How to include HTML-Files / Temlplates in Servlets ?

Question

Yep, that's what i need to know.
In JSP there is the include-Command, but with Servlets this Command doesn't work. It's for something else, i think.
I wanna include a header- and a footer-Template within the most of my Servlets.
Thx for Help

You can use the request's dispatcher to include the contents of a template in your response:
request.getRequestDispatcher("header.jsp").include(request, response);
request.getRequestDispatcher("template1.jsp").include(request, response);
if(...)
  request.getRequestDispatcher("template2.jsp").include(request, response);
request.getRequestDispatcher("footer.jsp").include(request, response);This enables your Servlet to dynamically construct the view.
Typically you'd decide which template to forward to in your Servlet and then just use the include directive in your JSP. However, sometimes the decision about what to include can only be resolved by the controller.
There are various other ways of achieving the same result such as passing flags from the Servlet to the top-level JSP template via the request to instruct the JSP to include another template.
Use whichever approach you feel most comfortable with.
Hope this helps.
