Defining Java environment variables - getting Freeplane to work

I've been using Freemind for a while, thought I'd try it's fork, Freeplane.
http://sourceforge.net/projects/freeplane/
I'm on Debian Lenny. After some messing around, I got Java to go, verified at javatester.org.
But Freeplane does not fire up:

Code:

jeffm@jeffm-wks1:~/down/freeplane/freeplane-1.0.33$ ./freeplane.sh

ERROR:  Your Java is not a derivative from Sun's code,

        =======================================

        FREEMIND WILL MOST PROBABLY *NOT* WORK,

        =======================================

        define JAVACMD, JAVA_BINDIR, JAVA_HOME or PATH

        in order to point to such a VM.

        See the manpage of freeplane(1) for details.

I've tried messing around with things like 'export JAVA_HOME=/usr/bin/java' for the JAVACMD, JAVA_HOME and the other variables mentioned at the error, but no luck. I think I'm just messing up the export. Any ideas? Thanks for any help.

PS: I thought to read the freeplane manpage like the error said to, but there is none

is sun-java6-jre or sun-java5-jre installed? If not, install it.

Then, run

Code:

/usr/sbin/update-alternatives --config java

and select a Sun java.

Thanks for the reply. It is basically working now. Glad I didn't mess with export for too long, I was worried since a lot of the help I was finding via Google seemed to be 5=< years old...

Reading package lists... Done

Building dependency tree      

Reading state information... Done

sun-java6-jre is already the newest version.

The following packages were automatically installed and are no longer required:

  gs-esp libavahi-compat-libdnssd1 cups-client openssl-blacklist libslp1 ghostscript-x foomatic-db-engine avahi-utils

  cups-common ssl-cert cups cups-bsd foomatic-filters foomatic-db

Use 'apt-get autoremove' to remove them.

0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.

jeffm@jeffm-wks1:~$

So that was ok. Not sure why it wants to remove cups, but whatever.

There are 4 alternatives which provide `java'.



  Selection    Alternative

-----------------------------------------------

          1    /usr/bin/gij-4.3

 +        2    /usr/lib/jvm/java-gcj/jre/bin/java

*        3    /usr/bin/jamvm

          4    /usr/lib/jvm/java-6-sun/jre/bin/java



Press enter to keep the default[*], or type selection number: 4

Using '/usr/lib/jvm/java-6-sun/jre/bin/java' to provide 'java'.

3 is the default, 4 wound up doing the trick. There are a lot of Java-looking bugs in the app, that could be anything, at least it starts now. Thanks again for the help!
