How to control text in error description in browser?

2003-10-22 Thread Alexandr Molochnikov
Hello,

Under certain conditions my servlet must send an error response to the
browser. I do this by sending ((HttpServletResponse) res).setError(503,
"You goofed"). When this message is displayed in the browser, this is
what gets shown:

In large font on the top of the browser page, the text appears: "HTTP
Status 503 - You goofed".
Below it, in smaller font, the following is displayed:

Type Status report
Message You goofed
Description The requested service (You goofed) is not currently
available.

Apache Tomcat/4.1.27

As you can see, the description field is not very meaningful. I could
not find a method in HttpServletResponse that controls the description.

Does anyone know if (and how) the browser content can be controlled from
the servlet?

Thanks for any help.

PS: No, I don't really say "You goofed" in the message text - it just
saves me typing :-)

Tomcat - Apache connector (JK2) - limited capacity?

2003-10-03 Thread Alexandr Molochnikov
I am facing a weird problem:
 
Our Tomcat is connected to Apache web server via JK2 connector. The
servlet creates a PDF file and sends it to to the browser. If the file
is larger than, say, 100K (haven't measured the breaking point, but it
is below 150K) then the browser page comes empty. Hitting the "Refresh"
button makes the content appear. Smaller files get displayed without
problem.
 
If instead of connecting through Apache we go straight to Tomcat (by
adding port 8080 to the URL), any file of any size can be displayed. So,
it must be the connector that has some default limit on the size of
transmitted data stream that causes this strange effect. But I cannot
find anything in the config files/properties to even remotely hint at
such limit.
 
Has anyone experienced something like this?
 
Here is the environment:
 
OS: Win 2000 Server
Apache 2.0.47
Tomcat 4.1.27
Connector JK 2.0.43
 
Any help will be greatly appreciated.
