Question

I’ve embedded Jetty, and I’m trying to set an initialization parameter.

The main class Main creates a servlet of Cgi which extends CGI.

Within Main, I have the following code:

ServletContextHandler context2 = new ServletContextHandler(ServletContextHandler.SESSIONS);
context2.setContextPath("/cgi");
context2.setResourceBase("./cgi-bin");
context2.setInitParameter("commandPrefix", "perl");
context2.addServlet(new ServletHolder(new Cgi()), "/");
server.setHandler(context2);

Within Cgi, I check to see the parameter:

public void init(ServletConfig servletConfig) throws ServletException {
        System.out.println(servletConfig.getInitParameter("commandPrefix"));
        super.init(servletConfig);
}

Each time, it prints out null for the getInitParameter call. Then when the Cgi does indeed NEED to use this, it doesn’t, because it’s not set. Why could this be happening?

Answer 1

You’re setting the InitParameter on the ServletContextHandler, but you should be setting it on the ServletHolder.

(It’s somewhat confusing, I know)
