java.lang.NoClassDefFoundError

[Korakaki Stella <sk...@koutcons.gr>]

  I've placed my servlet in the directory : 

$CATALINA_HOME/webapps/ROOT/WEB-INF/classes/Login.class 

and I've written the following at the 
$CATALINA_HOME/webapps/ROOT/WEB-INF/web.xml :

<?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/dtd/web-app_2_3.dtd">

<web-app>
<servlet>
        <servlet-name>
         login
        </servlet-name>
        <servlet-class>
         Login
        </servlet-class>
</servlet>
</web-app> .

Also, I've placed my .jar file at the directory :

$CATALINA_HOME/webapps/ROOT/WEB-INF/lib/jCo.jar .

When I try to reach the address http://localhost/servlet/login it seems
that tomcat can't find my .jar file. I've tried a simple servlet with no
specific dependencies and worked fine.

Please someone tell me what to do in order to have my servlet working...!!!!

I had a similar problem a few days ago when one of my class located 
under common/lib was implementing an interface defined in a jar located 
under WEB-INF/lib, this gives a java.lang.NoClassDefFoundError since the 
common/lib classloader can't access the jar located under WEB-INF/lib to 
check the class signature...

Hope this helps.
