I've spent all afternoon trying to Google an answer to this, but my
brain hasn't come up with the right search terms :-)

I have a Java application which is built with Maven 2. The application
includes a 32 bit native library. I work on Mac OS X 10.5.7 using
NetBeans 6.5.

This week I installed the latest Java update from Apple and NetBeans
wouldn't create new classes etc. (as mentioned in other posts) so I
told NetBeans to run under JDK 1.6, which it now does. Unfortunately,
JDK 1.6 on the Mac is only 64 bit, and NetBeans now starts Maven with
JDK 1.6, which means that when I try to run my application, JDK 1.6 is
used. This obviously has disastrous consequences when I get to the bit
where my 32 bit native library is called.

All my POMs contain source=1.5 and target=1.5, but this has no effect
on the JDK/JRE used when executing the app. My Java preferences and my
JAVA_HOME all point to JDK 1.5, which runs in 32 bit mode, but
NetBeans overrides this when calling Maven.

Can anyone tell me how to get NetBeans to tell Maven (or the app) to
run under JDK 1.5?

in 6.7 you can set the JDK to be used by the maven build (among other
things) in the Build/Compile panel in the project properties dialog.
in 6.5 you can (if I recall correctly) set the Env.JAVA_HOME property in
the Actions panel in project properties for the Run/Debug project action
mapping.

There might be more cards in the game as Mac has a weird way of defining
env variables. The programs executed from UI get different set than
program run from command line..

Thanks, Milos. The 6.7 way works for me, and it's probably about time for me to upgrade anyway.

I'd love to upgrade, but our apps run on IBM websphere and the plug-in for WAS is busted after 6.5.1
