Consuming a Stateless Web Service
Use
The interface patterns stateless (XI 3.0 compatible), stateless, stateful, and TU&C/C assign the type of communication to be performed to each service interface.. Stateless communication means that the messaging runtime does not support the saving of a status at the provider once the messaging runtime has completed the message exchange successfully.
Depending on the interface pattern, the service interface editor provides you with different operation patterns and modes. Read the explanations on Interface Patterns and Operations in the documentation on the Enterprise Services Repository.
Prerequisites
●
The Web service
runtime is configured (for more information, refer to the section
Configuring the Web
Service Runtime).
●
You have generated
a proxy (refer also to
Generating a Consumer
Proxy).
● You have configured the consumer proxy.
For more information, refer to the section Configuring the Consumer Proxy.
●
The role
SAP_BC_WEBSERVICE_CONSUMER has been assigned to your user master record (refer
to the section
Authorizations).
Calling a Synchronous Service from an Application
Proceed as follows:
...
1. Instantiate the proxy class.
DATA: lv_<client
proxy name> TYPE REF TO <client proxy name>.
CREATE OBJECT lv_<client proxy
name>
EXPORTING
LOGICAL_PORT_NAME =
The logical port must be specified if no standard port has been agreed upon.
2.
Fill in the
displayed query data.
DATA: lv_<request data> TYPE <request
data>.
lv_<response data> TYPE <response
data>.
3. Call the service.
CALL METHOD lv_<client proxy
name>-><name of method / operation>
EXPORTING
INPUT = lv_<request
data>
IMPORTING
OUTPUT = lv_<response
data>
4. Edit the received data.
LOOP AT lv_<response data>
<process the data>
ENDLOOP.
The runtime supports protocols for the purpose of more specialist services.
Calling an Asynchronous Service from an Application
Read the section
Programming with
Sequences.
Testing the Client Application
You can test how the Web service behaves when it is called by an application. Select the proxy that you have generated and choose Test (F8).
