Hi,
I am trying to set up load balancing and clustering, but whenever I put
in a request to the lb server I get:
java.lang.IllegalArgumentException: Required property
"mcastClusterDomain" is missing.

I've looked at source code and config, and this property is always set!
My server.xml files look like this:
<Server port="8005"
shutdown="SHUTDOWN" >
<GlobalNamingResources>
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and
saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>
<Service name="Catalina">
<Connector port="8009"
enableLookups="false"
redirectPort="8443"
debug="0"
protocol="AJP/1.3"/>
<Connector port="8080"

maxSpareThreads="75"

</Cluster>
<Host name="localhost"

</Engine>
</Service>
</Server>
Has anyone cracked this error please? I have tried with 5.5-17 and
5.5-25 tomcats, same issue.
