Hi I wrote code for creating RuleBase. But I got error at retrieving URL resource by passing ruleFile to the getResource() method.It is returning null. How to get the URL resource. I posted the sample code which i have written for creating RuleBase. public RuleBase createRuleBase() throws Exception { if(rules==null) { throw new Exception("No rules provided for Engine"); } ruleBase = RuleBaseFactory.newRuleBase(); PackageBuilder builder = new PackageBuilder(); for(String ruleFile : rules) { System.out.println("Rule is "+ruleFile); //prints the ruleFile URL resource = this.getClass().getResource(ruleFile); //gets the URL resource of the ruleFile if(resource==null) { System.err.println("Could not find resource: "+ruleFile); continue; } File file = new File(this.getClass().getResource(ruleFile).getPath()); if(!file.exists()) { System.err.println("Could not find rule file: "+file.getPath()); continue; } builder.addPackageFromDrl(new FileReader(file.getPath())); } org.drools.rule.Package pkg = builder.getPackage(); ruleBase.addPackage(pkg); return ruleBase; } My Packages are not adding to RuleBase.It is returning null. How to add the packages to ruleBase.Please suggest me Thanks -- View this message in context: http://drools.46999.n3.nabble.com/How-to-add-Packages-to-RuleBase-tp36534...

Hi Esteban, Thank you so much for your quick Response. Here ruleFile is a .drl file and i printed the file name before this statement. "URL resource = this.getClass().getResource(ruleFile);" Thanks -- View this message in context: http://drools.46999.n3.nabble.com/How-to-add-Packages-to-RuleBase-tp36534...
