Hello,
My application uses Tomcat6,derby,spring and OpenJPA 1.20.
My case is stopping derby database and restarting it. And I found even
if I catch the database connection broken exception and create an new
EntityManager successfully after derby restarts, the following
exception stack will be
Hi Daryl,
This is one feature, for a long time, I am interested to be included in JPA
or at least in OpenJPA. Having your queries *only* in the major compilation
unit is a poor idea for usability point of view and takes away much of the
power from tuning a query a posteriori.
However, I had

Naturally, since you're a JPA expert and I'm just a lowly beginner... I was
just putting out a sketch to help folks understand what I was after.
Hi Luis,
Sorry, the re-written query string : and (r = :a or r = :u) that I
suggested is incorrect in syntax.
The bottom line is that r that ranges over an element collection is not a
valid state_field_path_expression that appears as an operand in comparison
expressions.

Alternatively you could just include a MappedSuperclass that holds the query
annotations in your persistence context. No need for a property, but you
have to make sure the MappedSuperclass is part of the PersistenceUnit (add

This is the case for me. In my pre-JPA world I have a
Hi All
I too would much rather see @NamedQuery(ies) defined in a seperate
class like I do other more complicated queries. I also see this as a
good way of keeping things modular or decoupled from the model.
Using a seperate java class which then registers those queries at run
time would be a

Hi Daryl,
Actually, there is an way you can externalize your queries from your Java
code.
orm.xml has a 'global' named-query clause.
1. put you JPQL query string there.
2. If you do not want to write your POJO entities in orm.xml, that is OK.
3. specify orm.xml in mapping-file clause
Hi ,
I want to understand why isDetached is using find. I thought it would be as
simple as reading a boolean variable which is set if detach is caaled on
that particular entity. Furthermore i am not getting the comment below:
// not a part of Query result load. Look into the slices
