java.lang.NoClassDefFoundError

[Mohamed Ganna <mo...@lip6.fr>]

Hi there,

I'm newbie to Tomcat. I'm using Tomcat 4.1.31 under Linux RedHat9.0, and 
I set up all the necessary CLASSPATH and sample servlets are running 
great. I built up a Servlet for user's authentication using freeradius 
0.9.2 and a Java based radius client (jradius-client). The servlet works 
fine with JSWDK + freeradius + jradius-client, but I wanted to encrypt 
the information exchanged between the user's form and the webserver 
using SSL (https based form), that I couldn't do with JSWDK. So, I've 
installed tomcat and tried to use the same servlet (I've made all the 
necessary changes in server.xml, I think so!!!). I've put my ServletForm 
class in $CATALINA_HOME$/webapps/ROOT/WEB-INF/classes and the html form 
in $CATALINA_HOME$/webapps/ROOT/. I access the form using 
https://localhost:8443/ (the form called index.html), but when running 
the servlet I get this error:

I've set up the CLASSPATH for net.sourceforge.jradiusclient.RadiusAttribute. 
Can anyone help figure out what's the pb?

Thank's a lot
