Web Services (SOAP) Input and Output Adapter

The Web Services (SOAP) Input and Output adapters are SOAP Web services clients which connect to a Web service to obtain data to feed into Event Stream Processor and deliver output from Event Stream Processor to a Web service.

Both adapters include an adapter configuration file and a mapping file. Use the adapter configuration file to set up the SOAP Input and Output Transporter modules, the ESP Publisher and Subscriber modules, as well as establish a connection to Event Stream Processor. Use the mapping file to map Web service WSDL to ESP columns.

You can either manually create a mapping file or use the schema discovery functionality in Studio to automatically create one. See Discovering Schema and Creating a Mapping File for the Web Services (SOAP) Adapter in the SAP Event Stream Processor: Studio Users Guide for detailed instructions on creating a mapping file in Studio.

Commands specified in the cnxml file for this adapter cannot contain the following strings: "mv", "rm", or "del".

Note The adapter does not support schema discovery if you are using HTTP Basic Access Authentication.

These adapters can run in managed or unmanaged mode.

Managed external adapters:

Are started and stopped by the ESP server with ESP projects.
Have a cnxml adapter configuration file that is configured within SAP Event Stream Processor Studio.
Are referenced in a CCL ATTACH ADAPTER statement.

Unmanaged external adapters:

Start and stop independently of the ESP server and ESP projects.
Are configured independently.
Are not referenced in a CCL ATTACH ADAPTER statement.

The Web Services (SOAP) Input adapter:

Calls or polls a Web service
Parses and converts the response into Event Stream Processor data format
Feeds data into ESP streams

The Web Services (SOAP) Output adapter:

Connects to a Web service
Converts Event Stream Processor data into Web services request format (for example, XML)
Outputs Event Stream Processor data into a Web service

The Web Services (SOAP) Input and Output adapters report custom statistics. Enable the time-granularity option in the project configuration (ccr) file to get these statistics reported by the _ESP_Adapter_Statistics metadata stream.

The Web Services (SOAP) Input adapter reports these statistics:

AdapterRunningTime
TotalInputRowsNumber
SuccessInputRowsNumber
ErrorInputRowsNumber
InputLatency

The Web Services (SOAP) Output adapter reports these statistics:

AdapterRunningTime
TotalOutputRowsNumber
SuccessOutputRowsNumber
ErrorOutputRowsNumber
OutputLatency
