Hi again, I modified the <context> element in the $CATALINA_HOME/conf/context.xml to <Context className="org.apache.catalina.ha.context.ReplicatedContext"> and removed the <Context element from <Host> element in the $CATALINA_HOME/conf/server.xml file, and now it's not throwing any error.
But I still can't retrive from a one instance the attributes set in ServletContext in another instance. Any suggestions?
