[kepler-users] Globus jobs/Grid FTP on Kepler

[Matthew Jones]

Hi,

The globus actors have to be used in a particular sequence, which is 
demonstrated in the test workflow 
"workflows/test/nmiworkflow-example.xml".  This file is only available 
in the development version of Kepler, not in the beta releases. (You can 
also get it fro the web here:
http://cvs.ecoinformatics.org/cvs/cvsweb.cgi/~checkout~/kepler/workflows/test/nmiworkflow-example.xml?content-type=text/plain 


If you open that file, you'll see that the Globus proxy actor is 
connected to the globus job actor and the grid ftp actor (and provides 
the proxy credentials).  You have to configure the proxy actor to 
provide your proxy certificate information, which has to be locally 
available on the local host (in the configuraiton dialog, it asks you to 
browse to your cert files).  The proxy actor output is connected to the 
input string of the globus actor (providing the proxy certificate).

One caveat is that I am not sure if these actors are working at all. 
There are new versions of the globus libraries and I'm not sure what 
version is being used here -- if it works for you I'd really like to 
know about it.  Thanks.

Matt
