Re: Timestamp in JPQL where clause issue
Hi, Can you please change the parameter name from to something else? The error is during parse and may have be related to the fact that from is a reserved word in JPQL. - Pinaki -- View this message in context: http://n2.nabble.com/Timestamp-in-JPQL-where-clause-issue-tp3332190p550.html Sent from the OpenJPA Users mailing list archive at Nabble.com.

One-sided @OneToMany
Hi, I'm new to OpenJPA. Just few background words before my first question. My walk to OpenJPA was Hibernate when it was early alpha on persistence with annotations, then CakePHP for the shake of simplicity and now OpenJPA because : * fetch group. I didn't know the name before I read OpenJPA's doc, but I need this and did that by hand before ... I found I won't feel lonely anymore when I read that part of the doc :-) * it is standard * it look really clean * I need more power than CakePHP or Hibernate can provide * I'm more than happy to come back to Java (leaving PHP) on that part :-) So, I have a question on one-sided @OneToMany relationship. Chapter 7.7.7 of the doc handle that case, but I would like to avoid using specific things when possible. Why do I have to use @ElementJoinColumn annotation that apparently (looking to imports) is not from JPA but is part of OpenJPA ? Does it mean that this kind of very common @OneToMany relation is not part of JPA ? Did I use the wrong annotation (@ElementJoinColumn), is there a standard JPA way of doing that ? If an example is needed to explain, let's consider a Command that have many CommandLine. One CommandLine can be under one and only one Command. So this example is typically handled by a one-sided one-to-many relation where we'll found a command_id column in the CommandLine table. Any feedback appreciated ! JBB.

JTA and Resouce_Local setup
I have object structure like this in my project. I have a SessionBean around a jpa entity like this. Jpa: Person--Customer---Invoices(Collection)---Data when i run a test on persistence.xml in Resouce_Local it works fine as finding a person returns the entire structure including the collection of invoices. However , the same setup when run in the container does not return all structure it only returns up to Person--Customer. as a result application throws exceptions because of missing data. I am using wasce2.1.1.2 and apache Derby. Jta XA datasource. I am also using container injection of entityManager into sessionBean. Clearly something is wrong with the JTA and why the same persistence.xml will return different results between JTA and Resouce_Local ? Any Ideas? -- View this message in context: http://n2.nabble.com/JTA-and-Resouce_Local--setup-tp3334116p3334116.html Sent from the OpenJPA Users mailing list archive at Nabble.com.

Re: enhancing entity which is a subclass
After looking at the spec, it looks like you should be using the mapped-superclass XML descriptor on the UserModelBaseImpl class and com.example.model.impl.UserModelImpl needs to be added to your list of persistent classes. See section 2.11 - 'Inheritance' for more details.

Very weird enhancement error - is the class enhanced or not? - OpenJPA seems confused
I am getting a very strange error when calling persist/merge on my entity under only one specific case. Basically I have a User entity and a UserProfile Entity. The User entity has a one to one mapping to the UserProfile entity. This is all working fine. I have a Country entity, a Locale entity and Currency entity, all of which I can create,persist,merge with no issues. The problem occurs when I add a many to one relationship to my UserProfile entity for a Country entity. When I persist/merge a User entity, it cascades to its related UserProfile which in turn cascades to its Country entity. So here is the relationship: User -à UserProfile à Country When I call persist/merge on the User entity I get this error: openjpa-1.2.0-r422266:683325 nonfatal user error org.apache.openjpa.persistence.ArgumentException: No metadata was found for type class java.lang.Class. The class is not enhanced. That doesnt make any sense because there is no generic class in the entities being saved. To confuse the issue, when I have an empty UserProfile table, I get the same error but the UserProfile does get saved. Later when I try to make a change to the UserProfile on the User and call merge, then I get the same error but the UserProfile is not updated. To confuse things even more, if I add the other two additional entities to UserProfile (currency and locale) then they work just fine. The other two entities are actually the same class as the Country class just renamed. All these classes are defined in my persistence.xml and I can do anything to them (persist/merge) if I use them by themselves, but only under the scenario described above will I get this issue. Does anyone have a clue what might be the issue? I put on trace logging but cant see any insert/update query being executed due to this metadata issue.

RE: Very weird enhancement error - is the class enhanced or not? - OpenJPA seems confused
Hi Ravi,
Here is what gets executed:
public Object find(Object co, String uid)
{
Class clazz = co.getClass();
Object existing = em.find(clazz, uid);
return existing;
}
EM is an instance of the Entity Manager, but since tis code is used
everywhere in my code, and the fact that the currency and the locale in the
UserProfile use exactly the same code as the Country, it doesn't make sense
that the Country entity is the only one giving the issue.
Chris

OpenJPA seems confused
I am getting a very strange error when calling persist/merge on my entity
under only one specific case.
Basically I have a User entity and a UserProfile Entity. The User entity has
a one to one mapping to the UserProfile entity. This is all working fine.
I have a Country entity, a Locale entity and Currency entity, all of which I
can create,persist,merge with no issues.
The problem occurs when I add a many to one relationship to my UserProfile
entity for a Country entity. When I persist/merge a User entity, it
cascades to it's related UserProfile which in turn cascades to its Country
entity. So here is the relationship:
User -à UserProfile à Country
When I call persist/merge on the User entity I get this error:
openjpa-1.2.0-r422266:683325 nonfatal user error
org.apache.openjpa.persistence.ArgumentException: No metadata was found for
type class java.lang.Class. The class is not enhanced.
That doesn't make any sense because there is no generic class in the
entities being saved.
To confuse the issue, when I have an empty UserProfile table, I get the same
error but the UserProfile does get saved. Later when I try to make a change
to the UserProfile on the User and call merge, then I get the same error but
the UserProfile is not updated.
To confuse things even more, if I add the other two additional entities to
UserProfile (currency and locale) then they work just fine. The other two
entities are actually the same class as the Country class just renamed.
All these classes are defined in my persistence.xml and I can do anything to
them (persist/merge) if I use them by themselves, but only under the
scenario described above will I get this issue.
Does anyone have a clue what might be the issue? I put on trace logging but

RE: Very weird enhancement error - is the class enhanced or not? - OpenJPA seems confused
Hi Chris,
This exception can be seen if co.getClass() returns Class.class.
You can may be print clazz before e.find() to see if it is correct.
Once it is confirmed, then we can try to isolate the reason for why
co.getClass() returns Class only for a country and not for other entities.
Are you getting this exception everytime the following stack trace is traversed
?

Ravi.

Re: inconsistent SQL's RESOURCE_LOCAL Vrs JTA
Hi, My guess is that the SQL generation should not be different between JTA and RESOURCE_LOCAL. Can you please add default trace level logging to both the scenarios and attach the logs here. That way we can compare between both scenarios and find if there are any differences in the properties between JTA and RESOURCE_LOCAL. You may already know, adding property name=openjpa.Log value=DefaultLevel=TRACE/ to persistence.xml will set the logging level to trace. Regards, Ravi. brobbsnet wrote: please my project runs ok and generate all Sql statements under RESOURCE_LOCAL persistence.xml. when i change to run in the container using JTA , it does not generate the same number on sql statements causing the application to throw exceptions. for example when i run a test under RESOURCE_LOCAL, it prints out this two sql statements as follows. 1.

I am using WASCE (websphere community edition Version 2.1.1.2) and Apache Derby database. Is there something in the JTA configuration that i am missing ?
