I followed this to point FlashBuilder 4 Beta 2 to Java 1.5 and it worked fine. This was so helpful. Thank you!

Actually, adding it to the .ini file is not enough.

You need to create a desktop shortcut(assuming Windows), and change your target like so:

“C:\Program Files\Adobe\Flex Builder 2\FlexBuilder.exe” -vm “C:\Program Files\Java\jre1.6.0\bin\javaw.exe”

How do I know?
I wanted to be sure…so after adding -vm to the .ini, I opened Process Explorer and checked the loaded files running under FlexBuilder.exe process. Sadly, my jre 1.6 wasn’t loaded.

It seems that -vm is ignored when they attach switches to the eclipse rcp executable.

If you do it my way, and you check process explorer, you will see that jre 1.6 is used.

HTH,
Steve

Thanks, this is a much cleaner way and most likely the preferred way of changing JVM’s.

An easier way to change the JVM used by Flash Builder 2 is to add the -vm switch to FlexBuilder.ini like this:

-vm c:\Program Files\Java\jre1.5.0_07\bin\javaw.exe

-vmargs -Xms128M -Xmx512M -XX:MinHeapFreeRatio=20
