从wsgen工具生成wsdl时出错

Question

我正在尝试在wsgen工具的帮助下生成wsdl。我已经认可了jaxb-api.jar和jaxws-api.jar文件。

我有一个库TestTo，它有TestingTo类AS

public class TestingTo implements Serializable{
    public String name;
}

TestTO库包含在webservice项目中。

我的WebService如下-

@WebService()
public class IcfInfra {
    @WebMethod(operationName = "printTest")
    public TestingTo printTest(@WebParam(name = "string") String string)
    {
        TestingTo to = new TestingTo();
        to.name = string;
        System.out.println(string);
        return to;
    }
}

当我为Wsgen运行Ant脚本时，我得到以下错误-

main:
     [exec] Note:       ap round: 1
     [exec] Problem encountered during annotation processing;
     [exec] see stacktrace below for more information.

     [exec] error: compilation failed, errors should have been reported

现在我把我的webservice修改为

@WebService()
@XmlSeeAlso({
    TestingTo.class
})
public class IcfInfra {
   ...
}

当我执行ant脚本时，我得到错误-

感谢如果有人能让我知道需要做什么才能成功地生成wsdl。

谢谢,Adish

我通常使用CXF作为SOAP实现，并使用maven进行项目配置，请参阅末尾的链接(有一个示例项目可供下载)。但是我的猜测是，您必须像这样为TestingTo类设置访问器类型(参见javadoc):

@XmlAccessorType( XmlAccessType.FIELD )
public class TestingTo implements Serializable{
    public String name;
}
