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.
