java - 为什么我在 CXF 中收到此错误

Question

我想使用 CXF 在 JSF 中创建动态 Web 服务调用程序。但是当我加载这个简单的代码时，我收到错误。代码:

JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl");

错误:

没有为此应用程序配置工厂。如果面部初始化根本不起作用，就会发生这种情况 - 确保正确包含基本面部应用程序所需的所有配置设置，并且包含所有必需的库。还要检查 Web 应用程序和容器的日志输出是否有任何异常!如果您这样做了但什么也没找到，则错误可能是由于您使用了一些特殊的 Web 容器，这些容器不支持通过 TLD 文件注册上下文监听器，并且您的 web.xml 中未设置上下文监听器。典型的配置如下所示； org.apache.myfaces.webapp.StartupServletContextListener

知道如何解决这个问题吗？

    This parameter tells MyFaces if javascript code should be allowed in

    If javascript is allowed, command_link anchors will have javascript code

为了避免使用 CXF 动态客户端和 JSF 出现“没有为此应用程序配置工厂”之类的错误，您必须执行以下操作:

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl");
Thread.currentThread().setContextClassLoader(classLoader);
