             Summary: Use of uni-directional @OneToMany leads to an exception
                 Key: OLINGO-526
                 URL: https://issues.apache.org/jira/browse/OLINGO-526
             Project: Olingo
          Issue Type: Bug
          Components: odata2-jpa
    Affects Versions: V2 2.0.1
            Reporter: Michael Bolz


Issue occurs with use of {{JPA Processor Extension}}.

If a uni-directional {{@OneToMany}} is used the creation of the {{metamodel}} 
fails with following exception:

{code}
java.lang.IllegalArgumentException
No [EntityType] was found for the key class [java.util.List] in the Metamodel - 
please verify that the [Entity] class was referenced in persistence.xml using a 
specific <class>java.util.List</class> property or a global 
<exclude-unlisted-classes>false</exclude-unlisted-classes> element.
{code}

in

{code}
org.eclipse.persistence.internal.jpa.metamodel.MetamodelImpl
entityEmbeddableManagedTypeNotFound
173
org.apache.olingo.odata2.core.ep.AtomEntityProvider
writeServiceDocument
157
{code}


Example code:
{code}
        @OneToMany
        @JoinColumn(name = "requestForQuotationUUID", referencedColumnName = 
"requestForQuotationUUID")
        private List<Quotation> quotation;
{code}
