Hi Joseph,
Your message is very interresting ....
Actually I define my bean contract like this :
<jsp:useBean id ="contract" scope="request"
class="be.eTrust.trustedSeal.service.bean.Contract" />
but in my code, I retrieve a contract element from a vector of
contracts...
contract_in_vector =
(String)request.getParameter("contract_in_vector");
Vector contractVector = (Vector)
session.getAttribute("contractVector");
int i = Integer.parseInt(contract_in_vector);
contract = (Contract) contractVector.elementAt(i);
And now, I know what was the problem !!!
But it's strange because somewhere in my code, I use <jsp:getProperty
.../> for other contract's field
and that works !?
Thanks you very much
Thierry

I didn't see the original message in this thread, so I'm missing some
important information - but it LOOKS like you didn't put the bean in the
page context, via <jsp:useBean />. In JSP, you can use local
declarations as
such:
<% myClass bean=new myClass(); %>
... which doesn't put the bean in the page context - just in the current
method. Thus, the sequence:
<% myClass bean=new myClass(); %>
<jsp:getProperty name="bean" property="prop" />
...will and should fail.
The answer is, as stated, to use <jsp:useBean />. The following snippet
is
nearly equivalent to the previous snippet, with the exception of being
correct:
<jsp:useBean id="bean" type="myClass" />
<jsp:getProperty name="bean" property="prop" />
Again, this is the *common* cause for this kind of problem. It may be
that
there's another issue that the source would reveal.
