Hmm.  I have Ubuntu with JGR 1.7, and i don't see any of those messages.

I see only:
> library(JGR)
Loading required package: rJava
Loading required package: JavaGD
Loading required package: iplots

Please use the corresponding JGR launcher to start JGR.
Run JGR() for details. You can also use JGR(update=TRUE) to update JGR.
> JGR()
Please consider running JGR() as root to create a start script in
/home/pauljohn/R/i486-pc-linux-gnu-library/2.10/JGR/scripts/run
automatically.
Starting JGR ...
Warning message:
In file(con, "w") :
  cannot open file
'/home/pauljohn/R/i486-pc-linux-gnu-library/2.10/JGR/scripts/run':
Permission denied

I need to track down that "Permission denied" in my home directory,
but JGR still seems to run. I can load datasets, do ordinary stuff.

What commands do you run to make the bad things happen.?


I wonder if you have more than one java development environment
installed.  It could be you have openjdk, which is the default, as
well as the Sun packages.  I suppose if your /etc/alternatives links
are not proper, it could confuse a lot of things.

The only *flashing warning* thing I noted about your post that might
be a sign of trouble is this comment:

"I'm using sun-java6 (jre and jdk)."

If you install the Sun JDK, it includes the JRE within it, and
installing both the jdk and the jre could cause the problem you see.
If R CMD javareconf finds the JRE (which you installed separately from
the JDK), then it has runtime stuff but no access to the devel
libraries.
