Good day,
I would like to ask about following.
How is java.util.Date synchronized in case there is more than 1
instance of my web application.
Example:
WebAppInstance01 : I create somewhere new Date()
at the same time
WebAppInstance02: I create somewhere new Date()
Is there some time shift ?

Can you post your code?

Hi,
I read in a post that the length of member variable names contributes
to the amount of storage space your app uses, example:
class Farm {
private String mFarmersFavoriteCropToPlant;
}
would take more space to store than:
class Farm {
private String m;
}
I believe some people maintain their own request count by ip address
using memcache and restrict access using a filter.

My 2 cents: if all your users are of type Person and it's a root
