Hello all,
I've been knocking my head against this for a few days now. I have a
GWT webapp (running on Ubuntu Lucid Lynx) which acts as a kind of
dashboard for my application. The dashboard has a number of tabs, one
of which displays my bugzilla installation. The bugzilla home page is
contained within a Frame. The Frame is initialised as follows:
// bugzilla tab
// Apache must be running for this to be served
com.google.gwt.user.client.ui.Frame bugFrame = new Frame("http://
localhost/bugzilla");
bugFrame.setStyleName("frame");
DOM.setElementPropertyInt(bugFrame.getElement(), "frameBorder", 0);//
remove frame border
DecoratedTabPanel tabPanel = new DecoratedTabPanel();
tabPanel.add(bugFrame, "Bugzilla")
The bugzilla installation runs on Apache and MySQL, and works fine
when I access it via http://localhost/bugzilla. I can view, create and
edit bugs, all perfectly fine. Please note that the bugzilla index
page is index.cgi.
However, when the GWT webapp runs, no output is displayed for the
bugzilla tab. I have tried using both GWT development mode and a
separate Jetty server on port 8080 to see if that makes a difference,
but the results are identical. The Apache access.log file appears to
indicate that the page is successfully fetched, but nothing happens:

If I change the bugzilla URL in the GWT code above to fetch some page
which is not a cgi file (e.g. http://localhost/bugzilla/README), it is
rendered fine. It seems therefore that I have some configuration
problem which prevents GWT from displaying the output of a cgi file.
My apache2.conf file reads as follows (the bugzilla cgi config section
is at the bottom).
Does anyone have any pointers for me, please? Thank you.

============
#
# Based upon the NCSA server configuration files originally by Rob
McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are
unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server
process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default'
server,
# which responds to requests that aren't handled by a virtual
host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent
to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for
many
# of the server's control files begin with "/" (or "drive:/" for
Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/
apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#
### Section 1: Global Environment
#
# The directives in this section affect the overall operation of
Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation
(available
# at <URL:http://httpd.apache.org/docs-2.1/mod/
mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/apache2"
#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.

LockFile /var/lock/apache2/accept.lock

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited
amount.
# We recommend you leave this number high, for maximum performance.

MaxKeepAliveRequests 100

# KeepAliveTimeout: Number of seconds to wait for the next request
from the
# same client on the same connection.
