[rules-users] Inserting Facts from Json Format

[ekzl at yahoo.com]

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 ----

converter-type[1]   :

version             : null

Any help would be  appreciated,

Regards,
