hi there! i am using drools 5.1 snapshot release. i have built up the following application: * first the source files are parsed and a knowledgebase is created * the application has multiple service-objects * each service object gets a reference to the same knowledgebase * each service creates a StatefulKnowledgeSession in its constructor, and then adds its global variables to the session. * after all services are created, the startService method of each service is called. * within this method there is the following code: new Thread( new Runnable() { public void run() { ksession.fireUntilHalt(); } } ).start(); ksession.startProcess(servicename, params); the problem is: if i run only 1 service everything works fine. when running more than 1 services i cannot access the global variables from my rules or processes anymore. anyone has an idea whats the reason for that behavior? Thanks a lot in advance! tom -- Neu: GMX Doppel-FLAT mit Internet-Flatrate + Telefon-Flatrate für nur 19,99 Euro/mtl.!* http://portal.gmx.net/de/go/dsl02
