Re: [las_users] a fresh new LAS not plotting COADS!

Emanuele,

The complaint from LAS is that it cannot find your product server URL.

I suspect that you have not yet added the required changes to your Apache configuration so that the las-bin directory is properly aliased to your LAS installation. Instructions for what to do appear at the end of the configure process.

When the script alias is set correctly you should be able to put the "http://colore.ifa.rm.cnr.it/las-bin/LASserver.pl?xml=..."; into your browser and get a plot.

Dear LAS-ists,

I've just made a fresh new LAS installation on my Linux machine and it
works properly UNTIL the moment I ask to plot!

LAS configuration had no problem and I set the server up use the sample
COADS climatology and Levitus climatology datasets that are distributed with LAS.

I can manually plot them via Ferret, but I have errors when I try to
plot them using LAS.
On the browser I succesfully go up to the CONSTRAINTS page http://localhost:8080/las/servlets/constrain?var=2 Datasets > COADS climatology Variable(s): AIR TEMPERATURE
and when I click the red "Next >" I get a new window with the following
error:

There are so many other messages (as usual in Java!)
My installation is:
java/jdk1.5.0_05
LAS 6_5_1_2
tomcat is the one coming with LAS (5.5.9)
I notice that /server/log dir is empty and also noticed some strange (to
me) lines in the file server/Ferret_config.pl which contents are the
following:

sub ferret_config_init {
my $config = shift;
my $which_ferret = "/usr/local/ferret/bin/ferret";
my $ferret_args = "-gif -server";
my $ferret_ps_args = "-server -batch";
my $ferret_transcript = "log/debug_ferret.jnl";

$config->{which_ferret} = $which_ferret;
$config->{ferret_args} = $ferret_args;
$config->{ferret_ps_args} = $ferret_ps_args;
$config->{ferret_transcript} = $ferret_transcript;
}
$ENV{FER_DIR} = ". /usr/local/ferret";
$ENV{FER_DESCR} = "des . . /usr/local/ferret/descr";
$ENV{FER_DATA} = "./data . . /usr/local/ferret/data /usr/local/ferret/go /usr/local/ferret/examples /usr/local/ferret/contrib";
$ENV{FER_GRIDS} = ". . /usr/local/ferret/grids";
$ENV{FER_PALETTE} = "custom jnls jnls/insitu jnls/section . . /usr/local/ferret/ppl";
$ENV{FER_GO} = "custom jnls jnls/insitu jnls/section . . /usr/local/ferret/go /usr/local/ferret/examples /usr/local/ferret/contrib";
$ENV{PLOTFONTS} = "/usr/local/ferret/ppl/fonts";
$ENV{FER_EXTERNAL_FUNCTIONS} = ". /usr/local/ferret/ext_func/libs";
$ENV{DODS_CONF} = "dods/.dodsrc";
1;

What's strange (to me) is the last line (1;) and the values of:

$ENV{FER_DESCR}
ENV{FER_GRIDS} $ENV{FER_GO}

Can you help me, please?
Thank you from Italy,
Emanuele Lombardi
