Yes, your colleague is correct. If only the AJP connector is configured you can’t access Apache Tomcat with your Browser. Your Browser speaks HTTP and not AJP. Thinks would be different if there is an HTTP-Connector configured. > > I am not technically aware of this AJP configuration and constraint, so > that's why I want to make sure if the above condition stated by the team > member is indeed correct. May be he lacks or unaware of any other alternate. Not judging your colleague here and what is reasoning is. Sysadmins usually place Tomcat behind an Apache because: * Load balancing * Routing many services within a single website * SSL issues * SLA or corporate policies * Trust We have been running standalone Apache Tomcat since version 6. It is stable and has not caused any troubles in all these years.
