UnsupportedOperationException: Not supported by BasicDataSource

[Marcel Ruff]

Unfortunately it uses openJPA 1.0.1 (my openJPA beans were developed 
with 1.1 - is it compatible?)

But i can't get it to run as i get this exception:

"There were errors initializing your configuration: 
<openjpa-1.0.1-r420667:592145 fatal store error> 
org.apache.openjpa.util.StoreException:
Not supported by BasicDataSource"

The stack trace has no other information but ends too early.
The identical code works fine when is run outside the JTA container 
(transaction-type="RESOURCE_LOCAL")
but fails if set to "JTA". This is a strange behaviour.

Here is part of the persistence.xml:

<properties>
           <property name="openjpa.ConnectionURL" 
value="jdbc:postgresql://localhost:5432/fwgwdb" />
           <property name="openjpa.ConnectionDriverName" 
value="org.postgresql.Driver" />
           <property name="openjpa.ConnectionUserName" value="YYYY" />
           <property name="openjpa.ConnectionPassword" value="XXX" />
           <property name="openjpa.TransactionMode" value="managed" />
           <property name="openjpa.ManagedRuntime"
               
value="jndi(TransactionManagerName=java:/TransactionManager)" />
           <property name="openjpa.Log" 
value="DefaultLevel=TRACE,SQL=TRACE" />
           <property name="openjpa.RetryClassRegistration" value="true" />
           <property name="openjpa.jdbc.DBDictionary" 
value="org.apache.openjpa.jdbc.sql.PostgresDictionary(SupportsDeferredConstraints=false)"/>
            <!--  "postgres" -->
       </properties>

What can i do?

Thanks
Marcel
