You need to add an import statement so the JSP can find your Item class.
And of course the Item class needs to be found in your WEB-INF/classes directory or in a jar-file located in WEB-INF/lib

You should also place your bean in a package other than the default. Most servlet containers have problems with classes in the default package.
