my Java code here :
public static void main(String[] args) {
String url = "http://ip:8080/drools-wb/maven2wb/org/mydemo/myDemo/1.0/myDemo-1.0.jar";
// make sure you use "LATEST" here!
ReleaseIdImpl releaseId = new ReleaseIdImpl("org.mydemo", "myDemo", "1.0");
KieServices ks = KieServices.Factory.get();
ks.getResources().newUrlResource(url);
KieContainer kieContainer = ks.newKieContainer(releaseId);
// check every 5 seconds if there is a new version at the URL
KieScanner kieScanner = ks.newKieScanner(kieContainer);
kieScanner.start(5000L);
// alternatively:
// kieScanner.scanNow();
Scanner scanner = new Scanner(System.in);
while (true) {
runRule(kieContainer);
System.out.println("Press enter in order to run the test again....");
scanner.nextLine();
}
}
private static void runRule(KieContainer kieKontainer) {
StatelessKieSession kSession = kieKontainer.newStatelessKieSession("testSession");
kSession.setGlobal("out", System.out);
kSession.execute("testRuleAgain");
}
Can anyone please help me, i am new to drools and spent almost 2 days to solve this issue.

Answer 1

It might be the url you are using, try changing it to:
http://ip:8080/drools-wb/maven2/org/mydemo/myDemo/1.0/myDemo-1.0.jar
i.e. maven2 NOT maven2b
then try that in a web browser. If you need authentication then this works for me when Drools is hosted on Tomcat and has basic authentication turned on.
KieServices ks = KieServices.Factory.get();
KieResources resources = ks.getResources();
UrlResource urlResource = (UrlResource) resources.newUrlResource(url);
urlResource.setUsername("admin");
urlResource.setPassword("admin");
urlResource.setBasicAuthentication("enabled");
I found this blog post very helpful, it might help you even though you are not using Spring.
