I recently upgraded to the Europa version of Eclipse (3.3) and I noticed that my PiecesOfFlare (POF) plugin stopped working. So after 2 years, we now have a new release. The POF plugin is a small plugin that enables you to hit the save button in eclipse, and then have the updated (jsp, js, php, etc) file being copied to another destination outside your source tree. When I say outside, think to your webserver or appserver on the same file system, or even a to a remote machine (using scp).
You can download the plugin from sourceforge, or you can use the update site at http://piecesofflare.sourceforge.net/updates/.
