在Glassfish上部署gwt-dev.jar（NoClassDefFoundError）

Question

在我的GWT应用程序的服务器端，我使用org.apache.commons.httpclient包中的类。这些类可方便地包装在GWT发布的gwt-dev.jar中。我在战争的WEB-INF/lib中包括这个罐子（沿着gwt-servlet.jar）。 当部署在GlassFish中产生war文件并调用页面，我得到的服务器日志以下异常（和RPC失败）

NoClassDefFoundError: org/apache/commons/httpclient/HttpException 

我应该怎么做，这样的GlassFish发现在gwt-dev.jar类？

- 更多细节 - 例如GWT的

作为重现问题的SSCCE，我已经修改类GreetingServiceImpl：

import org.apache.commons.httpclient.HttpException; 
public String greetServer(String input) throws IllegalArgumentException { 
     try { 
      if(input.equals("hello")){ 
       throw new HttpException(); 
      } 
     } catch (HttpException e) { 
      throw new RuntimeException(e); 
     } 
     ... the rest of the GWT example app

您应该添加公地httpclient.jar（或HttpClient的-4.0.1.jar - 取决于分配）到您的'WEB-INF/lib目录'。
