2:04 p.m.
I have been working on this oc4j issue from the reference guide.
- followed the example from the reference guide chapter for a seam-gen app.
- if <transaction:ejb-transaction> is in the components.xml app gets the exceptions
below. If it is not there everything works fine.
- I broke it down into a smaller problem and did not do the drools, or the reverse eng. on
a db but still had this issue.
- Similar issue on the forum - but in that the JNDI lookup failed and it was JBoss AS
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071599
The weird part is that the JNDI reference to the EjbSynchronizations is found it is just
not the correct object. Instead of an instance of the EjbSynchronizations class it is
instance of com.evermind.server.ejb.StatefulSessionDefaultLocalHomeImpl. Which does not
have the methods from the LocalEjbSynchronizations interface.
I've been comparing the jee5 example because that does not have this issue. One thing
that is different between the jee5 and seam gen is the managed-persistence-context and
entity-manager-factory as described in the guide.
I have been looking over the seam config files over and over, and it was time to get a
second opinion. I have been searching the oc4j docs, and config. Also the jboss-seam.jar
is listed as an ejb-module in app....xml.
ejb from web.xml

Components.xml partial
| <core:init debug="true"
jndi-pattern="java:comp/env/oc4j_gen_drools/#{ejbName}/local"/>
|
| <core:manager concurrent-request-timeout="500"
| conversation-timeout="120000"
| conversation-id-parameter="cid"/>
|
| <transaction:ejb-transaction />
|
| <persistence:entity-manager-factory auto-create="true"
| name="oc4j_gen_droolsEntityManagerFactory"
| persistence-unit-name="oc4j_gen_drools" />
|
| <persistence:managed-persistence-context name="entityManager"
| auto-create="true"
|
entity-manager-factory="#{oc4j_gen_droolsEntityManagerFactory}"/>
|
This could be an issue with oc4j, but I'm not sure. The next thing I was going to try
was a hack to cast the StatefulSessionDefaultLocalHomeImpl to what we expect
EjbSynchronizations (obviouslly just temp).
Thanks,
Jay
