OK, this problem is caused because I forgot to place the .jar file into tomcats common/lib directory.
Tomcat 4.1.18 seems to have its own classpath and therefore you end up using replicated files

I thought I had fixed all my problems until this one arose.
Basically I make a call to the method:
Class.forname() which allows dynamic loading of java classes at runtime.
But catalina is reporting errors....
Does anybody know a fix for this?

Reply. It doesnt seem to matter about where they are!.Definately works with tomcat 3.2.1 but I did change it anyway!
The problem I had which leads to a resource load up failure was actually in the server.xml file.
I had mistyped a <context> so the path was wrong.
Maybe we should put together a list of common errors so people can quickly pinpoint where they have gone wrong.

Im having problems in migration from tomcat 3.2.1 to tomcat 4.1.18.
I was initially having problems setting the context in server.xml and parser problems in web.xml but these seem to have disappeared.
I can run http://localhost:8080 and /examples
but not my context path /intranettv
My new problem is that when i try to view my servlet, it is returning a 404 error for the page
http:/localhost:8080/intranettv
It doesnt seem to be initialising the servlet.
Basically my server.xml points to new context here:
D:\intranettv\admin\public_site\ alias internettv
Here is my web.xml

Does anybody now what is happening.
(This is not a getout clause-but i compiled the java source with java 1.2 but tomcat is running under 1.4) Will this cause any errors? Some of somebodys java code doesnt compile with java 1.4 so i thought this would be a quick way out?
FROM THE CATALINA LOG FILE IM GETTING AN ERROR.
DOES ANYBODY KNOW WHATS CAUSING THIS ERROR LOG.

basically all i want to know is what I have to add to the server.xml so I can use my own path to my classes. and also want to know what is the minimum I need to put in the web.xml for tomcat 4.1.18. What is the structure for these web.xml. I dont be able to find any great examples of what should be included and what is the minimum to get away with.
The web.xml works fine with tomcat 3.2.1 but I havent modified it for tomcat 4.1.18. Therefore how do you modify tomcat 3.2.1 web.xml to change to tomcat 4.1.18??
Is adding the context for server.xml, in the way ive previously noted, correct for tomcat 4.1.18???

Hi, Ive been trying to get a servlet working on tomcat 4.1.18. (basically trying desperatley to upgrade from 3.2.1 to see if any perfomrnace gain)
My problem is that tomcat will now startup itself and display jsp pages and htm pages in the examples folder.
I need to add another folder.
In tomcat 3.2.1, I edited the server.xml to include an additional context like:
<!--derrick added this line
<Context
path="/intranettv"
docBase="D:\intranettv\admin\public_site"
debug="0"
reloadable="true"
crossContext="false">
</Context>-->
Then all i had to do was go to localhost:8888/intranettv/+class¶ms
When i try to add this context to tomcat 4.1.18 server.xml it goes a bit mental and complains about parser errors in web.xml
Do i also have to change web.xml somewhere else??
What do I have to do from this point to get the tomcat to recognise where the servlet is stored and where to put a pointer to the initial servlet class!!
Help please!
ps the old Web.inf for tomcat 3.2.1 looked like this. Does this need to be changed for tomcat 4.1.18
