JSP redirect servlets

Question

I'm new to jsp and servlets.I'm using jwsdp .
my index.jsp will call a servlet and servlet will redirect to
jsp.both jsp files are in the root
(\jwsdp-1_0\webapps\ROOT)
1) where should i save the servlet ??
2) How do i call index.jsp action to servlert??
is this correct?
action="servlet\MyServlet";
3) How do i come to my second jsp
response.sendRedirect("/Mysecond.jsp");

Answer 1

I don't use jwsdp so I can't help with the first question.
If MyServlet is your servlet class name then 2 is correct. Normally you would declare your servlet and make a URL mapping in your web.xml file.
eg:
<web-app>
<servlet>
<servlet-name>ProcessOrdersServlet</servlet-name>
<servlet-class>com.company.ProcessOrdersServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ProcessOrdersServlet</servlet-name>
<url-pattern>/ProcessOrders</url-pattern>
</servlet-mapping>
</web-app>
then in your jsp <form action="ProcessOrders">
For question 3.
If you have finished processing in your servlet and want to send the next display page to the browser use:
request.getRequestDispatcher( "nextpage.jsp" ).forward( request, response );
This will also preserve any parameters and attributes in the request object.
