#2512 — Netbeans question?

I'm trying to learn how to use Netbeans but that isn't really my 
question.  When I start it I get a dialog that says "Invalid jdkhome", 
"Cannot locate Java installation", "C:/...1.7.0_10", "Do you want to try 
to use the default version?"  If I press the NO button it just quits, if 
I press the Yes button it starts and works normally.  I can't find any 
place in the program to change the "jdkhome".  It finds the current 
1.7.0_15 installation without any difficulty.  Anybody know how to reset 
this?

Thanks,

knute...

Look in Tools > Java Platforms; there should be an Add Platform button.

     I've seen this after installing a JDK update when NetBeans
is already present.  (Guess: The NetBeans installer sniffs out
an existing JDK, but the JDK installer doesn't detect and update
an existing NetBeans.) What works for me is to edit the file

	C:\Program Files\NetBeans<version>\etc\netbeans.conf

... and change the "netbeans_jdkhome=" line to point to my
updated JDK.

     (Um, er, you *do* have a JDK installed, right?)

I do :-)

I found the .conf file too and that does fix the dialog problem.

I followed John's advice (hint maybe) and added the existing Java to the 
platforms.  I discovered that the Default java installation does not 
have JavaFX for some reason but one can install the same java 
installation again (makes no sense to me).  But you can't delete the 
Default(?)

Thanks Eric and John

you are supposed to have a:

SET JAVA_HOME=E:\Program Files\java\jdk1.7.0_15

Perhaps it would have used that.

Seriously?

A zillion of them. It's the convention.

I do most of my development on Windows and it certainly isn't required 
to make the compiler or runtime function there.  I'm pretty sure I've 
never set it on my Linux box either.  From the link you posted I see 
that ant uses it but I don't see anything else except Glassfish.

That search gives links that also show that Maven, Eclipse, "Many Java applications" or "A lot of 
well behaving [sic] Java applications" (per a few of the links), JBoss, Macintosh, NetBeans, IBM Java, 
FreeBSD, Tomcat, the Android tools, shell scripts, and others use JAVA_HOME.

PEBKAC.

What does PEBKAC mean?  Have I been insulted?

Isn't jdkhome ultimately set by the $JDK_HOME environment variable 
if it's defined?

Or maybe it's just set by the netbeans.conf file. Here's mine, FWIW:

$ cat ${NETBEANS_HOME}/etc/netbeans.conf
#
netbeans_default_userdir="${DEFAULT_USERDIR_ROOT}/7.3beta2"
netbeans_default_cachedir="${DEFAULT_CACHEDIR_ROOT}/7.3beta2"

netbeans_jdkhome=/opt/java/java
netbeans_default_options="-J-Xms80m -J-Xmx640m -J-Xss2m -J-XX:PermSize=60m -J-XX:MaxPermSize=240m -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-ea -J-XX:+UseFastAccessorMethods -J-XX:+UseStringCache -J-XX:+OptimizeStringConcat -J-XX:+UseCompressedOops"

On my system "/opt/java/java" is a symlink to my default JDK_HOME.

I don't know.  Apparently I was using _10 when I installed NetBeans and 
it isn't smart enough to figure out the change.

So I changed the netbeans.conf file and I don't get the dialog any more.
