Servlets :: Return To HTTP From HTTPS

Oct 27, 2011

in my web.xml I declared a resource under the block

<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>

This resource is about a login page.But when I logout or when I visit some pages like Contacts or Home Page, I wouldn't use HTTPS protocol.At the moment, HTTPS remain in the url even if I declared this protocol only for that resource..This is my (little) 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

Servlets :: IE And Firefox Use GET After HTTPS Redirect With TOMCAT 7

Jun 3, 2014

I have a simple application ( only 2 JSPs files and one servlet the main components the whole webapp directory is attached ), I am using security constraint to redirect the user to HTTPS instead of HTTP when he submit from first page to the second page.

The problem is when the user submit the first page I get the error HTTP Status 405 - HTTP method GET is not supported by this URL although I m using only POST.

I have traced the firefox browser using httpfox and the result was the first HTTP request was done using POST correctly but after redirect the browser send GET.

This problem appears with FireFOx and IE but doesnot appear with google chrome.

index.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="myTags" tagdir="/WEB-INF/tags" %>
<html>
<head>
<title>Welcome Page</title>

Servlets :: HTTP 404 Requested Resource Is Unavailable

So I have a screen I click on. The "webPage" comes back as the requested resource unavailable.

What I don't get is that when I run the server locally on my machine it works just fine. But when this is deployed out to server I get the error. The screen comes up but the data doesn't show up. Where should I look to troubleshoot this?

Servlets :: Large File Uploads Through Http Service

Apr 7, 2015

I need to built a file upload service which should be memory effective. I should avoid loading the entire file into memory,Since I may have multiple http request which will pile up the Heap memory. Any effective way to upload a large file(For ex:1GB file) using http Streaming. I need to do the file upload on a single http call. Let's consider a scenario where 1 GB file to be uploaded using 512MB Heap memory. Not Sure If practically I can achieve this or not.

Servlets :: When HTTP Session Object Created In Web Application

Jul 17, 2014

When does HTTP Session object is created in web application. Suppose I have a website. Home page of website is HTTP page which contains details of company and link to Login page.

Consider below mentioned user journey as scenario:

a. user arrives at home page of website
b. user click on Login page
c. user fill in login details on login page and click on Submit
d. user is successfully authenticated and authorized from back end
e. User specific page is shown
f. user click on logout link
g. user is successfully logged out from website
h. user is redirected to home page
i. user closes browser

In the above mentioned user journey,

a. at which step does HTTP session starts (means at which steps does HTTP Session object is created ? )
b. at which step does HTTP session ends ?

In case required, assume tech stack to be Java 7, Servlet 2.5, JSP, Tomcat 7, Apache web server (for static web contents).....

Servlets :: How Is Multipart Http Request Received / Consumed By Server

Sep 9, 2014

I would like to know the details about how a server handles a multipart request. I know that a webserver comprises of a HTTP adapter(which is responsible for receiving http requests and sending http responses) and a container(which is responsible for handling dynamic requests).

So, when a client sends a request, the HTTP adapter receives it. Then transfers the request to the container if the http adapter cannot handle it(jsps, servlets for example).

Suppose, a client sends a multipart request which has an avi file of size upto 100mb. For example, lets assume that the client takes 5 minutes to upload the file.

Lets also assume that my application is only interested in flv files. Is there any way to stop/terminate the multipart request before the file is transferred to the server? So that the client's time will not be wasted?

I think that the HTTP adapter will transfer the request to the container only after receiving the entire request, i.e. the servlet will be called only after the file is transferred to the server from client. Is it right?

If its right then there is no easy way to terminate the multipart request unless the entire file is transferred to the server. Is this right?

Servlets :: HTTP Status 404 Error In Basic Login Form

May 22, 2014

I'm trying to learn java by making a login page using java, servlet, javascript, html and mysql. I can login with username and password, I can get all the information from database in the edit page. However, when I edit and click on "Submit" in EditPage.jsp, it gives HTTP Status 404. Same screen appears when I click on "Sign Up" from first page (NewFile.jsp) and click on "Submit" button after filling up user information.

I am posting all my code here but probably important ones are:

EditPage.jsp, Edit.java, EditDetails.java, UpdateUser.java and for Sign Up SignUpPage.jsp and Registration.java.

Firstly here are my error message and ss from my project explorer:

Here is my code:

LoginServlet.java
package com.amzi.servlets;

Servlets :: HTTP GET Default Method For Web Browsers Contacting Web Servers?

Sep 5, 2014

I am running a test servlet on Tomcat and have implemented different behaviours for the doPost and doGet methods. When I access from the browser, only the doGet method gets called ultimately.

The Firefox developer tools show me a GET request from the browser to my Tomcat instance. Do browsers ever call the POST http method? How could I make this happen?

Servlets :: How To Prevent Particular HTTP Header Attribute From Browser Cache

Feb 26, 2014

I am generating java script tag and javascript code in servlet and displaying it in each jsp page. i include this in every jsp in my application. I am preparing the following javascript content and diplayin each jsp

<script type="text/javascript"> BOOM.addVar (clientId = SOME universal unique ID ) </script>

the clientid will be uniqueid it gets generated every time.

Here my question is, is there any possibility the clientId will be store in browser cache or third party cache server. if yes how to prevent clientId from cache.

I don't want to prevent the whole jsp file from cache. i just want to prevent only that particular field. so that i can use advantages cache and also prevent particular header field to be cached.

Also can we prevent particular http header attribute from cache.

Servlets :: Generating HTTP Requests - Dispatch It To Server And Get Back The Answer

May 4, 2010

Is there any kind of way to generate HTTP request within a servlet, dispatch it to the server and get back the answer delivered to the servlet? Or are the servlets meant only to respond to passed requests, not generate them?

Servlets :: Login Form - All Attributes Are Null And HTTP Status 404 Error In Some Cases

May 20, 2014

I'm a new Java user and I'm trying to code a simple login page. In first page (NewFile.jsp) users should enter their username and password and should click on "login", or click on "sign up".

1.) If user enters his username and password correctly, a login page (LoginPage.jsp) appears and says "welcome null" but it should show the name of that user instead of null.

2.) In that login page there is an edit button to edit profile information. When I clicked on it, every information is "null" and when I edit them and click on "Submit" button;

HTTP Status 404 -
type Status report
message
description The requested resource () is not available.
GlassFish Server Open Source Edition 3.1.2

that message appears.

3.) If I click on "Sign Up" button at the beginning, a registration jsp (SignUpPage.jsp) appears. After filling up text boxes and clicking on "Submit", same Status 404 screen appears.

I created a mysql database called "loginpage" using xampp. In that database there is a table called "users" and it has un, pass, name, surname, email and degree attributes.

Here is a screenshot of my project explorer:

Here is my code:

1. NewFile.jsp

<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.util.*"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

Servlets :: GET HTTP Request Contain A Request Body?

Feb 25, 2014

I have the following questions:

1. Does a GET HTTP request contain a request body? If yes what is contained in it? Are the request headers also part of the request body?
2. Is it possible to send a byte array as part of the GET request in its body?
3. Is there a size limitation on the data that can be sent via a GET request?

Method Must Return Int Type - If Given Integer Is Strong Return A / If Not Return B

Sep 7, 2014

I want to use a method, which takes for example an int and also returns an integer. For example, if the the given integer is strong return a, if it is notstrong return b. How would you write that in a Code?

I want to use that in a more general way. I want to give a method mlong the value X of the type date and let it return an int. Type date consists of 3 int, one of them is the int month.

mlong should return an int depending on the X.moth. at the moment my code looks like this:

// File1:
public class date {
public int day;
public int month;
public int year;
}

// File 2:
public class monthlength {
public int mlong(date X) {
int t;
t = X.month;
if (t == 1 || t == 3 || t == 5 || t == 7 || t == 8 || t == 10 || t == 12)
{ return 31; }
if(t == 4 || t == 6 || t == 9 || t == 11)
{return 30;}
}

Networking :: URL Connection Error On HTTPs

Feb 16, 2013

I have noticed an error, that makes sometimes troubles, when downloading jars from https addresses, when there are many jars to download..

Best example is by opening Javas on Java version checker. [URL] ....

I get also following log...

network: Connecting https://www.java.com/jsp_utils/jreverification.jar with proxy=DIRECT
network: Connecting http://www.java.com:443/ with proxy=DIRECT
network: Connecting https://www.java.com/jsp_utils/jreverification.jar with cookie "JSESSIONID=22ABBA2BE9B5789629C276AC35BDF969; s_cc=true;

Even if the address is https, java try to access via http protocol on port 443, and that leads sometimes to problems..

I have noticed this, when I have used URLConnection(HttpURLConnection) for my self, as soon Java sends http link on https address, the jar gets sometimes not loaded, and i get error about missing class that get called..

On http addres it is not so bad, since same protocol is used, but evidently, that is evil for https..

As you see, that happens already when loading Jar by Applet Starter and at all, it happens each time on any URLConnection

Securing Client Server HTTPs Connection

Mar 1, 2014

I have a https connection from Client to Server and a malware in client. The malware modifies the message and compromises its integrity. I am using a proxy to check the Integrity of the message after the malware has changed the message and before sending it over the internet to the server.

Now, How can I check the Integrity of the message (Sure that it has not been modified by any Man in the Middle) for the second half of my communication channel(Which is from Client to the Server over the internet).

I see few conventional approaches of CRC or Checksum will work. But I am looking for some non traditional or upcoming approaches.

Ideally SSL Data shouldn't be able to be decrypted by any MIM. But my assumption is that any Protocol is subjected to attack and compromised in real world and few recent studies are proving that https is breakable. Thus, I am trying to perform a What if analysis? On the client side, lets say malware is not more powerful than just modifies the transaction amount and destination account number in a typical online Baking transaction.
