you'd do something like this... in your Java code, instantiate an instance of your logger (of whatever class) import org.apache.commons.Log; // or whatever logger class you are using private Log mylogger = new Log(); then create your command list and add the logger instance as a global: List commands = new ArrayList<Command>(); commands.add(CommandFactory.newSetGlobal("logger", mylogger)); then in your rule you declare the global: global org.apache.commons.Log logger; -- View this message in context: http://drools.46999.n3.nabble.com/drools-server-empty-response-body-tp319...
