I am making my first foray into CompositeConfiguration and am struggling
with some basics. I am trying to create a method that returns a
specified property or 'null' if it does not exist:
Public String getProperty(String prop) {
return((String) config.getProperty(prop));
}
The problem is that I keep getting a NullPointerException. I know it is
not 'config' that is null so the exception is a bit confusing. In any
case I also know that the value of 'prop' is a key that does not exist.
So the question really is, how do I determine that a property does not
exist so I can return a null? When I search for checking existence of a
property I get nothing useful and the docs don't seem to indicate a
solution either. TIA.
