[rules-users] Help needed - Repository not getting initialised?

[Praveen]

Hi,

Repository is not getting initialised, throws NPE.
Please advise.
TIA.

public static Repository repository;

        public static Session getSession() throws Exception {
            return getSession(true);
        }

        public static synchronized Session getSession(boolean erase) {
            try {
                if (repository == null) {

                    if (erase) {
                        File repoDir = new File("repository");
                        System.out.println("DELETE test repo dir: "
                                + repoDir.getAbsolutePath());
                        RepositorySessionUtil.deleteDir(repoDir);
                        System.out.println("TEST repo dir deleted.");
                    }

                    JCRRepositoryConfigurator config = new
JackrabbitRepositoryConfigurator();
                    String home = System
                            .getProperty("guvnor.repository.dir");
                                      
                    repository = config.getJCRRepository(home);

                    Session testSession = repository
                            .login(new SimpleCredentials("alan_parsons",
                                    "password".toCharArray()));

                    RulesRepositoryAdministrator admin = new
RulesRepositoryAdministrator(
                            testSession);
                    if (erase && admin.isRepositoryInitialized()) {

                        admin.clearRulesRepository();
                    }
                    config.setupRulesRepository(testSession);
                    return testSession;
                } else {
                    return repository.login(new SimpleCredentials(
                            "alan_parsons", "password".toCharArray()));
                }
            } catch (RepositoryException e) {
                throw new IllegalStateException(e);
            }

        }
        
        public static void main(String [] args) throws Exception{
        	getSession();
        }


Below is the exception..
