Hi,
The slices feature is very interesting, we tried it, but honestly did
not get far (in 1.2.0), we would like to ask some questions about it:
*) firsthand I was running into the error that was also reported in the
thread "Problems with configuring OpenJPA..." started by thiago ananias
(Aug 22nd). I applied the patch reported by ahsoni on (Sep 17th) and the
entire thing went further. However, I was not able to find a JIRA entry
for that issue - is there one?
*) then - when actually getting a first new EntityManeger - I got the
problem that I get an UnsupportedOperationException at
DistributedStoreManager.java:283, interesting stacktrace is
at
org.apache.openjpa.slice.jdbc.DistributedStoreManager.getClientConnectio
n(DistributedStoreManager.java:283)
at
org.apache.openjpa.kernel.DelegatingStoreManager.getClientConnection(Del
egatingStoreManager.java:159)
at
org.apache.openjpa.kernel.BrokerImpl.getConnection(BrokerImpl.java:3697)

org.apache.openjpa.kernel.DelegatingBroker.getConnection(DelegatingBroke
r.java:452)
at
org.apache.openjpa.persistence.EntityManagerImpl.getConnection(EntityMan
agerImpl.java:1051)
tracking to the code is pretty straight forward until we got the
surprise that getClientConnection() is actually empty and only the
exception is thrown. I wondered if there would not be any slice handling
coming down this trace? Anyone a hint, what could be the reason when I
end up with DistributedStoreManager.getClientConnection()?
*) setting "openjpa.slice.TransactionPolicy" in section 4.6 of the
chapter 12 (still OpenJPA 1.2.0 docu) returns: "The configuration
property named "openjpa.slice.TransactionPolicy" was not recognized and
will be ignored, although the name closely matches a valid property
called "openjpa.slice.TransactionMode"." is there something wrong with
the property?
We are just interested in the slices-part of OpenJPA, so any information
about these issues would be welcome.
Thanks in advance,
Michael
