java - How to configure and where to put a servlet in NetBeans 7.4 accepting parameters from a .jsp page? -

i have worked tomcat don't know how configure , put servlet want accept parameters .jsp page further processing. indicating actual file system path in "action" tag results in "resource not available" or "not found". how should configure servlet including "action" element in .jsp, web.xml , file system? thank you.

a jsp servlet too, , hence forward servlet. (normally other way round, servlet controller, preparing data model request attribute , forwarding jsp view displaying data.)

the servlet defined in web.xml servlet mapping. if use annotations instead mapping similar.

<% request.setattribute("answer", "42"); requestdispatcher rd = request.getrequestdispatcher("/myservlet");    rd.forward(request, response); return; // no output jsp %> 

in above "/myservlet" correspond servlet mapping. forwarding not go browser, leaves servlet forwarded to.

you may alternatively redirect servlet. means going browser calls servlet's url.

response.sendredirect(response.encoderedirecturl(redirect)); 

though looking more circumstantial, used prevent user navigating on posted form, submitting form twice.

if question relates file paths. request.getservletcontext().getrealpath("/css/styles.css") normal way receive file system paths.

in netbeans 1 makes web-project generating .war deploy, , servlets may reside in package like. web-inf/web.xml traditional minded, annotations in servlet class otherwise.
