Question

我试图从EurID提供的* .xsd文件中生成Java代码。

目前我收到了几个例外：

Error while parsing schema(s).Location [ file:~/src/main/resources/epp-1.0.xsd{375,32}].
org.xml.sax.SAXParseException; systemId: file:~/src/main/resources/epp-1.0.xsd; lineNumber: 375; columnNumber: 32; src-resolve: Cannot resolve the name 'eppcom:minTokenType' to a(n) 'type definition' component.

[ERROR] Error while parsing schema(s).Location [ file:~/src/main/resources/nsgroup-1.0.xsd{86,42}].
org.xml.sax.SAXParseException; systemId: file:~/src/main/resources/nsgroup-1.0.xsd; lineNumber: 86; columnNumber: 42; src-resolve: Cannot resolve the name 'euridcom:nsgType' to a(n) 'type definition' component.

[ERROR] Error while parsing schema(s).Location [ file:~/src/main/resources/domain-1.0.xsd{94,53}].

对于引用host.xsd文件内容在这里：http://pastebin.com/ZdAGrNXF 和eppcom.xsd在这里：http://pastebin.com/hYSwXQ11

我已经花了5天时间试图找出问题所在 - 尝试不同的maven插件选项组合等。 SO社区是我现在的最后一次机会。提前感谢您的提示。

Answer 1

我改了xsd。添加属性schemaLocation以导入所有xsd架构中的元素。然后生成课程就可以了。

如果我使用目录来解析名称空间，那么我就会遇到一些元素的双重定义问题。

Answer 2

我用过的JRE / JDK并不完整。使用Java EE安装JDK解决了JaxB的问题。

Answer 3

尝试使用epp-1.0.xsd（http://www.iana.org/assignments/xml-registry/schema/epp-1.0.xsd）验证xml并替换

时遇到同样的问题

<import namespace="urn:ietf:params:xml:ns:eppcom-1.0"/>

在带有

的epp-1.0.xsd文件中

<import namespace="urn:ietf:params:xml:ns:eppcom-1.0" schemaLocation="http://www.iana.org/assignments/xml-registry/schema/eppcom-1.0.xsd"/>

解决了这个问题。
