A big difference between Evergreen 1.2 and 1.4 is how it transports data  
over the network.  The OpenSRF 1.0/trunk (== Evergreen 1.4) Python client  
libraries cannot understand the JSON-encoded data produced by OpenSRF 0.9  
(== Evergreen 1.2).  However, there is a separate XML encoding OpenSRF  
supports that is consistent across versions.  To use Constrictor with a  
1.2 Evergreen server, you have to use "XML" for the evergreen.netProtocol  
property.

Attached is a sample constrictor.properties file that works on  
demo.gapines.org (Evergreen 1.2.4) and OpenSRF/Evergreen trunk Python  
client libraries.  No changes were made to any of the code.

To work with your server, you will need to change the evergreen.server and  
evergreen.workstation properties.  You may also need to change  
evergreen.username and evergreen.password, since my file uses the default  
admin.

Note that XML is bulkier than JSON, so requests as a whole may be a little  
slower.
