hi, a fix for openjpa-659 has been added. but have tested it only against JSE environment. If possible, you can apply the change in your environment to let us know if that changes anything.

Yeah, me too. The difference might be due to something in your classes being enhanced differently using one enhancement technique versus another.

Re: no state snapshot available on embedded mapping
Hi,
I am not familiar enough with runtime enhancement, so please accept my
explanation with certain degree of disbelief.
OpenJPA tracks the dirty fields of managed instances and traditional
(i.e. build-time) enhancement ensures that at bytecode level on field
mutators. Runtime enhancement is also able to track dirty fields
when
a) Java 6 is the runtime
b) Java 5 and entity using property access and are loaded from database
(not for new instances)
In Java 5, the entities with field access are not tracked and hence
during commit session, OpenJPA resorts to state comparison for such cases.
This checking is skipped on certain cases, as described below:
private boolean needsDirtyCheck() {
if (isIntercepting())
return false;
if (isDeleted())
return false;
if (isNew() !isFlushed())
return false;
+if (!isTransactional())
+return false;
return true;
}
Including non-transactional entities to skip dirty check resolves the
issue you have encountered. Exclusion of nontransactional entities form
dirty checking sounds logical to me but due to my limited understanding of
runtime enhancement I am not able to confirm.
* pFields are tracked for all classes that are run through the
OpenJPA
* enhancer prior to or during deployment, and all classes (enhanced or
* unenhanced) in a Java 6 environment or newer./p
*
* pIn a Java 5 VM or older:
* br- instances of unenhanced classes that use
* property access and obey the property access limitations are tracked
* when the instances are loaded from the database by OpenJPA, and are
* not tracked when the instances are created by application code.
* br- instances of unenhanced classes that use field access are
* never tracked./p
Change tracking of classes

Hi,
yes, i am using a spring-tomcat-weaver.jar in Tomcat6 (with Java5) to
achieve JPA runtime enhancement via Spring.
What do you mean with workaround? Should this work normally ? I was
quite happy with runtime enhancement, would be sad to leave that
path
thx for infos

If yes, the immediate workaround is to enhance the persistent

Re: no state snapshot available on embedded mapping
here we go: https://issues.apache.org/jira/browse/OPENJPA-659 -- Marc Logemann blog http://logemannreloaded.blogspot.com privat http://www.logemann.org Am 14.07.2008 um 18:24 schrieb Craig L Russell: Could you please file a JIRA with the relevant detail? Thanks, Craig
no state snapshot available on embedded mapping
Hi,
i am getting this exception:
org.springframework.orm.jpa.JpaSystemException: No state snapshot is
available for instance of type de.logentis.bwh.model.Payment, but
this instance uses state-comparison for dirty detection.; nested
exception is openjpa-1.1.0-r422266:657916 fatal general error
org.apache.openjpa.persistence.PersistenceException...
Here are the relevant pieces of the casses:
@Entity
@Table(name = orders)
@VersionColumn(name = _version)
public class Order {
...
@Embedded
Payment payment;
}
@Embeddable
public class Payment {
@Basic
@Enumerated(EnumType.STRING)
@Column(name = paymenttype)
PaymentType type;
@Column(name = currency)
String currency;
@Column(name = pricing)
String pricing;
@Column(name = cost)
int cost;
}
The point is, persisting is no problem at all, the exception will be
thrown by issueing:
Query query = getEntityManager().createQuery(select o FROM Order o);
query.getResultList();
What have i made wrong here? Looked in the docs and everything seems
like expected
