Hi,
I took a program ( using servlet ) from a book, so I suppose it runs
correctly, I tried it on my PC using sun-java6. Does it have another name?
Other programs, with (swing, applet ...), run correcly.
I searched servlet class in javax, I didn't find it
the error is at the import javax.servlet.*; import javax.servlet.http.*;
here is the example
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class CalculPerimeter extends HttpServlet {
public void doGet( HttpServletRequest req, HttpServletResponse rep)
throws IOException, ServletException {
rep.setContentType("text/html");
PrintWriter pw = rep.getWriter();
pw.println("");
pw.println("");
pw.println(" Just a servlet ");
pw.println("");
pw.println("");
if (req.getParameter("ray") == null) {
pw.print(" ");
pw.println(" need to know the value of the ray!");
}
else {
int tmp=Integer.parseInt(req.getParameter("ray"));
Circle C = new Circle(0, 0, tmp);
double p = C.perimeter();
pw.println("The ray is "+tmp+"perimeter "+ p);
}
pw.println("");
pw.println("");
}
}
The Circle class is of couse defined.
