here is the the servlet cod

Answer 1

As per the specs , it can take any valid URI

This attribute specifies a form processing agent. User agent behavior for a value other than an HTTP URI is undefined.

Can i give the servlet class in the form action ?

Yes if the servlet class name resolves to a valid URL mapped in the web.xml or else you will encounter a 404 .

Let us consider your JSP is at the root of the application, then

<FORM action="someServletName" method="post">

Now this will be resolved as protocol://servername:port/context/someServletName .Now somewhere you should have a mapping for /someServletName , either in web.xml or through annotation to a Servlet or JSP.

<servlet>
     <servlet-name>someServletName</servlet-name>
     <servlet-path>packageName.servletName</servlet-path>
</servlet>
<servlet-mapping>
     <servlet-name>someServletName</servlet-name>
     <url-pattern>/someServletName</url-pattern>
</servlet-mapping>
