CGI script to work on Tomcat
Hi
I am trying to migrate something which was working under apache to tomcat.
I had an html form which takes user input values and pass those values and
executes some cgi scripts. But when I moved html and cgi under tomcat, the
html form is loading properly, but when I click submit, its giving 404
error for the cgi execution.
I have my html files under ROOT and cgi scripts under ROOT/WEB-INF/cgi
Tomcat Version: 7.0.54
And in my html form I have mentioned the cgi location as
<action='./WEB-INF/cgi/read_toggle.cgi'>
I followed the steps mentioned in the below url.
http://www.wellho.net/solutions/java-running-cgi-scripts-in-apache-tomcat.html
I don't see anything in the catalina.out or any other logs. Kindly me help
to fix this issue.

Thanks,
Regards,
Rahul R

Fair enough.

No, nor should it. If you wanted to launch another JVM for stability's
sake (e.g. your "standalone" Java program was buggy as heck and might
run out of memory, etc.) then you certainly wouldn't want the JVM to
outsmart you and do something other than what you've asked.
As an aside, I've recently done some hacking on Runtime.exec in a
litte utility program I've written in Java to get the benefit of the
JDBC API (it's a CLI interactive SQL script runner). I wanted to
launch $EDITOR and let the user edit a query in the query buffer, but
launching something like vi from Java is evidently not possible: Java
doesn't have access to the console... only stdin, stdout, and stderr.
I tried writing pumped-streams to just fake it, but basically nothing
works. :(

Any sane OS, though, would preserve the environment of the process
through those various exec() calls without modification. So going from
Java -> native causes a bit of a stir, but after that, it's fairly
well optimized.

That's pretty clear, given the questions being asked. The page is like
500 words long. It's not like the information is /buried/ in there or
anything. If that page suffers from any problem, it's likely to be
that the information density is too /high/.

mod_perl is the right answer to this problem. This is one of many
cases where fronting Tomcat with a web server is an appropriate thing
to do.

That's just the default, as it comes in the standard Tomcat distribution. See also
https://tomcat.apache.org/tomcat-7.0-doc/cgi-howto.html#Configuration
The OP never actually said what the script was.
Which is a reason why I raised the question.
(perl may not even be installed on that system; but since so far Tomcat did not even
trigger the CGI servlet, we are not yet at the point where this would show up.)
I suppose he could be using a tcl/tk binary re-named to "perl"
> just to have a laugh, but probably not.
He could also be using a stand-alone Java application as a cgi-bin script, for all we know..
Wouldn't that be interesting ? Would the JVM which runs Tomcat actually be smart enough
to notice this, and not load and run another JVM then ?

It is. Tomcat runs the CGI servlet (actually, a Java JVM does that); the CGI servlet sets
up a complete CGI environment (variables and all), then asks the JVM to load and run a
perl interpreter (and the JVM probably asks the underlying OS to do that). The perl
interpreter loads, reads the cgi script, sees the shebang line, and exec's a shell to run
the script. Then the shell reads and runs the script. And the same at each invocation.
If one is looking for a small footprint and/or performance, that's not exactly the way to go.
I was basically raising the question, because it seems to me that, if the OP actually read
the page https://tomcat.apache.org/tomcat-7.0-doc/cgi-howto.html, it nevertheless does not
seem that he read it very carefully. So the fact that perl is the default executable may
have escaped his attention. And since perl will call a shell to run the script if this
actually is a shell script with a proper shebang line, he may never notice all the above.
And then wonder why this appears so resource-intensive.

(Also @David) :
Let's face it : Tomcat is not particularly optimised to run cgi-bin scripts, be they perl
or otherwise. There are better tools to do this, such as an Apache httpd front-end which
the OP seems to have been using so far.
In this particular case, I believe it would probably be better to keep the configuration
maybe a bit more complex, but probably more efficient.
There are cases where simpler is not necessarily better, and I felt that it was worthwhile
pointing this out.

The OP. Look up in the configuration: the "executable" is set to
"perl". I suppose he could be using a tcl/tk binary re-named to "perl"
just to have a laugh, but probably not.

Yeah, but doing CGI in httpd is dead simple. Doing in through Tomcat
is a pain in the neck. IMO any reasonable production application needs
to have at least 2 back-end application servers, so you need a proxy
no matter what. I suppose you could use a hw lb, but those things know
how to route stuff like CGI to some other server, too.

It sounds like the OP is trying to eliminate a layer (HTTPD) in his

Who said that the cgi-bin script was perl ? (not saying that it isn't, but nobody said it
was either).
As it stands, whatever it is, it is being run (at first) by perl. But if perl notice
another interpreter in the shebang line, it will happily cede its turn.
Anyway, it raises the fundamental question of why go though all the trouble to run a
(possibly perl) cgi-bin script within Tomcat ?

https://tomcat.apache.org/tomcat-7.0-doc/cgi-howto.html
Since you have mapped the CGIServlet to /cgi-bin, then you will want
to have your HTML file (located in the webapp root) to reference
"/cgi-bin/read_toggle.cgi" as the action.
Note that the URL reference is mapped from the URL space
(/cgi-bin/read_toggle.cgi) into the webapp's resource space
(WEB-INF/cgi/read_toggle.cgi) which is why the paths don't appear to
match.
Finally, if the Perl script isn't that complicated, you should
consider re-writing it in Java since you are using a Java application
server. It will be much easier to deal with everything that way.

Are you listening to what you are told ?
Did you read https://tomcat.apache.org/tomcat-7.0-doc/cgi-howto.html ?
Did you understand it, and did you do all that is mentioned there ?
To prove it, copy and paste here the content of your conf/web.xml file :

Re: CGI script to work on Tomcat
Posted by Rahul R <ra...@gmail.com>.
More info:
http://localhost:8180/toggle_read.html is html. But after using
<action='./read_toggle.cgi'>
in the html the url loading is http://localhost:8180/read_toggle.cgi and
again its giving 404 error. :(

Thanks Mark for your suggestion. But by privileged, did you mean to add an
entry like below on context.xml?
<Context privileged="true">

Try using the real Tomcat documentation rather than some random Google
result that doesn't even bother to mention which version of Tomcat it
was written for (hint: it wasn't written for Tomcat 7).
Given how you have configured Tomcat, the behaviour you are seeing is
exactly as expected. If you want your script to work with the minimum of
changes you need to:
- Make your web application privileged
- Use <action='./read_toggle.cgi'>
