Re: [rules-users] drools 6 equivalent of addKnowledgePackages

There are several different ways of doing it, but here is a snippet to help creating an in-memory kjar with default kbases and ksessions: public static byte[] createKJar(KieServices ks, ReleaseId releaseId, String pom, String... drls) { KieFileSystem kfs = ks.newKieFileSystem(); if( pom != null ) { kfs.write("pom.xml", pom); } else { kfs.generateAndWritePomXML(releaseId); } KieResources kr = KieServices.getResources(); for (int i = 0; i < drls.length; i++) { if (drls[i] != null) { kfs.write( kr.newByteArrayResource( drls[i].getBytes() ).setSourcePath("my/pkg/drl"+i+".drl") ); } } KieBuilder kb = ks.newKieBuilder(kfs).buildAll(); if( kb.getResults().hasMessages( org.kie.api.builder.Message.Level.ERROR ) ) { for( org.kie.api.builder.Message result : kb.getResults().getMessages() ) { System.out.println(result.getText()); } return null; } InternalKieModule kieModule = (InternalKieModule) ks.getRepository() .getKieModule(releaseId); byte[] jar = kieModule.getBytes(); return jar; } Please note that you usually don't need the byte[] back, so you can ignore everything after the last 3 lines of the code. Also, the error check in the snippet is just printing to sysout. You should handle this accordingly in your application. Hope it helps.
