wsgen和App Engine

我试图执行wsgen命令来创建一个Web服务。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"

而且出现这个错误：警告：对于javax.jdo.annotations类文件：在类型“javax.jdo.annotations.Persisten”无法找到标注方法“valueStrategy（）”。持久未找到。错误：找不到类文件com.example.prototipo21.Greeting 1错误 1警告错误：编译失败，错误应该已报告

我认为这个问题可以我整合数据存储应用在一个Web服务应用程序中，所以我的类有不同的注释。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;

....

你知道我是什么意思？任何想法都会非常有用！谢谢！

这些都是我的命令，整个跟踪：

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"

误差与你所编写的代码没有问题。问题在于类路径。如果您检查错误，你可以清楚地看到：

找不到类文件com.example.prototipo21.Greeting1

修复你的类路径，使类是提供给WSGEN，你可能提前获得了一步，绊倒在下一组错误:)祝你好运

嗯，我已经改变了JDK的路径，现在在CMD的错误是：警告：apt工具及其相关API的计划在下一个主要的JDK版本中被删除[....更多警告...]错误：无法为注释类型javax.jdo.annotations创建声明。首要的关键。错误：无法为annontation类型javax.jdo.annotation.Persistent [...]创建声明。任何想法？？谢谢！！ =） –

你能发布完整的错误吗？细节不足以说明任何内容 –

是的，我编辑我的主要问题添加逗号和警告和错误，请看看那里，请！谢谢！！ –

我有同样的错误。你得到这个错误的原因是你必须给wsgen一个GAE所使用的库的引用。

只需修改类路径以包含其他jar文件即可。请注意，在Unix中，我们使用冒号“：”来分隔目录，而在Windows中我们使用分号“;”。

（只需更改相应的目录路径）

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' 
resourcedir='./war' 
outsourcedir='./src' 
outdir='./war/WEB-INF/classes' 
wsgen -cp "$clpth" -wsdl -keep -r "$resourcedir" -d "$outdir" -s "$outsourcedir" $class
