在linux 环境下且需要引入外部jar包时进行编译代码的命令范例：

javac -classpath /home/data/superhero/wang/myjlib/json-lib-2.4-jdk15.jar \ HanPengNewAndOldServerGoodsTypeSpendCoin.java

编译后运行java的命令范例为：

java -Djava.ext.dirs=/home/data/superhero/wang/myjlib HanPengNewAndOldServerGoodsTypeSpendCoin

注：  参数    -Djava.ext.dirs=/目录  只在 jdk 1.6版本之后的才可用。 其中   目录，如范例中 \ /home/data/superhero/wang/myjlib 为存放外部jar 包的地址。
