Hi, can anybody tell me how to do re-load the specific set of rules when they are changed without reloading other files. This is the business requirement. How multiple threads are accessed in Drools. I want to know if for one request, I load the rule file and then close the session, then what should be done for second thread which wants the same drools file to access. I do not want to load every time. If you say the drools file should be loaded at application start. Then How can I load the drool files which are changed in between. Thanks. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-re-load-the-specific-set-of-rule... Sent from the Drools: User forum mailing list archive at Nabble.com.
