We've solved this, the problem was that I have missed table element in my orm.xml, at least this is the only reasonable difference I can point between two:
=== not overriding orm.xml === <orm:entity-mappings version="1.0" xmlns:orm=" 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";> <orm:description> An attempt to override annotations for OpenJPA annotations for org.intalio.tempo.workflow.task.Task to avoid column name "tid". </orm:description> <orm:entity class="org.intalio.tempo.workflow.task.Task" > <orm:attributes> <orm:basic name="ID"> <orm:column name="itd"/> </orm:basic> </orm:attributes> </orm:entity> </orm:entity-mappings> ======================================== ==== the right one =============== <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"> <description> An attempt to override annotations for OpenJPA annotations for org.intalio.tempo.workflow.task.Task to avoid column name "tid". </description> <entity class="org.intalio.tempo.workflow.task.Task" > <table name="tempo_task"/> <attributes> <basic name="_id"> <column name="itd"/> </basic> </attributes> </entity> </entity-mappings> ======================================== Thanks! -Oleg On Thu, Apr 2, 2009 at 5:01 PM, Oleg Zenzin <[email protected]> wrote: > Hello > > I need to use both annotations and orm.xml to sometimes override mapping > defined with annotations in the compiled file.
