tomcat connector through cgi-bin?
Hi, Has anyone here ever had to use a cgi-bin directory to try and
connect to tomcat? ie, some script that when run under cgi-bin, connects
and forwards the info to tomcat? I cant find much on it, but it would be
really handy. (Have a web server that i cant install a connector in!).
Best Regards,
Jacob

Why not post it to the list. Then it will be in the archives and we can
all point to it when someone asks for this kind of thing.

I agree, that is the best option, and that is the most logical thing!
However there are external issues which prevent this from happening
right now *sigh*! I would like to work in a place where the
cheapest/best thing is the thing that can be done!
Anyway, In case anyone is interested, I have now written a perl script
which does exactly that. So if anyone needs a "perl tomcat connector"
send me an email. (:
Best Regards,
Jacob

Sorry to be so negative, but I'd suggest getting a new webserver then:
1) hosting is cheap, 2) you can configure the server to do what you
really need it to do.
There's little point in trying to force a cgi environment to forward
requests into Tomcat, if your server doesn't support it.
It's a false economy if you spend more than the equivalent hosting cost
in your time trying to resolve this - not a really a good idea at all.

Hmm. And the system administrator cannot be convinced to add
configuration directives for your virtual host or anything like that? Hmm...
Do you have access to PHP? I think you might be able to get away with a
small PHP script that uses an HTTP include. I think that would be easier
than writing a Perl-based (or worse, C-based) CGI program.

Can you use that one? Or will it not work for Tomcat for some reason?
Using PHP, you should be able to use the HttpMessage
(http://php.net/manual/en/http.HttpRequest.php) object and stuff it with
cookies, headers, parameters, and the request body from the incoming
request. Make the request and stream the result.
Note that I've never tried this and so I could be completely wrong.

Its a system where we have no permission on any files except user home
directories and the cgi-bin directory. So we can run tomcat as a
non-unprivileged user on a high port, but we need the ability to allow
files to be served through the apache web server on port 80.
So it has to be something we can install in the cgi-bin directory. In
the past we have had a perl script to simply make a connection to an app
server and pass the data through.
There is a very large set of Perl scripts (that have grown to the point
where its inefficient and unmanageable) that I would like to start
rationalizing/organizing into a simpler Java app.
Best Regards,
Jacob

Do you mean that you can't install something like mod_jk? Or, that you
can't use a Tomcat <connector> with a port number?
You might be able to use proxying (possibly?) already available in your
web server to simply proxy requests to an HTTP connector running in
Tomcat. I think this would be cleaner than a cgi-bin->Tomcat hack.
What is your environment? Perhaps we can come up with a better solution.
