Re: [rules-users] "java.lang.AbstractMethodError: org.jbpm.marshalling.impl.ProcessMarshallerImpl.init" while unmarshalling statefulknowledgesession
This kind of error indicates some confusion between compilation and
execution of the code where this is thrown.
Also, which versions of Drools do you used for marshalling and
unmarshalling? There's no line 287 in the versions of
org.drools.marshalling.impl.PersisterHelper.java available to me.

Hi All,
I ran across an issue while unmarshalling StatefulKnowledgeSession.
First I'm marshalling the session using the following code which works fine
Marshaller marshaller = MarshallerFactory
.newMarshaller(workingMemory.getKnowledgeBase());
File file = new File(
"C:\\Users\\Sumatheja\\workingmemory.info");
FileOutputStream fos = new FileOutputStream(file);
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
marshaller.marshall(baos, workingMemory);
baos.writeTo(fos);
baos.close();
When I try to unmarshall the session using
Marshaller marshaller = MarshallerFactory
.newMarshaller(workingMemory.getKnowledgeBase());
FileInputStream fis = new
FileInputStream("C:\\Users\\Sumatheja\\workingmemory.info");
workingMemory = marshaller.unmarshall(fis);
I'm getting the Error:
java.lang.AbstractMethodError:
