Accessing a service

In EGL, you can access several different types of services. To learn the access procedures, see the links in the following table.

Goal	Tasks
Access a dedicated service	Declaring a variable to access a dedicated or local EGL service. Then, complete either of these tasks: Invoking a service asynchronously from a Rich UI application. Invoking a service synchronously from outside of Rich UI; but this option is not available in version .7.
Access an EGL REST-RPC service or third-party REST service	Creating an Interface part to access a REST service. Declaring a variable to access a remote service. Add a REST binding: If you are using the EDT IDE, follow the process described here: “Adding a REST binding to the EGL deployment descriptor.” Otherwise, add the REST binding as described here: Editing the EGL deployment descriptor manually. Then, complete either of these tasks: Invoking a service asynchronously from a Rich UI application. Invoking a service synchronously from outside of Rich UI; but this option is not available in version .7. For details on accessing an EGL REST-RPC service from logic written outside of EGL, see EGL REST-RPC message structure.

Tasks

Access a dedicated service

Access an EGL REST-RPC service or third-party REST service

Creating an Interface part to access a REST service.
Declaring a variable to access a remote service.
Add a REST binding:
- If you are using the EDT IDE, follow the process described here: “Adding a REST binding to the EGL deployment descriptor.”
- Otherwise, add the REST binding as described here: Editing the EGL deployment descriptor manually.
Then, complete either of these tasks:
- Invoking a service asynchronously from a Rich UI application.
- Invoking a service synchronously from outside of Rich UI; but this option is not available in version .7.
