我在eclipse中运行我的动态Web项目。 我得到这个错误为什么我不知道

但是，如果我在java控制台应用程序中运行相同的代码，它将被执行，我在我的控制台中获取值，但是当我通过将它与我的Web应用程序集成运行相同的代码时，它会抛出我上面提到的错误

  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);

Answer 2

它将在WebSphere中作为Web应用程序运行时没有任何问题。

如果要从Tomcat运行它，则需要将以下jar添加到应用程序中，但仅适用于Tomcat： com.ibm.ws.ejb.thinclient_x.yzjar和com.ibm.ws.orb_8.5.0.jar 。 如果您的WebSphere受到保护，您还应该查看此页面运行IBM Thin Client for Enterprise JavaBeans ，因为您可能在以后遇到SSL问题。
