Dain-
I've reproduced this problem and reported it at:
https://issues.apache.org/jira/browse/OPENJPA-142
The only workaround is to add the @Entity(name="someAlias")
annotation to the class in addition to specifying it in the orm.xml
file.

I'm using 0.9.6 and it appears the OpenJPA is ignoring the entity
name when processing queries. In stead it seems to always choose
the class name for the schema name of the bean. For example, I
have the following bean declared in my entity mappings:
<entity name="BasicCmp2Bean"
class="org.apache.openejb.test.entity.cmp.BasicCmp2Bean_BasicCmp2Bean"
>
<description>BasicCmp2Bean</description>
<attributes>
<id name="id"/>
<basic name="firstName"/>
<basic name="lastName"/>
</attributes>
</entity>
The following query does not work:
SELECT o FROM BasicCmp2Bean o WHERE o.lastName = ?1
But this one does:
SELECT o FROM BasicCmp2Bean_BasicCmp2Bean o WHERE
o.lastName = ?1
When the query fails, I get this message (reformatted a bit with **
added to important entries):

I kind of remember Patrick fixing a bug like this but I couldn't
find the email.
