将外部 JAXB 绑定文件应用于从 WSDL 导入的模式元素 [英] Applying external JAXB binding file to schema elements imported from WSDL

问题描述

我的外部绑定文件中的 XPath 表达式无法针对导入到我的 WSDL 中的 XML 模式中的元素.

The XPath expression in my external binding files can't target the elements in my XML schemas which are imported into my WSDL.

如果我进行内联绑定自定义，一切都会运行，但我真的很想拥有外部绑定文件，这样我就不会意外覆盖(刷新)包含我的自定义的文件.

Everything runs if I do inline binding customization but I really wanted to have external binding files that way I never accidentally overwrite(refresh) the files containing my customizations.

我的绑定文件的开头:

<jaxb:bindings
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
    version="2.1">
    <jaxb:bindings schemaLocation="../wsdl/localhost_7001/ExampleSessionBean/ExampleSessionBeanService.wsdl#types?schema1">
        <jaxb:bindings node="//xs:schema[@targetNamespace='urn:myExample']">

我的 WSDL 包含:

My WSDL contains:

<types>
<xsd:schema>
<xsd:import namespace="urn:myExample" schemaLocation="http://localhost:7001/ExampleSessionBean/ExampleSessionBeanService?xsd=1"/>
</xsd:schema>
<xsd:schema>
<xsd:import namespace="http://ejbs/" schemaLocation="http://localhost:7001/ExampleSessionBean/ExampleSessionBeanService?xsd=2"/>
</xsd:schema>
</types>

无论我做什么，XPath 都无法在 xsd:import 的模式中找到任何内容.我得到的错误是:

No matter what I do XPath can't find anything in the xsd:import'ed schemas. The error I get is:

[ERROR] XPath evaluation of "//xs:schema[@targetNamespace='urn:myExample']" results in empty target node

我尝试通过索引号而不是命名空间来访问 xs:schema，但这也不起作用.似乎我的 XPath 表达式无法从导入的架构中访问元素……无论如何要解决这个问题?

I've tried accessing the xs:schema by index number instead of the namespace and that doesn't work either. It seems like my XPath expressions can't reach elements from imported schemas...is there anyway to fix this?

这是在 NetBean 7.2 下开发的 Java SE 7 项目.如果这很重要，我正在使用 NetBeans 来执行我所有的 wsimport 操作，但命令输出对于 RI/Metro 来说看起来相当标准.

This is a Java SE 7 project being developed under NetBean 7.2. I'm using NetBeans to do all my wsimport stuff if that matters but the command output looks fairly standard for RI/Metro.

我发现如果我使用 SCD，我可以得到一个外部绑定文件.此 XPath 示例不起作用:

I figured out that I can get an external binding file to work if I use SCD. This XPath example doesn't work:

<bindings node="//xsd:schema[@targetNamespace='urn:myExample']">
    <bindings node="//xs:complexType[@name='myType']">
        <class name="MyClass"/>
    </bindings>
</bindings>

但是这个 SCD 示例确实如此.

But this SCD example does.

<bindings scd="x-schema::tns" xmlns:tns="urn:myExample">
    <bindings scd="~tns:myType">
        <class name="MyClass"/>
    </bindings>
</bindings>

当使用 wsimport 时 XPath 在 xjb 文件中不起作用但 SCD 起作用，这是已知的事情吗?

Is this a known thing where XPath doesn't work in xjb files when using wsimport but SCD does?

推荐答案

你应该像这样使用它:

<jaxws:bindings node="wsdl:definitions/wsdl:types/xsd:schema[@targetNamespace='http://duke.example.org']">
    <jaxb:schemaBindings>
        <jaxb:package name="fromwsdl.server"/>
    </jaxb:schemaBindings>
</jaxws:bindings>

注意命名空间
