I have created a post yesterday regarding this, but someone decided to close it. I have tried solutions from the post, it didn't work. If answer from the post could solve my issues, I won't be asking the same question again. Tried Put servlet class in a package, Set servlet URL in url-pattern, Use domain-relative URL to reference servlet from HTML. The thing is my registration.jsp is almost the same as my login.jsp same for the servlets as well, I dont get why it doesnt work for registration when it works for the login servlet. I also have clean and restarted my server multiples times. Didnt install tomcat into the computer just import it thru zip files into eclipse.
