I'm really stumped here and would love some help....
I have a form that is submitting multipart/form-data. (user browses
and selects a file from his/her drive). The problem is in this
servlet it sumbits to. All I want to do is test for the content
length and if greater than a certain size, cause a redirect. For some
odd reason I can not get this to work. It's as if it being
ENCTYPE="multipart/form-data" causes it to act weird. I'm really
stumped here since I could get into the following condition that
should enable me to do a redirect. (Possibly the problem is
multipart/form-data has to be handled before I can do a redirect?).
The following code is below that is not working (and yes, i've
checked a million times- I do have a valid url that it can redirect
too). When the file is too large that submits to this page I end up
with one of those standard IE page not found errors.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import com.oreilly.servlet.multipart.*;
public class ParserUploadServlet extends HttpServlet {
private File dir;
public void init(ServletConfig config) throws ServletException {
super.init(config);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
response.setContentType("text/plain");
try
{
int maxLength = 2*1024*1024; //2MB
if ( request.getContentLength() > maxLength )
{
// !*** this will not redirect for some reason.
response.sendRedirect("http://... the error page.com");
return;
}
else
{
//...rest of code does uploading if size isn't too large
//do rest of code
// ...rest of code does uploading if size isn't too large
}
//!!!this below works fine as long as request.getContentLength() <
maxLength
response.sendRedirect("http://...the confirmation page ok.com");
return;
}
catch (IOException lEx) {
System.out.println("PaserUploadServlet. catchIO Exception : "+lEx);
this.getServletContext().log(lEx, "error reading or saving file");
}
}
}
