Help with accessing a user in the ThingWorx API

[TravisPickett]

I am working on a custom extension that will create users in ThingWorx.  Once a user is created does anyone know how to access that user object so the extensions can be modified?

If you are interested in the User Extensions (properties of the user as listed in the Extensions section) that is in a ThingShape called UserExtensions

Did you manage to access user extensions via Java? I am working on similar functionality right now

[JesseR.Docken]

Is this in Java or JavaScript?  If it's in Java, you can do the following:

User user = (User) EntityUtilities.findEntity(username, ThingworxRelationshipTypes.User);
