The following jsp page intends to print the name of the Account. Which of the given options accomplish this task correctly?
(The code for Account.java is given in exhibit. )

<html>
<body>
<h1>Simple Bean Usage</h1>
<%
com.enthuware.jwebplus.Account acct = new com.enthuware.jwebplus.Account(1, "Bob", 1000.0);
pageContext.setAttribute("account", acct);
%>

Account Name is : <<< INSERT CODE HERE >>>
</body>
</html>


This is from enthuware. In the answer's hint, it is written that this bean is already existing. How can i find in the quesiton that it say's that the bean is already there.

This is from ENhtuware.

Please advise.

When you create Bean object in the scriptlet, then it is accessible to that JSP.



Being "acct" bean is crated and already exists in the current JSP, you don't need to associate it with pageContext for using on the same page.

If you have other include files / helper classes for this JSP, then you will need to associate bean with pageContext to access other implicit objects from include files / helper classes.

As in the question, the bean is accessed on the same page, hence the hint is correct --> "bean is already existing"

Thanks,
