Question

添加ejb.jar后，我收到此错误

        javax.naming.NoInitialContextException: Cannot instantiate class: com.ibm.websphere.naming.WsnInitialContextFactory [Root exception is java.lang.ClassNotFoundException: com.ibm.websphere.naming.WsnInitialContextFactory]
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:657)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288)
at javax.naming.InitialContext.init(InitialContext.java:223)
at javax.naming.InitialContext.<init>(InitialContext.java:175)

但是如果我在Java控制台应用程序中运行相同的代码，它会被执行，我在控制台中获取值，但是当我通过将它与我的Web应用程序集成来运行相同的代码时，它会抛出我上面提到的错误。 / p>

          public  String process(String message, int start) {
          System.out.println("from process method");
          String result = "Unable to Process";
          String ejbClientUrl = DBPropertiesLoader.EJBCLIENT_URL;
            System.out.println("Connecting : " + ejbClientUrl);
          try {

         System.getProperties().put("java.naming.factory.initial", "com.ibm.websphere.naming.WsnInitialContextFactory");
         System.getProperties().put("java.naming.provider.url", DBPropertiesLoader.TI_EJB_URL);


         System.getProperties().put("java.naming.provider.url", ejbClientUrl);

         Context ctx = new InitialContext();
         Object ejbObject = ctx.lookup("ejb/EnigmaServiceAccess");
         System.out.println("EJB Object : "+ejbObject);

这是我的QueryBuilder.java类。我只在我尝试加载上下文的地方调用此类的进程方法：

    int num = 0;
    int count = 0;
    while (resultSet.next()) {

        try {

            num++;
            count = resultSet.getInt("SNO");

            ArrayList<InvoiceCustomer> list = new ArrayList<InvoiceCustomer>();
            list.add((InvoiceCustomer) bp.toBean(resultSet, InvoiceCustomer.class));

            TFinvdtoHandler tfinv = new TFinvdtoHandler();
            sRequestItems.add(tfinv
                    .createTFinvdtoRequest(list));
            if (num % 1 == 0) {

                xmlToPost = MessageUtil.xmlServiceRequest(
                        sRequestItems, "TFINVNEW");
                logger.debug(xmlToPost);

                System.out
                        .println("**Sending data to TI Plus through EJB Client***"
                                + "\n");
                finalResult = TIPlusEJBClient.process(xmlToPost, count);

                if (!finalResult.equals("Unable to Process")) {

                    List<ServiceResponse> serviceResponses = MessageUtil
                            .processResponse(finalResult);
                    for (ServiceResponse serviceResponse : serviceResponses) {
                        // System.out.println("**Response Status***"
                        // +serviceResponse.getResponseHeader().getStatus());

如何解决＆＃34;无法实例化类：com.ibm.websphere.naming.WsnInitialContextFactory＆＃34;在Java？
