Tool for removing unused classes?

Thread view:

My team needs to get rid of classes in a large application that are no
longer used. There are around 1500 class files in total and we estimate

that about 25% of these classes are no longer used. Is there some type
of tool that can identify classes that have been run during a certain
time period or some way to identify these classes other then removing
them from a build and getting compliation errors? We are using Eclipse
as a development tool and Tomcat as a server.

You can try Autojar

http://autojar.sourceforge.net/

This application analyses the dependencies starting from one or
more classes.

I have integrated Autojar in the experimental beta release
of Fat-Jar Eclipse Plug-In:

Semantic Designs has a tool for removing "dead" (e.g., unreferenced)
code from a set of Java classes.
