Description

« Hide

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". Registered alias mappings: "{
AllowedOperationsCmp2Bean_AOBasicCmp2Bean=

This can be worked around by adding the annotation to the class (e.g., @Entity(name="Foo") ).

I think I found a related bug to this. When you have a mapped-superclass and an entity with the same class name (but not the same package). The query compiler seems to get confused and throws the exception following this message.

You should be able to reproduce this by putting your sub class in a different package but with the same class name, and executing any query. I'm not sure if this problem goes away by annotating the entity as you described above.

I have a similar problem with a really veru simple test that works as expected with TopLink (RI) and Hibernate implementations.
I've tried to add the "name" attribute to the entities annotations, or disable the orm.xml use, but this work-around doesn't seem to work in my case.
I've tested it with the release 0.9.6 and snapshot 0.9.7, and i have the same result...
Does anyone have more ideas ?
NB : I attach my project, just in case...
