I just finished installing 64 bit tomcat (6.0.24) on 64 bit JVM
(1.6.0_18)on 64 bit OS (WIN 2008). I was able to install it as a service
without any problems.
The trick is to start with the zip file distribution (64 bit). Do not
use the windows installer as it is for 32 bit.
Here are the steps:
1. download and install the 64 bit JVM from SUN.
2. download the 64 bit distribution of Tomcat (6.0.24) winzip file
(apache-tomcat-6.0.24-windows-x64.zip)
3. extract the zip file to a desired location
4. Navigate to the tomcat/bin directory (refer to step 3 for location)
5. Create a new bat file setenv.bat (declare and set JAVA_HOME,
JRE_HOME, and CATALINA_HOME) as per your settings.
6. Edit startup.bat, shutdown.bat and to call setenv.bat first
7. zip file distribution of 64 bit tomcat comes with following 3 files
(service.bat, tomcat6.exe, and tomcat6w.exe)
8. Edit service.bat to make a call to setenv.bat - should be the first
command)
9. From a DOS/Command prompt execute service.bat with the keyword
install
service.bat install
That's all there is to install Tomcat as a service on 64 bit.
Thanks,

Subject: Re: max heap size on Windows server 64 bit
It's normal to be forced to double the heap on migrating from x32 to x64
hw.
Just think to the pointer addressing , that is based on a 64bit
representation of the memory address, rrather than a 32bit.
By the way, how did you install it as a service?
Did you find a Windows installer?
I tryed to execute the 'service.bat install' of Tomcat 6.0.24, but
doesn't
run.
Please could you help me?
Thanks
Domenico
