I have this servlet:
public class SaveImage extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = null;
try {
out = response.getWriter();
out.println("<html>");
...
// I want to include here the content of this jsp:
// /WEB-INF/mybox.jsp
// (also, with the full context of the servlet)
...
out.println("</html>");
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Is there a problem doing it (response already committed?), how can I do this?

You cannot include or forward to a servlet in Apache/JServ or other servlet 2.0 environments; you would have to write a JSP wrapper page instead.
The include directive is used to include a file during the translation phase. This directive tells the container to merge the content of other external files with the current JSP during the translation phase.
To include JSP in another JSP file, we will use <jsp:include /> tag. It has a attribute page which contains name of the JSP file.
request.getRequestDispatcher("/WEB-INF/my.jsp").include(request, response);
But you should not a servlet for outputting html like that. Just use a jsp, with either <jsp:include /> or <%@ include file=".." %>

THANKS ozho , YOU HAVE HELPED ME TO give final shape to 2 year old pending project. Thanks. Actually to redirect the request of tomcat from sun web server 7 to application server, since the jsps are not shown in tomcat directly, technique is to use a passthrough in app.config and let the tomcat handle the requests.
