Enabling Form Submission Using HTTP 

Use

In a typical scenario where forms are used in a Guided Procedures process, the form designer should implement functionality that enables the user to submit data back to the GP framework. On the GP side, there is a servlet that receives the data and sends it for further processing.

Prerequisites

Sending data from a form to the GP system is possible when parameter http.server.base.url of service caf/eu/gp/model is configured to the appropriate value.

Activities

To enable the processor of the form to return data to the system, you include a button and specify the following parameters in the form:

·        On the Object → Field tab select Submit from the Control Type dropdown box

·        On the Object → Submit tab select PDF from the Submit Format dropdown box

·        In the Submit to URL field enter the following string:

%com.sap.caf.gp.if.PostProcessorUrl%

The server-side information that determines the server address, such as host name, HTTP port, and so on, is retrieved when the form is generated from the form template. At runtime, when the user submits the form back to the system, the above URL string is replaced by the relevant server-side information, and the data is sent back to the server in XML format.
