Java - Common Daemon in Java

@Download Commons Daemon
$ wget http://ftp.meisei-u.ac.jp/mirror/apache/dist//commons/daemon/source/commons-daemon-1.0.15-src.tar.gz
@Decompress
$ tar xvf ./commons-daemon-1.0.15-src.tar.gz
@Change Directory
$ cd /usr/local/src/commons-daemon-1.0.15-src/src/native/unix
@You need to build the "configure" program with:
$ ./support/buildconf.sh
@Set configuration and compile
$ ./configure --with-java=/usr/local/java
$ make
@Move jsvc to home of apps
$ mv /usr/local/src/commons-daemon-1.0.15-src/src/native/unix/jsvc /usr/local/app/
