291.6. Examples
This example is using the flight demo example from SAP, which is available online over the internet here.
In the route below we request the SAP NetWeaver demo server using the following url
https://sapes1.sapdevcenter.com/sap/opu/odata/IWBEP/RMTSAMPLEFLIGHT_2/
And we want to execute the following command
FlightCollection(AirLineID='AA',FlightConnectionID='0017',FlightDate=datetime'2012-08-29T00%3A00%3A00')
To get flight details for the given flight. The command syntax is in MS ADO.Net Data Service format.
We have the following Camel route
from("direct:start")
.setHeader(NetWeaverConstants.COMMAND, constant(command))
.toF("sap-netweaver:%s?username=%s&password=%s", url, username, password)
.to("log:response")
.to("velocity:flight-info.vm")Where url, username, password and command is defined as:
private String username = "P1909969254";
private String password = "TODO";
private String url = "https://sapes1.sapdevcenter.com/sap/opu/odata/IWBEP/RMTSAMPLEFLIGHT_2/";
private String command = "FlightCollection(AirLineID='AA',FlightConnectionID='0017',FlightDate=datetime'2012-08-29T00%3A00%3A00')";The password is invalid. You would need to create an account at SAP first to run the demo.
The velocity template is used for formatting the response to a basic HTML page
<html> <body> Flight information: <p/> <br/>Airline ID: $body["AirLineID"] <br/>Aircraft Type: $body["AirCraftType"] <br/>Departure city: $body["FlightDetails"]["DepartureCity"] <br/>Departure airport: $body["FlightDetails"]["DepartureAirPort"] <br/>Destination city: $body["FlightDetails"]["DestinationCity"] <br/>Destination airport: $body["FlightDetails"]["DestinationAirPort"] </body> </html>
When running the application you get sampel output:
Flight information: Airline ID: AA Aircraft Type: 747-400 Departure city: new york Departure airport: JFK Destination city: SAN FRANCISCO Destination airport: SFO
