How to make 64-bit JVM the default on Solaris 10

Hi,

I am running my application on a 64-bit Solaris 10 machine. Currently, my application uses JRE 1.6 32-bit version. I am trying to make it work with JRE 1.6 64-bit version. I successfully installed 64-bit java using the instructions here: How do I install Java for my Solaris x64 computer ? - 1.5.0 and am able to invoke 64-bit java using either

Code:

$JAVA_HOME/bin/java -d64

or by using

Code:

$JAVA_HOME/bin/sparcv9/java

My application always invokes the java executable under $JAVA_HOME/bin. By default, this is invoking the java 32-bit version which I do not want. Of course, I could add the -d64 option to all calls to java in my application. However, I do not want to do that as java is being called from a number of scripts and some scripts are also being shared between multiple platforms.

How do I make the 64-bit java the default? I tried copying over the java executable from under $JAVA_HOME/bin/sparcv9 to $JAVA_HOME/bin. This seems to invokes the java 64-bit version correctly from within my application. However I do not know if this is the right thing to do or if it has adverse side effects.

Any help/inputs will be greatly appreciated!

Thank you so much.

AIRPORT2-PORTINSPECTOR(1)				      General Commands Manual					 AIRPORT2-PORTINSPECTOR(1)

NAME

       airport2-portinspector - Port maps inspector for the Apple AirPort Extreme Base Station ("Snow")

SYNOPSIS

       airport2-portinspector

DESCRIPTION

       airport2-portinspector allows you to inspect the port maps used by the hosts associated with your base station.

OPTIONS

       airport2-portinspector  accepts	no  command-line options. airport2-portinspector is a wrapper script around the PortInspector.jar jar file
       located in /usr/share/java/airport-utils.

       You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG  environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The  full  path  to  the	Java  Virtual  Machine	to  use.  By  default,	the  wrapper  uses JAVACMD; if it is not set, it looks for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
