cmusphinx - Null pointer exception config file -

i trying familiarize myself sphinx dissecting config file.

unfortunately, haven't been able compile. did using same class contents of helloworld example, removed config file listed , replaced 1 shown in http://cmusphinx.sourceforge.net/sphinx4/javadoc/edu/cmu/sphinx/util/props/doc-files/configurationmanagement.html

i getting null pointer exception , can't figure out why. imported sphinx4.jar, wsj_8gau....jar, js.jar, , jsapi.jar. know reading config file. compiling correctly when left as

helloworld.class.getresource("helloworld.config.xml"). below code slight changes made.

package speechcapture; //import edu.cmu.sphinx.demo.helloworld.helloworld; import edu.cmu.sphinx.frontend.util.microphone; import edu.cmu.sphinx.recognizer.recognizer; import edu.cmu.sphinx.result.result; import edu.cmu.sphinx.util.props.configurationmanager;  public class capturespeech {     public void speechtolist(string[] args){            configurationmanager cm;              if (args.length > 0) {                 cm = new configurationmanager(args[0]);             } else {                 cm = new configurationmanager("testing.config.xml");             }              recognizer recognizer = (recognizer) cm.lookup("recognizer");             recognizer.allocate(); //where error occurs              // start microphone or exit if program if not possible             microphone microphone = (microphone) cm.lookup("microphone");             if (!microphone.startrecording()) {                 system.out.println("cannot start microphone.");                 recognizer.deallocate();                 system.exit(1);             }              system.out.println("say: (good morning | hello) ( bhiksha | evandro | paul | philip | rita | )");              // loop recognition until program exits.             while (true) {                 system.out.println("start speaking. press ctrl-c quit.\n");                  result result = recognizer.recognize();                  if (result != null) {                     string resulttext = result.getbestfinalresultnofiller();                     system.out.println("you said: " + resulttext + '\n');                 } else {                     system.out.println("i can't hear said.\n");                 }          }           }    } 

recognizer null on line:

        recognizer recognizer = (recognizer) cm.lookup("recognizer");         recognizer.allocate(); //where error occurs 

because component named "recognizer" missing in config xml file. when update xml file check code in sync.
