Paranj, You can create your own abstract class which provides the method(s) declaration(s) that is/are common to all your subsequent concrete classes, but which have no implementation code. You would then use your abstract class via inheritance to create your concrete classes, each of which implement their "shared" or "common" methods differently. You can create instances of these concrete classes that are inherited from your abstract class, so you can use them as beans in your JSP. Just remember, a Java bean by it's definition can take no parameters as part of it's constructor, where as a Java class can.
Just as in C++, you cannot instantiate an abstract class, so if your question pertains to whether you can create an abstract Java class and use an instantiation of it as a bean in your JSP page, the answer is no. By its very nature, an abstract class has as least one method that has no implementation code.

There are two business functions which share some methods and they differ in other methods. So, can I use abstract bean in this case ? I am calling the concrete beans from a JSP page.
