What is the difference between NoClassDefFoundError and ClassNotFoundException?
What causes them to be thrown? How can they be resolved?
I often encounter these throwables when modifying existing code to include new jar files. I have hit them on both the client side and the server side for a java app distributed through webstart.
Possible reasons I have come across:
packages not included in build.xml for the client side of code
runtime classpath missing for the new jars we are using
version conflicts with previous jar
When I encounter these today I take a trail-and-error approach to get things working. I need more clarity and understanding.
