EAI HTTP Transport-Session 1

HTTP transport is one of the largest mechanism through which integration happens between Siebel and other Application. This happens in two modes.

The Scenario:  We have a client which is going to send a request to other system which we will call as Server.

1)      Session less Mode –

a)  In this mode there is a connection which gets established to the server using the Login Credentials, the message or request is submitted to the server and then logs out it.

b)    The session only last as long as it takes to submit the request.

c)   For every request a new session gets created and authentication happens every time.

2)      Session Mode –

a)   In this mode the client or the request sender Logs in using the user credentials and will get an Id (i.e. Session Id).

b)   This Id is then used by client to communicate to server whenever it needs to send request (send/request data) to server.

c)   In this mode the session remains active for some time and after session the client gets Logged Off.

EAI HTTP Transport:

The EAI HTTP Transport uses one of the following two methods with this transport:

a)   Send - This method supports outbound messages (XML documents sent from a Siebel application to an external system).

b)    SendReceive - This method supports outbound messages (XML documents sent to a Siebel application from an external system). This method is called Send and Receive a Response and the HTTP response body is the response for the request.

GET and POST in Siebel - Get and Post both values are used to send the request to other system. However when we have to send small data we use GET and whenever the data is large or requires any data base operation we use POST.

Demo Outbound HTTP Transport Send method in Session Less Mode.

Send method in session less mode –

Input Argument:

a)   <Value> -  This is a required argument for this message which contains the message which needs to be send to the external system.

b)   HTTPRequestMethod – This is an optional parameter but it is uses to send the message.

c)  HTTPRequestURLTemplate – This is an optional parameter but this template is used for specifying the URL for data Request(Provided by the external system).

Send Receive method in session less mode -

 Input Argument:

a)    <Value> -  This is an optional argument for this message which contains the message which needs to be send to the external system.

b)   HTTPRequestMethod – This is an optional parameter but it is uses to send the message.

c)  HTTPRequestURLTemplate – This is an optional parameter but this template is used for specifying the URL for data Request (Provided by the external system).

Output Argument:

d)  EndOfData – Returns True if end of data has been reached.

e) TimedOut – Returns True if receive timed out and no data was available. False if request completed.

Demo Outbound HTTP Transport Send method in Session Mode.

In Session mode as we create a session and for it some are the key parameters to login to external system, Send the Request and Log Out of the system.

Send method in session mode –

Send method in session mode –

Input Argument:

a)  <Value> - This is an optinonal argument for this message which contains the message which needs to be send to the external system.

b)  HTTPRequestMethod – This is an optional parameter but it is uses to send the message.

c) HTTPRequestURLTemplate – This is an optional parameter but this template is used for specifying the URL for data Request (Provided by the external system).

Additional Arguments needed for session mode.

d) HTTPLoginMethod – This is optional HTTP Method to use for Login. Defaults to RequestMethod

e) HTTPLoginURLTemplate - Template for specifying URL for Login request.

f)  HTTPLogoffMethod – This is optional HTTP Method to use for Logoff.  Defaults to LoginMethod

g) HTTPLogoffURLTemplate - Template for specifying the URL for Logoff request.

f)    HTTPLogoffMethod – This is optional HTTP Method to use for Logoff.  Defaults to LoginMethod

g)   HTTPLogoffURLTemplate - Template for specifying the URL for Logoff request

Note: I have not given the User Name and Passwords and leave it for you to explore how to provide them.

Output Argument:

h)   EndOfData – Returns True if end of data has been reached.

i)    TimedOut – Returns True if receive timed out and no data was available. False if request completed.

In this post I have talked about sending the data from Siebel. In the next coming post I am going to talk about the Receiving the data in Siebel.
