how to call java method using quartz2

hi .actually i need to call java method on future specific time. and i am
using cron pattern for creating the time but i am not getting how to call
the my java method 

This is my simple code which invoke the method

	CamelContext context = new DefaultCamelContext();
		context.addRoutes(new RouteBuilder() {
		    public void configure() {
		    	from("quartz2://myGroup/myfirstrigger?cron=0/2+*+*+*+*+?").to(new
Schedule().show());
		    	
		    }
		});
		context.start();
 
   the show() method available inside the schedule class so how to call. i
do not have any idea.

	}

	public static void main(String args[])throws Exception
	{
		JndiContext context1 = new JndiContext();
		context1.bind("bye", SayService("Good Bye!"));
		
		
		CamelContext context = new DefaultCamelContext(context1);
		context.addRoutes(new RouteBuilder() {
		    public void configure() {
		    	
		    
from("quartz2://myGroup/myTimerName?cron=0+0/3+12-18+?+*+MON-FRI").to("bean:bye");
