[Pellet-Users] Problem inferring hierarchy

[Goggles Paizano]

I'm new to Pellet and am having a bit of a problem integrating it with 
Protege 1.3. I am using the simply Pizza OWL ontology and would like to 
experiment with having a reasoner (pellet) infer additional hierachical 
relationships. I can successfully configure Protege to talk to my pellet 
server using the DIG interface capability. From within the Protege GUI I 
can also successfully verify and classify my ontology. However, when I 
try to 'infer a class hierarchy', my Protege session seems to hang at 
the point where it is sending a query to Pellet. The session output and 
error message in the pellet console is as follows:

 D:\bin\pellet-1.3-beta2>java -Xss4m -Xms30m -Xmx200m -classpath 
lib\pellet.jar
rg.mindswap.pellet.dig.PelletDIGServer

PelletDIGServer started (Port: 8081)
ERROR [SocketListener0-0] (DIGTellHandler.java:251) - Ignoring invalid 
tell com
and:
<?xml version="1.0" encoding="UTF-8"?>
<equalr>
    <ratom name="isIngredientOf"/>
    <inverse>
        <ratom name="hasIngredient"/>
    </inverse>
</equalr>


Any insight into what the problem may be would be much appreciated. Thanks
