Question

我想用JSF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，我得到错误。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faces-initialization完全不起作用，则会发生这种情况 - 请确保正确包含基本面应用程序所需的所有配置设置，并且包含所有必需的lib。还要检查Web应用程序和容器的日志记录输出是否有异常！如果你这样做并且一无所获，那么错误可能是因为您使用了一些特殊的Web容器，这些容器不支持通过TLD文件注册上下文侦听器，并且您的web.xml中没有设置上下文侦听器。典型的配置看起来像这样; org.apache.myfaces.webapp.StartupServletContextListener

引起： java.lang.IllegalStateException - 没有为此应用程序配置的工厂。如果faces-initialization完全不起作用，则会发生这种情况 - 请确保正确包含基本面应用程序所需的所有配置设置，并且包含所有必需的lib。还要检查Web应用程序和容器的日志记录输出是否有异常！如果你这样做并且一无所获，那么错误可能是因为您使用了一些特殊的Web容器，这些容器不支持通过TLD文件注册上下文侦听器，并且您的web.xml中没有设置上下文侦听器。典型的配置看起来像这样; org.apache.myfaces.webapp.StartupServletContextListener

任何想法如何解决问题？

    This parameter tells MyFaces if javascript code should be allowed in

    If javascript is allowed, command_link anchors will have javascript code

当我点击：

Answer 1

为了避免某些错误，例如＆＃34;没有为此应用程序配置的工厂＆＃34;使用CXF动态客户端和JSF，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);

Answer 2

您引用的错误与CXF无关，而是与org.apache.myfaces无关。

如果从服务器返回所有内容，那么你的网址是错误的？wsdl。浏览该URL是否在普通浏览器中生成WSDL文件？

您可以在CXF用户邮件列表上获得更好的调试帮助。这不是一个问题，而是一个需要大量来回的诊断问题。

为什么我在CXF中出现此错误
