ActiveMQ 和Commons-Daemon整合

??????????? 在一般的java项目中，如果在linux中实现进程在后台执行比较简单，可以采用nohup cmd 或者sh cmd &等多种方式实现，进行在后台执行。但是在window操作系统中就比较困难了，需要实现相关的类。如在tomcat，jboss的启动之后，端口一直开放着。

????????? 常用实现方式实现Commons-Daemon中的Daemon接口实现相关的方式，使用相关的bat，命令启动。在Commons-Deamon调用jsvc实现。

?

在activemq.bat中相关bat命令如下：

备注：在run.jar包中Main方法调用?ActiveMQLauncher 实现相关的功能。

?Daemon that implements the following methods: 
void init(String[] arguments): Here open configuration files, create a trace file, create ServerSockets, Threads void start(): Start the Thread, accept incoming connections void stop(): Inform the Thread to terminate the run(), close the ServerSockets void destroy(): Destroy any object created in init()
