Hi All,
I have a deployed running application in following environment GWT 2.5RC1,
GAE 1.7.0, Objectify 3.x
I deleted all previous data from DB. Now for some reason, i changed the
class names of my entities.
All code remains same.
Here i have a entity with new name as follows
@Unindexed
public class PackageEnquiryEntity implements Serializable {
/**
*
*/
private static final long serialVersionUID = -8667552679106180269L;
public PackageEnquiryEntity() {
}
@Id Long id;
@Indexed private String userIdAsEmail;
@Indexed private Date enquiryDate;
I am returning List<PackageEnquiryEntity> through many RPC calls.
Everything works fine in development mode. No issue.
But in production mode on GAE, i am getting SerializationException through
some of RPC calls while some RPC calls works fine with the same entity.
I am confused why it fails in production. Everything was working fine in
production also before changing the class names of entity.
Here are the exception details
javax.servlet.ServletContext log: Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type
'com.pdstechi.commonmodule.shared.holiday.PackageEnquiryEntity' was
not included in the set of types which can be serialized by this
