[rules-users] Inserting Facts from Json Format

[Mark Proctor]

See BatchExecutionHelper:
http://docs.jboss.org/drools/release/5.3.0.Final/droolsjbpm-integration-docs/html_single/index.html#d0e830
public class BatchExecutionHelper {
     public static XStream newJSonMarshaller() {

Use out camel integration to work with JSON, as it hides a lot of the 
complexity. Also make sure you understand the "command" stuff, which is 
in the integration docs too.
