that what you want ?
