Tomcat 4.0-b6 fixes several issues related to reloading, including:
- Changes to JSP pages weren't being recognized in 4.0-b5 (although this
was fixed in recent nightly releases)
- Changes to classes in a JAR file under /WEB-INF/lib were not recognized
- Reloading was not cleaning out the servlet context attributes created
by the old version of the app, which could lead to class cast exception
problems.
Try it, you'll like it :-).
