I want to find a light http service for my Java program, and after research, I find nanohttpd is so light with only one java page, and easy installation, so I want to wrap my Java program with this framework.
I have tried tutorial on nanohttpd github page, everything is ok, but for the final step,
mvn exec:java -Dexec.mainClass="com.example.App"
it crashed after about 15seconds with this info
[root@zhangruichang-test-dev001-shgq myHellopApp]# mvn exec:java -
Dexec.mainClass="com.example.App"

Currently I have googled it but without any most related issues.
I use Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 21:51:28+0800) and OpenJDK with Java version: 1.7.0_85, vendor: Oracle Corporation on OS name: "linux", version: "2.6.32-573.1.1.el6.x86_64", arch: "amd64", family: "unix" with CentOS 6.4.
Could anyone help me?
