From what I can see from your code, it looks ok, but to know what is happening we would need the audit log and some example rule that you would expect to fire, but is not being fired.Edson
2010/6/30 Jean-Philippe Steinmetz <jeanphilippe@trilogystudios.com>Hello all,
I’d like to get Drools working in such a way that it is always running and I can just stream new events into the runtime and have it execute rules against them. From what I can tell I need to use stream mode in order to do this. I’ve got everything set up for how I think it should work (based on what I can decipher from the documentation) but what’s happening is that I’m never getting a hit on the rules I write. I can see the event be asserted but nothing happens.
Here is my set up…
KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
config.setOption(EventProcessingOption.STREAM);
setKnowledgeBase(KnowledgeBaseFactory.newKnowledgeBase(config));
// Create a knowledge agent to pull load the necessary resources
kagent = KnowledgeAgentFactory.newKnowledgeAgent("MyAgenda", getKnowledgeBase());
initResources(kagent);
setKnowledgeBase(kagent.getKnowledgeBase());
getSession().addEventListener(new DebugAgendaEventListener());
getSession().addEventListener(new DebugWorkingMemoryEventListener());
And here is how I start up Drools…
thread = new Thread() {
@Override
public void run() {
getSession().fireUntilHalt();
}
};
thread.run();
I then feed events into the engine like this…
WorkingMemoryEntryPoint stream = getSession().getWorkingMemoryEntryPoint(origin);
stream.insert(event);
I’m obviously missing something in my setup. Any help on understanding how this is supposed to work is greatly appreciated. Again, the goal here is to get Drools in a state that is always running so I can pipe in events to it and have rules execute against them.
Jean-Philippe
