Hi Eric, I was also getting the same error , when checked through netstat -tulpn I noticed that port 8080 is used by Oracle listener , as default port for tomcat is also 8080, I was facing similar issue. After manually changing port for tomcat in server.xml t and restarting rhn-satellite worked for me..
