HTTP adapter. Pls advice urgent

Hi,
Some cleint wants to send data to PI (7.0)  through HTTP.
Now should that client send through HTTP or it can also use
HTTPS.
Pls advice urgent.
Regards

Hi,
          All XI runtime components using the HTTP protocol support the encryption of the HTTP data stream by means of the SSL protocol, also known as HTTPS. HTTPS data streams are completely transparent to the Exchange Infrastructure
     HTTPS (Hyper Text Transfer Protocol Secure) is a secure version of the Hyper Text Transfer Protocol (http). Secure means of transferring data using the https protocol in the World Wide Web where secure ecommerce transactions, such as online banking transactions and other financial transactions are involved.
Https encrypts the session with a digital certificate i.e., HTTP over SSL (Secure Sockets Layer) which can be used by Web browsers and HTTPS - capable client programs.
If the website begins with https:// instead of http://, it is a secure site. Almost 99% of the browsers can connect to web servers either using http or https. The address bar in the browser will begin with https instead of http, if a web site is secured.  
HTTPS Protocol work with the combination of programs including the browser programs which takes care of the encryption/decryption routines that exist on the web hosting servers.
HTTP data is sent over TCP/IP port 80, whereas  HTTPS  data is sent over port 443.
HTTPS comes in two flavors, both ensuring the confidentiality of data sent over the network
1)Server authentication :
Only the HTTP server identifies itself with a certificate that is to be verified by the client.
2)Client authentication:
Additionally, the HTTP client identifies itself with a certificate that is to be verified by the server

    Hi Henry,
    1. Where sender partner will send his XML if he uses the above URL?
    Whatever technology , partner is using to send the data, there are some APIs available for establishing the http connection and then sending the data on this HTTP connection.
    2. How the user name and password will be sent in the above URL as XI requires User Name and password.
    You can embed in the URL by adding sap-user=xyz&sap-password=abc

  • UDF in message mapping instead of Java Mapping. Pls advice urgent

    Hi All,
    My scenario
    CRM --- XI -- CRM
    In XI I have to open socket connection.
    Pls refer link:
    /people/saravanakumar.kuppusamy2/blog/2005/12/15/socket-integration-with-xi
    Can Java Mapping code given in above link for socket connection can be used in Message Mapping (CRM -- CRM)UDF?
    Pls advice urgent
    Regards

    Hi Henry,
    I understood your requirement.
    But as per the architecture of XI/PI some message has to trigger your scenario.
    In this case there is no adapter where you can directly communicate with CRM system.
    Do one thing configure a dummy scenario on the sender side.
    Use File adapter for simplicity. once it pools the file with some dummy data in the file it comes to Interface mapping(message mapping) of the PIPELINE steps. Now use the code as you mentioned above(within UDF) for opening socket to CRM system and implement you business logic within that program and write the response to target interface which will infact talk with CRM system.
    Dont forget to do the coding in an infinite loop with some delay (if required). Other wise every time you have to put a message for File Adapter for triggering purposes.
    You can also acheive the same if you use Java Mapping instead of Graphical mapping with UDF(code for Opening socket and business logic). I suggest you to use Java Mapping.
    I dont know how you will comunicate with CRM system on receiver side.?

    Hi Piyush,
    Hi Piyush,
    System A (WebService) -- XI --- System B (WebService)
    I know the flow -- like both webservices will be impoted as External Definations and will me mapped.
    I was asking about Webserver.
    a. XI --- System B (WebService)
    System B is providing wsdl.
    WebServer is required at System B -- fine.
    b. System A (WebService) -- XI
    System A is providing WebService(wsdl) to XI
    XI is NOT providing WebService to System A.
    So It is a webservice(wsdl) of System A. It will be given to XI and XI will import it as wsdl.
    So do we or not require require Webserver in
    System A or XI?
    Pls tell System A (WebService) -- XI
    Webserver part.

  • HTTP Synchronous Scenario. Pls advice urgent

    Hi All,
    My scenario

    This is Synchronous HTTP scenario.
    I tested in XI RWB.
    a. I took Message Mapping Source xml structure and sent from RWB it worked fine.
    b. I took xsd of Request Data Type and sent from RWB it shows error
    "MAPPING">EXCEPTION_DURING_EXECUTE"
    Now In real scenario System A will send data to XI.
    So does it mean that I need to send Message Mapping Source xml structure to System A and not xsd of Request Data Type
    Pls advice

  • XI to WebService . Pls advice urgent

    Hi All,

    I need to send response from XI to System B and get response back to XI.
    System B has Synchronous Web Service and has provided its WSDL to XI.

    1. Do I need to Import Webservice WSDL as External Defination in XI.?
    2.Do I need to use only Soap Receiver Adapter in XI as it is Synchronous Web Service and XI can get response back from that System or also I need Soap Sender Adapter ?

  • Simple file to file transfer.  Pls advice urgent

    Hi All,
    I have Simple file to file transfer.
    There are text files at source side that need to send at receiver side.
    Source text files name are different so I have used
    Adapter Specific Attributes for Sender and Receiver Adapetrs
    Question
    As these are text files and there is no mapping required what interface name should I give at Sender Aggrement and
    at Interface Determination.
    Pls describe steps
    Regards

    Rider,
    Its very simple scenario. For ur satisfaction I did the same, it's working perfectly. I don't know what mistake u did. Let me give the complete picture.
    Step1: Create new Scenario
    Step2: Create new Business Service, let say File_BusService
    Step3: In File_BusService add the outbound and Inbound Interface name and namespaces , like
    Outbound Interface: MyInterface
    Outbound Interfacenamespace: http://my-own-namespace.com
    Inbound Interface: MyInterface
    Inbound Interfacenamespace: http://my-own-namespace.com
    Step4: Create two communication Channels under File_BusService
    Step5: Receiver Determination.
    Sender:File_BusService
    Outbound Interface: MyInterface
    Outbound Interfacenamespace: http://my-own-namespace.com
    Configured Receivers
    File_BusService
    Step6: Interface Determination.
    Sender:File_BusService
    Outbound Interface: MyInterface
    Outbound Interfacenamespace: http://my-own-namespace.com
    Inbound Interface: MyInterface
    Step7: Receiver agreement
    Receiver Service: File_BusService
    Inbound Interface: MyInterface
    Receiver Comm.channel
    Step8: Sender Agreement.
    Sender:File_BusService
    Outbound Interface: MyInterface

  • TCP/IP Connection. Pls advice urgent

    Hello ,

    He has given IP address and port of Non Sap System.

    2. For above HTTP Destination can I make TCP/IP Connection

    How to connect XI --- Switch (Non sap system) for TCP/IP.
    Regards

    Your information is not very helpful.
    Try to figure out, what exactly the system needs to be connected. TCP/IP is base of ANY connection between computers, this information is not useful.
    What system do you want to access? Name? Vendor? Documentation?
    What protocol is supported by the system? HTTP? XML?
    If you do not tell more about your scenario, it is impossible to help you.

    Pls explain me following Points:
    1.Do In the visual admin of XI I need to make Server Public and Private keys. ?
    2.Where in Receiver and Sender File Systems we will store XI Public key.?
    3.Where in XI system we will store Receiver and File System Public Key.?
    4. Any Certificate setup needed in XI.
    Thanks in advance

    Hi,
    The following are the answers:
    1.Do In the visual admin of XI I need to make Server Public and Private keys. ?
    yes. Depends on whether you are sender or receiver. If you are using receiver channel, then you will be provided (by the end system) with the public key and the CA certificate. You will have to install them in your key storage. If you are using the sender channel, then you will be generating the private and public key and then provide the public to the system which is sending the data to you.
    2.Where in Receiver and Sender File Systems we will store XI Public key.?
    You need not worry about where the receiver and sender file system (end systems) store the keys. In XI, you will be storing on the local file server and then upload them to the Key storage.
    3.Where in XI system we will store Receiver and File System Public Key.?
    In the key storage in the visual admin.
    4. Any Certificate setup needed in XI.
    yes. you will have to mention the key store name in the channel and in the sender/receiver agreements, you will have to mention that you are using certificates for authentication.
    Hope this helps.
    Cheers,
    Sarath.
