オブジェクトをJAX WSに渡す

パラメータとしてjava.lang.Objectを使用するWebサービスのメソッドを呼び出すことのできるシナリオを強調しています。次のようにWebサービスのエンドポイントがある http://java.sun.com/developer/technicalArticles/J2SE/jax_ws_2/オブジェクトをJAX WSに渡す

：

私はTomcatの7

、作成、展開、およびWebサービスにアクセスするためにはNetbeans 7.1を使用していますが、私はで与えられた手順に従っ

package com.metrows; 

import javax.jws.WebService; 
import javax.jws.WebMethod; 
import javax.jws.WebParam; 

/** 
* 
* @author 298790 
*/ 
@WebService(serviceName = "NewWebService") 
public class NewWebService { 

    /** 
    * This is a sample web service operation 
    */ 
    @WebMethod(operationName = "hello") 
    public String hello(@WebParam(name = "name") String txt) { 
     return "Hello " + txt + " !"; 
    } 

    /** 
    * Web service operation 
    */ 
    @WebMethod(operationName = "sendObjParam") 
    public Object sendObjParam(@WebParam(name = "paramObj") Object paramObj) { 
     //TODO write your implementation code here: 
     System.out.println("In NewWebService.sendObjParam(...) "+paramObj); 

     return paramObj; 
    } 

/** 
    * Web service operation 
    */ 
    @WebMethod(operationName = "passCustomParams") 
    @Oneway 
    public void passCustomParams(@WebParam(name = "tenant") Tenant tenant) { 

     System.out.println("In NewWebService.passCustomParams(...) : tenant = " + tenant); 

     System.out.println(": " + tenant.getMap()); 
    } 

}

テナントは、以下の通りである：

次のように

package com.valueobjects; 

import java.util.HashMap; 

/** 
* 
* @author 298790 
*/ 
public class Tenant { 

    private String tenantId; 
    private String tenantName; 
    private HashMap map; 

    public String getTenantId() { 
     return tenantId; 
    } 

    public void setTenantId(String tenantId) { 
     this.tenantId = tenantId; 
    } 

    public String getTenantName() { 
     return tenantName; 
    } 

    public void setTenantName(String tenantName) { 
     this.tenantName = tenantName; 
    } 

    public HashMap getMap() { 
     return map; 
    } 

    public void setMap(HashMap map) { 
     this.map = map; 
    } 


}

クライアントである：サーバー起動時に

package metro_ws_client; 

/** 
* 
* @author 298790 
*/ 
public class Metro_WS_Client { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) { 
     // TODO code application logic here 
     System.out.println(hello("Aao Thakur !!!")); 

     Tenant tenant = new Tenant(); 
     tenant.setTenantId("lnt"); 
     tenant.setMap(new Tenant.Map()); 

     passCustomParams(tenant); 
     Object o = new Object(); 
     //String s = "Shot"; 
     sendObjParam(o); 
    } 


    private static String hello(java.lang.String name) { 
     metro_ws_client.NewWebService_Service service = new metro_ws_client.NewWebService_Service(); 
     metro_ws_client.NewWebService port = service.getNewWebServicePort(); 
     return port.hello(name); 
    } 

    private static Object sendObjParam(java.lang.Object paramObj) { 
     com.metrows.NewWebService_Service service = new com.metrows.NewWebService_Service(); 
     com.metrows.NewWebService port = service.getNewWebServicePort(); 
     return port.sendObjParam(paramObj); 
    } 

private static void passCustomParams(com.metrows.Tenant tenant) { 
     com.metrows.NewWebService_Service service = new com.metrows.NewWebService_Service(); 
     com.metrows.NewWebService port = service.getNewWebServicePort(); 
     port.passCustomParams(tenant); 
    } 
}

（それが反復的であるようではない、完全なスタックトレース）、私は次の例外を取得：

私は、標準のJavaオブジェクトを渡すことができる方法についての私を導いてください。非プリミティブメンバーを持つオブジェクトをWebサービスに追加する

出典

webservicesを使用する場合は、オブジェクトのXML表現、つまり文字列表現を持つことを意味します。あなたがプリミティブ（SOAPがサポートしている）を使用していない場合、どのような文字列表現が必要ですか？私は逐次化を考えることができるJavaの世界では、これはあなたが期待するものですか？ – jambriz

Webサービスクライアントメソッドに渡すオブジェクトは、JAXBによって直列化可能である必要があります。最低限これは、@XMLRootElementと注釈を付ける必要があることを意味します。もちろん、あなたはnew Object()を渡すことはできません（とにかく便利ではありません）。
