我在构建JAXB绑定方案集时遇到了一些问题,它使我有点慌乱。这是有问题的模式(它可能只是模式之一,在这个特殊的版本):被忽略的Jaxb绑定文件
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xml="http://www.w3.org/XML/1998/namespace" targetNamespace="http://www.w3.org/XML/1998/namespace">
<attribute name="lang" type="language">

<attribute ref="xml:space"/>
</attributeGroup>
XJC声称,上述声明的属性已经在别处声明:
parsing a schema...

做一点研究会导致我相信问题是我需要一个绑定文件来解决重复的属性....我有一个:
<jaxb:bindings version="1.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jaxb:extensionBindingPrefixes="xjc">
<jaxb:bindings schemaLocation="../../gml/3.1.1/smil/xml-mod.xsd" node="/xs:schema">
<jaxb:bindings node="//xs:attribute[@name='lang']">
<jaxb:property name="langAttribute"/>
</jaxb:bindings>
<jaxb:bindings node="//xs:attribute[@name='space']">
<jaxb:property name="spaceAttribute"/>
</jaxb:bindings>
<jaxb:bindings node="//xs:attributeGroup[@name='specialAttrs']">
<jaxb:property name="specialAttrsAttribute"/>
</jaxb:bindings>
</jaxb:bindings>
然而问题仍然存在。带或不带绑定文件的错误消息都是相同的。我知道该文件正在使用,因为如果我搞乱了节点选择器的xpath,我会收到一条错误消息。这就像xjc知道绑定文件在那里,但忽略它。
下面是构建失败,绑定的命令行:
C:\tools\jaxb-ri-20110512\bin\xjc -episode ..\..\..\common.ogc -d ..\..\..\src -p com.ogc.bindings -b ..\..\..\bindings.xsd -catalog ..\..\..\ogc.cat -extension sosAll.xsd
我有两个JDK6本地JAXB(2.0)和JAXB 2.2.4想这(我装的是JAXB-api.jar文件中认可的目录)
谢谢!那就是诀窍 – user1005939
