Peter,
Your last comment is a little unclear - do you mean that you request 1 URL
and it gets redirected to another, or that you see some page that you think
shouldn't be in the current web app?
I think more information is in order, specifically, your relevant
configuration information,
What exactly are the errors?
If you are writing a servlet (or some other class that imports something
from the javax.servlet package) you need servlet.jar in your CLASSPATH so
your java compiler knows where to find the class definitions. The Java 2 SDK
does not come with the 'javax.servlet'
Pretty much. See:
http://jakarta.apache.org/tomcat/tomcat-3.3-doc/AJPv13.html
Adding support for SSL, so that isSecure() and geScheme() will function
correctly within the servlet container. The client certificates and cipher
suite will be available to servlets as request attributes.

Although I'm not sure exactly what the problem is, this has happened to me
before when I've replaced some class files or jars that a JSP uses while
Tomcat was running, and then updated the JSP so Tomcat had to recompile it.
A restart of Tomcat fixed the problem.

I'm sure everyone else is gonna tell you this too, but here are some
pointers from just glancing over the code.

Make sure you have WEB-INF/ directories (and web.xml) for those webapps.
Also, try restarting Tomcat. In addition, you can use the manager app to
deploy new webapps.

In 4.0.4 and 4.1.7 (and probably all of 4.x), there is a commented out entry
in server.xml (with explanatory comments right before it). So it looks like

Probably the current working directory, which is whatever directory Tomcat
was started out of (probably bin/, but not necessarily so). You can provide
a full file name in the code, or use your web.xml to set a context parameter
that indicates a base path to do read/write relative to in

I believe that the reason you have so many java threads is due to the way
the jdk/jre is implemented for linux, you'll see basically every thread in

Not sure about the 'reserved' bit, but webapps is the default starting point
for Tomcat to look for directories that conform to the specs. Each
subdirectory should be a complete Context. I'm not sure if the name
'webapps' is actually specified, but that is beside the point. Tomcat will

You can increase the amount of heap space and other good stuff available to
the whole JVM.
AFAIK, Tomcat sets no limit on the amount of memory a servlet consumes.
I'm not so sure you want to do this anyway; besides the security
considerations, you're going to take an extra performance hit where every
request for dynamic content has to go back out over the web to your Tomcat
machine and come back ...
Why can't you just put Tomcat on the Linux box too? or
Tomcat 3.3.x provides the lib/apps directory (see the README file in there)
for Jar files that contains classes to be shared among all webapps.
Sessions are not cross-context. Sessions are specific to the webapp they are
created in for security reasons. Sessions are created via a
