You must! Strange behavior.
01: ProcessDAOImpl ret = new ProcessDAOImpl(pid,type,guid,this,version);
02: System.out.println("detached " +
((PersistenceCapable)ret).pcIsDetached());
03: _em.persist(ret);
the constructor of ProcessDAOImpl (or some instruction before that)
seems to be doing something that prompts OpenJPA to issue the following
SQL:
(are these three lines just following each other?)
SELECT t0.ID, t0.VERSION, t0.GUID, t0.NUMBER_OF_INSTANCES,
t0.PROCESS_ID, t0.PROCESS_TYPE FROM ODE_PROCESS t0 WHERE (t0.PROCESS_ID
= ?) [params=(String) { http://ode/bpel/unit-test}HelloWorld2-1]
Can you share ProcessDAOImpl and BPELDAOConnectionImpl source + your
persistence.xml?

Thanks! But shouldn't I worry about the fact that a brand new instance
is detached? I could be wrong but it looks like it's more a symptom of
something wrong in my configuration, no?

instead of _em.persist(ret);
try
_em.merge(ret);
as ret is detached instance rather than new.

Subject: OpenJPA & Transaction configuration
Hi,
I'm going back at the OpenJPA implementation for the Apache ODE
project
and am still having problems with the setup. Whan I try to
persist a new
object I get an exception "Attempt to persist detached object".
I guess
the when I instantiate my object OpenJPA can't locate its
transactional
context or something related therefore assuming that the object
is
instantiated outside of any persistent context.
Here is the code that creates the EntityManagerFactory:
HashMap<String, Object> propMap = new
HashMap<String,Object>();
propMap.put("openjpa.Log", "DefaultLevel=TRACE");
propMap.put("openjpa.jdbc.DBDictionary ", "
org.apache.openjpa.jdbc.sql.DerbyDictionary");
propMap.put("openjpa.ManagedRuntime", new
TxMgrProvider());
propMap.put("openjpa.ConnectionFactory", _ds);
propMap.put("openjpa.ConnectionFactoryMode", "managed");
propMap.put("openjpa.Log", "DefaultLevel=TRACE");
_emf = Persistence.createEntityManagerFactory
("ode-dao",
propMap);
And here is my object instantiation code:
ProcessDAOImpl ret = new
ProcessDAOImpl(pid,type,guid,this,version);
System.out.println("detached " +
((PersistenceCapable)ret).pcIsDetached());
_em.persist(ret);
My little debugging statement outputs "true". I've reproduced
the full
log below. I've also encapsulated to transaction manager and the
transaction to check whether OpenJPA was getting the transaction
and
registering a synchronizer properly. It seems to be doing so
(the log
statements are just a couple lines above the '.....'). I've
removed all
the mapping logs just to avoid making this too lengthy.
Any idea of what the problem could be? I'm kind of stuck on this
as it's
hard to debug the enhanced code that gets called when I
instantiate my
process object.
