JEExplorer

If you're looking for an administration utility to help manage files and directories on your server file system, then JEExplorer is the software for you. It can either be used as a standalone application or integrated into an existing Java/J2EE web application.

One of the key highlights of JeExplorer is its ease of integration. With just a single JSP and jar file, there are no external dependencies that require installation. Moreover, JEExplorer has no specific requirements for the client when running, so there's no need for any additional installation of JavaScript, applets, or anything of the sort.

You can install JEExplorer on any Java server, such as Apache Tomcat, JBoss, and more. It's packed as a Java/J2EE war file which means that it can be easily installed without any added hassle.

To integrate JEExplorer with an existing web application, all you need to do is drop the JSP file anywhere in the web application. JEExplorer is well suited for any web administrator looking to streamline their file management.
