Hi Scott,
I'm upgrading snap080331 to snap080417. I found my hibernate persistence
unit not
working, with no jta-data-source configured.
I added 080417 src into my project and traced for a while and found the
reason.
I put an breakpoint at com.caucho.naming.Jndi.bindImpl(...) line:91 and
recorded
the jndi resources registered at order below:
"java:comp/env/jmx/MBeanServer" ...
"java:comp/env/jmx/GlobalMBeanServer" ...
"java:comp/UserTransaction" ...
"java:comp/TransactionManager" ...
"java:/TransactionManager" ...
"java:comp/ThreadPool"
"java:comp/env/caucho/persistent-store"
and then my singleton beans were then initialized, then
"java:comp/env/jdbc/stock" // my <database> config in resin-web.xml
"java:comp/env/activemq" // my <connection-factory> config in
resin-web.xml
Some of singleton beans need to access database by inject a EMF, so amber
start to
load persistence unit. During parsing the persistence.xml, the xml config
will set the
"jta-data-source" property of the com.caucho.amber.cfg.PersistenceUnitConfig
object
by reflection. Before doing it, it will call JNDI.lookup to find the
DataSource with name
specified in persistence.xml, of cource nothing found! It was not registered
yet!
I switched to snapshot080331 binary and still retained some src of 080417
(src package:
com.caucho.amber, com.caucho.config, com.caucho.naming) then traced it
again.
This time I recored the the jndi resources registered at order below
"java:comp/env/jmx/MBeanServer" ...
"java:comp/env/jmx/GlobalMBeanServer" ...
"java:comp/UserTransaction" ...
"java:comp/TransactionManager" ...
"java:/TransactionManager" ...
"java:comp/ThreadPool"
"java:comp/env/caucho/persistent-store"
"java:comp/env/jdbc/stock" // my <database> config in resin-web.xml
"java:comp/env/activemq" // my <connection-factory> config in
resin-web.xml
and then my singleton beans were then initialized.
This is the right sequence.
Though I didnot do further test, I think problem were not belonged to the
three packages
I retained during the two snapshot version switch.
Suggestions are appreciated, thanks.
-Wesley
