[Hps-ecal] HPS software on CLON machines

[Andrea Celentano]

Dear all,
during the HPS commissioning and data taking runs, we need to use the 
HPS-software to monitor the ECAL (and probably the SVT too).

This requires to install the hps sofware on the clon machines.

There're different ways to do this, and some pre-requirements. I try to 
list them here, to discuss with you how to proceed. I'll not do any 
change on any configuration before we have a clear plan.

1) Java.

HPS needs Java 1.7 (at least). I've seen that on some clon machines we 
have java 1.7 (clonpc11, clonpc1), while on others we have java 1.6 
(clondaq3)

I see that, to by-pass this problem, the .cshrc of the hpsrun account 
was modified with:

setenv PATH /misc/home/rafopar/Apps/Java/jdk1.7.0_67/bin:${PATH}:

- Do we need to install java 1.7 on all clone machines? If so, I suggest 
to have it in some "common" folder that is seen by all clones (or, at 
least, by the machines that we expect to run the monitoring software on)

2) HPS-Software

We can proceed in two ways:
- Install only the compiled jar file
- Install the source code and compile it

Probably, since we need only the monitoring application, we can proceed 
with the first option. To proceed with the second, we need:
-- Access to the svn repository from the clon machines 
(svn://svn.freehep.org/hps)
-- maven installed on the clon machines

Thanks for your feedback
