Hi thanks for the help...
I'll try to be more precise in this question.
Machine Config:
Windows Server 2003 R2, Standard x64 Edition,
Intel Xeon CPU E5310@1.6 GHz, 8GB RAM
I tried delpoying my 32 bit application <war file> on 32 bit tomcat
app server using 32 bit HotSpot JVM and it is running smoothly.
As i wish to eliminate the memory usage constraints on JVM, i upgraded
it to 64 bit JVM.
I couldnt find the Tomcat x64 bit installable so i followed this :
http://www.nabble.com/Mini-HOW-TO:-...-2003-64-bit-edition-tf1735687.html#a13244048
For running the Tomcat on 64 bit OS <Windows server 2003 / 64 bit Xeon
1.6GHz, 8G RAM> :
I installed the 64 bit JRE from Sun, Installed 32 bit tomcat.
Edited all the necessary values in the registry for the node
"Wow6432Node"
I copied the 64bit compiled exe from bugzilla <link given by you>.
However i'm now getting a strange error when i try to run the exe from
the command line or try to run the tomcat from the services.msc.
<Snapshot>
C:\Tomcat55\bin>tomcat5.exe

The system cannot find the file specified.
[2007-10-16 17:41:51] [1246 prunsrv.c] [error]
Load configuration failed
However the tomcat5w.exe <original> runs fine and the service window
opens up. I tried running the server from there, but no luck there/
I confirmed all the entries once again in the registry.
Have you encountered similar problem?
Please suggest input. Any help is appreciated.
Thanks in advance.
