I've not done this before so maybe I'm missing something basic but I have
followed the docs as far as I can see.
I have an Entity User, which I want to have multiple addresses so I simply
added a I thought were the appropriate annotations and members like so:
private Collection <Address> addresses;
*/
public void setAddresses(Collection <Address> addresses) {
this.addresses = addresses;
}
@OneToMany(cascade={CascadeType.ALL})
@JoinColumn(name="id")
public Collection <Address> getAddresses() {
return addresses;
}
As soon as I add the @OneToMany annotation and OpenJPA starts to generate
the tables, it throws an exception complaining I am using both field and
property access, however the exception lists no members using field access
and only 1 using property access so I a not sure why it is telling me I am
using both.
Here is the stack trace, thanks for any advice!:
