Question

我在wsgen工具的帮助下尝试wsdl生成。我已经认可了jaxb-api.jar和jaxws-api.jar文件。

我有一个TestTo库，它有TestingTo类AS

public class TestingTo implements Serializable{
    public String name;
}

此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，我收到以下错误 -

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
     [exec] Result: 1

现在我将我的网络服务修改为

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

当我执行ant脚本时，我得到错误 -

欣赏如果有人能让我知道需要做什么才能成功生成wsdl。

谢谢， Adish

我通常使用CXF作为SOAP实现和maven进行项目配置，请参阅最后的链接（有一个示例项目要下载）。但我的猜测是你必须像这样设置TestingTo类的访问者类型（见javadoc）：

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