HTTP request handling at server

I am in the process of developing a backend component that analyses the http requests. I have a few doubts:
- If http POST method can have multiple entity-bodies, what is the value of top level Content-Length header ?
- Is Content-Length header allowed with GET request ?

These questions are not really in the scope of this forum. This isn't a "how does HTTP work" forum.
That being said [_here's the spec,_|ftp://ftp.isi.edu/in-notes/rfc2616.txt] enjoy.

Problem in sending HTTP request to the server.

Hi,
i dveloped an ant script for sar deployment.
i deployed a sar to my local soa server with ant script. it got deployed succesfully..
but when i try to deploy to a remote server, getting the below error..

You can also use the HTTP-DC project.... You don't
need Web Enterprise for this. From what I can tell,
this is available in L.x on....
There is api documentation in M.2 (with scant
examples.)
There's a special process to put the project in your
repository (it isn't installed in the repository in
the standard install,) the documentation in M.2
(probably in M.0 too, AFAIK) that tells you how to do
this (look for HTTP-DC in the online help.)
I haven't done much with it yet, I've just installed
it. If anybody out there has examples, that'd be
great. I'll try to contribute more the moment I get a
chance to explore it....

HTTP Request to Integration Server through ABAP Mapping

Hi Experts,
I need to send HTTP Request to Integration Server through ABAP Mapping.
Could you please provide me ABAP code which will post data to Integration Server.
Thanks,
Abdur

Hi Abdur,
Can you explain your requierement more clearly?
Abap mapping is purely to convert the data in source structure to data in target structure.
It is not the job of Mapping to send data.

Its urgent...How to implement functions in http request handler ?

Hello experts,
I have created http request handler class and also created service in SICF.
service and handler class are connected. please guide me how to implement info, get, create, delete functions in request handler.

Hi,
It seems you go on your way of http basic programming where you need handle the request of info, get, etc. But here you have WDA framework, so you don't need do as the basic ways of http programming. SICF can handle the activated WDA applications, maybe you can call them SERVICES.
I suggest you go through WDA architecture, tutorials, ... and at last you can find a full demo 'LORD_MAINTAIN_COMP' by SE80.

How to Intercept Http requests by Application Server plugin ?

Hi all,
My requirement of "Application Server plugin/filter" is to intercept all Httprequests coming to an
Application Server instance (and not webserver), get the related information from the request, do whatever
i want to do and then forward the request based on the info available in the request header to any webapplication or EAR deployed in the application server.
I do not want to implement as a Servlet filter in a webapp. which is intrusive to the webapp.
as we are aware, Servlet Filters can be attached to resources in a Web application and are configured in the web.xml file.
I have tried out my requirements in Tomcat as follows, it works:
In Tomcat, Valves are attached to a Tomcat container and are configured using a <Valve> element in the server.xml file.
We have modified RequestDumperValve Filter ( source available) class extending Valve to intercept Http requests.
I perform whatever i want to do in this custom Filter and then able to forward to the next valve in the valve chain of Tomcat container. I have Configured this valve in server.xml and it works fine.
My queries are:
1. Can i do it the same thing in SunONe application server or other IBM Websphere application server ?
2. Do the commercial appservers expose their APIs ( e.g. like Valve in Tomcat ) such that i can implement an application server plugin ?
i.e. Are there any such Filter classes available which will intercept the Http request processing pipleine
in application server ( precisely, its web container )
If so, can you pls provide pointers for SunONE application server and IBM Webpshere application server
3. Is this against J2ee specs ?
Appreciate if you can provide me any clues, tips, solutions, pointers regarding this problem.
thanks and regards
rajesh

Thanks for the info, vbk.
Actually we are looking filers not at the servlet level in a web application.
We are looking ways for the filter to work at web container level across different web applications... That is whatever comes to the application server, should hit at this filter ,then we perform some processing, analysis and then continue for the correspnding web application
thanks

Air application throws security alert every time 'HTTPS' request made to server.

Have a look at the following screenshot.
On click of next button, application internally sends an https request. Appliction throws Security Alert dialog. The text can also be seen clearly.
Strange thing about this alert dialog is that, it appears every time when application send a request in given session.
If I run the same thing in flex (i.e. in browser), it asks for SSL handshake and that is also only once. So why it is happening here in case of Air.

If Safari crashes immediately on launch and you can't do as above, hold down the shift key and launch it by clicking its icon in the Dock, then try. Failing that, ask for guidance.

How do I send HTTP request to a server via a proxy server in JDK 1.4?

JDK 1.5 's URL class provides an overloaded version of openConnection() which accepts an object of type Proxy using which we can establish connection with a remote server via a proxy server, but JDK 1.4 doesn't provide any such overloaded version. How do I do that in JDK 1.4? Even if I had a class that can create HTTP packets for me, then I could have established Socket connection with the proxy server and sent the HTTP packet to it. Is there a way to do that also?

There are some system properties, which can be set with System.setProperty [http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html]

File.upload on Air SDK for iOS devices failed to send http request to server.

I am trying to use ActionScript's File.upload to upload a file on Air SDK for iOS8 environment, but the File.upload does not work properly. No handler about the file upload is executed after File.upload is invoked, and no exception is caught. When I check the network traffic of the server side, I found that no http request even hit the server after File.upload is executed. The code snippet here is very simple.
private var file:File;
private var dir:File;
//This method is executed to create a file and upload it when the Upload Button is pressed.
protected function OnUploadButtonPressed(event:MouseEvent):void{
var str:String = 'This is test';
var imageBytes:ByteArray = new ByteArray();
for ( var i:int = 0; i < str.length; i++ ) {
imageBytes.writeByte( str.charCodeAt(i) );
try{
dir = File.applicationStorageDirectory
var now:Date = new Date();
var filename:String = "test" + now.seconds + now.milliseconds + ".txt";
file = dir.resolvePath( filename );
var stream:FileStream = new FileStream();
stream.open( file, FileMode.WRITE );
stream.writeBytes( imageBytes );
stream.close();
file.addEventListener( Event.COMPLETE, uploadComplete );
file.addEventListener( IOErrorEvent.IO_ERROR, ioError );
file.addEventListener( SecurityErrorEvent.SECURITY_ERROR, securityError );
file.addEventListener(ErrorEvent.ERROR, someError);
file.addEventListener(ProgressEvent.PROGRESS, onProgress);
file.upload( new URLRequest("http://10.60.99.31/MyPath/fileUploadTest.do"));//This line does not work. No handler is executed. No http request hit the server side.
} catch( e:Error ) {
trace( e );
//Complete Handler
private function uploadComplete( event:Event ):void
trace( "Upload successful." );
//IOError handler
private function ioError( error:IOErrorEvent ):void
trace( "Upload failed: " + error.text );
//SecurityError handler
private function securityError(error:SecurityErrorEvent):void{
trace( "Security error:" + error.text );
//Other handler
private function someError(error:ErrorEvent):void{
trace("some error" + error.text);
//Progress handler
private function onProgress(event:ProgressEvent):void{
trace("progressHandler");
When executed on Air Simulator, it works fine as expected, and the file is successfully uploaded to the server. But When executed on iOS devices(in my case, iPad), as I explain early, no handler about the file upload is executed, and no the http request even hit the server. So I think the problem may be in the client side. It seems that the Air SDK for iOS just failed to send the http request for some reason.
To make my problem more clear, I list my environment below:
Development Environment: Windows7 (64bit) / Mac os 10.9.4 (Tested on OS platforms.)
IDE: Flash Builder 4.7
Air SDK: 3.8 / 16.0.0 (After I updated to the lastest Air SDK 16.0.0 , the problem still exists.)
Application Server: Tomcat7 + Spring
Target OS: iOS 8
I have been struggling for this for days. So I really appreciate it if anyone has any idea about this.
Thanks in advance.

Hi bluewindice ,
As you have quoted ( ActionScript's File.upload does not work on Air SDK for iOS devices ) , this issue has been replicated at our end, and our team will be working on it.
Thanks,

Problem with HTTPS requests to host with untrusted server certificate

Hi,
I develop an iPhone framework which sends HTTPS requests in order to communicate with a publicly available backend server. Currently I have a big problem regarding untrusted server certificates.
The certificate of the backend server is not signed by a trusted CA, so my first approach was to use NSURLRequest's private allowsAnyHTTPSCertificateForHost. While this worked as expected an was fine as temporary workaround, our customer demands a clean solution as final result. Therefore I wrote a method which allows to install a provided certificate from the file system in the keychain, but this method does not work as expected in the iPhone Simulator. The certificate is installed in the host machine's Mac OS X keychain instead. Unfortunately, if I call NSURLConnection's sendSynchronousRequest method, I retrieve an "untrusted server certificate" error. It seems as if NSURLConnection is not able to access the host's Mac OS X keychain to retrieve the certificate.
Is my guess correct or did I miss something?
Would my approach work if I ran my app on a real iPhone device instead (I do not have one available yet)?
Does there exist a keychain in the iPhone Simulator at all?
Is it at all possible to send HTTPS requests to a server with an untrusted certificate on the iPhone Simulator or do I have to use precompiler directives to implement different routines depending on the underlying platform (simulator or device, respectively)?
Any help is highly appreciated.
Thanks,
Matthias

Indeed this would be a clean and simple solution. But our customer is not willing to get a real certificate, for whatever reasons.
The question that remains is if the HTTPS requests would succeed on the iPhone device itself if the server certificate was installed in the keychain by the same app beforehand.

The request is cached by first HTTP request handler.
at the end it returns the response.
it does not reached the second HTTP request handler.
how can i forward my request to second HTTP request handler.

BPM: IDoc to multiple HTTP-Requests

Hello!
I'm currently working on a scenario which is described as followed:
My XI-System is receiving an IDoc from an SAP R/3-System.
This IDoc contains a list of numbers together with the respective name of the customer an our internal customer number.
Structure:
IDoc
|
area01
   |
   |-NUMBER01
   |
   area02
     |
     |-NUMBER02
     |-CUSTNAME
     |-CUSTNUMBER
This IDoc has to be split up in HTTP-Request to a server in the WWW. Each HTTP-Request consists of an URL together with two specific parameters (eg: http://www.xyz.com?param1=P1&param2=P2, where param1 is NUMBER01 from the IDoc and param2 is NUMBER02)
I have two different problems:
First one is that my BPM is showing errors with the transformation step (IDoc to single HTTP-Requests). It shows the "Expression must return the interface type xxxx"-error. I have mapped the incomming-IDoc into a abstract interface IDoc, as described in other topics.
What is to be done, to convert the incooming IDoc into several HTTP-Requests? How can i solve this issue?
Second one is the HTTP-Request itself.
I've read the hints about the adapter specific settings and tried the HTTP-Request in a little "extra"-scenario. But it didn't work very well...I other words: It did nothing. How to map the two parameters to my specific HTTP-parameters?
If I have to describe something more detailed, please let me now. I appreciate any suggestions!
Many many thanks in advance,
Roman Scholz

Hi Roman,
>"Expression must return the interface type xxxx"-error.
The target of your interface mapping has to be the abstr interface used for BP container.
