Question

我使用的库有下面的结构

enter image description here

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

我的项目

enter image description here

Servlet：类Filter扩展了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();
    }

json-simple-1.1.1.jar is work well. 谢谢！

Answer 1

您错过了commons-cli库。您可以在此处找到它，包含在lib文件夹中的存档中：

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。

Answer 2

我认为，在部署时，库不会在库中导入右键单击您的Web项目，选择库。在 Complie 标签中，确保您的库已经过检查！

在java servlet netbean中使用库
