Hy Denise.
I´was in same trouble an solved that task in following way.
First you have to provide the technical environement.
Please ensure you that following components are installed. (Not sure if you need all of them)
UI2_700
UI2_701
UI2_702
UI2_731
UI2_FND
UI2_SRVC
UI5_731
UISAPUI5
UI_INFRA
then you can activate the UI2 Services in transaction SICF
/default_host/sap/bc/ui2 and
/default_host/sap/bc/ui5_ui5/ui2
next you have to load the required .js files from WebAs into you app.
e.g.
<script src="/sap/public/bc/ui2/shell-api/sap/ui2/shell/shell.js"></script><script src="/sap/public/bc/ui2/services/sap/ui2/srvc/error.js"></script><script src="/sap/public/bc/ui2/services/sap/ui2/srvc/utils.js"></script><script src="/sap/public/bc/ui2/shell-api/sap/ui2/shell/startup.js"></script>
now you have acces to ui2 shell and user properties.
Please read section 4.2.6.3 Accessing System and User Information in
https://websmp206.sap-ag.de/~sapidb/011000358700000944892012E
var oUser = sap.ui2.shell.getUser(); oUser.load({}, function(){ var fullName = oUser.getFullName(); var userID = oUser.getId(); alert('you are loggin in with ' + fullName); }, function(sError){ alert ('user fetching failed ' + sError ); });Viele Grüße,
Christoph
