Run NetBeans with JDK6, compile and run JavaEE app with JDK1.7

[Antonio Varela]

I've using NetBeans 7.1.2 with JDK7u5 on MacOS X from some time, and
as Mac users may have noticed, Apple's JDK has a overall better
integration with the OS than Oracle's JDK7 for OSX. What I'm trying to
accomplish is to run NetBeans with Apple's JDK6 and compile and run a
JavaEE app with Oracle's JDK7. I got this so far:

- Edit netbeans.conf and specify Apple's JDK6 as default jdk. Now
NetBeans gets launched with JDK6.
- In Tools -> Java Platforms added Oracle's JDK7 as a Java platform.
Now I have JDK 1.6 (Default) and JDK 1.7
- Created a new JavaEE6 app. In every project's properties (-ejb &
-war) I changed java plaform and source level to JDK 1.7
- Created a test JSF page with Java7 features, like diamond operators
and switch with string.

So far it's works fine, Java7 features are recognized. The problem
is when I try to run the application, Glassfish cames out with this
error:

"Error while trying to load Bean Class
com.icontech.jdk7test.indexBean :
java.lang.UnsupportedClassVersionError: WEB9032: Class
com.icontech.jdk7test.indexBean has unsupported major or minor version
numbers, which are greater than those found in the Java Runtime
Environment version 1.6.0_33"

wich oviously means that I need Glassfish to be started with JDK7.
I went to Glassfish server properties, and selected Oracle's java
executable but the server does not start:

"Error: This Java instance does not support a 32-bit JVM.
Please install the desired version."

well for starters, you always need to compile and run a project with the same version. Which you fixed by changing what version glassfish used

besides that, glassfish gave you your error. it seems you installed 32-bit java7
