Hi,
There's probably an older servlet.jar (not servlet-api.jar, which is the
name for Servlet Spec 2.4) around somewhere on the NetBeans runtime
classpath. Or possibly a bigger j2ee.jar containing servlet and other
J2EE APIs. So you're on the right debugging path: multiple instances of
the servlet API jar (but with different names) are the most likely cause
for this error.

Subject: Problem with Manager application
Hello All,
I've recently gotten a new machine and installed
linux Fedora Core 1
j2sdk1.4.2_03
jakarta-tomcat-5.0.19
netbeans3.6
I've played around with netbeans and tomcat in the past and have some
web
apps that I've created and that run fine on an older machine.
On the new machine, when I try to use the manager application that
comes
with tomcat to deploy one of my app, I get this exception.
type Exception report
message
description The server encountered an internal error () that prevented
it
from fulfilling this request.
exception
javax.servlet.ServletException: Servlet execution threw an exception
root cause
java.lang.NoClassDefFoundError: javax/servlet/ServletInputStream
org.apache.catalina.manager.HTMLManagerServlet.doPost(HTMLManagerServ
let.java:142)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
note The full stack trace of the root cause is available in the Apache
Tomcat/5.0.29 logs.
I used netbeans to create the simplest app I could and still got the
same
error.
I looked thru the archives on this mailing list and the closest thing I
found was something that said that java.lang.NoClassDefFoundError is
often
caused by having multiple instances of a jar file on the machine. I
searched around and found that javax/servlet/ServletInputStream is in
tomcat_install_dir/commons/lib/servlet-api.jar, so I searched my
machine
for it and found two instances. One where it should be for tomcat and
another in my home directory where netbeans is installed. This looks ok
to
me but just on a whim I deleted the netbaens install dir and nothing
changed. So now I'm kinda stuck. On my older installation of tomcat
everything works great, anybody have a good idea how to track down my
problem??
Oh yea, when I start tomcat it echos
[EMAIL PROTECTED] root]# /usr/local/jakarta-tomcat-5.0.19/bin/startup.sh
Using CATALINA_BASE: /usr/local/jakarta-tomcat-5.0.19
Using CATALINA_HOME: /usr/local/jakarta-tomcat-5.0.19
Using CATALINA_TMPDIR: /usr/local/jakarta-tomcat-5.0.19/temp
Using JAVA_HOME: /usr/local/j2sdk1.4.2_03
which looks correct to me
Ideas???
Oh yea, Oh yea
it I just place the war file for my app in the tomcat webapps directory
and stop and restart tomcat it deploys and runs fine
TIA
Dave
