HTTPs Request Authentication Failing Even After Setting Proxy
Jul 11, 2014
i am trying to access an https request on a server and authenticating it after passing on username and passwork. I have even set up the proxy of the employer to get the request back as a zipped folder.
I always get an error on: " InputStream reader = con.getInputStream();"
Can be a proxy setting issue too but I am not sure why it should be.
Is there a way to create a secure channel in java to connect to https or by any way the below code could be modified to connect it to the server?
Code is as below:
import java.net.*;
import java.net.Proxy.Type;
import java.io.*;
import javax.net.ssl.HttpsURLConnection;
import com.sun.org.apache.xerces.internal.impl.dv.util.Ba se64;
public class DownloadFile
{
For my job I would to develop a Java application which downloads some data from a webpage and then process them.
The problem is that I have to authenticate to a proxy server to connect to the internet. As I browsed on the net, there is a possible way for implementation.
Sometimes it works fine, but usually I get the following exception:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required" at sun.net.www.protocol.http.HttpURLConnection.doTunneling(HttpURLConnection.java:2083) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:183) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1511) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1439) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)
I don't understand what's the problem and why it's not persistent.
I want to send a SOAP xml to HTTPS url using 2 way mutual ssl. I have my certificates installed in my server. I am creating the SSLSocketFactory like this -
void createSSLSocketFactory() {String clientTrustStore = *** Path to trust store file installed on my server. String clientKeyStore = *** Path to key store file installed on my server. //Reading keystore file File keyFile = new File(clientKeyStore);
[Code] ....
So my question is,
1) How can I set the TrustStore and KeyStore in the request.

Now, I've a thread say T which is calls this IPchange() method to use proxy. Now, Thread T creates other threads say T1, T2. When I give URL to crawl for this T1 and T2. T1 and T2 will not call IPchange() method. To crawl URL, T1 and T2 now using my Original IP?
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?
The users of our a enterprise Java based web application must access a third web application through simple HTML links and then navigate in the target application. But for security reasons and constraints the direct exchange between the browers of users and server of the other web application is not allowed. Our web application must retrieve the web page from the other application and must return it to the users's browser. Is there a convenient way to implement this requirement in J2EE ? In this case our web application must play the role of a simple reverse proxy, must request a target JSP page from other application and process it to rewrite the URLs contained in the HTML page, then send the response to user's web browser.
i have this code to connect and login to a HTTPS website Now when i run it i get a 500 code error and if i print out the html of the website it says something went wrong. This is the website [URL]
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
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

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.
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.
I have a problem with several java applications. When I start them Java wants to connect to the certificate authority, to check if the certificate is still valid and not on a blacklist.
The problem is: my whole internet is behind a password protected proxy. If I open my browser i get a windows with username and password. I enter it and internet in the browser works. But for Java it isn't working, because I see no point, where I can enter the password and username for the proxy. I can enter the proxy ip and port in the java settings, but not the password and username. So I get a error screen from java, telling me, that java could not connect. I can disable the check in the java settings, but I don't wont that.
Is there a way to tell java, that java uses my proxy with my password and username? I already googled this problem and found nothing except tutorials for connecting with proxy in the java code. But these applications are not from me, I can't change the code ...
I am making a messenger app using mobile nation, the authentication widget is blocked because im not premium. I have set a text box that says username and password then a login and register button, the register button opens a url to a register page on a xxamp server i have. I made the site with wordpress, so in the mysql database it has wp_users. So when they press the login button id like it to select the username and password entered and run the java script to send that information to the xampp server to authenticate.
i have build an login form with which a user can login to see next form ,login form is working perfectly but whenever a user enters a wrong userid and clicks on login then nothing happens,i want that there a popup will be called and say wrong userid...
However when a user enters correct userid and wrong password then the popup is working but not when the user id itself wrong...
I moved some static html pages I was hosting from apache into tomcat. (no point in running two servers) This works as expected, but I'm having trouble with the authentication part. In apache the authentication was handled by htaccess. I tried various tutorials on the web about configuring basic authentication in tomcat using WEB-INF/web.xml in tomcat, but I'm not sure this approach applies to static html pages. Using basic authentication for static html in tomcat?
I'm building a JavaEE 7 web app and I want to add user authentication. Although I haven't found a complete guide, via the resources I've gathered I think I'm quite close. I can't make it work though. In all honesty I don't understand ALL of the code yet, I'm using it though because it's supposed to work, it's from JavaEE 7 Recipes book.
I've created my database, set up the JDBC realm in GlassFish, added the persistence unit, created the entity classes, the backing bean, the ejb, called the EL expressions...
When I'm supposed to login it throws a "loginBean.username is unreachable" or something. I don't understand why, the inputText's value is supposed to go straight to the backing bean right?
I'm trying to build a SSL mutual authenticating private server. I'm not sure what keystores, truststores, or certificates I need to accomplish this. I made keystores for both programs using:
I am writing a Twitter app, and I am encountering an error whenever I attempt to find the user's name from a screen name. I get the following error:
04-10 21:43:57.402: W/System.err(9326): No authentication challenges found
Which means that somehow, I'm not logged in. However, I am able to post, get the timeline statuses and even get the User of each status. I simply cannot do this:
