Re: ClassNotFoundException: org.apache.openjpa.util.CacheMap?

Jeffrey-
Actually, it turns out that OpenJPA does extend the JPA spec to support @OneToOne and @ManyToOne field as @Id fields (according to http://openjpa.apache.org/docs/latest/manual/ manual.html#ref_guide_pc_oid_entitypk ). So it sounds like what you are trying to do should work. 


What does your com.sun.portal.pom.PreferenceId look like? Do you have  
primitive fields corresponding to the primary keys of the Preferences  
class, as well as one for the String name field?

thanks marc,


this seems like a very common use case. for example, Book and Page  
entities. A Book has many Pages. obviously a Page object needs to  
somehow factor it's Book into it's ID, otherwise page 1 in Book A  
and page 1 in Book B can't both exist.



i think i worked around, considering the example above, by adding  
an additional String bookName field in Page and making that the ID.  
that field doesn't have a setter of it's own and gets set when the  
book field is set. this results in a less than normalized table,  
but oh well.


thanks for your help.

Jeffrey-


The problem is that a @ManyToOne cannot be an @Id (as per section  
2.1.4 of the JPA spec). You could do it with an @EmbeddedId, but  
only if you actually embed all of the fields of the embedded class  
as primary keys of the (which doesn't appear to be what you want).



I'm a little surprised that OpenJPA didn't give your an earlier  
warning or error about this.

Your attachment got stripped out by the mailing list gateway.

Can you paste in the code for Preference.java?

hi marc,


because there's no pointer to any particular class in the array

also, i tried this w/ 0.9.6-incubating, and i get a different

Hmm ... that's an odd one. Do you have more than one field  
marked as the primary key (@Id)? If so, do you have an  
identity class defined for the entity?



Maybe if you can just paste the code for the entity into an e- 
mail, something might jump out at us.

hi marc,


yes setting the query compilation flag to false made that

looks even scarier.



any ideas? i can make my project available if anyone wants to

That does look like a bug (although not one I've ever seen  
when having a dependency on openjpa).



If you set the property "openjpa.QueryCompilationCache" to  
"false", do you still see the error?
