Servlet is not running in a diffrent environment

Question

hi friends, until the web environment was there inside $CATLINA_HOME/webapps/ say myapps, every thing was working fine say servlets and jsps were running successfully. but now, when I changed the web environment to a different drive say E:\java\*myapps*, the html and jsp are working fine but servlet only is not running while throwing the error code 404
requested resource /OnlineExam/servlet/myclass is not found.
it sounds surprising as only after changing the drive it is not working.
all the formalities I have done as it is shown from the successful run of html, jsp pages from that environment. and yes!, the required mappings are also done.
here is tomcat 5.5.17 and used url for servlet is http://localhost/myapps/servlet/myclass
any thing yet to do?

I was thinking too that it must be a web.xml issue, sorry i didn't post it before though.
here it is
