Hi, Please don''t laugh :). In many cases, the servers run (on port 80) some important Java applications, and in many cases it''s even Apache''s Jakarta-Tomcat, but without Apache HTTPD (plus connector) cause it always makes trouble, and Tomcat 5.5.x is very fast in delivering static content(saw this trend in a lot of companies). Now how to host RoR application on that server(on port 80 of course)? I would like to put a simple RoR alternative to one of our Java applications, to allow users to compare ''side by side'' :). AFAIK the single chance is the CGIServlet that is comes with Tomcat. http://jakarta.apache.org/tomcat/tomcat-5.5-doc/cgi-howto.html Has anyone did this? Is it stable? Are there any problems that I should be aware of? Thank you very much, Gregor.
