wsgen和App Engine

我試圖執行wsgen命令來創建一個Web服務。我的命令行是：wsgen和App Engine

PATH=%path%;C:\Program Files\Java\jdk1.6.0_24\bin 
wsgen -cp ".\war\WEB-INF\classes" -wsdl -keep -r ".\war" -d ".\war\WEB-INF\classes" -    s ".\war" "com.example.prototipo21.Greeting"

而且出現這個錯誤：警告：對於javax.jdo.annotations類文件：在類型「javax.jdo.annotations.Persisten」無法找到標註方法「valueStrategy（）」。持久未找到。錯誤：找不到類文件com.example.prototipo21.Greeting 1錯誤 1警告錯誤：編譯失敗，錯誤應該已報告

我認爲這個問題可以我整合數據存儲應用在一個Web服務應用程序中，所以我的類有不同的註釋。例如：

@WebService 
public class Greeting { 

@PrimaryKey 
@Persistent (valueStrategy = IdGeneratorStrategy.IDENTITY) 
private Key key; 

@Persistent 
private User author;

...

@WebMethod 
public Key getKey() { 
    return key; 
} 
@WebMethod 
public User getAuthor(){ 
    return author;

....

你知道我是什麼意思？任何想法都會非常有用！謝謝！

這些都是我的命令，整個跟蹤：

c:\Users\...\Desktop\....\Eclipse\Prototipo_21>PATH=%pa 
th%;C:\Program Files\Java\jdk1.7.0_03\bin 

c:\Users\...\Desktop\....\Eclipse\Prototipo_21>wsgen -c 
p ".\war\WEB-INF\classes" -wsdl -keep -r ".\war" -d ".\war\WEB-INF\classes" -s " 
.\war" "com.example.prototipo21.Greeting" 

warning: The apt tool and its associated API are planned to be

誤差與你所編寫的代碼沒有問題。問題在於類路徑。如果您檢查錯誤，你可以清楚地看到：

找不到類文件com.example.prototipo21.Greeting1

修復你的類路徑，使類是提供給WSGEN，你可能提前獲得了一步，絆倒在下一組錯誤:)祝你好運

嗯，我已經改變了JDK的路徑，現在在CMD的錯誤是：警告：apt工具及其相關API的計劃在下一個主要的JDK版本中被刪除[....更多警告...]錯誤：無法爲註釋類型javax.jdo.annotations創建聲明。首要的關鍵。錯誤：無法爲annontation類型javax.jdo.annotation.Persistent [...]創建聲明。任何想法？？謝謝！！ =） –

你能發佈完整的錯誤嗎？細節不足以說明任何內容 –

是的，我編輯我的主要問題添加逗號和警告和錯誤，請看看那裏，請！謝謝！！ –

我有同樣的錯誤。你得到這個錯誤的原因是你必須給wsgen一個GAE所使用的庫的引用。

只需修改類路徑以包含其他jar文件即可。請注意，在Unix中，我們使用冒號「：」來分隔目錄，而在Windows中我們使用分號「;」。

（只需更改相應的目錄路徑）

class=com.sample.MyWebService 
clpth='./war/WEB-INF/classes:/Applications/eclipse_jee/plugins/com.google.appengine.eclipse.sdkbundle_1.7.0/appengine-java-sdk-1.7.0/lib/opt/user/datanucleus/v2/jdo-api-3.1-SNAPSHOT-20110926.jar:/Applications/eclipse_jee/plugins/com.google.appengine.eclipse.sdkbundle_1.7.0/appengine-java-sdk-1.7.0/lib/user/appengine-api-1.0-sdk-1.7.0.jar'
