Re: [rules-users] Inserting Facts from Json Format
Hi,
I'm facing the same problem.
The following code works fine if i know upfront wht the object should be:
ObjectMapper mapper = new ObjectMapper();
FactType type = kbase.getFactType("eu.mc2bis.events",
"DeviceEventDeclared");
System.out.println ("Actual type:" + type.getFactClass() );
Object event;
try
{
event = mapper.readValue(arg2, type.getFactClass());
session.insert(event);
session.fireAllRules();
}
catch (JsonParseException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (JsonMappingException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
So actually this means that the class is available from the classloader now
when i do the same using BatchExecutionHelper.newJSonMarshaller() i get a
.the following exception:
Exception in thread "main"
com.thoughtworks.xstream.converters.ConversionException:
eu.mc2bis.events.DeviceEventDeclared : eu.mc2bis.events.DeviceEventDeclared
---- Debugging information ----
message : eu.mc2bis.events.DeviceEventDeclared

line number : -1
class[1] : org.drools.command.runtime.BatchExecutionCommandImpl
converter-type[1] :

Any help would be appreciated,
Regards,
