the release notes say;
Installation issues
Following procedure/adjustment is mandatory if You install at CentOS6 (64bit) or ORACLE Linux 6 (x86)
If port 80 is not set in ip tables. Tomcat will not work at all - scaly-tomcat service will run, but in tomcat log there will be a big backtrace msg.
Add port 80 iptables afterward
restart iptables service
restart scaly-tomcat service
restart httpd serviced
and after all this, it finally works(even Oracle Linux 6 x86)
By this do you mean you require port 80 to be permitted (inbound/outbound?) in iptables?
