Hi all,
I'm trying to convert an existing JPA application to run on App
Engine, but when I try to run the application, I got the following
exception:
java.lang.RuntimeException: java.io.NotSerializableException:
org.datanucleus.store.appengine.jpa.DatastoreEntityManagerFactory
at
com.google.apphosting.runtime.jetty.SessionManager.serialize(SessionManager.java:
387)
(...)
Caused by: java.io.NotSerializableException:
org.datanucleus.store.appengine.jpa.DatastoreEntityManagerFactory
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:
1173)
The application runs in maven2, so I don't know if this may be a
problem caused by old lib versions. The declared dependecies are:
<dependency>
<groupId>com.google.appengine.orm</groupId>
<artifactId>datanucleus-appengine</artifactId>
<version>1.0.5</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-jpa</artifactId>
<version>1.1.5</version>
<scope>runtime</scope>
</dependency>
The datastore classes were not supposed to be compatible with the App
Engine runtime restrictions?
Any tips about how to solve this problem?
Thanks in advance,
Joaquim Oliveira
