Hello ian,
Thanks for your reply.
BTW, im using eclipse 3.5 (Galileo) and had just configured the
datasource for mysql successfully.
I edited my configuration like this(commented out storeManagerType)
and the connectionURL:
I had also replaced the datanucleus jars with version 1.1.5 as its the
version GAE uses.
I used Mysql server 5.1.
<persistence-manager-factory name="mysql">
<property name="javax.jdo.PersistenceManagerFactoryClass"
value="org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory"/
>
<property name="datanucleus.ConnectionDriverName"
value="com.mysql.jdbc.Driver"/>
<property name="datanucleus.ConnectionURL" value="jdbc:mysql://
localhost:3306/jdo"/>
<property name="datanucleus.ConnectionUserName" value="root"/>
<property name="datanucleus.ConnectionPassword" value="[*****]"/>
<property name="datanucleus.appengine.autoCreateDatastoreTxns"
value="true"/>
<property name="datanucleus.autoStartMechanism" value="None"/>
<property name="datanucleus.autoCreateSchema" value="true"/>
<property name="datanucleus.validateTables" value="true"/>
<property name="datanucleus.validateConstraints" value="true"/>
<property name="datanucleus.validateColumns" value="true"/>
<property name="datanucleus.DetachAllOnCommit" value="true"/>
<property name="datanucleus.maxFetchDepth" value="1"/>
<!-- <property name="datanucleus.storeManagerType" value="rdbms"/>
-->
</persistence-manager-factory>
But still the error persist.
Here is the error logs:
Caused by: org.datanucleus.exceptions.NucleusUserException: No
available StoreManager found for the datastore URL key "jdbc". Please
make sure you have all relevant plugins in the CLASSPATH (e.g
datanucleus-rdbms?, datanucleus-db4o?), and consider setting the
persistence property "datanucleus.storeManagerType" to the type of
store you are using e.g rdbms, db4o
at org.datanucleus.store.FederationManager.initialiseStoreManager
(FederationManager.java:197)
at org.datanucleus.store.FederationManager.<init>
(FederationManager.java:70)
at org.datanucleus.ObjectManagerFactoryImpl.initialiseStoreManager
(ObjectManagerFactoryImpl.java:153)
at
org.datanucleus.jdo.JDOPersistenceManagerFactory.freezeConfiguration
(JDOPersistenceManagerFactory.java:526)
... 51 more
Here is my PMF.java class. I guess there are still more configurations
to make. I created the database jdo. I guess there will be no need to
create a table?
public final class PMF {
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("mysql");
//JDOHelper.getPersistenceManagerFactory("postgresql");
//JDOHelper.getPersistenceManagerFactory("transactions-
optional");
private PMF() {}
public static PersistenceManagerFactory get() {
return pmfInstance;
}
}
Hope someone could help me with this.
Thanks,
ivanceras
