What are you using for a client?  You built one from the IBM article 
w/ apache axis?

This should be

WEB_ROOT_DIR = $(RELEASE_DIR)/web

So if you are going through a firewall and only port 9618 is 
available, that means all your SOAP client can speak to the 
condor_collector.  That means a soap client can make collector 
queries, aka similar sorts of things that the condor_status tool does.

If you want to query about jobs (aka like condor_q), you need to 
communicate with the schedd.  That will listen on a different port 
--- by default, a dynamic one.  If you have to traverse a firewall, 
you will probably want to tell Condor to run the schedd on a 
well-known port and tell your firewall about that port as well.  If 
you want to submit/remove jobs (aka like condor_submit, condor_rm), 
then you need even one more step than the IBM article discusses --- 
you need to either run SOAP over HTTPS (i.e. with a client side SSL 
certificate) so Condor can authenticate the client, or you need to 
explicitly tell Condor to trust anyone who knocks at the door via 
placing into condor_config:
    QUEUE_ALL_USERS_TRUSTED = True
[[ Note: I would not recommend doing this on the public internet, esp 
if you leave ALLOW_SOAP=* !!!]

We are currently in the process of writing up some decent 
documentation for the Condor Manual on all things SOAP related.  It 
should help out a lot.  Sorry it is not already there....  but it is coming.

Todd
