不正确的值：未知命名空间 http://www.w3.org/2001/xmlschema

Question

当我厌倦了在 sap 中创建客户端代理并提供服务提供商 web 服务时，我正在尝试在 sap 中使用外部 Web 服务（WSDL 文件）进行数据集成 URL http://172.31.3.48:8717/?wsdl it gives me proxy generation error it giving me a error of "liberary haldler exception" " incorrect value: unknown namespace http://www.w3.org/2001/xmlschema" . I am facing this error in just in this file which provided by my services provider , except this all of the wsdl file generated successfully one the file which generated suceesfully is this http://www.webservicex.net/stockquote.asmx?WSDL.

我们将不胜感激。

Given below is my Wsdl file which giving me error..

这个元素似乎有些不对劲。直接引用架构的元素对我来说很奇怪 - 我从未见过这样的结构：

    <s:element name="GetDataResponse">
        <s:complexType>
            <s:sequence>
                <s:element minOccurs="0" maxOccurs="1" name="GetDataResult">
                    <s:complexType>
                        <s:sequence>
                            <s:element ref="s:schema" />
                            <s:any />
                        </s:sequence>
                    </s:complexType>
                </s:element>
            </s:sequence>
        </s:complexType>
    </s:element>

我已经在 Eclipse 中验证了您的 WSDL - 查看 Eclipse 对此 WSDL 的说明：

解析组件时出错 's:schema'。检测到 's:schema' 在命名空间“http://www.w3.org/2001/XMLSchema”中，但无法从架构文档 'file:///WSDLTEST.wsdl' 中引用来自此命名空间的组件。如果这是不正确的命名空间，可能需要更改 's:schema' 的前缀。如果这是正确的命名空间，则应将适当的 'import' 标记添加到 'file:///WSDL.wsdl'.

尝试完全删除 <s:element ref="s:schema" /> 行，看看它是否适合您。或者按照请求 GetData 的方式逐个元素地描述序列。
