Yes, the Invoker servlet is disabled by default. You need to either: - enable the Invoker servlet (not recommended) OR - explicitly declare your servlet in your web application's web.xml file John -Original Message- From: Ray Tayek [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 26, 2003 9:25 PM To: Tomcat Users List Subject: RE: Manual servlet deployment problems on 4.1.18 i can not get 4.1.18-le to run on win98se and i get at a 404 on linux when i try to put Hello.class manually in .../jakarta-tomcat-4.1.18-LE-jdk14/webapps/ROOT\WEB-INF/classes and using localhost:8080/servlet/Hello (without adding to the web.xml) could the servlet option be turned off by default?

RE: Manual servlet deployment problems on 4.1.18
Tomcat doesn't follow symbolic links by default. You have to enable this in server.xml for each Context where you want to use symbolic links. I'm not saying 100% that that was the problem, just that symlink support is not available out of the box with recent versions of Tomcat.

Manual servlet deployment problems on 4.1.18
Yes, I am a newbie.
I am having some difficulty in getting *any* servlets to deploy on a
Tomcat 4.1.3 installation in my development environment. It is very
likely a simple configuration problem, but I have tried about everything I
can think of to resolve it with no luck.
Environment:
j2sdk1.4.1_01
jakarta-tomcat-4.1.18
Redhat Linux 8.0 (kernel 2.4.18)
All of the example, management and admin servlets are working properly in
the Tomcat instance.
I have tried the simplest possible servlet implementation simple (hello
world). The class definition was ripped of directly from the shipped
examples with only a name change in the class itself (to hopefully
eliminate java class loading problems).
The servlet was deployed as:
{CATALINA_HOME}/webapps/simple
{CATALINA_HOME}/webapps/simple/WEB-INF/web.xml
{CATALINA_HOME}/webapps/simple/WEB-INF/classes/simple.class
The web.xml file contains (less the delimiters):
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app
PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN
http://java.sun.com/j2ee/dtds/web-app_2_3.dtd;
web-app
servlet
servlet-namesimple/servlet-name
servlet-classca.esys.simple/servlet-class
/servlet
servlet-mapping
servlet-namesimple/servlet-name
url-pattern/simple/url-pattern
/servlet-mapping
/web-app
The behaviour that I see is:
1. The servlet appears to deploy when Tomcat starts up (at least the
logs seem to say so). It appears to find the class libraries.
2. When I run the servlet it simply lists the
${CATALINA_HOME}/webapps/simple directory. The logs seem to indicate
that it maps the URI to the default servlet, which lists directories.
It does not run the servlet class that I specify in the web.xml file.
I have tried the following things:
1. I created the following context element in the server.xml file to
explicitly define the context (rather than letting it build an implicit
context).
Context path=/simple docBase=simple debug=1 reloadable=true /
Note that I turned on debugging which elicited the following log entries
in the logs/localhost_log.2003-02-26.txt file.
2003-02-26 10:25:02 StandardContext[/simple]: Mapping contextPath='/simple' with
requestURI='/simple/' and relativeURI='/'
2003-02-26 10:25:02 StandardContext[/simple]: Mapped to servlet 'default' with
servlet path '/' and path info 'null' and update=true
Which seems to confirm the mapping of the URI to the default servlet
rather than the simple servlet.
2. The original simple class was not part of a package and I had it
placed directly under the classes directory. I tried defining it to be
in the ca.esys package and put it under the classes/ca/esys directory, but
that didn't work.
3. I've tried referring to the servlet using the URI's:
localhost:8080/simple
localhost:8080/servlet/simple
The first maps to the default servlet. The second gives a resource
unavailable error - which I would expect.
So ...
I am at a loss. Any ideas for things to try would be very helpful. I've
looked at every example I could find and scanned through the list archive
for similar things, but had no luck.
Thanks ahead for any help that you can provide.
Cheers.

RE: Manual servlet deployment problems on 4.1.18
Howdy,
The servlet was deployed as:
{CATALINA_HOME}/webapps/simple
{CATALINA_HOME}/webapps/simple/WEB-INF/web.xml
{CATALINA_HOME}/webapps/simple/WEB-INF/classes/simple.class
snip
The web.xml file contains (less the delimiters):
servlet
servlet-namesimple/servlet-name
servlet-classca.esys.simple/servlet-class
/servlet
That's a mismatch. If the servlet is in package ca.esys then it should
be under WEB-INF/clases/ca/esys/simple.class.

3. I've tried referring to the servlet using the URI's:
localhost:8080/simple
localhost:8080/servlet/simple
You tried to make it simple, but actually made it complicated.
Your webapp is simple, so you should invoke the servlet by:
localhost:8080/simple/simple
localhost:8080/simple/servlet/simple
Naming all the same tends to confuse users (not sure confuses Tomcat or not). Why not
try:
'test' for the webapp
'Simple' for the servlet
'simple' for the servlet name in web.xml
then you will invoke by
http://localhost:8080/test/servlet/Simple or
http://localhost:8080/test/servlet/simple or
http://localhost:8080/test/simple
Good luck.
