在JSP上创建目录树结构

我最近遇到了Java DefaultMutableTreeNode类.我想知道是否有任何类似的类/技术可用于Servlet/JSP.

I recently came across the Java DefaultMutableTreeNode class. I was wondering if there is any similar classes/technology available for Servlets/JSPs.

我正在开发一个Web应用程序，其数据库表存储了各种文件的绝对路径名，我的servlet应该从表中读取路径名并将其显示为目录树结构.

I am working on a web application for which a database table stores absolute path name for various files, my servlet is supposed to read the path names from the table and display them as a directory tree structure.

非常感谢.任何建议将不胜感激.

Thanks so much in advance. Any advise will be appreciated.
