I am running a Java 32-bit app on Mac OS X Leopard via Web Start. I need to make sure the VM loads in 32-bit mode. How can I do this in the JNLP?
I found the answer right after I posted. In the "resources" tag you can do a line like below. The "-d32" will force the 32-bit VM load:
<j2se version="1.5+" java-vm-args="-d32" href="http://java.sun.com/products/autodl/j2se"/>
