> Entity name is ignored when specified in the orm.xml file

> Key: OPENJPA-142
> URL: https://issues.apache.org/jira/browse/OPENJPA-142
> Project: OpenJPA
> Issue Type: Bug

>
> The XMLPersistenceMetaDataParser ignores the "name" attriburte of an "entity"
> element, and instead always uses the default alias. For example, with the
> following declaration in the orm.xml file:
> <entity name="Foo" class="mypackage.Bar">
> the entity will be aliased to "Bar", rather than to "Foo".
> Original report by Dain Sundstrom on the open-jpa-dev mailing list:
> 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):
> ERROR - The bean instances business method encountered a system exception:
> Could not locate metadata for the class using alias "BasicCmp2Bean".
