Re: question for accessing managed bean/backing bean from jsp page

[Yasushi Okubo]

Hi,

I read some tutorial slides, but this was not what I was looking for.
In fileupload_showing.jsp, jsp tags were embedded like following.
Then, I want to access some data [lists, arrays etc] defined/initialized 
in managed bean/backing bean from this jsp page inside scriptlet <% .. 
%> tag, not in html sections
Is it possible to do so ?
If it is not possible, is there way to use f:param to send a list data 
?  It looks value property  only accepts String type, but I would like 
to know the way to send a list (collection) to the server if such method 
exists ?

Thanks,
yasushi

  String contentType =
(String)application.getAttribute("fileupload_type");
  String fileName = (String)application.getAttribute("fileupload_name");

You should use JSF Expression Language (EL) to do this. It is similar to
using JSTL with one or two minor differences.
Your backing beans can be access using the following syntax

value="#{testBean.property}" where testBean is a managed bean and 
property
follows the standard java bean get/set patterns. You should also note 
some
of the discussions about incompatibility between JSP and JSF. You 
might want
to look at some of the MyFaces examples to get a clearer idea of how 
to use
JSF in a page. There is lots of good intro material here

Hi, Julian
I will try this shortly.

By the way, I see external links in web.xml for JSP 2.0/servlet 2.4, 
but  does it cause a problem when their server is down on boot ?

thanks

Subject: question for accessing managed bean/backing bean from jsp page

Hi experts,

I would like to access data structures defined in managed 
bean/backing bean
from jsp page.  For example, when I see myfaces file upload example, 
jsf page is taken a
user to jsp page, and I would like to access managed bean from this file
upload jsp page.
Could you someone direct me an example or explain to me how I can do 
that ?

So, if I have a managed/backing bean called testBean, how can I 
access it
from fileupload_showing jsp ?

Thanks,
yasushi
