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.

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);

Re: OpenJPA & Transaction configuration
Posted by Abe White <aw...@bea.com>.
If you set the version field of an instance to a non-default value,
OpenJPA assumes the instance was detached, or that you're actively
trying to make it behave as a detached instance.

Thanks for all the feedback, let me remove the @Version (it should really be
a basic field instead as it's app specific) and test it again.

RE: OpenJPA & Transaction configuration
Posted by Patrick Linskey <pl...@bea.com>.
> Here is a link to the source (and no version field):
There is a version field in there. How are you invoking the non-default
constructor? As Abe mentioned, if your version field is set to a value
other than the Java default (0 in this case), OpenJPA will assume that
the instance is detached.

Re: OpenJPA & Transaction configuration
Posted by Matthieu Riou <ma...@gmail.com>.
Here is a link to the source (and no version field):
http://svn.apache.org/repos/asf/incubator/ode/trunk/dao-jpa/src/main/java/org/apache/ode/dao/jpa/ProcessDAOImpl.java
How can I try to change the default detach manager? Which one should I use
instead?
Thanks!

RE: OpenJPA & Transaction configuration
Posted by Patrick Linskey <pl...@bea.com>.
Can you post the source for ProcessDAOImpl? Also, are there any other
OpenJPA properties in your configuration? Finally, I'm assuming that
you're using a somewhat-current 0.9.7-SNAPSHOT. Correct me if I'm wrong.

I believe that you should. I think I remember reading something about
this recently, but I don't remember the details. My suspicion is that
you don't have an @Version field, and you're using the default detach
manager. IIRC, this combination leaves OpenJPA with no way to detect a
detached object vs. a new object, and we default to detached. I thought
that we had improved the docs around this at the least; certainly, it'd
be good to figure out your particulars and make sure that this is
clearer for others.
(IIRC, the default detach manager uses a heuristic on the value in the
version field to determine whether an instance is new or detached.
OpenJPA supports more flexible detach managers that can do fun things
like providing useful errors when attempting to navigate past the end of
a detached object graph, and fine-grained tracking of changes made while
detached. But it's not serialization-compatible with the unenhanced
code, meaning that you need to put the enhanced classes into your client
tier, which I think that we decided was a bad default.)

Re: OpenJPA & Transaction configuration
Posted by Matthieu Riou <ma...@gmail.com>.
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?

RE: OpenJPA & Transaction configuration
Posted by Pinaki Poddar <pp...@bea.com>.
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.
