Hi group,
i'm looking for a Java persistence framework that is able to cope with
changes of the class source, i.e. new/changed attributes and/or
methods. Say you have an exported (persistent) instance of a old class
version and want to reload it into a newly started program that uses a
new version of the class. Is there some framework that can do the job
or do i have a strange idea of what instance persistence realy is?

Hi everyone,
Can anyone tell me if I declare a global variable in my pages code behind,
is it persisted if the page does a post back, or do I need to add the object
to the session object in order to persist it.
Is the session the best mechnism for persisiting this object
Thanks everyone

Hi Guys,
I'm a total newbie trying to make a simple series of click buttons to load up different pages for a target frame on the low side of a page. Right now I'm still struggling with just the buttons. So far the HTML ideas I've tried have let me down so I've turned to Java and just found this script (I'll use Google as the example URL here):
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin

Or... when is a script not a script?
I have several modules for managing different aspects of our club's website,
most of which are multi-page.
Does setting such things as server.ScriptTimeout or response.buffer values
at the start of the first page persist throughout the session, or are they
"reset" with each function or sub, etc.?
TIA.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
