OK.  I removed jre and installed jdk.  This allowed me to install the 
java-sun-compat from jpackage.org, but now....

java -version

gets command not found.  I THINK in part this might be due to the 
Alternatives commands I entered?  I HAVE NOT been able to trace through 
all the links.  It seems to be a mess!

And of course, although I finally got freemind installed (all sorts of 
things needed from jpackage for that), it won't run without finding java.
