Using bean in JSP files
-------- Mensagem Original --------
Assunto: Using bean is JSP files

Hi all,
Is there any difference between the following code in order to
use bean?
<%@ page import="java.sql.*"%>
<jsp:useBean id="connection" class="br.fua.ppgi.ConnectionBean"
scope="session"/>
<%@ page import="java.sql.*,br.fua.ppgi.*"%>
<jsp:useBean id="connection" class="ConnectionBean" scope="session"/>
The former code (I followed the core servlets and JSP
book's idea) is doing well , but the latter code (I followed the Web
Development with JavaServer Pages book's idea) shows me an error on the
browser as:
javax.servlet.ServletException: ConnectionBean
....
....
root cause
java.lang.InstantiationException: ConnectionBean
....
....
Could anyone help me?
Regards,
Lin.

The JSP 1.2 specification actually states that the class attribute should contain
the fully qualified name of the class. To quote:
The fully qualified name of the class that defines the
implementation of the object. The class name is case
sensitive.
