Servlet Reload Problem

[Gary Yang <yg...@yahoo.com>]

I am using the latest Tomcat (I checked out from CVS repository this
morning:-)). I have a servlet. When I start tomcat and touch the servlet
class, the reload function works fine. Howerver, after a while, maybe
one hour, if I touch again, the reload function will not work. And then
I delete the class file, but it still can be accessed on my
browser(restarted, without cache).

I've checked loader/AdaptiveClassLoader.java, and added
System.out.println(entry.origin.getPath()+"/"+entry.origin.getName());
after line 316 and recompiled. The problem occured again.
At begining, the servlet's class can be found in ClassCacheEntry,
and then disappeared after a while.

My platform is Redhat 6.1, Blackdown JDK 1.2.2 RC4 with SUNWJIT
Complier. Is that a JIT problem?

I disabled JIT, and it happened again. That means, a servlet may be cached,
but not in
ClassCacheEntry, so can not be reloaded. It can still be accessed even you
delete the class file.
