Question on JPQL...

I need help in formulating a JPQL query in this situation:
1. I have Customer and Order entities and I want all the Customers who have ordered something. I am thinking:
select c from Customer c, In(c.orders) o
Is that correct? Would the query be different in EJBQL and JPQL for this situation?
2. What if I want all the customers who have an order that is larger than say 100$?
select c from Customer c, In(c.orders) o where o.amt>100
Also, can someone point me to some resource that contains differences between EJBQL and JPQL?? I am really confused with both.

How about we move this to the more appropriate ORM forum, which covers JPA questions. Instead of it being linked from another thread you created in the ORM forum.
