我显然不了解如何在 WSDL 的 XML 中正确使用名称空间。有些东西没有点击。我剪掉了一段我们的 WSDL 来演示这个问题。请参阅下面的工作 WSDL。
当我使用 wsimport 从中生成代码时，它可以工作。当我尝试使用我定义的类型时，它没有。我在另一个问题中看到评论说：
For example, one does not have to use a prefix for the items defined in the schema,
that are later on referenced elsewhere in the same file (e.g. a global simpleType
used as a type for an attribute or element).
当我读到它时，我想我明白了。但我显然没有。
我使用的 JAX-WS 是：“JDK 6 中的 JAX-WS RI 2.1.6”
我在 WSDL 中添加了这个：
<xsd:complexType name="Void">
<xsd:sequence>
</xsd:sequence>
</xsd:complexType>
我将 HelloRequest 元素更改为：
<xsd:element name="HelloRequest" type="Void" />
我得到下面的错误。
“不必为架构中定义的项目使用前缀，这些项目稍后会在同一文件的其他地方引用......”
那句话是什么意思？我不认为这意味着我认为它意味着什么......

运行 wsimport 的错误是：
[WARNING] src-resolve.4.1: Error resolving component 'Void'. It was detected that 'Void' has no namespace, but components with no target namespace are not referenceable from schema document 'http://snip/LMSService.woa/wa/hellowsdl#types?schema1'. If 'Void' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'Void' has no namespace, then an 'import' without a "namespace" attribute should be added to 'http://snip/LMSService.woa/wa/hellowsdl#types?schema1'.
