Running java in 32 bit mode on windows 64

According to this FAQ :

How do I select between 32 and 64-bit operation? What's the default?

The options -d32 and -d64 have been added to the Java launcher to specify whether the program is to be run in a 32 or 64-bit environment. On Solaris these correspond to the ILP32 and LP64 data models, respectively. Since Solaris has both a 32 and 64-bit J2SE implementation contained within the same installation of Java, you can specify either version. If neither -d32 nor -d64 is specified, the default is to run in a 32-bit environment. Other Java commands (javac, javadoc, etc.) will rarely need to be executed in a 64-bit environment. However, the -d32/-d64 options may be passed to these commands and then on to the Java launcher using the established -J prefix option (eg: -J-d64).
All other platforms (Windows and Linux) contain separate 32 and 64-bit installation packages. If both packages are installed on a system, you select one or the other by adding the appropriate "bin" directory to your path. For consistency, the Java implementations on Linux accept the -d64 option.

I've found another solution to that. By using launchj4 I can wrap my jar into an exe and I can specify the JRE I want to use and force it to search for a 32bit JVM, set min and max version etc (see the JRE). The wrapper will automatically search installed JRE's and chose the one that meets the requirements.

Also wrapping my jar into an exe is more convenient for deploying my application.
