sendRedirect problem

[he...@sptroth.com]

Hi All

I have to keep a project alive, while my colleague is away... So I don't
know much about tomcat and now there comes a problem where I can't find a
solution. Maybe one of you can help me out here (I hope it is not dumb, at
least I was not able to find any helpful information on the web):

The project is realized with jsp and we are getting a strange
JasperException while executing response.sendRedirect(...)

Here is the code snippet where the exception gets thrown:

if ((request_return.length() > 0)) {
  System.out.println(sessionAddress_ProductTree + "#" + request_return);
  String temp = response.encodeUrl(sessionAddress_ProductTree + "#" +
request_return);
  System.out.println(temp);
  response.sendRedirect(temp);    // <- Here the exception happens

Remarkable is, the html file which the server sends to clients, when this
exception happens is always 16kBytes long (16384 Bytes) and then it stops
abruptly.

I'm running tomcat (stand-alone) version 4.1.18-LE-jdk14 with JDK 1.4 on
Windows 2000

Here is the Output on the server console including the exception:

AcquireDocuments.jsp#305
AcquireDocuments.jsp#305

Re: sendRedirect problem

[Bill Barker <wb...@wilshire.com>]

Is sounds like Tomcat has already started sending the output the the browser
by the time you are trying to do a sendRedirect.  At this point is is too
late to change your mind about what page you want to send.  You have to move
the logic that desides to redirect up before the first 8K of your page is
output.
