How do I access kcontext in custom workItem?
public void executeWorkItem(WorkItem i, WorkItemManager m) {
// I want kcontext variable here
}
Thanks.

Importing data in drools applications..
by Mahalakshmi
hi,
I am new to drools and am really confused with the follwing:
1.
how I can go about adding a data set and modifying the data set based on my
rules.
Can I add a data set to my drools-guvnor itself and apply my rules to it and
check? Does the data set need to be in an excel file?
For example. I want to store 2 columns ( customer name & billingnumber)
2.
How can i import my drools project into eclipse and work with the data set?
Because when I tried doing that I could not see the rules I created in
eclipse. It just showed me the first import package statements.
Also I am unable to import the whole project at once.
Can somebody please guide me or give me some documentation I can refer to? I
am just going about in circles.
3.
How can I go about creating a front end for the application??
Any help highly appreciated :)
thank you.

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)
at
java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:302)
at
org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy.write(SerializablePlaceholderResolverStrategy.java:37)
at
org.drools.marshalling.impl.OutputMarshaller.writeFactHandle(OutputMarshaller.java:278)

at
org.drools.marshalling.impl.DefaultMarshaller.marshall(DefaultMarshaller.java:117)
at
org.drools.persistence.session.JPASessionMarshallingHelper.getSnapshot(JPASessionMarshallingHelper.java:76)
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
