What's my JVM bitness?

Code:

/apps/wls/bea10/jdk160_05/bin/java -d64 -version
execve(): No such file or directory
Error trying to exec /apps/wls/bea10/jdk160_05/bin/sparcv9/java.
Check if file exists and permissions are set correctly.
Failed to start a 64-bit JVM process from a 32-bit JVM.
Verify all necessary J2SE components have been installed.
(Solaris SPARC 64-bit components must be installed after 32-bit components.)

/apps/wls/bea10/jdk160_05/bin/java -d32 -version
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) Server VM (build 10.0-b19, mixed mode)
 
 
uname -a
SunOS mypc 5.10 Generic_144488-07 sun4v sparc SUNW,SPARC-Enterprise-T5220

How can script to check if my JVM is 32 bit or 64 bit?

Note: I need to check this from a remote JVM or unix script as I cant deploy my code on a running JVM.

Regards,
Mohtashim

NAME

       wrapper - Jar daemon wrapper

USAGE

	 wrapper <command> <configuration file> [configuration properties] [...]
	 wrapper <configuration file> [configuration properties] [...]
	    (<command> implicitly '-c')

	 -?  --help    print this help message

       <configuration file> is the wrapper.conf to use.  Name must be absolute or relative

       [configuration properties] are configuration name-value pairs which override values
	 in wrapper.conf.  For example:
	 wrapper.debug=true

	 Please note that any file references must be absolute or relative to the location
	 of the Wrapper executable.

JAVA WRAPPER SERVICE DESCRIPTION

	The Java Service Wrapper makes very easy to install a Java Application as a
	daemon process on Unix systems. The Wrapper monitors a JVM (Java Virtual
	Machine) process and automatically restarts it if it that the JVM has crashed
	or hung. This process takes just a few seconds once the Wrapper has decided
	there is a problem. It also gives the ability to handle process priority.
