In EDT version .7, a service is accessible only from a Rich UI application, and your task follows this pattern:  declare a service-access variable and use it in a call statement.

Accessing a dedicated service

<source lang="java">

    // use the Service or Interface type to declare the service-access variable 
    myService MyServiceType?{@dedicatedService};

    // call the service

</source>

Accessing an EGL REST-RPC service

Accessing a third-party REST service

// From a a Access a dedicated service
 
 
 
 
 
 
 
http HttpRest{request.uri="http:host\\myService"};
srvc IRest?;
srvc = ServiceLib.completeBind(srvc, http);

Accessing HTTP request headers

http HttpRest{};
http.request.headers = new Dictionary { param1 = "a value to pass to my service" };
srvc IRest?{@Resource {}};
srvc = ServiceLib.completeBind(srvc, http);

HTTP request and response

function invokeDoSomething()
    call srvc.doSomething() returning to serviceCallback;
end
 
function serviceCallback(returnValueOne String, callbackHttp IHTTP in)
  // process callback request or response
end
