Class CGI
java.lang.Object
javax.servlet.GenericServlet
javax.servlet.http.HttpServlet
org.mortbay.servlet.CGI
- All Implemented Interfaces:
- Serializable, Servlet, ServletConfig
- public class CGI
- extends HttpServlet
CGI Servlet.
The cgi bin directory can be set with the cgibinResourceBase init
parameter or it will default to the resource base of the context.
The "commandPrefix" init parameter may be used to set a prefix to all
commands passed to exec. This can be used on systems that need assistance
to execute a particular file type. For example on windows this can be set
to "perl" so that perl scripts are executed.
The "Path" init param is passed to the exec environment as PATH.
Note: Must be run unpacked somewhere in the filesystem.
Any initParameter that starts with ENV_ is used to set an environment
variable with the name stripped of the leading ENV_ and using the init
parameter value.
