從wsgen工具生成wsdl時出錯

Question

我正在用wsgen工具的幫助來嘗試wsdl生成。我已經認可了jaxb-api.jar和jaxws-api.jar文件。

我有一個圖書館TestTo具有AS

public class TestingTo implements Serializable{ 
    public String name; 
} 

這TestTO庫包含在Web服務項目TestingTo類。

我的WebService是如下─

@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; 
    } 
} 

當我運行Ant腳本WSGEN我收到以下錯誤 -

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 

現在我修改我的web服務作爲

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

當我執行螞蟻腳本我得到錯誤 -

    [exec] Exception in thread "main" java.lang.ArrayStoreException: sun.reflec

欣賞如果有人能讓我知道需要做什麼才能成功生成wsdl。

感謝， Adish

我usualy利用CXF作爲SOAP實現和Maven項目配置，請參閱鏈接末（有一個示例項目下載）。但我的猜測是，你必須設置訪問類型，請TestingTo類這樣的（見javadoc）：

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