Add custom jape file in GATE source code

Question

Could anyone please guide me how can I create one custom JAPE file and configure it with GATE source code. I have tried with following code and getting exception like "Error while parsing the grammar :" and "Neither grammarURL or binaryGrammarURL parameters are set!"

     try{
             Document doc = new DocumentImpl();
              String str = "This is test.";
              DocumentContentImpl impl = new DocumentContentImpl(str);
              doc.setContent(impl);
          System.setProperty("gate.home", "C:\\Program Files\\GATE_Developer_7.1"); 
          Gate.init();
          gate.Corpus corpus = (Corpus) Factory
            .createResource("gate.corpora.CorpusImpl");
          File gateHome = Gate.getGateHome();
          File pluginsHome = new File(gateHome, "plugins");
          Gate.getCreoleRegister().registerDirectories(new File(pluginsHome, "ANNIE").toURI().toURL());  

          Transducer transducer = new Transducer();
             transducer.setDocument(doc);
transducer.setGrammarURL(new URL("file:///D:/misc_workspace/gate-7.1-build4485-SRC/plugins/ANNIE/resources/NE/SportsCategory.jape"));
transducer.setBinaryGrammarURL(new URL("file:///D:/misc_workspace/gate-7.1-build4485-SRC/plugins/ANNIE/resources/NE/SportsCategory.jape"));

LanguageAnalyser jape = (LanguageAnalyser)Factory.createResource(
                  "gate.creole.Transducer", gate.Utils.featureMap(
                          "grammarURL", "D:/misc_workspace/gate-7.1-build4485-SRC/plugins/ANNIE/resources/NE/SportsCategory.jape",
                          "encoding", "UTF-8"));

Thank you Ian. These training courses material is helpful. But my problem was different and I have solved it. The following code snap is how to use custom jape file in GATE. Now my custom jape file is capable to produce new annotation.

 System.setProperty("gate.home", "C:\\Program Files\\GATE_Developer_7.1"); 
  Gate.init();

  ProcessingResource token = (ProcessingResource)   Factory.createResource("gate.creole.tokeniser.DefaultTokeniser",Factory.newFeatureMap());



 String str = "This is a test. Myself Abhijit Nag sport";
   Document doc = Factory.newDocument(str);


  gate.Corpus corpus = (Corpus) Factory.createResource("gate.corpora.CorpusImpl");
  corpus.add(doc);
  File gateHome = Gate.getGateHome();
  File pluginsHome = new File(gateHome, "plugins");

  Gate.getCreoleRegister().registerDirectories(new File(pluginsHome, "ANNIE").toURI().toURL());  


 LanguageAnalyser jape = (LanguageAnalyser)Factory.createResource(
              "gate.creole.Transducer", gate.Utils.featureMap(
                      "grammarURL", "file:///D:/misc_workspace/gate-7.1-build4485-SRC/plugins/ANNIE/resources/NE/SportsCategory.jape","encoding", "UTF-8"));
      jape.setCorpus(corpus);
      jape.setDocument(doc);
      jape.execute();

  pipeline = (SerialAnalyserController) Factory.createResource("gate.creole.SerialAnalyserController",
                Factory.newFeatureMap(), Factory.newFeatureMap(),"ANNIE");
              initAnnie();
              pipeline.setCorpus(corpus);
              pipeline.add(token);
              pipeline.add((ProcessingResource)jape.init());
              pipeline.execute();
      AnnotationSetImpl ann = (AnnotationSetImpl) doc.getAnnotations();
      System.out.println(" ...Total annotation "+ann.getAllTypes());
