We have developed an agent (SIF UK 1.2 standards) which is tested against the Edustructres' ZIS. During the course of integration with our client's ZIS server, we experienced some issues related to Version mismatch between the Agent and the ZIS server. 

First attempt was made with following version setup in the code - 
ADK.initialize( SIFVersion.LATEST, SIFDTD.SDO_LEARNER); 

The reply was 

DEBUG [ADK] SIF_Ack Does NOT support version: 2.3 Earliest: 2.0 Latest : 2.2 
DEBUG [ADK.Agent$Connectathon5] Receive SIF_Ack (Status = none; Errors = 1) 
DEBUG [ADK.Agent$Connectathon5] [Category=1; Code=1] XML format error or SIF Message format error: Could not retreive SIF_Message, SIF_Header or SIF_SourceId XML elements 



Second attempt with - 
ADK.initialize( SIFVersion.SIF22, SIFDTD.SDO_LEARNER); 

SIF packet sent:

Our client's suggestion to fix this is 
"The zone you’re connecting to currently only supports UK 1.0 (Infra 2.0r1), UK 1.1 (Infra 2.1) or UK 1.2 (Infra 2.3) so you’ll need to remove: 
<SIF_Version>2.2</SIF_Version> 
<SIF_Version>1.1</SIF_Version> 
<SIF_Version>1.5r1</SIF_Version> 
<SIF_Version>2.0</SIF_Version> 
From your message." 



I am trying to use following code, as instructed in the documentation 

AgentProperties props = zone.getProperties();
props.setZisVersion("2.1"); 

But it is still sending multiple SIF_Version elements, whereas the documentation (page 41) says that there would only be a single SIF_Version element. 


How do I fix this issue?
