Using Beans And Session Scope

The scope in which the Bean exists and the variable named in id is available. The  default value of scope is page. We use the scope attribute to specify additional places where bean is stored. 

session: In this the bean will get stored in the HttpSession object associated with the current session.

In this example we are making one bean class inside which we are declaring one variable counter of type int. Inside this class declare one setter and getter method. Now make one jsp page inside which declare one standard tag <jsp:useBean> which is used to build the object of the bean class. To set the the value of the setter method of the bean class in the jsp use a scriptlet directive. Inside this directive call the setCounter() defined in the bean class by the reference of the bean class. At last to get the value which we have set in the setter method call the method getCounter() defined in the bean class by the reference of the bean class. This method will return how many times the page has been visited in the current session. 

The code of the program is given below:

package Mybean;

public class UsingBeanScopeSession{
  private int counter = 0;
  public void setCounter(int counter){
    this.counter = counter;
  }
  public int getCounter(){
    return counter;
  }
}

The output of the program is given below:
