You are correct, although one can attempt to cheat a bit and get access to private material by calling the AccessibleObject.setAccessible() method to force an override. (will work unless the JVM has had its SecurityManager permissions tightened up a bit :) )

Howdy, Another take on this is BeanUtils#describe(Object bean) which returns a Map of properties. Java.util.HashMap's toString() method prints out very nicely, so you don't have to do much work here. (I'm talking about jakarta-commons-beanutils of course ;))
A downside to both the above and I assume Senior Larmee's approach is that they only invoke public methods, so you don't get private state in your logging output.
