Hi,
This is in the changes I recently did to the
transaction manager.
When the TM service is started, it adds a
reference to a TPC importer in JNDI under the
name
java:/TransactionPropagationContextImporter
The TPC Importer is used for translating the
serializable transaction propagation context
used on the wire to a Transaction instance
used internally in the VM.
First time a MethodInvocation needs it, it
does a JNDI lookup of this name, and saves
the reference in a class variable for
later use. Whenever the TM service is up,
this should be in JNDI. And TM service
*must* be up, otherwise a transaction
could not have been started, and a
TPC Factory would not have been found in
JNDI (TPC Factory produces the transaction
propagation context (TPC) that the TPC
Importer should import).
I committed these changes about 6 days ago,
and shortly after Hugo Pinto reported a
huge performance decrease (78ms/call) in
the non-optimized embedded Tomcat tests.
About two days ago I committed a fix that
should make performance for non-optimized
VM-local calls with transactional context
a little better, but I have not yet heard
if it helps performance on the non-optimized
embedded Tomcat tests.
I wonder if this last performance fix
completely broke this test. But how? This
last fix only involved moving a class from
jboss-jar to jboss-client.jar, and didn't
change MI or anything in JNDI.
This is very strange. Unless Rickard or
someone else jumps in and says that there
is something special about "java:" JNDI
lookups when running code coming from an
embedded Tomcat, I guess I have to learn
what this Tomcat thing is ;-), and how to
set it up.
Best Regards,
Ole Husgaard.
