Hi, basic question on AbstractPortalComponent

In a Portal Application i create a AbstractPortalComponent,

who can tell me how to change the page title .(the page default title is 'SAP Enterprise Portal 6.0')

the AbstractPortalComponent source code is :

import com.sapportals.portal.prt.component.*;

public class MyIndexComponent extends AbstractPortalComponent

{

public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)

{

response.write("this is my first AbstractPortalComponent");

}

}

Thanks so much your your response!
