java.util.logging.Logger override the file data instead of add to end of file.
Is this correct? should I create 1 file for each time I initialize the app and the log system?
If not, how do I set it to write to the end of the file?
Can anyone recommend a good Java JSON library (better than the one from http://json.org/)? I've also found JSON-lib, which definitely looks like an improvement, but I'm wondering if there is anything that is even better than that?

I need to create a Set of objects. The concern is I do not want to base the hashing or the equality on the objects' hashCode and equals implementation. Instead, I want the hash code and equality to be based only on each object's reference identity (i.e.: the value of the reference pointer).
I'm not sure how to do this in Java.
The reasoning behind this is my objects do not reliably implement equals or hashCode, and in this case reference identity is good enough.

I'm developing a multiclient-server program with Java based on GUI and database. The demand regarding the program from the client side is to make sure all the time that there is a connection to the server, and if the connection is lost (server goes down/problem with socket or stream) it should be notified.
In other words I need a solution for continuously checking the connection to the server.
What is the best way to do that ?
