How to specify to the Java VM the -d32 parameter

I recently downloaded watij. on their website they say

Note: If you are running on a Mac you mu开发者_如何学Pythonst add -d32 to your Java VM parameters.

I was wondering what the steps are to do this since they do not specify.

adding -d32 to vm parameters means, when you run your app:

javac HelloWorld.java
java HelloWorld

Instead you do this:

javac HelloWorld.java
java -d32 HelloWorld

It specifies that the program will run in 32bit architecture.

To set JVM arguments from Eclipse, do this:
1. Right click on the class you want to run.
2. Click run configurations
3. Go to arguments tab and write "-d32" under VM arguments text box.
