Servlet container "sendRedirect"

[Ash maker]

Hello,
I have my index.jsp page that contains the include the following:

<jsp: include page ="/ content / foo / bar.html"/>

And a servlet is configured with the following mapping:

<url-pattern> / content/ * </ url-pattern>

So the servlet is called when the induces contained in the index.jsp page When my servlet contains the following code in doGet:

response.getWriter().System.out.println("hello");

Well I get on my page index.jsp. By cons, when I put this:

response.sendRedirect(link);

The variable link url contains a valid property but nothing is returned to include. Is it impossible to use sendRedirect a servlet that is called when a jsp: include?

Hello,

<jsp:include .../>

can include a JSP in a JSP. It can not retrieve a result of a query.

response.sendRedirect(String)

you can run a new query (like the HTTP code 304 with a parameter, the rental value). Use this in your program and try if the program works, if it does well and good else you can post your query.

Hi,
Yes, it is true.

<jsp:include .../>

also allows the inclusion of results from a servlet, if the URL passed as parameter in a target. So what I want to do is put a sendRedirect while processing servlet that, but I think it's impossible ..? If you have a solution round it, then please post.

Hello,
SendRedirect in the servlet called. That is the function is called from the srevlet. And it will look something like this.

<% return; %>

after the include of servlet? This gives:

<jsp:include ..../>
<% return; %>

Hope this helps you.

Hey,
No actually not in the sendRedirect, but rather something like:

request.getRequestDispatcher(path).include(request, response);

except that the path in question is not necessarily, a relative path to a jsp but can be anything and everything eg:

/ components / page.jsp
/ foo / titi.xml
super.html

I hope you are getting my point, what I am trying to explain.

Hello,
The "include" and is the term included the url it flows out of the url-pointed by the RequestDispatcher in the output stream of the appellant jsp (this is also valid for a servlet). We must be careful, because the flow is added to the existing stream, imagine that the appellant JSP is text / html and the URL is pointing to text / xml, what it it will be html? or xml?
