Hi guys, I have an simple application running on top of Spring using JPA for Google AppEngine (GAE).
There's no compilation error, but when i load my application using Google AppEngine Development Server, i got runtime error saying that my Entity class is not enhanced!! Which kinda confusing me actually, because i deployed to another container (tomcat) and this Entity classes is running smoothly (of course i need to modify the persistence.xml accordingly) Here is my persistence.xml : <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence"; version="1.0"> <persistence-unit name="myDB"> <provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</ provider> <properties> <property name="datanucleus.NontransactionalRead" value="true"/> <property name="datanucleus.NontransactionalWrite" value="true"/> <property name="datanucleus.ConnectionURL" value="appengine"/> </properties> </persistence-unit> </persistence> My Entity class : @Entity @Table(name = "audit_trail") public class AuditTrail implements java.io.Serializable { private static final long serialVersionUID = 1L; private Integer id; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id", nullable = false) public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } private String message; @Column(name = "message") public String getMessage() { return message; } public void setMessage(String msg) { this.message = msg; } } And this is the error code: 10-07-01 11:18:22 ERROR [] [main] MetaData - Found Meta-Data for class com.somecompany.demo.model.AuditTrail but this class is not enhanced!! Please enhance the class before running DataNucleus. org.datanucleus.exceptions.NucleusUserException: Found Meta-Data for class com.somecompany.demo.model.AuditTrail but this class is not enhanced!!
