Servlet call on WebLogic

I wrote a simple servlet and deployed it in WEB-INF/classes/ ... /, I also updated web.xml file with <servlet-name> and <servlet-mapping>. However when I am trying to call it from my jsp page I am getting "Page cannot be found" and there is nothing in the log file.

My Application server is WebLogic9.1 and after I deployed my servlet I updated my Deployment and activated the changes.

any ideas?
