使用jaxb schemagen創建XSD

Question

我正在學習JAXb 2.0並且對它很新穎。

我試圖基於使用schemagenŸPOJO類來生成XSD和簡單的類它工作正常，但是當我的類包含refrence其他類

schemagen是給我下面的錯誤是針對同一錯誤跟蹤

註解處理中遇到的問題; 請參閱下面的堆棧跟蹤以獲取更多信息。

import com.tr.model.address.BasicAddress;[code] 

下面

是

schemagen位於以下位置的我的文件夾結構的詳細

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

在此基礎上我試圖生成XSD

我的Java類是在以下位置

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

Destination.java

而距目的地還有類被refrenced所有其他類本身是以下結構

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

我知道這個問題是與類路徑的設置裏面，但我無法弄清楚豪設置正確的類路徑這種情況下

我想系統的CLASSPATH變量設置爲

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. 

值任何一個可以幫助我的設置CLASSPATH schemagen。

在此先感謝

Umesh製作

Answer 1

看來你已經設置你的類的包聲明

com.tr.model.address 

它應該是從你的目錄結構

com.tr.model.destination
