Hi All, I have a webapp that use the built in DBCP pooling against postgresql. It works just fine under openjpa 2.1.1 but when I try to upgrade to 2.2.0 it fails.
Here's my persistence.xml: <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"; version="1.0"> <persistence-unit name="quux-postgresql" transaction-type="RESOURCE_LOCAL"> <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> <class>org.example.Foo</class> <properties> <property name="openjpa.ConnectionDriverName" value="org.postgresql.Driver"/> <property name="openjpa.ConnectionURL" value="jdbc:postgresql://localhost/foo"/> <property name="openjpa.ConnectionUserName" value="foo"/> <property name="openjpa.ConnectionPassword" value="foo"/> <property name="openjpa.jdbc.DriverDataSource" value="dbcp"/> <property name="openjpa.jdbc.DBDictionary" value="postgres"/> <property name="openjpa.Log" value="DefaultLevel=TRACE"/> <property name="openjpa.DynamicEnhancementAgent" value="false"/> <property name="openjpa.RuntimeUnenhancedClasses" value="unsupported"/> </properties> </persistence-unit> </persistence> My unit test hardly starts before it fails: public class FooServiceTest { @Test public void canPersist() { EntityManagerFactory factory = Persistence.createEntityManagerFactory("quux-postgresql"); EntityManager em = factory.createEntityManager(); } } When I remove the line with pooling config, "DriverDataSource=dbcp", non-pooled connectivity works and the test passes, so there is nothing wrong with my database conection or the postgresql driver as far as I can tell. And as mentioned, if i instead keep the dbcp flag and downgrade to 2.1.1, the configuration above again works fine. I have tried various dependency combinations. With and without a explicit dependency on commons-dbcp 1.4, and with the openjpa and the openjpa-all artifacts. No difference. What seems strange is that I get the following error message at the end of the stacktrace: NoSuchMethodException: org.apache.openjpa.jdbc.schema.DBCPDriverDataSource.newInstance() <openjpa-2.2.0-r422266:1244990 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: There were errors initializing your configuration: <openjpa-2.2.0-r422266:1244990 fatal user error> org.apache.openjpa.util.UserException: A connection could not be obtained for driver class "org.postgresql.Driver" and URL "jdbc:postgresql://localhost/foo".
