Hi
I was browsing through the archives and found your example with frames very
helpful.
I am following the Servlet -> JSP architechture. So, all the requests come
to my servlet, the servlet makes computation and sends results to the JSP
in a bean.
For the login command, I need to display the user's home page with frames,
if login was successful. The LoginServlet authenticates the user and gets
the data needed for home page and passes it over to MAIN.JSP, which uses
three frames. MAIN.JSP does not itself use the bean, but one of its frames
(HOME.JSP) uses it.
LoginServlet.java
-----------------
ResultBean rb = new ResultBean();
rb.setXXX(..);
rb.setYYY(..);
req.setAttribute("resultBean", rb);
getServletContext().getRequestDispatcher("/jsp/main.jsp").forward(req, rep);
MAIN.JSP
--------
<frameset rows="79,*,20" scrolling="no" ....
<frame src="/jsp/home.jsp" name="main" ...
HOME.JSP
--------
<jsp:useBean
id="resultBean"
scope="session"
class="com.vitaltone.servlet.ResultBean"
/>
<b>Result : </b>
<jsp:getProperty
name="resultBean"
property="result"
/>
To my surprise, resultBean instance was null in HOME.JSP. What might be the
problem?
Thanks for any help.
