Well you can't call a method on null! null is not a String with value
"null". It's a special value in java - basically a reference to a value
called null (i.e distinct from an undefined variable that has no
reference assigned). You need to check for a null value before calling
any methods:
if(user.getUserType() != null &&
user.getUserType().equalsIgnoreCase("Admin")) {
....
