Problem with jar files in Tomcat 5.X

[Devireddy, Nagendra Reddy (STSD)]

Hi ,

I have installed Tomcat 5.0 and trying to access the sample servlet
examples.
My directory structure is like this

<tomcat installation dir>/webapps/sample is the directory where I have
my files

<tomact installation dir>/webapps/sample/index.html
<tomact installation dir>/webapps/sample/WEB-INF/web.xml
<tomact installation dir>/webapps/sample/WEB-INF/lib/sample.jar

When I try accessing index.html .. Its throwing classdefinationNotFound
error .. But that class exists in the sample.jar 

But When I unjarred and kept all the classes under 

<tomact installation dir>/webapps/sample/WEB-INF/classes/*.class

Then its working perfectly fine ..

Can some one please help me in resolving this issue ..

Thanks in advance,
Nagendra
