configuring ajp13 worker on tomcat 3.2.3

[David Lee]

hi,

i'm using nsapi to configure iPlanet with Tomcat 3.2.3.  they're 
communicating via the ajp13 worker.  the workers.properties file on the 
iPlanet box is configured to setup ajp13, and i know the server.xml file on 
the Tomcat box needs a tag for an ajp13 socket.  i have it setup as follows:

<Connector classname="org.apache.tomcat.service.PoolTcpConnector">
            <Parameter name="handler" 
value="org.apache.tomcat.service.connector.Ajp13ConnectionHandler"/>
            <Parameter name="port" value="8443"/>
            <Parameter name="max_threads" value="200"/>
            <Parameter name="max_spare_threads" value="100"/>
            <Parameter name="min_spare_threads" value="10"/>
</Connector>

when i start the server up, i get an xml parser error:

At Line 269 /Server/ContextManager/Connector/ 
classname=org.apache.tomcat.service.PoolTcpConnector

any help would be greatly appreciated.  i apologize in advance if this is a 
silly question.

thanks,
dave
