David Jencks commented on GERONIMO-5824:
----------------------------------------
Thanks for looking into this.
in the persistence.xml you can specify <jta-datasource> and
<non-jta-datasource>. In this case only the <non-jta-datasource> was
specified. However, the datasource configured there should have had
<no-transaction/> in its plan but had either
<local-transaction/>
or
<xa-transaction/>
Openjpa uses the non-jta-datasource for things like creating tables, getting
"sequence" values from tables outside a jta transaction, and similar things.
It uses the connection.commit style of local transaction management which
causes exceptions if the connection is already enrolled in an XA transaction
since it's from a transactional datasource.
If this is not enough information let me know.
> jpa JTA transaction and missing jta-data-source should be warned about or
> rejected

> Someone just had a lot of weird transaction errors that turned out to be
> because they had configured a persistence.xml with JTA transaction support
> and only a non-jta-datasource that was actually transactional. When both the
> tm and openjpa tried to control the tx confusion enused.
> We can detect this situation on deployment and either reject it or at least
> loudly warn about it.
