I have made what I'd like to call some progress, but the connection still hangs.

I installed the jdbc Postgres driver (postgresql-9.3-1102.jdbc4.jar) from http://jdbc.postgresql.org/download.html.

Modified the run BAT script to :

SET H2DRIVERS= -pg -tool
SET CLASSPATH=-cp "D:\Program Files (x86)\H2\bin\h2-1.3.175.jar
SET CLASSPATH=%CLASSPATH%;D:\some_path\postgresql-9.3-1102.jdbc4.jar"
SET H2FLAGS= -webAllowOthers -tcpAllowOthers -url jdbc:h2:file:AvCloud
+LiteDB -driver org.postgresql.Driver

java  %CLASSPATH% org.h2.tools.Console %H2DRIVERS% %H2FLAGS%

This brings up the h2 server, and apparently listens on some random port. I find the port using "netstat-an".

Then try to run this perl - which now hangs.:

use strict;
use warnings;
use DBI;

my $dbh = DBI->connect("dbi:Pg:dbname=AvCloudLiteDB;host=127.0.0.1;por
+t=60077;",
                      ,, #$username,      $password,
                      {AutoCommit => 0, RaiseError => 1, PrintError =>
+ 1}
                     )
  or die "Cannot  - db:$DBI::errstr";
print "Connected..\n";
my  $sth = $dbh->prepare("SELECT * from GRIDS");

while (my $h = $sth->fetchrow_hashref){
   print "$_=$h->{$_}; " for keys %$h;
   print "\n";
}
close $dbh;
