Re: Tomcat as a service problem
Which version TC you are using? When the memory problem occurs, during the TC up, or running an application?
The cause of the problem is likely on your side, not in TC.

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>
...

Re: error in jsp??? Response has already been committed
Posted by Tim Funk <fu...@joedog.org>.
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
Posted by Ashish Kulkarni <ku...@yahoo.com>.
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 ...)

error in jsp??? Response has already been committed
Posted by Ashish Kulkarni <ku...@yahoo.com>.
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: Tomcat as a service problem
Posted by Jose Francisco Junior <jj...@zipmail.com>.
I am using the Tomcat 4.0.3 and the problem accurs when the
application is runnig. I don´t know why, but the TC is
holding more memory as necessary.
I don´t think the problem is in my side, because the
application works fine when the TC isn't running as
service...
This is a strange problem, I think I should not use TC as a
service until the next release.
Thanks for your atention,
Junior
