使用jaxb schemagen创建XSD

Question

我正在学习JAXb 2.0并且对它很新颖。

我试图基于使用schemagenŸPOJO类来生成XSD和简单的类它工作正常，但是当我的类包含refrence其他类

schemagen是给我下面的错误是针对同一错误跟踪

注解处理中遇到的问题; 请参阅下面的堆栈跟踪以获取更多信息。

下面

是

schemagen位于以下位置的我的文件夹结构的详细

C:\Users\Desktop\jaxb\jaxb-ri-20101119\bin 

在此基础上我试图生成XSD

我的Java类是在以下位置

C:\Users\Desktop\jaxb\jaxb-ri-20101119\bin\src\com\tr\model\destination 

Destination.java

而距目的地还有类被refrenced所有其他类本身是以下结构

C:\Users\Raisonne\Desktop\jaxb\jaxb-ri-20101119\bin\src\com\raisonne\tr\model 

我知道这个问题是与类路径的设置里面，但我无法弄清楚豪设置正确的类路径这种情况下

我想系统的CLASSPATH变量设置为

C:\Users\Raisonne\Desktop\jaxb\jaxb-ri-20101119\bin\src\com\raisonne\tr\model as well other 2 mentioned in my post but nothing worked out. 

值任何一个可以帮助我的设置CLASSPATH schemagen。

在此先感谢

看来你已经设置你的类的包声明

com.tr.model.address 

它应该是从你的目录结构

com.tr.model.destination
