Introduction

When to use HTTP bindings

Consider an HTTP binding when these factors are applicable: You need to access an external service over the Internet or provide a service over the Internet and you are working with other Web services based on the HTTP model; that is, using well-known HTTP interface operations like GET, PUT, DELETE, and so on. The services are loosely coupled Synchronous communication is preferred; that is, a request from one service can wait for a response from another.

Generate HTTP import from a HTTP export We will create an HTTP import binding from an existing HTTP export. Open the assembly diagram of a service requester module (i.e CCambil_Consumer_M) Drag a HTTP export (i.e DateTime_CExport) from another module(i.e CCambil_Provider_M) and drop it into the assembly diagram of the service requester module. A warning window appears (see below)
Creating Import from Export using HTTP binding A warning message is issued to do required configuration before deployment. Click OK.
HTTP Import binding generated An HTTP import binding is generated.

Generate Web Service import from a Web Service export We will create a web service import binding from an existing web service export. Open the assembly diagram of a service requester module (i.e CCambil_Consumer_M) Drag a Web Service export (i.e CCambil_DateTime...) from a library (i.e CCambil_Library) and drop it into the assembly diagram of the service requester module (i.e CCambil_Consumer_M) A Component Creation window will display (see below)
Select the type In the Component Creation window, select Import with Web Service Binding and click OK. A Web Service import binding is created.
Wire the Import Wire the service requester component (i.e CCambil_Consumer_C) to the import as required. Note: Notice that the import and export web service binding properties are identical.
