creating a Directory tree structure on a JSP

Question

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

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.

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

Answer 1

Would you use a jQuery plugin to display your paths as a tree?

jQuery File Tree is a configurable, AJAX file browser plugin for jQuery. You can create a customized, fully-interactive file tree with as little as one line of JavaScript code.

Answer 2

Not out the box. You have to create it yourself or to head to a 3rd party taglib or framework.

Several examples:

• A 3rd party JSP taglib
• A tag of the Struts2 framework
• A tag of a 3rd party JSF component library
• A tag of another 3rd party JSF component library

Answer 3

If you are willing to use a web application framework, you may also consider the Tree-component from Vaadin . See the Sampler for a Tree example, including source code.
