The code on page 55 in the OpenEdge Development: Mobile Applications book inadvertly left out a variable that must be defined in order for the sample application to create a new progress.data.Session. The variable cMsg needs to be defined and set to "ok" otherwise, the sample appication will not connect and return data.
The correct code is as follows:
var settings;
var cMsg = "ok";
try {
/* CHANGE THIS TO POINT TO YOUR SETTINGS SERVICE */
settings = MyMobileService_dsCustomer_Settings;
pdsession = new progress.data.Session();
var loginResult = pdsession.login(settings.serviceURI,"","");
if (loginResult != progress.data.Session.LOGIN_SUCCESS) {
console.log('ERROR: Login failed with code: ' + loginResult);
switch (loginResult) {
case progress.data.Session.LOGIN_AUTHENTICATION_FAILURE:
cMsg = 'Invalid user-id or password';
break;
case progress.data.Session.LOGIN_GENERAL_FAILURE:
default:
cMsg = 'Service is unavailable';
break;
}
}
}
catch (e) {
cMsg = "Failed to log in";
console.log(e.stack);
}
if (cMsg != "ok") {
alert(cMsg);
return;
}
pdsession.addCatalog(settings.catalogURI);
