error in jsp??? Response has already been committed
Hi,
I am developing some jsp pages, and i get the
following error <br>
java.lang.IllegalStateException: Response has already
been committed
at
allaire.jrun.servlet.JRunResponse.resetContent(../servlet/JRunResponse.java:172)
at
allaire.jrun.servlet.JRunSE.runServlet(../servlet/JRunSE.java:1201)
at
allaire.jrun.servlet.JRunRequestDispatcher.forward(../servlet/JRunRequestDispatcher.java:89)<br>
In my jsp, I have some logic which check if there is
anydata in database or else forwards the request to
other page,
so when i m trying to forward the request i get this
error.
I tried
request.getRequestDispatcher("PL1077Display.jsp").forward(request,
response);
also
response.sendRedirect("PL1077Display.jsp");
and also <jsp:forward >
<br> with same error...
<br> how can i solve it
<br>
Ashish

Re: jsp include question
Posted by Jose Francisco Junior <jj...@zipmail.com>.
If you want to redirect the request you have to do it
before printing any other thing on the page.
Example:
it works:
<redirect code here>
<html>
<head>
...
</head>
...
it does not work:
<html>
<head>
...
</head>
<redirect code here>
...

If that is how your page is programmed - then yes.
In a nutshell - try to ensure your JSP is doing "display" things only.
Or if it needs to perform logic which may invoke errors
(getting/checking data) - try to perform that logic at the very
beginning of the JSP so a minimal amount of info is buffered and
exceptions may be caught and you can effortlessly redirect to an error page.

Re: error in jsp??? Response has already been committed

Hi
I had this problem with tomcat so was verifying with
jrun, and got the same error, i have increades the
buffer size to 128k, so i guess buffer is not filled,
when u say response has send back to client, does this
mean that i have started writing html from jsp, and
half way down i get the error and then i try to
forward the request???
if this is correct i think i will have to modify the
logic

Sneaky sneaky - posting a JRun problem on the tomcat-user list :0
Anyhow - It appears you are trying to forward to another page but you
can't because "you" (actually your servlet engine) have already sent
data back to the client. (Why? I don't know. Maybe because you are using
a JSP that has lots of whitespace which is filling up a buffer?)
Once data is sent back the to client - your can't do any of the following:
- Send redirects
- Forward to another JSP (or servlet)
- Set response headers (Cookies, character encoding ...)
