我正在开发一个使用谷歌翻译api将英语翻译成法语的web服务项目。我已经成功地创建了服务器。但是，当我运行我的客户端，我得到一个错误。我在这个项目中使用了Java、Eclipse、Axis2和Tomcat。这是我的服务器代码:
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;
}
}
请注意，我使用的是一个外部的google translate api jar。然后创建web服务并使其运行。Eclipse创建如下WSDL文件:

然后我继续使用Axis在eclipse上创建web客户端，它创建代理文件。我创建了代理类的一个对象，并调用toFrench的方法，如下所示:
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"));
}
}
之后我得到错误:

您需要将mail-1.4.jar和activation-1.1.jar添加到您的类路径(WEB-INF/lib)中。因为您在wsdl文件中有mime类型。
