Neven, First of all, I'd like to thank you for all the help. I can say I have learned a great deal through this experience. To clarify, the choice of using tomcat for this was not mine. I am trying to lend a hand to a professor of mine. This specific exercise is in his Unix class. For some reason he thinks tomcat or at least every time he mentioned this exercise to me he made reference to apache tomcat, is meant to be used in the exercise. The exercise is on hosting a web page with perl scripts/cgi. So in his instructions it's clearly using apache on Ubuntu. So he mentioned to me that he was having trouble with the exercise and asked if I maybe I had any idea. I'm not in his class, but I love working in linux and more importantly helping out wherever I can. So I took it upon myself to try to learn the material in this exercise and re-write the instructions, but now I see there was some confusion on his part.But thank you for pointing me in the right direction. * I did not package the cgi script in WAR file, this is most likely the reason it is not working. If you don't mind I would like to work on your JSP code and see if maybe I could write to separate guides for his class, one for the cgi scipt on apache and another for tomcat using JSP. One more thing: "Your ProjectAnalysis.html will have the following form action URL, e.g. <form action="http://localhost:8080/YOURAPP/cgi-bin/project.cgi"; method="post"> </form>?" since it was an example I assume I have to list the whole path for the project .cgi :
<FORM METHOD=POST ACTION=" http://localhost:8080/home/luis/tomcat/apache-tomcat-8.0.0-RC5/webapps/web /WEB-INF/cgi-bin/project.cgi"> -once again thanks for all the help On Tue, Nov 19, 2013 at 11:09 PM, Neven Cvetkovic <neven.cvetko...@gmail.com > wrote: > Felipe, > > As noted in the web.xml comments, in order to make cgi-servlet working, you > need to package cgi scripts with your web application (e.g. yourapp.war): > > "Common Gateway Includes (CGI) processing servlet, which supports execution > of external applications that conform to the CGI spec requirements. > Typically, this servlet is mapped to the URL pattern "/cgi-bin/*", which > means that any CGI applications that are executed must be present within > the web application..." > > > So, if you deployed your webapp as > /home/luis/tomcat/apache-tomcat-8.0.0-RC5/webapps/YOURAPP > > > You will need the following files in your YOURAPP folder: > > WEB-INF/cgi/project.cgi > WEB-INF/cgi/subparseform.lib > ProjectAnalysis.html > > Your ProjectAnalysis.html will have the following form action URL, e.g. > > <form action="http://localhost:8080/YOURAPP/cgi-bin/project.cgi"; > method="post"> > ... > </form> > > > Make sure that both <servlet> and <servlet-mapping> are uncommented. > > Read more details about CGI support here: > http://tomcat.apache.org/tomcat-7.0-doc/cgi-howto.html > > > Now, more important questions for you: > > Why are you using Tomcat and CGI support in Tomcat?
