Re: how to access application bean data

[Ralf Riedel]

Hallo Michael,

thanks for your advice, but I'm not sure whether I understood you right. What I want to achieve is the following: In the .jsp file, two beans are initialized: the application scope bean holding a DB connection pool, and a page (or whatever) scope bean, uses request data to initialize itself. Later in the .jsp file, the page scope beans data should be made visible through a <jsp:getProperty ...> action. The reason for this is, that as less as possible scripting should be packed into the .jsp file.

Ralf,

JSP can access your Java bean directly.  In the sun demo, it demonstrates
how to do this.

Provided here is a snippet of the Calendar example:

>>> jsp1.0/examples/jsp/cal/cal1.txt <<<
 

<%@ page language="java" import="cal.*" %>
<jsp:useBean id="table" scope="application" class="cal.TableBean" />

<%
        table.processRequest(request);
        if (table.getProcessError() == false) {
%>

<!-- html table goes here -->

Subject: how to access application bean data

Hi there,

I'd like to access data I've stored in an application bean from within an
other beans code. The application bean manages a pool of db connections,
from which other beans may want to grab one to get able to access the
database. Now, the only way I know to access the application bean later is
from a servlet through the ServletContext. So my question: Is there a way
the get on the data stored in the application bean without using servlets,
e.g. directly from the code of the bean which needs database access?

many thanks,
ralf
