There was already a previous thread on this although I can't seem to find
it off hand. I think some one was looking into it already so there might
be a jira openned.

I should briefly mention that I had the same problem using the MySql
database.
I'm sure I'm not using the SEQUENCE table because I manually created my
database tables and I was just migrating to using the schema generator.
In my case it was tracked down to using an @EmbeddedId in the model clas

So I have a more clear picture of this error now. Quite simply eager
fetching of a persistent collection of strings fails.
as an example :
@PersistentCollection(fetch=FetchType.EAGER)
private HashSet testStrings=new HashSet();
Just create the entity, add a string to the collecti
not as a reference to other entities, is that correct?

I think I've found a bug in @PersistentCollection(fetch=FetchType.EAGER)
when used with Strings. It just doesn't seem to retrieve.
This only happens with FetchType.EAGER and it only happens if the entity
is being loaded from the database / not cached via openjpa.DataCache. (If

Anyone know how to store a collection of enums as Strings instead of their
ordinal values? (preferably with annotations...)
i.e.
@ManyToMany
private Set myEnums=new HashSet();

Hi I'm trying to persista a Collection of Enums in string format and I
can't seem to find much information on how to do this.
There were some things that said it defaults to String but when I
generated the tables (using the MappingToolTask) it comes out as a number
column.
i.e.
public
Incidentally, with the MappingToolTask, if you use schemaAction="dropDB",
at least in MySql, you don't get a drop DB command, you get drop table
commands, which sounds like what you're trying to do. I don't know if this
applies to the schemaTool or what the difference between the MappingTool
an
Does anyone know of a good way to use the mapping tool with a spring
configuration for schema generation?
My main configuration is all done through spring, i.e. my persistence.xml
looks like
http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
that's not entirely true, a lot of resources are loaded at the last
minute, not necessarily when you think you initialised the call.
what I normally do if I'm trying to do a micro-benchmark like this is to
send the operation into something like a 110 time loop and only count
the times of the la

Hi while back we had a discussion on updates (or more specifically
preupdates) always being called even when no changes where made.
I noticed there was an issue OPENJPA-506 openned for this and currently
closed - but this still occurs.
Both anotated @PreUpdate methods as well as updates are alw

why not post your persistence.xml or what ever you're using to configure

I reported this as a bug earlier and I never heard back, it still occurs.
A more detiled explanation of what I found is as follows :
- If you have a new entity with null fields, the fields will save as null.
- If you have an entity which is attached, you can nullify fields as long
as it persis
have a look at the manual secion 8.1.2
generally speaking everything works as you'd expect it. I've been using it
quite a bit with out any problems.

Hi it looks like I've found a bug where if you have an entity with a
Calendar field, and you set the value to null (from a non-null value) and
you use entityManager.merge() to store the state back to the database,
nothing happens.
Not this only happens if you call merge(), if you set it to null

you could try a newer version of openJpa, I used the 1.0 and currently the

So I read the previous explanation which says
"Native queries can only be SELECT statements per the spec; OpenJPA
