Running an Eclipse application on Snow Leopard

Today I was trying to run the Eclipse RCP "Hello World" application with a view on my Mac. I was getting the following stack trace when trying to run the app:

java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM

I turns out that the Eclipse SWT libraries will not run with a 64 bit jvm. I came across this blog which explained how to fix. The short and sweet answer is to add the -d32 as a vm arg in the run configuration.
