Dear all,
I encountered some problems with Transaction
Management porting my J2EE application from Ora9ias
9.0.2 to Ora9ias 9.0.3 platform.
I tried to reproduce the problem with a simple J2EE
application made up of a test stateless session bean
with a single business method.
This very simple J2EE application is deployed
successfully both in Ora9ias 9.0.2 and Ora9ias 9.0.3.
The business method (test_odmg()) can be successfully
invoked by a RMI client on the Ora9ias 9.0.2
deployment.
On the Ora9ias 9.0.3 deployment however I get the
following error:
The following exception has been catched: Error in
ejbCreate(): No external transaction found; nested
exception is:
org.odmg.TransactionNotInProgressException: No
external transaction found

The error arises in the ejbCreate() as soon as the
db.open() is invoked.
- If I move the OJB initialization into the business
method (leaving the EJB as "stateless") the error
disappears.
- If I change the deployment descriptor from
"stateless" to "stateful" (leaving the OJB
initialization into the ejbCreate()) the error
disappears.
What is the rationale behind this behaviour?
Here below you will find
- the source code of the test session bean
- the deployment descriptor
- the OJB.properties
Any assitance in the matter would be great.
Thanks in advance.
Regards,
Dino.

#
# Use the OJB performance tests to decide, which
implementation is best for you.
# The proper way of obtaining a connection is
configured in
# JDBCConnectionDescriptor entries in the

# The LockMapClass entry tells OJB which concrete

# If OJB is running on multiple concurrent clients it
is recommended
# to use the RemoteLockMapImpl. It guarantees to
provide
# Lockmanagement across multiple JVMs.
# This Implemenation relies on a Servlet based
Lockserver. To use it you have to
# deploy the ojb-lockserver.war into a Servlet engine.
# and you have to set the Property LockServletUrl to
point to this servlet.
# (see LockServletUrl section below).
# If OJB is running in a single JVM (e.g. in a desktop
app, or in a servlet
# engine) it is save to use the InMemoryLockMapImpl.
Using it will result
# in a large performance gain.
#LockMapClass=org.apache.ojb.odmg.locking.RemoteLockMapImpl
LockMapClass=org.apache.ojb.odmg.locking.InMemoryLockMapImpl
#
# The LockTimeout entry defines the maximum time in
milliseconds
# that a lock may be hold. Defaults to 60000 = 1
minute
LockTimeout=60000
#
# The ImplicitLocking entry defines if implicit lock
acquisition is
# to be used. If set to true OJB implicitely locks
objects to ODMG
# transactions after performing OQL queries.
# If implicit locking is used locking objects is
recursive, that is
# associated objects are also locked.
# If ImplicitLocking is set to false, no locks are
obtained in OQL
# queries and there is also no recursive locking.
ImplicitLocking=true
#ImplicitLocking=false
#
#
# The LockServletUrl entry points to the Lockserver
servlet.
# This Servlet is addressed by all distributed JVMs if
the RemoteLockMapImpl
# is used.
LockServletUrl=http://127.0.0.1:8080/ojb-lockserver
#
#
# The LockAssociations entry defines the behaviour for
the OJB
# implicit locking feature. If set to WRITE (default)
acquiring a write-
# lock on a given object x implies write locks on all
objects associated
# to x. If set to READ implicit read-locks are
acquired.
# Acquiring a read-lock on x thus allways results in

#----------------------------------------------------------------------------------------
# OQL / SQL settings
#----------------------------------------------------------------------------------------
# The OqlCollectionClass entry defines the collection

# This will be good for most situations as DList
allows maximum flexibility
# in a ODMG environment. See also section 'ODMG
settings'.
# Using DLists for large resultsets may be bad for
application performance.

# and don't have to be declared public or protected
# - PersistentFieldPrivilegedImpl
# Same as above, but does cooperate with
AccessController and do not
# suppress the java language access check.
# - PersistentFieldIntrospectorImpl
# uses JavaBeans compliant calls only to access
persistent attributes.
# No Reflection is needed. But for each attribute
xxx there must be
# public getXxx() and setXxx() methods.
# - PersistentFieldDynaBeanAccessImpl
# implementation used to access a property from a
# org.apache.commons.beanutils.DynaBean.

# for each field determines upon first access how to
