Hi objectuser,
Thanks for the links - very helpful. I have had a look and studied
them. I am trying to get your example to work but am getting the
error.
org.springframework.transaction.CannotCreateTransactionException:
Could not open JDO PersistenceManager for transaction; nested
exception is java.lang.IllegalStateException: No JDO
PersistenceManager bound to thread, and configuration does not allow
creation of non-transactional one here
at
org.springframework.orm.jdo.JdoTransactionManager.doBegin(JdoTransactionManager.java:
359)
As far as I can see I have set up everything as should be but am
missing something obvious because it just will not work. It might be
something to do with the aop config but I cannot be sure. I have read
the Spring documentation and your example which are very similar.
Below is my revised spring xml and I have included example dao code as
well. If anyone can see what I am doing wrong please correct me.
Thanks.
