Hello,
I am using Hibernate2.x for ORM and would like to use XDoclet for generating HBM files.

I have composite key in the tables.
So can somebody guide me about how to generate HBM file using XDoclet for composite IDs?

Also why does composite IDs have to be n different class?

Code samples would be useful..

Thanks in advance

search the forum, especially in the tools. this has been discussed many times

There's nothing special about mapping a composite ID using XDoclet from mapping a primitive ID, just use @hibernate.id tag as you always do:

/**
* @hibernate.id
*/
public YourCompositeId getId() {
return id;
}

XDoclet automatically detects from the return type whether the ID is composite or primitive. As primitive ID data types are considered int, long, float, double, boolean, byte, short, char, java.lang.Byte, java.lang.Double, java.lang.Float, java.lang.Integer, java.lang.Long, java.lang.Short, java.lang.String, java.math.BigDecimal and User Types. Any other data type (including your composite ID class) is considered as composite (ie. including java.util.Date). I use XDoclet CVS build 1.2.2.

HTH,
Pavel
