Installed: the Apache server sits on the 80th port and requests *.jsp redirects via mod_jk to Tomcat, which is 8080. And everything works fine, but the question is, what about port 8080 on which Tomcat is spinning? After all, anyone can instead example.com to gain example.com:8080 and thus bypass the Apach! I mean a deliberate action of the user.
Just change the port to some other I think not an option.
