How to select a Hibenrate configuration file for web application/junit?

Question

Dear all,
I am using hibernate for a web application.
I have two configuration files: one ("hibernate-jta.cfg.xml") uses a data source and the other ("hibernate.cfg.xml") directly uses jdbc.
private static String CONFIG_FILE = "hibernate-jta.cfg.xml"; private static String CONFIG_FILE_WITHOUT_DATASOURCE = "hibernate.cfg.xml";
When I deplyed my applcation to an application server, I need to use the first one. When I run junit test, I need to use the second one.
How can I design a mecanism to switch between the two configuration files according the the case: web application or java stand alone application?
Configuration cfg = new Configuration(); cfg.configure(CONFIG_FILE);
Thanks.

My solution is to add a new public method "initFactoryForJunit() " in the Static singleton.
In the junit test, this method will be invoked in order to load a second configuration file.
public class ThreadsafeSessionFactory {
     private static Logger log = Logger
               .getLogger(ThreadsafeSessionFactory.class);
     private static String CONFIG_FILE = "hibernate-jta.cfg.xml";
     private static String CONFIG_FILE_FOR_JUNIT = "hibernate.cfg.xml";
     private static final Configuration cfg = new Configuration();
     private static org.hibernate.SessionFactory sessionFactory;
     public static SessionFactory getInstance() {
          log.info("getInstance()");
          if (sessionFactory == null) {
               ThreadsafeSessionFactory.initFactory();
          return sessionFactory;
     /*public synchronized Session openSession() {
          log.debug("openSession()");
          return sessionFactory.getCurrentSession();
     public synchronized Session getCurrentSession() {
          log.debug("getCurrentSession()");
          return sessionFactory.getCurrentSession();
     private static void initFactory() {
          log.debug("initFactory()");
          if (sessionFactory == null) {
               try {
                    Configuration cfg = new Configuration();
                    cfg.configure(CONFIG_FILE);
                    String factoryJndiName = cfg
                              .getProperty(Environment.SESSION_FACTORY_NAME);
                    if (factoryJndiName != null) {
                         log.debug("using jndi factory");
                         cfg.buildSessionFactory();
                         sessionFactory = (SessionFactory) (new InitialContext())
                                   .lookup(factoryJndiName);
                    } else {
                         log.info("using default factory");
                         sessionFactory = cfg.buildSessionFactory();
                         log.info("after using default factory");
               } catch (Exception ex) {
                    ex.printStackTrace();
                    log.error("failed creating session factory");
                    throw new HibernateException(
                              "initFactory(): failed initializing configuration");
     public static void initFactoryForJunit() {
          log.debug("initFactory()");
          if (sessionFactory == null) {
               try {
                    Configuration cfg = new Configuration();
                    cfg.configure(CONFIG_FILE_FOR_JUNIT);
                    String factoryJndiName = cfg
                              .getProperty(Environment.SESSION_FACTORY_NAME);
                    if (factoryJndiName != null) {
                         log.debug("using jndi factory");
                         cfg.buildSessionFactory();
                         sessionFactory = (SessionFactory) (new InitialContext())
                                   .lookup(factoryJndiName);
                    } else {
                         log.info("using default factory");
                         sessionFactory = cfg.buildSessionFactory();
                         log.info("after using default factory");
               } catch (Exception ex) {
                    ex.printStackTrace();
                    log.error("failed creating session factory");
                    throw new HibernateException(
                              "initFactory(): failed initializing configuration");
     public static void close() {
          if (sessionFactory != null)
               sessionFactory.close();
          sessionFactory = null;
