Listen for HTTP Post in Flex

Hello,
I just have a simple question. In my Flex program, I am trying to find a way to listen for an incoming HTTP POST message - something with functionality similar to that of the HttpListener class in C#. I have not been able to find anything at all to help with this though, would anyone know of something like this?
Thanks.

My Flex program subscribes to changes that occur in a program on remote server. The change notifications are sent back to my client in the form of an HTTP Post message. The Flex program needs to be able to detect when these Posts are received.

Http_utl.text_write for http 'POST" does not work

i have a proc that uses utl_http code I have seen all over on web sites for 'POST'ing to a REST web service ..... i use utl_http.write_text to write data to the request body but no data gets written ...... below are the code segments I use
url entered directly into browser that **works fine**: http://www.media.com/admintool/Services.aspx?par_string=[{ "PAR_Transaction_Id" : 5566338, "MRI_Title_Name" : "4 Wheel & Off Road"}]
calling routine:
declare
l_url varchar2 (300) := 'http://www.media.com/admintool/Services.aspx';
l_data clob;
l_query varchar2(32767);
begin
dbms_output.enable(3000000);
l_data := '[{
"PAR_Transaction_Id" : 5566338,
"MRI_Title_Name" : "4 Wheel & Off Road"}]
http_util_pkg.http_post(
p_url_in => l_url, p_data_in => l_data);
end;
called routine segment:
l_http_req := utl_http.begin_request (p_url_in, 'POST');
-- Set the HTTP request headers
utl_http.set_header(l_http_req, 'User-Agent', 'Mozilla/4.0');
utl_http.set_header(l_http_req, 'content-type', p_data_type);
utl_http.set_header(l_http_req, 'content-length', v_length);
-- Write the data to the body of the HTTP request
utl_http.write_text(l_http_req, 'par_string=');
while v_index <= v_length
loop
utl_http.write_text(l_http_req, substr(p_data_in, v_index, 4000));
dbms_output.put_line ('data = ' || substr(p_data_in, v_index, 4000));
v_index := v_index + 4000;
end loop;
results .... you can see below that the header content length is non-zero but the response header says there is no content, so something is haywire with the write_text method
url = http://www.media.com/admintool/Services.aspx
length in data = 1271
http package; url = http://www.media.com/admintool/Services.aspx
after set authentication
after write headers
data = [{
"PAR_Transaction_Id" : 5566338,
"MRI_Title_Name" : "4 Wheel & Off Road"}]
after write text
status code: 200
reason phrase: OK

can you help me figure out what is wrong with the utl_http.write_text method ???
thank you

Please do not resurrect old threads - rather ask your question in a new thread. If need be, add a URL in your new thread posting that refers to the old thread. Also add as much relevant details as possible. Your Oracle version (all 4 digits). Your o/s. If possible, sample code and data that can be used as a test case. Complete error details. And what the intent of the code is (i.e. what the actual problem is that you're trying to solve).
As for HTTP post - works just fine as far as I've used it.

Example-WSDL for http-POST binding

Hi all,
i'm looking for an example-WSDL of a http-POST binded service. I was searching in the ~\OraBPELPM_1\integration\orabpel\samples\tutorials\702.Bindings\HTTPBinding directory, but its the example is of a http-get binded service.
I need to know, how the message-definitions for the input have to look like (in the message-section and in the operation-section) when using an XML-input message.
thanks in advance
Albrecht

Gee! i didn't know there are some more samples! :o)
Thanks Clemens, i will test it.

HTTP authentication key for hand shake at receiver side for HTTP POST

Hi All,
HTTP post receiver system is expecting an authentication key to be send by PI HTTP_AAE adapter while posting XML message to them.
The receiver system has a utility program in JAVA to validate this key. Has anyone done this kind of scenario in PI 7.31/7.4
How does this simple authentication mechanism works? If this doesn't work, we have to rely on just uname/pwd but that is not really recommended for our landscape because of security concerns. So the key is the only better option as of now. Please help!!
thx
mike
Attached some import packages used in the java util program in the receiver system. for validating the authentication key send by PI
import java.security.MessageDigest;
import java.util.Calendar;
import java.security.NoSuchAlgorithmException;
import java.io.UnsupportedEncodingException;
import java.io.IOException;
import sun.misc.BASE64Encoder;
import sun.misc.BASE64Decoder;
I am not pasting the java program utility here due to proprietary reasons. thx for understanding

Hi Michael
You can construct the target URL to include the query parameter/value using Dynamic Configuration in Message Mapping.
This previously worked on the ABAP HTTP adapter, but from the thread below it seems it is not supported on the HTTP_AAE. Not sure what version you are on, and if SAP has provided support for this in the latest SPs.
HTTP_AAE Adapater - using of dynamic url parame... | SCN
If HTTP_AAE approach can't work for you, you can use the SOAP adapter - check ASMA and "Do not use SOAP envelope"
Here is a snippet of the code you can use in a UDF for your message mapping
   //write your code here
DynamicConfiguration conf = (DynamicConfiguration)container
    .getTransformationParameters()
    .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP", "TServerLocation");
String url = "http://local.yahooapis.com/MapsService/V1/mapImage?appid=" + appid + "--&street=" + street + "&city=" + city + "&zip=" + zip;
conf.put(key, url);
return appid;

How to make the App Server Listen for HTTPS

I have a web application that needs to be accesible over an HTTPS connection, not HTTP.
When I deploy an application with Java Studio Creator to the App Server it is automatically set to an HTTP URL. How do I setup HTTPS ?
Thank you in advance,
Joe Paladin

Looks like I should have thanked myself in advance....
Turns out its pretty easy. Open the admin console, go to configuration, add and HTTP listener, check the security check box, and fill out the other mandatory fields like the port. Standard SSL port is 443.
Save changes, and restart the App Server. Any deployed apps should be reachable via https://localhost:443/myWebApp
This approach uses a default certificate that comes with the app server. Here is a link if you want to create a certificate :

Java Mapping for HTTP Post

Hi
Im following this blog http://scn.sap.com/community/pi-and-soa-middleware/blog/2014/09/12/html-form-upload-using-http-plain-adapter-with-java-mapping but I have encountered an issue which I cannot solve.
My issue is, in addition to the required output, I am also getting unwanted XML added, which originates from the Message Type in the source Service Interface,
i.e.
Content-Type: multipart/form-data; boundary=--ejjeeffe1
--ejjeeffe1
Content-Disposition: form-data; name="event"
Content-Type: text/plain
Import File
--ejjeeffe1
Content-Disposition: form-data; name="Filename"
Content-Type: text/plain
TestFile.zip
--ejjeeffe1
Content-Disposition: form-data; name="content";filename="TestFile.zip"
Content-Type: application/zip
Content-Transfer-Encoding: binary
<?xml version="1.0" encoding="UTF-8"?><__EmptyDoc></__EmptyDoc>
--ejjeeffe1
Any suggestions much appreciated.
Regards
Steve

Hi Stephen
The xml must be getting added in the below part of the code. It is coming from arg[0]
You can put a check and get it removed.
while ((len = arg0.read(buffer)) != -1) {
arg1.write(buffer, 0, len);

Beginner question: support to HTTP POST om Oracle AS

Hi!
I don't know if this is a suitable forum but since i use JDeveloper and Oracle BPEL I'll try my luck here :).
I have a Java web application built in JDeveloper and a couple of BPEL processes.
In these processes I use Java embedding (a piece of Java code) that opens a connection to a given URL and post a XML message to this URL. I didn't have much problems creating these processes.
Now I have to provide a support to HTTP POST on my side. Since web application and services development are quite new to me I hope someone can point me the right way to do this. The requirements I have are: I can have a single URL to which the http POSTs will be issued.
If I understand correctly I cant use a web service since I have to enable different types of XML posts. What are my options? Can I create some kind of listener for http POSTs? Can I create a jspx that will 'wait' for http posts and than call some of mine BPEL processes? Is there a way to create a BPEL process that 'waits' for http POSTs? Are there other options.
I'd really appreciate any pointers on this.
Regards,
BB.

Frank,
I've tried creating a Servlet listener that implements HttpSessionListener interface. Now I have two methods, sessionCreated and sessionDestroyed but I don't know where to go next. I can't find any documentation on this issue yet.
Should I create a jspx page with form node that has method attribute set to POST or maybe I don't even need a web page? I already have a login page that has a form with method set to POSt, will this pose any kind of troubles for me?
I apologize for any stupid questions but as I said I have no experience in doing this and las couple of days I'm searching and reading different documentation on this topic so any more pointers would be appreciated.

Handling incoming "HTTP Post"

I'm a bit confused here...
I've Flex 3/ActionScript as front-end with Java back-end (with BlazeDS in between);
I need to receive an incoming "HTTP Post" sent by external server (paypal IPN) to a specific URL I need to provide - notifying on specific event, and do some action in response to that event.
> How do I implement such listener to an incoming HTTP Post in Flex?
> What kind of setup is needed to link that listener to the relevant URL?

Hello,
I have the same problem. Could anyone manage this situation?
Thanks,

How to set mouse listener for title bar of JFrame ?

Hi, all
How to we can set mouse listener for title bar of JFrame ?
Please help

Again, why did you not state this in your original
question? Do we have to ask you every time what your
actual requirement is?
As I said in your last posting, if you don't give us
the reuqirement in you question we can't help you.
Sometimes your solution may be on the right track
sometimes it isn't. We waste time guessing what your
are trying to do if you don't give us the
requirement.
I gave you the answer in your other posting on this
topic. The AWTEventListener can listen to events
other than MouseEvents.
The Swing tutorial has a list of most of the events.
Pick the events you want to listen for:
http://java.sun.com/docs/books/tutorial/uiswing/events
/handling.htmlthe first, i am sory because my requirement not clear so that it wasted everybody time.
The second, thank for your answer
The third, AWTEvenListener do not support listener event on title bar
but ComponentListener can know when we can change frame position.
please see below that ComponentListener can handle action:
public void componentHidden(ComponentEvent e) {
        displayMessage(e.getComponent().getClass().getName() + " --- Hidden");
    public void componentMoved(ComponentEvent e) {
        displayMessage(e.getComponent().getClass().getName() + " --- Moved");
    public void componentResized(ComponentEvent e) {
        displayMessage(e.getComponent().getClass().getName() + " --- Resized ");
    public void componentShown(ComponentEvent e) {
        displayMessage(e.getComponent().getClass().getName() + " --- Shown");
    }Thanks for all supported your knowledge, you are great !

CSS Sorry Server for HTTPS

I just deployed a couple 11050's the other day so my experience is limited, but I'd guess your problem is that, when using the Primary Sorry Server, you end up with clients sending HTTPS requests to an HTTP port. Having HTTPS requests redirected to HTTP ports is one thing because the client then makes an HTTP request to that port, but the way you have it above, it appears to me that the client will be talking HTTPS to port 81 on the Sorry Server, which is listening for HTTP.

Javier,
I would suggest you to start with something basic and than add complexity.
Create a very simple content rule with just an ip address. no port. no protocol.
Then add one or more servers.
Activate.
Give it a try like this.
Does it work ?
If yes, define 'protocol tcp' and 'port 80'.
Does it work ?
If yes, configure 'url "/*"'
does it work ?
If yes, configure 'advanced-balance arrowpointcookie'
This config is explained at
http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_tech_note09186a0080094398.shtml
It it does not work, tell us what is not working.
Is it the stickyness that does not work or you can't even connect to the vip address ?
Also collect a sniffer trace on client and server.
Thanks,
Gilles.

Connect by HTTP-Post

Hi,
am i correct if i think that it is not possible to connect to rwservlet via http-post, only http-get.
And that is the reason i get REP-56048 when i try it?
Thanks.
Regards
Chris

Hi,
thanks for this suggestion. It put my on the right way, because i examined the http-request, sended by the form with paramform=yes.
In my case a report is called with paramters which executes a sql-query on a database.
For this a key is configured in cgicmd, that holds the DB-connection data and takes the other parameters from the url-parameters.
Calling a report per HTTP-Post that doesnt need a database connection was easy, since it didnt need to use the cgicmd-key.
But calling the cgicmd-key didnt work.
The report enginge crashed:
[2012/6/12 11:1:58:807] Exception 50125 (org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 208 completed: Maybe
at com.sun.corba.se.internal.iiop.IIOPConnection.purge_calls(IIOPConnection.java:438)
at com.sun.corba.se.internal.iiop.ReaderThread.run(ReaderThread.java:70)
): Interner Fehler org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 208 completed: Maybe
[2012/6/12 11:1:58:807] Info 56029 (EngineManager:shutdownEngine): Shutting down engine rwEng-0
It turns out that for HTTP-Post not the same URL as for HTTP-GET can be used.
In contrary to GET in case of POST the cgi-cmdkey must be passed in the additional paramter "hidden_run_parameters" to make the HTTP-POST to the cgicmd-key work:
hidden_run_parameters=your_cgicmdkey
It is not needed as the "first paramter" in the URL anymore. Perhaps that is due the fact, that there is no specific order on post parameters (is this true?, sounds correct ;-)
However, i still have the feeling that this is a kind of undocumented hack, as since now, i didnt find any documentation on this.
Has anyone had any expirences with this?
Regards
chris
