简单nusoap请求返回java.lang.nullPointerException
我正在尝试使用JAX-WS发布的Web服务，这是我以前从未使用过的，请耐心等待。 在本地环境中执行nusoap调用时，它提供所有请求的数据。然而，一旦我将java应用程序部署到我的开发环境中，它就会从服务器端返回一个空指针异常 下面是我的代码片段（我很乐意提供您可能需要的任何进一步信息，因为我以前从未使用过JAX WS）。提前感谢 XML文件，发布在下面的示例url中（相关部分） /*内容*/简单nusoap请求返回java.lang.nullPointerException,java,web-services,jax-ws,Java,Web Services,Jax Ws,我正在尝试使用JAX-WS发布的Web服务，这是我以前从未使用过的，请耐心等待。 在本地环境中执行nusoap调用时，它提供所有请求的数据。然而，一旦我将java应用程序部署到我的开发环境中，它就会从服务器端返回一个空指针异常 下面是我的代码片段（我很乐意提供您可能需要的任何进一步信息，因为我以前从未使用过JAX WS）。提前感谢 XML文件，发布在下面的示例url中（相关部分） /*内容*/ This XML file does not appear to have any style inf
