  i can also pass along a maven2 project 
Can you post the Java source of the test case and domain classes for us
to reproduce the error? 

afaik, Application identity classes like PageId are not enhanced in
current versions, they used to be.

thanks pinaki,

as a test, i removed Page.book as an @Id, and made the corresponding
change in PageId (removed the book field of type PageId). this caused
the class cast exception below to go away. so, it does appear to have
some relation of to the use of the composite ID within a composite ID,
although you're right it might be a completely different issue.

this is with a trunk (as of this morning) build of openjpa.

i have attached the log you asked for. nothing stood out. i can also
pass along a maven2 project that contains the test case that fails if
that helps. i can't see to attach it here directly though as apache's
spam filter doesn't like it. let me know.

thanks again.

i sent a .zip of the maven2 project to you directly. if there is a better place 
to post it, let me know.

i did not see any difference between the decompiled Page and PageId classes

Hi Jeff,

The pattern you use for Book/Library is

public class BookId implements Serializable {
private String name;
private String library;


The pattern you use for Page/Book is

public class PageId implements Serializable {
private int number;
private BookId book;


Have you tried


public class PageId implements Serializable {
private int number;

it occurs to me that another way to achieve this would be to add

hi craig, thanks ...

your suggestion would imply that that BookId can be converted to and from a 
String object, right? i checked the spec, and i expected to find a requirement 
to have a toString() method and a string constructor that can work in unison to 
this end, but it's not there. maybe i am still thinking JDO.

anyway, i did try that, 

public class PageId implements Serializable {
private int number;

okay, by chance i looked at the open jpa pom and saw that it calls out surefire

however, i still get the exception w/ regard to ObjectId after making the

RE: composite ID w/ another composite ID as a field

2007-04-02 Thread jeff 
after doing some decompilation, the problem line is ...

PageId pageid = (PageId)((ObjectId)obj).getId();

in the enhanced Page class. so, looking at PageId, it's not an instance of 
ObjectId. so, i am not sure what is supposed to be happening here. i assume 
that PageId is supposed to be enhanced in some way. decompiling it shows that 
is not the case.

???

thanks.

Jeff,
   1. The errors look rather unrelated to original problem of composite
id.
   2. The errors apparently caused by enviroment setup, so please
  a) get a clean 0.9.7 openjpa (either building locally from the
source, or pre-built jars from the openjpa web-site)
  b) if the error persists, report with trace-level logging
(property name=openjpa.Log value=DefaultLevel=TRACE/ 
   and complete stack trace.
