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

Thu, 02 Aug 2007 08:18:24 -0700 

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 
index out of bound trace, i attached the project consisting of 12 
classes. you if you start derby on localhost, you can do a mvn test 
and see the problem.



also, i tried this w/ 0.9.6-incubating, and i get a different 
problem ... the other two problems go away.

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 error 
go away. however, now i get the trace below, which looks even 
scarier.



any ideas? i can make my project available if anyone wants to try 
it locally.

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?
