<jsp:useBean id="employee" class="com.examulator.Person" scope="page" />
<!-- Your Code --> <c :-o	 ut value="${employee.firstName}" />

will the below code is correct to print the "marcus" as ouput?

<c:set target="${employee}" property="firstName" value="marcus"/>

[Sunny Jain]

I think, It should..!

[Amruth Puppala]

yes it is correct

[deepa raj]

target value should be bean Object or Map object right ?

[Sunny Jain]

yeah, you can see that employee is a bean object

[deepa raj]

hi sunny,

in HFSJ 2nd edition , Chapter 9 -page no 456 says , "Don�t put the �id� name of the attribute here! "

can you please explain this.

[Marcus Green]

deepa raj, what happened when you compiled the code?

[Milind Patil]

I tried this code, it prints "marcus" as ouput.

About in HFSJ 2nd edition, Chapter 9 -page no 456 says , "Don�t put the �id� name of the attribute here! "

This means that don't use "id" name as a target directly. Instead use "id" name in a EL expression.

Use like this:
<c:set target="${employee}" property="firstName" value="marcus"/>

Don't Use like this:
<c:set target="employee" property="firstName" value="marcus"/>
This will throw ServletException...
