I still get the error. My PMF class is
public final class PMF {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("datanucleus.properties");
private PMF() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
My ./war/WEB-INF/classes/META-INF/jdoconfig.xml is like this
<?xml version="1.0" encoding="utf-8"?>
<jdoconfig xmlns="http://java.sun.com/xml/ns/jdo/jdoconfig";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="http://java.sun.com/xml/ns/jdo/jdoconfig";>
<persistence-manager-factory name="transactions-optional">
<property name="javax.jdo.PersistenceManagerFactoryClass"
value="org.datanucleus.api.jdo.JDOPersistenceManagerFactory"/>
<property name="javax.jdo.option.ConnectionURL" value="appengine"/>
<property name="javax.jdo.option.NontransactionalRead" value="true"/>
<property name="javax.jdo.option.NontransactionalWrite"
value="true"/>
<property name="javax.jdo.option.RetainValues" value="true"/>
<property name="datanucleus.appengine.autoCreateDatastoreTxns"

<property name="datanucleus.appengine.datastoreEnableXGTransactions"

<property name="datanucleus.persistenceByReachabilityAtCommit"
value="false"/>
<property name="javax.jdo.option.PersistenceUnitName" value="true"/>
</persistence-manager-factory>
</jdoconfig>
And my ./src/main/resources/datanucleus.properties
javax.jdo.option.ConnectionDriverName=org.apache.derby.jdbc.EmbeddedDriver
javax.jdo.option.ConnectionURL=jdbc:derby:RECORDTABLE;create=true
javax.jdo.option.ConnectionUserName=user
javax.jdo.option.ConnectionPassword=password
datanucleus.autoCreateTables=true
datanucleus.autoCreateSchema=true
datanucleus.autoCreateColumns=true
datanucleus.autoCreateConstraints=true
datanucleus.RetainValues=true
I did something wrong in these settings.
