When I try to run the servlet the server return to me and exception
I created servlet "HelloWorld" and saved it under webapps>ROOT>utils>WEB-INF>classes.
I created the web.xml file to map it, and I saved it under webapps>ROOT>utils>WEB-INF.
when I click
http://localhost:8080/utils/hello to run servlet, appears:
404 Not Found /utils/hello was not found on this server.
what's the problem?
