404 handler in Tomcat.
Hello all,
I'm a new user in this mail-list, and I appologize if this question was
already discussed in this list.
I've a Tomcat working with Apache. I've configured Apache to handle 404 error
by /404.jsp :
ErrorDocument 404 /404.jsp
When I try to access non-existed resource ( like /foo.html ), this handler
works excellent. But when I try to access non-exised servlet ( something like
/servlet/foo )... I got a "404 Not found" message from Tomcat. And it looks
dramatically different from Apache's one :))
How should I configure Tomcat to use Apache's error handler?
Sincerely yours,
Felix.

nope, you have to set this up yourself
JkMount /tomcat-example/newserv ajp12

Should "tomcat-auto" do this?
Posted by Joe Emenaker <jo...@emenaker.com>.
When I run Tomcat, it auto-generates an include file for Apache called
"tomcat-auto". It uses a directive called "JkMount" to redirect certain
URL's to Tomcat's non-http interface. For example, my "tomcat-examples"
webapp yields a couple of entries that look like:
JkMount /tomcat-examples/servlet/* ajp12
JkMount /tomcat-examples/*.jsp ajp12
So that anything beginning with "/tomcat-examples/" and ending in ".jsp" or
anything beginning with "/tomcat-examples/servlet" will get redirected to
Tomcat.
Okay.... fine. However, I can define other servlet mappings in the web.xml
file that don't get reflected in tomcat-auto. For example, suppose I made a
servlet called MyNewServlet.class and put it into tomcat-examples. Let's
also suppose that I mapped that to the path "newserv" in my web.xml.
If I do this, I can get to the servlet through Tomcat's HTTP port in one of
two ways:
/tomcat-examples/servlet/MyNewServlet
or
/tomcat-example/newserv
However, going through *Apache*, I can only use the first one, because
tomcat-auto tells Apache to only forward requests to Tomcat if it sees
something ending in *.jsp or something with "servlet" in the path.
So, my question is: shouldn't tomcat-auto also contain JkMount commands for
all servlets that I've mapped to paths in web.xml?

If the actual directory name is "web-inf", then that is your problem. All
pathnames in Tomcat 4.0 are case sensitive, so this must really be
webapps/<mywebapp>/WEB-INF/classes instead.

Is "Quote.class" in the WEB-INF/classes directory? Along with any other

ClassNotFound exceptions with Tomcat/4.0-b2
Posted by S Ramakrishnan <rk...@cisco.com>.
Environment:
Windows2000
Tomcat4.0-b2 standalone
Problem:
I recently upgraded to Tomcat/4.0-b2 from the previous version of
4.0. I find that its not able to locate the servlet class files
under webapps/<mywebapp>/web-inf/classes.
I do not have a security manager installed.
This used to work before I upgraded. Is there a quirk with
TC4.0-b2 about loading classes that I should be aware of?
Also, what should be approach to troubleshoot this failure
to load this class? I have set debug to 4 and am tracking
logs\localhost_log*txt.

Any hints appreciated,
