Error in simple bean and JSP

I have not understood beans properly and i am getting an error 500 : Cannot find any information on property 'name' in a bean of type 'cool.Person'.
Please help me to rectify this.

The jsp

The bean

web.xml

On a quick inspection I can't see anything glaringly incorrect, but why are you using antiquated <jsp:getProperty> instead of the EL and JSTL?

What happens if you replace the getProperty tag with <c:out value="${dude.name}"/>?

(assuming you've enabled the JSTL)

A minor doubt? I may be missing something glaringly obvious. But where are you setting the bean?

The <jsp:useBean> tag will create a bean in request scope if one with that name is not already resident.

I agree Bear , but where are the initial values for the bean being set?

They aren't, unless it's happening in a controller that we do not know about. The property may be null, but that will not result in the error that is being seen.

Oh okies, Thanks for the info

I did not know it was outdated. :confused: Why should i avoid using getProperty ?
I am using the head first book (1.5) and making working code out of the snippets in the book. Not reached the JSTL part yet.

There is no error and i get a blank page. Why is that happening ? How to enable the JSTL ?

Thanks for telling me these new things. :)

Please tell me how to make this work.

Instructions on setting up the JSTL can be found in the JspFaq.
