Hi Greg,
Not quite. I don't have any keys set yet so I don't know about the first
line. I am only at the beginning of this and my first step was to
determine if a property exists and if not set it. I switched back to
using 'getString' but have the same exception. FWIW, here is the full
traceback.
Exception in thread "main" java.lang.NullPointerException
at
org.apache.commons.configuration.CompositeConfiguration.getProperty(CompositeConfiguration.java:261)
at
org.apache.commons.configuration.AbstractConfiguration.resolveContainerStore(AbstractConfiguration.java:1171)
at
org.apache.commons.configuration.AbstractConfiguration.getString(AbstractConfiguration.java:1038)
at
org.apache.commons.configuration.AbstractConfiguration.getString(AbstractConfiguration.java:1021)
at KCBSConfig.getProperty(KCBSConfig.java:21)
at ImageTest.main(ImageTest.java:7)
Just to be sure, I added an "if (config==null) .." to my code and it
fails that so 'config' must contain something. If this is a Java issue
rather than misuse of CompositeConfiguration, I'm stuck.

Thanks for the reply. I had 'getString' originally and got the same error
So just to confirm,
String foo = config.getString(keythatexists);
String bar = config.getString(keythatdoesnotexist);
is throwing a NullPointerException on the second line?
If so, that sounds like a bug as it should only throw a
NoSuchElementException - and that only if
setThrowExceptionOnMissing(true) is called.
