Java BPEL 复合应用程序：此 wsdl 文件中没有可用的有效 xml 模式元素

Question

当我部署我的 BPEL 复合应用程序时，我收到错误：

错误：在“参数”部分，属性元素的值“tns:hello”是 此 wsdl 文件中不是可用的有效 xml 架构元素。 ： 指定 元素属性的有效架构元素值。

这是发生此错误的 CASA xml 文件：

Answer 1

在部署时，WSDL 被解析，系统必须能够访问引用的 XSD 模式才能读取类型。现在描述的方式是，XML 模式位于您的本地主机上。您的服务器必须启动并侦听端口 8080，并且不应阻止系统访问该地址。

确保 xsd 架构可在以下位置访问：

http://localhost:8080/Retailer/RetailerService?xsd=1。

如果它可用但仍未部署，您可以尝试将从架构中引用的所有类型直接复制到该部分中的 WSDL 中以代替该部分。
