Hi Lars,
that is a weird error that I haven't seen before - it looks like OpenJPA is
confusing the table name with the class name.
In case it helps, you don't need to reference the orm.xml in the
persistence.xml. Not sure if it's a problem when you do, try without.
orm.xml looks like it's in the same directory as persistence.xml from your
email. perhaps you should double-check.
my orm.xml header is slightly different:
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
http://java.sun.com/xml/ns/persistence/orm_1_0.xsd";
version="1.0">
I do not run the OpenJPA enhancer and you shouldn't need to, but I am using the
OpenJPA v1.1.0 snapshot, not 1.0.x.

Hi,
Can anyone point me to a working standalone example there a a orm.xml file
is used instead of Annotations?
I'm able to build a small example with annotations but if I try the same
with orm.xml I receive the following error:
Exception in thread "main" <openjpa-1.0.2-r420667:627158 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Could not locate metadata
for the class using alias "MYAPPLICATION.PEOPLETABLE". This could mean that
the OpenJPA enhancer or load-time weaver was not run on the type whose alias
is "MYAPPLICATION.PEOPLETABLE". Registered alias mappings: "{
MYAPPLICATION.PEOPLETABLE=null, Person=[class datamodel.Person]}"
I have the following orm.xml
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/ormorm_1_0.xsd";
version="1.0">
<entity class="datamodel.Person">
<table name="MYAPPLICATION.PEOPLETABLE"/>
<attributes>
<id name="id" />
<basic name="firstName" />
<basic name="lastName" />
<transient name="nonsenseField" />
</attributes>
</entity>
</entity-mappings>
I have the following persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
