How to send a https request using jsf

hi
Can anybody tell a sample how to send a https request using JSF ...
thanks

Prefix the request URI with the https protocol.
The answer is too easy and straightforward that I guess that you mean something else. If you just want to know how to configure an SSL environment for your own webapplication, refer to the Java EE tutorial chapter 28: http://java.sun.com/javaee/5/docs/tutorial/doc/

How to pass a HTTP request from a simple java class

Is it possible to pass an HTTP request from a simple java class.if yes how?

Is it possible to pass an HTTP request from a simple
java class.if yes how?If you're talking about creating a HttpRequest object and passing it to a servlet, that would be a red flag to me that your design is flawed. You shouldn't have to do that - the application server (Tomcat, Weblogic, etc) should be the only thing that has to worry about creating that kind of object and passing it to you.

How to send the transport request from one client to other client?

Hello Friends,
I have generated one transport request in one of the client in Development server.Now as it is customizing request so unless and until i transport it to other client within the same server, Changes will not be visible in other clients.So how to transport this customizing request from one client to other client within the same server.
Thanking you guys in advance.

Hi Jitendra,
Release your Transport Request via SE10, then go to STMS & import the request first to your quality server, then to your production server.
Apologies for the incorrect inputs, please use SCC1 as advised by other forum members
Hope the above clarifies your query.

How to send a http request to a non java appln

I have one legacy web application running which can handle only http request . So I need to connect (using http request) and send my request and get the response, without opening that application in browser.
Any idea
1) How to connect to non - java appln from a java appln ?
2) How to use the Httprequest without displaying the page using browser?

You can try one of three routes:
Open a socket and write the HTTP request and parse the HTTP response yourself
Use java.net.URLConnection
Use Jakarta Common's HttpClient at jakarta.apache.org- Saish

How to submit a HTTP Request from a Java Program

I am working on an web based application where in I need to submit the HttpRequest through a Java Program and not through browser. Moreover my intent is just to submit the HttpRequest. I donot want to wait for the response to come back. I have used the URL Connection class to do the same and I am trying to post this request. The contents of the methods that I am using are as below:-
public void doPost(URL url, String inputXMLString) throws IOException
          //Create URLConnection based on the passed URL
          URLConnection connection = url.openConnection();
          connection.setDoOutput(true);
          connection.setDoInput(false);
          connection.setUseCaches(false);
          connection.setAllowUserInteraction(false);
          connection.setRequestProperty("Content-type", "application/x-www-form-
urlencoded");
          //Get the Connection's output stream and write the request to it.
          PrintWriter out = new PrintWriter(connection.getOutputStream());
          out.print("&ena-request-input=" + URLEncoder.encode(inputXMLString));
          out.flush();
          out.close();
Call to the above method does not invoke the URL I am intending to submit the request at.
Can anybody give me the clue....................................................?

I agree with the advice to launch a new thread to read and ignore the response. I don't think you should have to do it to make it work, but it's worth trying for two reasons:
1) If it turns out it does make it work, well, then either you can leave it that way, or use that as a clue to help figure out how to make it work the way you want.
2) There may be an error message there that will give you an idea why it's not working.
When you say it's not invoking the servlet, what does that mean, and how do you know? Is it just that the final results aren't being seen? Put a bunch of logging statements in the servlet. It could be that it's getting hit, but you're corrupting the string you're building, or sending some extra junk that it can't handle. Spit out a log statement from the start of doPost, to see if it's even getting there. Then log the parameter. Enclose the output in quotes or braces or something to make sure there's not extra junk. I've had XML docs not parse because there was a blank line at the beginning.
If it works in the browser but not from your standalone app, then you need to have the servlet tell what difference it sees in the two cases. Print out headers, other params, everything you can think of.
Re-read the docs for URL, HttpURL, whatever, to make sure you're doing all the right steps in the right order. Make a servlet that just takes a single, simple param=value via POST and see if you can get that to work.

How does Flash send outgoing HTTP request to server?

Hello everyone,
I would like to know how Flash sends outgoing HTTP requests.
I would like to know when from the inside of a Flash SWF file
request for another SWF or FLV file is made; how the Flash sends
this request to server.
Thank you very much and have a great day,

Executing an HTTP Request in ABAP Code

Hi,
I have to write an ABAP program to check VAT numbers before making any VAT declaration. SAP checks the logic of the number, however it does not check if a VAT number is still valid for that company. The European Commission has a website (http://ec.europa.eu/taxation_customs/vies/) where you can check centrally all VAT numbers used in the EU. According to the Commission's web site it should be possible to have an open interface. A SOAP service is available (Its WSDL file can be obtained also on the website).
Does anyone has an idea how this can be done (Current SAP version = SAP ECC 6.0) taken into account there is no XI (or IP) aviable or set up or used.
Thanks,
Jan

Hi,
The examples are calling a browser but that is not what we are looking for. What we are looking for is (via ABAP) to send our http request and receive back the anwser. They (http://ec.europa.eu/taxation_customs/vies/) provide the SOAP message (WSDL : (http://ec.europa.eu/taxation_customs/vies/api/checkVatPort?wsdl). My question is if it is possible witout using XI and yes how? If I understand it correctly is should be possible via ABAP (example program RSWF_TEST_HTTP), but if I create my own program I get the message HTTP-Receive: RC=400 ICM_HTTP_CONNECTION_FAILED. Maybe the ABAP code is correct, but maybe I should change some settings or configure something else.
