I am a newbie and these details are a world for me. Thanks 
to Skip and Peter for being patient with my ignorance.

After checking "netstat -an", as suggested, there is NO 
entry for anythig listening at port 2002. Either OpenOffice 
is running or not.

Now the main question is how to access OpenOffice from 
Python. Why PyUNO fails with the error:

c:\Archivos de programa\OpenOffice.org1.1\program>python 
swriter.py
Traceback (most recent call last):
   File "swriter.py", line 27, in ?
     smgr = resolver.resolve( 
"uno:socket,host=localhost,port=2002;urp;StarOffice
.ServiceManager" )
__main__.com.sun.star.connection.NoConnectException: 
Connector : couldn't connec
t to socket (WSAECONNREFUSED, Connection refused)

The swriter.py script should start a new OpenOffice 
instance, so I do not really understand what should be 
listening at :2002.

What do I need to setup to get the PyUNO connection working?
(I have appended the offending Python code at the end of the 
message)

Is there a way to access OpenOffice through COM? (I have 
used COM to automate MS-Office). Is there a COM object 
map/tutorial for OpenOffice?

Thanks in advance

Enrique

ships with PyUNO

     cursor = tableText.createTextCursor()
     cursor.setPropertyValue( "CharColor", color )
     tableText.setString( text )

localContext = uno.getComponentContext()

				"com.sun.star.bridge.UnoUrlResolver", localContext )

smgr = resolver.resolve( 
"uno:socket,host=localhost,port=2002;urp;StarOffice.ServiceManager" 
)   <--------- This is the offending line.
remoteContext = smgr.getPropertyValue( "DefaultContext" )
