Class CGI

Implemented Interfaces:
java.io.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.

Method Details

init

public void init()
            throws ServletException
A convenience method which can be overridden so that there's no need to call super.init(config).

Instead of overriding GenericServlet.init(ServletConfig), simply override this method and it will be called by GenericServlet.init(ServletConfig config). The ServletConfig object can still be retrieved via GenericServlet.getServletConfig().

Overrides:
init in interface GenericServlet
Throws:
ServletException - if an exception occurs that interrupts the servlet's normal operation

service

public void service(HttpServletRequest req,
                    HttpServletResponse res)
            throws ServletException,
                   IOException
Receives standard HTTP requests from the public service method and dispatches them to the doXXX methods defined in this class. This method is an HTTP-specific version of the Servlet.service(ServletRequest,ServletResponse) method. There's no need to override this method.
Overrides:
service in interface HttpServlet
Parameters:
req - the HttpServletRequest object that contains the request the client made of the servlet
Throws:
ServletException - if the HTTP request cannot be handled
