Problems in installing Blitz 1.26

Hello Dan,

How are things?

After quite some time, I am back to Javaspaces. In my current
project, I am trying to create a PoC using Blitz; this time, with
your all-java version. When I tried to run 'blitz.sh', I was a little
perplexed by the outpourings on the screen. The background:

I installed Jini 2.1 afresh, on Redhat Linux Enterprise Desktop
version, which is equivalent to Fedora C 4. The hostname is 'cheetah',
though during installation, I supplied the name 'localhost' to avoid any
problems, kind of which I had faced during my earlier dabbles with
Jini and Javaspaces. This is a new machine, and almost everything
on the machine is configured by default, during installation.

Then I installed Blitz 1.26 using installer_pj_1_26.jar. At the time
of installation, I supplied 9000 as the port for HTTPD.

My JINI_HOME variable = /usr/local/bin/jini2_1
my JAVASPACES_HOME variable = /usr/nirmalya/blitz
[ To help you in visualizing the set-up and deciphering the portion of the
screen output, given below ]

No changes made to any of the config files or security settings (other
than jsk-policy.jar being copied to Java 1.4 'ext' directory during
Jini installation).

When I run blitz.sh, expecting a smooth run (and preparing to execute my
application), the following messages appear (cut/pased the first
few lines here, the rest comprising of exception stack traces):

When I tried to run Jini services alone (through Launch-All script
supplied with the installation), I got this:

================================  END ============================


My guess is that I am missing something very obvious, as
*-dl.jar are not found due the absence of HTTPD.

Could you please hint at the possible problem?

I know that questions of this category have been asked many times
over, in the mailing-list. Can someone direct me to the right
thread?

Many thanks in advance.
