How are you deploying the servlet? What is the structure of your war file? See http://pdf.moreservlets.com/ for a chapter on a simple servlet and how it is packaged in a war file. This chapter is based on an older version of the servlet spec but should be sufficient to get you going. To deploy to JBoss, copy the war file to the server/default/deploy directory. To redeploy, just copy over the file. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962519#...
