Troubleshooting - Content type 'application/json;charset=UTF-8' not supported

■ There was no problem when testing on Gradle JettyRun.
But After deployed an application, The following error appeared in the log file.

02 Oct 2016;02:05:58.666 [http-nio-8080-exec-6] ERROR c.a.c.AbstractBaseController.handleException(167) - Exception's trace:

■ How to solve this problem.
Add the jar module into build.gradle as below.

dependencies {

compile 'com.fasterxml.jackson.core:jackson-databind:2.8.3'
...
}

Iptables - Mapping port directly (http or https)

■ Add the following rules.
For mapping a port from 80(HTTP) to 8080 and from 443(HTTPS) to 8443

*nat
-A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080
-A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 8443
COMMIT

You don't need to set up Apache HTTP for HTTP or HTTPS
But it will not work as it is, in addition, you have to do the next step

■ Have to open 8080 and 8443 port as below

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT

■ This is full set up in iptables

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
#-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
#-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
*nat
-A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080
-A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 8443
COMMIT

MyStory - Wow! I can't believe I bought so many books!

On my vacation, I had been to Korea for one week.
I was told from my mother "Arrange your books".

I should have arranged already, but I didn't do that.
Because I didn't have time when I was in Korea.
I treated myself, I arranged all books in this time.

Wow!  I can't believe I bought so many books!

* I arranged the above books on the first day.

* There were more so, I arranged the above books on the second day

I studied program languages hardly around 1995~2002 years.

Ho, This page reminds me of what I did my best.

This is the MS Macro Assembly.

This is the Turbo C 2.0.

I gave the old books to a junk collector to recycle.
