我正在使用一个库，其结构如下

在此处输入图像描述

我正在将vn.hus.nlp.tokenizer-4.1.1.jar文件添加到库中，Add JAR/Folder并将其余部分复制到我的项目中。当我使用java应用程序时它工作。但是当我尝试 servlet 时，我在使用这个库时遇到了问题。

我的项目

在此处输入图像描述

Servlet：类Filter扩展 HttpServlet

try {          
       VietTokenizer v = new VietTokenizer(); // error here !
       JSONObject jso=new JSONObject();
       jso.put("status","A");
       jso.put("label","true");
       out.print(jso);
    } finally {            
        out.close();
    }

我认为，当您部署时，库不会在库中导入右键单击您的 Web 项目，选择Libraries。在Complie选项卡中，确保您的库已被选中！

你错过了commons-cli图书馆。例如，您可以在此处找到它，包含在 lib 文件夹的存档中：

https://code.google.com/p/vntagger-gate-plugin/source/browse/lib/vn.hus.nlp.tokenizer-4.1.1.jar

您可以像添加第一个库一样添加它。
