error recovery

[Amir Michail <am...@gmail.com>]

Hi,

I was wondering how a servlet should handle derby server problems. For
example, what should happen if the derby server goes down? How should
the servlet handle this situation as to not confuse the derby server
on startup and cause severe errors (e.g., that might result in an
immediate shutdown of the derby server)?

I'm assuming your talking with Derby using the network client JDBC 
driver, and that Derby is running as a separate process that accepts 
network connections?

If the server goes down, you'll get a disconnect exception and your 
connection will be invalid.  There's nothing more you need to do.  Derby 
cleans up (runs recovery) automatically on startup and then you just 
reconnect.

Does that answer your question?
