Working through "easing gently into opensrf", I can't seem to invoke my method via srfsh

# Installed OpenSRF 1.6.1 (w/ --enable-python) per: 
#   http://www.open-ils.org/dokuwiki/doku.php?id=opensrf:1.6:install
# following each step 

# Can make requests to opensrf.math service via srfsh, so:
#   * services ought to be installed and running properly
#   * srfsh.xml ought to be ok

# Tried to work through Easing Gently into OpenSRF, Part 1:
#   http://journal.code4lib.org/articles/3284
# ... but am doing so in Python, so I know I've got something wrong

# Added opensrf.test service to public router in opensrf_core.xml

# Not sure at all that what I put in opensrf.xml is linked to the code I wrote.  
# Suspect error in "implementation" element above?

now I see updates to this - good to see that jeff and I basically share a brain. Asides:

• I was running on Fedora 13, OpenSRF trunk, Python 2.6.4
  • Didn't have any problems with comments in opensrf.xml
  • Didn't have any problems running opensrf.py in daemonize mode

Might just be a distro thing? I blame Canonical. Otherwise, yay!

Thanks a bunch, y'all. Combined your suggestions and got it working. Btw, I did have problems with comments in opensrf.py, and but did not have problems with daemon mode (though I used start_all instead of the -s flag).
