drools 5.0.1 generating fact types as non-serializable classes
by cjohnston
Hello, I have declared a fact type in a drl file:
package com.innovativeinfo.amacus.drools.model
declare AmacusUser
id : long
timeZone : String
end
which according to
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/ht...
should result in a generated class that implements Serializable.
However when I try to persist the KnowledgeSession, I get:
Caused by: java.io.NotSerializableException:
com.innovativeinfo.amacus.drools.model.AmacusUser
at
java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)

Is there a configuration option I need to set to generate Serializable fact
types? Or is this a bug in 5.0.1? I realize I can define "fact types" myself
as classes in Java, but would prefer to use the shortened syntax if
possible.
Any advice appreciated.
Cheers
