The 504 j.jar (Java front end) runs with a 32 bit Java JRE and communicates with the J64 engine throught sockets (i.e., a 32 bit
front end task talking with a 64 bit engine task)..
The 601 j.jar must be run with a 64 bit Java JRE as it loads and runs the J64 engine as a dll (64 bit task with 64 bit shared
library).
It looks as if you downloaded and installed the 32 bit JRE. The path
...(x86)... is for 32 bit programs.
You need to download the 1.5.0_xx that explicitly says it is for windows 64. I think the key term at the sun website is AMD64. That
install will go into the "program files" (without the (x86).
When installed the j.jar file association will still be with the 32 bit java. This should probably be left alone. You will have to
edit the icon you use to launch J64 to provide a full path to the 64 JRE javaw.exe. The icon command line should be something like:
c:\program files\java\jre1.5.0_xx\bin\javaw.exe -jar j.jar

Subject: [Jbeta] Windows 64, J64 and Java - JRE 64
Thanks for your previous response.
As previously suggested I have downloaded and installed the following
version JAVA:
jre-1_5_0_07-windows-i586-p.exe
into the
C:\Program Files (x86)\Java\jre1.5.0_07
This I think should be the latest JAVA 64 bit version. However I stand to
be corrected.
With this installation of JAVA I can load J 32 and 64 versions in the
following ways on my system:
c:\j504\jexe
c:\j504\j.jar
c:\j64_504\j.jar
and
c:\j32_601\j.exe
c:\j32_601\.jar
My system is duel AMD64 Opteron under Windows XP64.
Does the fact the I can run J64 504b , j.jar mean that I have a JRE 64 bit
version running.
Or does J64 504b , j.jar run under a JRE 32 bit version.
HOWEVER as previously tabled I am NOT able to load J64_601 as follows.
c:\j84_601\j.jar
I get no response or even an error message.
When I look at the j.jar to see what is used to open j.jar I get the
following:
Open with: Java(TM) 2 Platform Standard Edition Binary.
I am not familiar with JAVA and don't wish to be - however I would like to
be able to run J601 for both 32 and 64 bit versions.
ANY HELP WOULD BE GREATLY APPRECIATED.
Regards
Bill Szuch
