Re: [rules-users] problem with drools

You need to bind your fact to a variable, so that you can call the getFileOld method from a non static context. Also, I think you'd be better to use != rather than the 'not' keyword ('not' should be read 'doesn't exist' which doesn't work if you want to bind a value). So your rule should be something like: rule "files not equal" when $file : FileData(fileOld != fileNew) then System.out.println("files are not equal"); difference($file.getFileOld(),$file.getFileNew()); end -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-problem-with-drools-tp40284...
