[Java Servlet] Problema coi cookies
Sono alle prime armi con la gestione dei cookies e ho provato a copiare da un libro questo semplice codice:
Codice:
package coreservlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
/** Sets six cookies: three that apply only to the current
* session (regardless of how long that session lasts)
* and three that persist for an hour (regardless of
* whether the browser is restarted).
*/
public class SetCookies extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
for(int i=0; i<3; i++) {
// Default maxAge is -1, indicating cookie
// applies only to current browsing session.
Cookie cookie = new Cookie("Session-Cookie " + i, "Cookie-Value-S" + i);
response.addCookie(cookie);
cookie = new Cookie("Persistent-Cookie " + i, "Cookie-Value-P" + i);
// Cookie is valid for an hour, regardless of whether
// user quits browser, reboots computer, or whatever.
cookie.setMaxAge(3600);
response.addCookie(cookie);
}
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String title = "Setting Cookies";
out.println(ServletUtilities.headWithTitle(title) +
"<BODY BGCOLOR=\"#FDF5E6\">\n" +
"<H1 ALIGN=\"CENTER\">" + title + "</H1>\n" +
"There are six cookies associated with this page.\n" +
"To see them, visit the\n" +
"<A HREF=\"/servlet/coreservlets.ShowCookies\">\n" +
"<CODE>ShowCookies</CODE> servlet</A>.\n" +
"<P>\n" +
"Three of the cookies are associated only with the\n" +
"current session, while three are persistent.\n" +
"Quit the browser, restart, and return to the\n" +
"<CODE>ShowCookies</CODE> servlet to verify that\n" +
"the three long-lived ones persist across sessions.\n" +
"</BODY></HTML>");
}
}
Codice:
type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception java.lang.IllegalArgumentException: Cookie name "Session-Cookie 0" is a reserved token javax.servlet.http.Cookie.<init>(Cookie.java:140) coreservlets.SetCookies.doGet(SetCookies.java:19) javax.servlet.http.HttpServlet.service(HttpServlet.java:689) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.catalina.servlets.InvokerServlet.serveRequest(InvokerServlet.java:419) org.apache.catalina.servlets.InvokerServlet.doGet(InvokerServlet.java:133) javax.servlet.http.HttpServlet.service(HttpServlet.java:689) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) note The full stack trace of the root cause is available in the Apache Tomcat/5.5.15 logs.
