Proxy to HTTP comm

Hi ,
I have an Scenario where SAP ECC is communicating with HTTP in synchronous fashion. My requirement is that HTTP supports only Get() where as XI supports the Post() function.I need a synchronous Communication between them.....
Any Help is highly Appreciated.

Safari cannot open the page ~ The error was: "There was a problem communicating with the web proxy server (HTTP)

Help! I was cruzing along just fine and went out tonight only to receive the message above:
Cannot open Page
Safari cannot open the page
The error was: "There was a problem communicating with the web proxy server (HTTP)."
I have had all the Apple iPhone phone. Have never encountered anything like this.
All systems are GO as soon as I log on to wifi.
Can anyone help, please.

I am also fixed. I also loaded Onavo, but that was the other day ... this is what I did with the help of online chat with AT&T ...
I went to:
Settings
Wifi
I selected the network I was working on by hitting the blue arrow located on right side
At the detail page of that network I scolled down to the bottom to find HTTP Proxy boxes
I was on Off and changed it to Auto and it worked!
I was soo jazzed!!
Instructions said if it was already on AUTO, to change it to Manual and make your Port = 80 but I didn't have to do that!
YIPPIE!! I'm a new man!!
Go to settings -----> WI-FI -----> select the network you're using ------> hit the blue arrow located on the right-side of the network name (ie: show details of that network), this takes you to another page.
--------> at the bottom of the page you'll see "HTTP Proxy" boxes (located below the "renew lease" button) ---------------> change the proxy to AUTO. Note: if you're already at AUTO, change it to "Manual" and make your Port = 80.

ABAP Proxy to HTTP Synchronous

What I understand is the target HTTP server sends a error response because my request xml data is not valid
How do I structure my response message type and how do I map this response to the calling ABAP Proxy. The target HTTP server says if the data is fine they will send a success message in the http header, how do i map this response from http header back to calling ABAP Proxy.
Thx in advance
Ravijeet

Hi Abhishek,
The target http server says that if my xml request data is valid then they will send a response back in the http header in a field call route.
And if the xml request data is not valid then they will throw an exception, which I am getting from the target http server as below in SXMB_MONI :
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

Using URL Parameters with HTTP Comms Channel

Hi,
I need to build a new interface (HTTP - RFC) which will use several URL parameters. I've created a HTTP communications channel and Sender Service and this works. I'm able to define several URL Parameters by checking 'Adapter-Sepcific Message Attributes' and then 'Apply URL Parameters' then specifying the individual parameters.
This is straight forward so far but in usual SAP fashion the documentation on HTTP Comms Channels and URL Parameters is non existent. My question is how do I use these parameters once they are passed. I need to use the values as input parameters for the RFC which means I'll need to map these in the Integration Repository I can't find anything on SDN or SAP help that answers the question.
I know I could include these values in the XML payload but that would mean my 'customer' would need to amend their application and I'd rather keep things as they are.
Looking forward to your replies.
Thanks in advance.

May be this could help you to refference . .
For each process template, you can define interactive or composite form reference objects that can optionally be executed at runtime.
To be able to see and execute the reference object at runtime, you must add an appropriate runtime view.
Prerequisites
You can only attach standalone interactive forms to a process. For more information, see Interactive Form Types.
Activities
To attach an interactive form to a process:
       1.      Open the gallery and select a process template. To open its design time, choose Open
       2.      To switch to edit mode, choose (Edit).
       3.      Open the Forms tab page.
       4.      Choose Add and select the type of reference object you want to add. You can choose between Callable Object and Development Object.
Browse and select the reference object, and choose Add once again.
       5.      Repeat step 4 to add more objects.
       6.      To define parameter mapping, select an entry and choose Map Parameters. Select a parameter from the left-hand table, and then select the parameter you want to map from the right-hand table. This groups the input parameters of the form reference object to the relevant input parameters of the process.
If the process does not define input parameters, you can set default values.
       7.      When you have defined the required mappings, choose Done.
       8.      Whenever a newer version of the form reference object is available, its status on the Forms tab page changes to (Deprecated). To update the object, select it from the list and choose Update. The status changes to (Active).
Parameter mapping is preserved unless the parameters of the new object version are different. In this case, you need to define mappings again.
       9.      Finally, choose (Save).

ABAP proxy to HTTP sycnchronous scenario.

Hi All,
I have an ABAP proxy to HTTP syncronous scenario in which the proxy through PI makes an HTTP request to a third party to download a PDF.Once the PDF is sucessfully downloaded we need to send an acknowledgement to ECC system that the download was sucessful and also place the PFD file in an FTP server as well.
Looking forward for any possible ways that the above scenario could be achived in once interface.We are open to use ccBPM to achive this.
Thanks in advance.
Best Regards,
Bhanu.

Hi Bhanu,
if this is a sync request to a HTTP receiver (to initiate with the request a PDF upload) you will expect to get a response back to the Proxy sender.
So following the described implementation the response will provide the information about un/successfull PDF load
from the http receiver (so this partner has to provide a response in a sync connect!!!).
If you need the PDF to be moved back to a location near to the proxy sender additionally to the response message the receiver of the proxy trigger has to return both in the sync response but the proxy is not able to receive an attachment.
And... as I know HTTP adapter does not allow to handle attachment. This is only possible with SOAP !
So in such a case the PDF needs to be provided with another adapter (which would allow to use a sync connect Proxy-> HTTP and another one async from the PDF loader via file adapter (file -> file). So this will not require a BPM too!
a) Proxy-> PI -> HTTP (sync)
b) FTP -> PI -> FTP (async)
Result: No BPM required!
Regards
Dirk

HTTP Comms Channel and UTL Parameters

Hi,
I need to build a new interface (HTTP - RFC) which will use several URL parameters and I have a few questions
1) In my limited experience I know that HTTP scenarios don't usually require a comms channel. Like RFC it's built into the ABAP stack. If I create a HTTP comms channel for a particular service does that mean that any interface that is part of that specific service will use my HTTP comms channel? In other words all I need to do is create a comms channel for a particular service and it will be used.
and secondly....
2) Creating the parameters in the comms channel is straightforward. I check 'Adapter-Sepcific Message Attributes' and then check 'Apply URL Parameters' then specify the individual parameters. Straight forward so far but in usual SAP fashion the documentation on HTTP Comms Channels and URL Parameters is lacking to say the least. My question is how do I map those parameters in the Integration Directory.
Looking forward to your replies.
Thanks in advance.

OK, so once I create a sender agreement then my HTTP CC will be used? That makes sense.
In regards to the second question - As I said in my posting I want to use several URL parameters. For example sending the date as part of the URL rather than the payload. These parameters are specified as part of the comms channel but mapping the parameters to the RFC must be performed in the Integration Directory. So I'd like to understand how I do this.
Thanks

Unknown proxy type : HTTP

Hi,
We have an application based on Java web start, JNLP it works fine when no proxy is set. when we set the proxy in firefox ( the same is taken up by javaws ) we get the below error:
Could not access HTTP invoker remote service at [http://host:7001/...service ]; nested exception is java.net.SocketException: Unknown proxy type: HTTP
We are stuck here. Any pointers or suggestion would be highly appreciated.

I have a similar problem when trying to connect to a different online programme ( an online database) using Vista Business.
Other users have got around it by adding the URL of the server or the site to their list of sites not to use a proxy server for in their web browser.
Unfortunately I can only get online through a proxy-server so adding it to this list means I wont be able to connect at all.

Safari can't connect to the web proxy server (HTTP)

Hello,
I have following problem. I need to connect to the internet using a proxy server. I went to System Preferences/Network/Wi-Fi/Advanced.../Proxies. Then, I selected Web Proxy (HTTP) and enetered server's IP address and port. It looks like I did everything correctly, but Safary can't open any page because "Safari can't connect to the web proxy server (HTTP)". Does anyone know how to solve this problem?

There are three possibilities:
1. You entered the wrong address and port number for the proxy.
2. You entered the wrong user name and password, if applicable.
3. The proxy doesn't work or is incompatible.

Proxy Server / http redirect problem

I am trying to use a WLS instance as a proxy server for another WLS instance.
I have configured the weblogic.properties file as follows:
weblogic.httpd.register.proxy=weblogic.t3.srvr.HttpProxyServlet
weblogic.httpd.initArgs.proxy=redirectURL=http://url:port
weblogic.httpd.defaultServlet=proxy
However, I try to serve the page, I get a 404 error.
The odd thing is though, if I submit the URL without the page name, I am redirected to show the index listing of the remote server!
Am I missing something?

Hi Paul,
As it sometimes works & throws error in some cases, I would recommend you to try restarting the application server.
Also, as there is some version related issue, you can also try to re-deploy the webservice (I think you are exposing the EJB as webservice), restart the server, deploy new archive & run the application.
Hope this helps you.
Kind Regards,
Nitin

Proxy error - HTTP status code 500

Hi,
Scenario: Asynchronous Proxy (R/3 4.7) to 3rd Party (JDBC)

Hi,

OSB call to remote Web Service via https proxy and https CONNECT problem

Hi
I have a service that calls a web service on another server as a web service. This call is via https and the certificate validation raises no errors.
I now want this call to go via a squid httpd proxy on port 3128 on some machine. So I would like to use HTTP CONNECT (RFC 2817) proxying,. But when I set up this as a proxy, I am getting "Certificate chain" error messages. The certifcate chains is no different now from when I called without the http proxy, so what am I doing wrong? Does OSB support HTTP CONNECT?
-Johan

The exeption we are getting is BEA-380000
General runtime error: [Security:090477]Certificate chain received from XXX - 123.123.123.123 --> test.salesforce.com was not trusted causing SSL handshake failure.
This is of course not relevant if the callout were using CONNECT. In the CONNECT scenario, OSB would not care about XXX's certificate.

ABAP Proxy throws HTTP-400 error

Hi,
I've created an ABAP Proxy/Enterprise Service in ECC6.0 to consume a webservice that is created in NetWeaver 2004s. Now, when I want to test the proxy, it gives me the error message:
SOAP:1.007 SRT: Unsupported xstream found: ("HTTP Code 400 : Bad Request")
The error originates from class CX_AI_SYSTEM_FAULT
I don't know if it is related to the proxy or with some system settings on ECC 6.0/Netweaver2004s.
Any help or document reference is appreciated.
Regards.

I investigated a little and here are a couple of things you could try:
- In note 1139406, they are talking about a scenario with HTTP error 404... I realize it is different than the 400 you get, but it may be worth checking if you have a similar problem as described there - it may give a clue what your problem is.
- Try to check if the endpoint URL to which the request is sent is correct... it may be missing the style parameter, like ?style=document. Go to SOAMANAGER and take a look at the system settings, perhaps there is a wrongly formulated URL that is missing the style parameter.
Hope this helps a little...

OSB Proxy service HTTP kerberos authentication

Is it possible to use kerberos authentification in OSB Proxy service?
I need it in following scenarios.
First scenario. We have Sharepoint Portal with Windows SSO. Our Sharepoint developers can invoke webservice on OSB (proxy service) with transfering of kerberos ticket (they talk about process named impersonation). In OSB proxy service I want to know credentials which are passed in kerberos ticket. How to do it? My Weblogic and OSB Consoles already have kerberos auth.
Second scenario. How can I pass kerberos ticket from proxy service to business service without knowing info in this ticket. Like passthrought for basic auth.
PS I had read info here: http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/security/security_faq.html and paragraph about OSB SSO looks bad for this task...

For weblogic console i had done several actions for enabling of kerberos auth... some of them are:
- NegotiateIdentityAsserter was added to realm's providers,
- web.xml of consle was configured in section ...<login-config><auth-method>CLIENT-CERT, FORM</auth-method>...
etc...
What actions i need to do for proxy service?
PS Manoj sorry... wait... i missed your link before have not read info yet :) may be it will help...
