Hot Deployment from Eclipse · Oct 8, 12:48 PM by Krishna Prasad V

If you are used to hot deployment for Tomcat using “My Eclipse”, then you dont have to go for a commercial plugin for Eclipse to do hot deployment! Surprised…? Configure your eclipse as below and see the results:

1. Download “File Sync” plugin from http://andrei.gmxhome.de/filesync/index.html

2. Download “Sysdeo Tomcat” plugin from http://www.sysdeo.com/eclipse/tomcatplugin

3. Install both the plugins in to your eclipse>>plugin directory (If you need help in installing, see the install guide provided for the plugins in their respective homepages)

4. Configure your File Sync to synchronize the files to your application deployed in Tomcat.

5. Hot Deployment configured!! Enjoy :)
