Re: how do I enable CGI scripts in Tomcat 6?
Thanks for your reply, Chuck. (1) We do indeed have Context privileged=true. The lower-case C was my typo. I'm not sure why my collaborator decided to set the value here rather in the web app, but we have only one web app running on this machine anyway. (2) We only copied servlets-cgi.renametojar after the steps in http://tomcat.apache.org/tomcat-6.0-doc/cgi-howto.html failed to work. Per your advice, I have now removed it. (3) Here's what we currently have in $CATALINA_BASE/conf/web.xml: servlet servlet-namecgi/servlet-name servlet-classorg.apache.catalina.servlets.CGIServlet/servlet-class init-param param-namedebug/param-name param-value1/param-value /init-param init-param param-namecgiPathPrefix/param-name param-valueWEB-INF/cgi-bin/param-value /init-param load-on-startup5/load-on-startup /servlet servlet-mapping servlet-namecgi/servlet-name url-pattern/cgi-bin/*/url-pattern /servlet-mapping (4) Our web app is in /home/aceorg/aceorg/DEV-2.2/. It has two branches, epoch-plugin/ and courseware/. epoch-plugin/web/WEB-INF/ now contains cgi-bin/, which contains many cgi scripts, including login.cgi. Most of our web app requires a login, so we are unable to point our browser to WEB-INF/cgi-bin/login.cgi directly. However, we do have a public access folder at epoch-plugin/web/public/, which a Web browser can access at http://domain/epoch-plugin/public/, so I made a symlink public/webmo/cgi-bin to point to WEB-INF/cgi-bin. When we point a browser to http://domain/epoch-plugin/public/webmo/cgi-bin/login.cgi, we see the text for WEB-INF/cgi-bin/login.cgi. I have tried various other arrangements and names of the files, to no avail. I also tried putting the above XML in WEB-INF/web.xml instead of $CATALINA_BASE/conf/web.xml, again to no avail. I am ready to try anything you suggest.

Use the real doc. We already had set context privileged=true in Tomcat's context.xml. That's wrong. First, it's Context, not context - case matters. Second, you shouldn't be setting this attribute globally, but rather in just the webapps that need it. We created a WEB-INF/cgi directory in our web app's hierarchy. In $CATALINA_BASE/conf/web.xml, we uncommented the CGI servlet description and servlet matching, and we set the cgiPathPrefix to WEB-INF/cgi/ and the servlet matching pattern to /cgi/*. Please post (via copy and paste) those sections of conf/web.xml so we can see what you actually did. Too often people see what they expect, not what's there. We downloaded servlets-cgi.renametojar from a Tomcat 5 distribution, Bad move. Where in the Tomcat 6 doc does it say to do that? You just broke your Tomcat 6 installation. Tomcat 6 did not come with this file. Because it doesn't need it. Nor, for that matter, can we find a preexisting cgi-bin directory anywhere. Nor should you. That's simply a part of the URL that triggers the CGI servlet, not an actual directory. The script path is specified by the cgiPathPrefix parameter. when we browse to a CGI script in WEB-INF/cgi/ (we actually access it through a symlink in a different, publicly accessible directory) Don't muck with symlinks until you've got it working. No point in introducing extra trouble spots until the basics are functional. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Well, butter my butt and call me a biscuit. Accessing that URL works! I think I can handle it from here. Thanks again. P.S. Sorry for the nomenclature confusion, I'm really a chemist, not a computer programmer.

It has two branches, epoch-plugin/ and courseware/. epoch-plugin/web/WEB-INF/ now contains cgi-bin/, which contains many cgi scripts, including login.cgi. Just to get some nomenclature straight: the term branch is meaningless to the servlet specification. If that term has some internal meaning to you, it does not to us. The directory /home/aceorg/DEV-2.2 is more likely the appBase for a Host defined in Tomcat's conf/server.xml. That means it's the directory used for auto-deployed WAR files and directory-based webapps. The epoch-plugin and courseware branches, as you call them, are really independent webapps. You can tell because each one of them has a separate WEB-INF/web.xml file. Most of our web app requires a login, so we are unable to point our browser to WEB-INF/cgi-bin/login.cgi directly. If you have an executable file in WEB-INF/cgi-bin/login.cgi, then you should be accessing it using this URL: http://host/epoch-plugin/cgi-bin/login.cgi and not http://host/epoch-plugin/WEB-INF/cgi-bin/login.cgi Note that you configured this explicitly in the CGIServlet (see above) using the url-pattern of /cgi-bin/*. There's no WEB-INF in that path. However, we do have a public access folder at epoch-plugin/web/public/, which a Web browser can access at http://domain/epoch-plugin/public/, so I made a symlink public/webmo/cgi-bin to point to WEB-INF/cgi-bin. When we point a browser to http://domain/epoch-plugin/public/webmo/cgi-bin/login.cgi, we see the text for WEB-INF/cgi-bin/login.cgi. Your URL path for the CGIServlet is /cgi-bin/* not /public/webmo/cgi-bin/*, so the CGIServlet isn't being invoked. By adding that symlink, you have allowed the DefaultServlet to serve the raw bytes of the .cgi file, so you see the source code of your perl script (or whatever). Try removing the symlink and hitting this URL: http://host/epoch-plugin/cgi-bin/login.cgi What happens? - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktN6NQACgkQ9CaO5/Lv0PBv7wCgv16UkUZM2edmPV5i9jvFQ6aV o5EAn144Hb9S+ccbTUz7wSfNYkhRnibh =gcZp -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
how do I enable CGI scripts in Tomcat 6?
We have a web application running in Tomcat 6 on Ubuntu, and we want to run CGI scripts in Perl via the browser. The descriptions of the CGI enabling process that we have found on the Web, e.g. http://tomcat.apache.org/tomcat-6.0-doc/cgi-howto.html and http://www.wellho.net/solutions/java-running-cgi-scripts-in-apache-tomcat.html , seem simple enough, but they have not worked for us. We already had set context privileged=true in Tomcat's context.xml. We created a WEB-INF/cgi directory in our web app's hierarchy. In $CATALINA_BASE/conf/web.xml, we uncommented the CGI servlet description and servlet matching, and we set the cgiPathPrefix to WEB-INF/cgi/ and the servlet matching pattern to /cgi/*. (We also tried cgi/* and cgi-bin/* , with no better results.) We downloaded servlets-cgi.renametojar from a Tomcat 5 distribution, copied it into $CATALINA_BASE/lib/, renamed it to servlets-cgi.jar, and put a symlink to it in usr/share/tomcat6/lib/. (Tomcat 6 did not come with this file. Nor, for that matter, can we find a preexisting cgi-bin directory anywhere.) After each step we restarted Tomcat, but when we browse to a CGI script in WEB-INF/cgi/ (we actually access it through a symlink in a different, publicly accessible directory), the browser displays it simply as text instead of running it as a Perl script. The first line of the file says #!/usr/bin/perl, and we have confirmed that we have a working Perl installation at that location. Shortly thereafter, the file tells us we haven't configured our Web server to run CGI scripts. We also tried modifying our web app's WEB-INF/web.xml instead of the $CATALINA_BASE/conf/web.xml, but no joy. I'm sure we're missing something obvious to those in the know, but it's not obvious to us. Any suggestions would be welcome. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
