我正在開發一個項目，我正在開發一個Web服務，使用谷歌翻譯API將英語翻譯成法語。我已經成功地創建了服務器。但是當我運行我的客戶端時出現錯誤。我正在爲項目使用Java，Eclipse，Axis2和Tomcat。 這是我的服務器代碼：Web服務錯誤（谷歌翻譯API）WSDL錯誤Java Eclipe Axis2
package com.GTWS;
import com.gtranslate.Language;
import com.gtranslate.Translator;
public class GoogleTranslateClass {
public String toFrench(String sentence){
Translator translate = Translator.getInstance();
String textF = translate.translate(sentence, Language.ENGLISH, Language.FRENCH);
return textF;
}
}
請注意，我使用的是外部谷歌翻譯爲宗旨API JAR。然後我創建Web服務並讓它運行。 Eclipse將創建WSDL文件是：

然後我去創造僅僅使用軸基於Eclipse的Web客戶端並創建代理文件。我創建代理類的一個對象，並調用toFrench的方法，如：
package com.GTWS;
import java.rmi.RemoteException;
import com.GTWS.*;
public class GTtester {
public static void main(String[] args) throws RemoteException {
// TODO Auto-generated method stub
GoogleTranslateClassPortTypeProxy gtp = new GoogleTranslateClassPortTypeProxy();
System.out.println(gtp.toFrench("hi there"));
}
}
後來我得到的錯誤：
