Hello everyone,

I am having problems creating an IdClass. I get the following errors:

I have attached the files for your convenience. As you may notice, I have been

messing around with it trying to get it right. Orderlineent is the entity of the breakdown of many to many

relationship for Order & Items and Customer. So Orderlineent does not have and Id of it's own that's why

I need the IdClass.

Please, help. I can't figure out why this error and can't deploy it.

Thanks

eve
