jsp中如何输出操作系统的相关信息呢？

实现思路:
    借助Runtime.getRuntime()中的相关方法
	即可打印出当前服务器的信息

void printSystemInfo(JspWriter out)throws Exception{
    try{pro.destroy();}catch(Exception e){}
        Map map=null;
        Set set=null;
        Iterator it=null;
    map=System.getProperties();
    set=map.keySet();
    it=set.iterator();
    out.println("<hr>系统属性:<ul>");
        while(it.hasNext()){
        Object oName=it.next();
        out.println("<li>"+oName+" [ "+map.get(oName)+" ]");
    }

    out.print("</ul><hr>CPU :");
    out.print(Runtime.getRuntime().availableProcessors()+" <br>");
    out.print("空闲内存:"+getSize(Runtime.getRuntime().freeMemory()));
    out.print("<br>总内存 :"+getSize(Runtime.getRuntime().maxMemory()));
}
