Encoding set in constructor not taking effect --------------------------------------------- Key: DROOLS-3402 URL: https://issues.redhat.com/browse/DROOLS-3402 Project: Drools Issue Type: Bug Affects Versions: 7.13.0.Final Reporter: Barnabás Kurucz Assignee: Tibor Zimanyi Priority: Major In my drl file, I'm using German characters such as Umlauts or ß. Thus, I am setting the encoding to UTF-8 with the overloaded constructor when creating the Resource for the Kie File System. However, after firing the rules on the inserted Fact Drools does not seem to apply the specified encoding. I insert the fact, and if the condition is true to that fact it should modify the Action1 (String) attribute of the fact to "Rückfrage" and return the modified fact. However, when I look at the retrieved bean's Action1 attribute I am seeing "Rückfrage" instead of "Rückfrage". I tried both UTF-8 and ISO-8859-1 encoding. Any ideas what's wrong? Drools 7.13 *KieSessionGenerator*: public KieSessionGenerator() { KieServices kieServices = KieServices.Factory.get(); KieFileSystem kieFileSystem = kieServices.newKieFileSystem(); kieFileSystem.write(ResourceFactory.newClassPathResource(drlFile, "UTF-8")); KieBuilder kieBuilder = kieServices.newKieBuilder(kieFileSystem); kieBuilder.buildAll(); KieModule kieModule = kieBuilder.getKieModule(); KieContainer kieContainer = kieServices.newKieContainer(kieModule.getReleaseId()); kieSession = kieContainer.newKieSession(); } *Snippet from DRL:* rule "813" when $bean : Bean(longDesc == "Infektion") then $bean.setAction1("Rückfrage"); end *Inserting the fact:* public Bean lookupBean(Bean bean) { kieSessionGenerator.getKieSession().insert(bean); kieSessionGenerator.getKieSession().fireAllRules(); return bean; } UPDATE: After some further investigation it looks the issue can be reproduced only when the default system encoding is set to CP-1252. Since the system default was CP-1252, the JVM was running with that encoding and the KIE Resource also had used this encoding, even though I set UTF-8 in its conctructor. Once I changed the system default to UTF-8, the special characters (ä, etc.) were shown correctly.
