我正在尝试执行 wsgen 命令来创建 Web 服务。我的命令行是：

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"

并出现此错误：警告：在类型'javax.jdo.annotations.Persisten'中找不到注释方法'valueStrategy（）'：找不到javax.jdo.annotations.Persistent的类文件。error: 找不到 com.example.prototipo21.Greeting 的类文件 1 error 1 warning error: 编译失败，应该报错

我认为问题可能是我正在将数据存储应用程序集成到 Web 服务应用程序中，因此我的班级有不同的注释。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;

……

你知道我的意思？？任何想法都会非常有用！！谢谢！

这些是我的命令和整个跟踪：

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

I was having the same error. The reason why you are getting this error is that you have to give wsgen a reference to the libraries that GAE are using as well.

Just modify the classpath to include the other jar files. Note that in Unix we use colon ":" to separate directories and in Windows we use semi-colon ";".

(Just change the directory path accordingly)

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

该错误与您编写的代码没有问题。问题在于类路径。如果您检查错误，您可以清楚地看到：

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

修复您的类路径，以便该类可用于 wsgen 并且您可能会领先一步并在下一组错误中绊倒:) 祝你好运
