I can't access to my servlet i call with a form. I checked the arborescence, web.xml and the form, but i can't see any problem. I use Eclipse with a "web dynamic project".
There is my arborescence :
My web.xml :
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>Z-ProjetJ2EE</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
<servlet>
<description></description>
<servlet-name>CommandeServlet</servlet-name>
<servlet-class>controleur.CommandeServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>CommandeServlet</servlet-name>
<url-pattern>/urlCommandeServ</url-pattern>
</servlet-mapping>
</web-app>
My form (i tried the complete url, but it didn't works) :
<form action="/urlCommandeServ" method="post">
And my servlet :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String cat = request.getParameter("categorie");
Float prix = Float.parseFloat(request.getParameter("prix"));
response.sendRedirect("CreerCommande?cat=" + cat+"&prix="+prix);
I didn't have any error in eclipse, and the log folder in tomcat is empty. Could you help me ?
EDIT:
There is my error :
I agree for responses about my error on response.sendRedirect, but this is not the real subject of my error :) Even if i erase all of my code on doPost, i have this error, instead of a white page.
You need to include .jsp
when performing the redirect.
response.sendRedirect("CreerCommande.jsp?cat=" + cat+"&prix="+prix);
instead of:
response.sendRedirect("CreerCommande?cat=" + cat+"&prix="+prix);
Also add your contextpath to the url in the form.
<form action="<%=request.getContextPath()%>/urlCommandeServ" method="post">
Change your <form>
html to
<form action="urlCommandeServ" method="post">
When you're posting to /urlCommandeServ
you're asking Tomcat (or your web server) to look for a web application named urlCommandeServ
which isn't there and hence you get a 404.
Why don't you use RequestDispatcher?
RequestDispatcher dispatcher = request.getRequestDispatcher("yourPage.jsp");
if (dispatcher != null){
dispatcher.forward(request, response);
}
See: SO Link
"If this code works in your J2SE it means you need to have a JAR file somewhere containing com.mysql.jdbc.Driver class (so called JDBC driver). This JAR needs to be visible in Tomcat. So, I would suggest to place mysql-jdbc.jar at physical location to /WEB-INF/lib directory of your project."
