How to Execute Codes When Press Finish In CDT New Wizard

I have created a new wizard by extending the MBSCustomPage class, I was wondering how can I execute some codes when finish button has been pressed,
I have implemented the Runnable and I had written the codes in run method,
This was not adequate for going to run method after pressing finish,
I had to add my class to operationClass in MANIFEST as well.


Here is the code which is needed.
public class NewProjectWizardPage extends MBSCustomPage implements Runnable{
/**
*This is called when the finish button of the new Project Wizard has been pressed
*/
public void run(){

}
