Quartz NotSerializableException Exception

Im using quartz 1.5.2 with spring 3.0.5 version. When i try to get the scheduler context with jdbc store type quartz, im facing NotSerializableException. I have done my research to get it done but i couldnt managed to get over it. Im out of ideas.

Here is the scheduler configuration.

Use inner classes. No serialization is required. http://shyarmal.blogspot.com/2011/07/quartz-20-schedule-cron-with-spring.html

EmailSenderJob and all of its members need to implement Serializable.
