Do you have struts.jar in common/lib? It sounds like you might.
(If struts were getting loaded by the web app classloader, then it could see
your WEB-INF/classes without you doing anything to the classpath.)

Subject: reloading classes and struts
Hi all,
I've poked around a bit and have been fairly unsuccesful in finding and
answer to this problem.
I'm running tomcat 4.1.18 on Debian (woody). I'm using struts (1.0) and
for the longest time, everything was great. I could reload my classes
using the manager server reload feature. Then, a few months ago, it
stopped reloading my classes when I'd tell it to. It would say they're
reloaded, but they're really not. I'm not sure exactly when this
started happening, so something must've changed in my system.
My question is- is there anything in my webapp that could cause it to
not actually reload the classes? Static classes? That sort of thing?
One thing I did do was play around with moving to struts 1.1. Could
there be some version of some library thats screwing me up?
Another thing I'm not sure about is where to keep all the libraries I'm
using. Generally, I'm keeping all my .jar files in my WEB-INF/lib
directory. I'm wondering if keeping ALL my jar files there is screwing
something up. I don't have anything in my server/shared/lib directory.
I've listed the entries of my WEB-INF/lib at the bottom of my email.
One other somewhat related problem has to do with struts. If I don't
include my WEB-INF/classes directory in my classpath (set in
setclasspath.sh), then I get:
HTTP Status 500 - No action instance for path
...when accessing a struts action form. An error appears in my
localhost_log to the effect of:
2004-01-22 10:59:44 StandardContext[]: Mapped to servlet 'action' with
servlet path '/admin/MemberInfo.do' and path info 'null' and update=true
2004-01-22 10:59:44 action: Error creating ActionForm instance of class
'com.bzzagent.webapp.beans.MemberBean'
java.lang.ClassNotFoundException: com.myapp.webapp.beans.MemberBean
at java.net.URLClassLoader$1.run(URLClassLoader.java:198)
The weird part is that if I DO include my WEB-INF/classes dir in
setclasspath.sh, struts is happy, but then my classes won't reload.
SO- to sum up:
1. Including myapp/WEB-INF/classes in setclasspath.sh makes struts
happy, but makes it so I can't reload my classes
2. Not including myapp/WEB-INF/classes in setclasspath.sh breaks struts,
but reloading actually appears to work. Auto-detection of classes
changing also appears to work (reload=true in server.xml)
Can anyone explain this behavior?
Thanks for any light someone can shed!
