[appengine-java] How to read an owned hierarchy fast?
Hi, What is the fastest way to read an owned hierarchy? I've created an app with GWT as front end and GAE as back end with Java and JDO. In the beginning I read a hierarchy of owned entities to the client. I read 154 small entitities in total and that takes about 1s on the server and the latency as shown in the log is 1.2s. Is that the expected performance or could I do better? When looking in the appstat for the app, there are 29 runQuery calls which is almost the same number as the number of entites that are not leaves. I also get this warning and two other simular in the log: org.datanucleus.store.appengine.MetaDataValidator warn: Meta-data warning for gb.shop.client.model.Shop.departments: The datastore does not support joins and therefore cannot honor requests to place related objects in the default fetch group. The field will be fetched lazily on first access. Regards Gunnar -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] cannot load JDOPersistenceManager
Hi, I am getting following error when calling pmf.getPersistenceManager(): org.datanucleus.exceptions.NucleusUserException: No available StoreManager found for the datastore URL key . 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.jdo.NucleusJDOHelper.getJDOExceptionForNucleusException(NucleusJDOHelper.java: 354) at org.datanucleus.jdo.JDOPersistenceManagerFactory.freezeConfiguration(JDOPersistenceManagerFactory.java: 544) at org.datanucleus.jdo.JDOPersistenceManagerFactory.getPersistenceManager(JDOPersistenceManagerFactory.java: 576) at org.datanucleus.jdo.JDOPersistenceManagerFactory.getPersistenceManager(JDOPersistenceManagerFactory.java: 557) Strange thing is it is showing url is although I have set it to appengine -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
