Hi,
a Seam portlet accessing two XA resources (database and JMS) via SLSB with CMT throws a HeuristicMixedException on commit. Our "components.xml" contains "<transaction:ejb-transaction/>". In a pure Seam web application we did not get a HeuristicMixedException in that case. Thus, I think the GateIn or the JBoss portletbridge causes the exception.
We use GateIn 3.1.0, Seam 2.2.1.CR2 and JBoss portletbridge 2.1.0.CR1.
Kind regards,
Joerg
