WSDL文件上的JAX-WS错误:"解析组件的错误:schema'"

Question

错误

我在Java项目中使用wsimport来生成三个SOAP Web服务的源代码.前两个工作正常:我使用JAX-WS Maven插件来获取WSDL文件并生成相应的Java源文件.

一个Web服务失败; 我收到以下错误:

[jaxws:wsimport]
Processing: /home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl

src-resolve.4.2: Error resolving component 's:schema'. It was detected that 's:schema' is in namespace 'http://www.w3.org/2001/XMLSchema', but components from this namespace are not referenceable from schema document 'file:/home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl#types?schema1'. If this is the incorrect namespace, perhaps the prefix of 's:schema' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:/home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl#types?schema1'.

罪魁祸首

这个WSDL文件与工作的文件之间的区别在于错误消息中第80,127和142行中注明的行:

<s:element ref="s:schema" />

注意:wsdl文件的根元素定义了"s"命名空间:

xmlns:s="http://www.w3.org/2001/XMLSchema" 

---

我试过的

我做了我的研究.看起来其他人有类似的问题,从"只是不使用<s:element ref="s:schema" />"到"使用导入标签"的解决方案,到一些不可知的解决方案,显然在旧的java.net论坛上(在它被删除之前,现代亚历山大图书馆的Java知识纵火).

• 我已经尝试将以下import语句放在包含问题标记的元素内:<s:import namespace="http://www.w3.org/2001/XMLSchema" schemaLocation="http://www.w3.org/2001/XMLSchema.xsd" />.wsimport给了我一个新的错误:

  此错误中引用的第108行和第109行是:(第184-5行,第199-200行相似)

  <s:any minOccurs="0" maxOccurs="unbounded" namespace="http://www.w3.org/2001/XMLSchema" processContents="lax" />
  <s:any minOccurs="1" namespace="urn:schemas-microsoft-com:xml-diffgram-v1" processContents="lax" />
  

• 我已经尝试将jaxws-maven-plugin从1.10升级到2.2.同样的问题.

• 这是一个可能的解决方案 - 我试图找出如何使用JAX-WS Maven插件实现它.任何提示？

结论

有任何想法吗？您需要的任何进一步信息？为简洁起见,我省略了pom.xml和Service.asmx.wsdl文件,但如果其中包含更多重要信息,则可以包含它们.

谢谢!

附加物

这是另一个有同样问题的人,如果这有助于任何潜在的回答者. 这是另一个类似的问题. 我真的不明白这篇文章,但似乎暗示我必须手动解析SOAP XML!恐怖!

我通过调整Vivek Pandey的方法来解决这个问题,同时更新到jaxws-maven-plugin 2.2.我将在此重申它的后代:

摘要

把这个XJB自定义文件(见下文),在默认绑定文件目录下,并设置wsimport的绑定,并http://www.w3.org/2001/XMLSchema.xsd.

XJB定制

上面提到的XML文件xsd.xjb的内容应该放在你的默认绑定文件目录中,如下所示(归功于Kohsuke):

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
          xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
          version="2.0">

  <globalBindings>
    <xjc:simple />
  </globalBindings>

  <bindings scd="~xsd:complexType">
    <class name="ComplexTypeType"/>
  </bindings>

  <bindings scd="~xsd:simpleType">
    <class name="SimpleTypeType"/>
  </bindings>

  <bindings scd="~xsd:group">
    <class name="GroupType"/>
  </bindings>

  <bindings scd="~xsd:attributeGroup">
    <class name="AttributeGroupType"/>
  </bindings>

  <bindings scd="~xsd:element">
    <class name="ElementType"/>
  </bindings>

  <bindings scd="~xsd:attribute">
    <class name="attributeType"/>
  </bindings>
</bindings>

POM

这是我的POM文件的相关部分,其中包含更改:

Answer 2

对于Nick的解决方案,您可能需要将这两个jvm参数添加到pom.xml中,以便在遇到这些错误时:

org.xml.sax.SAXParseException; systemId:http://www.w3.org/2001/XMLSchema.xsd ; lineNumber:67; columnNumber:11; 外部DTD:无法读取外部DTD"XMLSchema.dtd",因为由于accessExternalDTD属性设置的限制而不允许"http"访问.

[WARNING] schema_reference:无法读取架构文档"xml.xsd",因为由于accessExternalSchema属性设置的限制而不允许"http"访问.http://www.w3.org/2001/XMLSchema.xsd第91行

只需将它们添加到您的pom.xml即可

-Djavax.xml.accessExternalDTD=all
-Djavax.xml.accessExternalSchema=all

<vmArgs>
    <vmArg>-Djavax.xml.accessExternalDTD=all</vmArg>
    <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
</vmArgs>
