Hello,
[this should prob'ly be read with 'Developing with Apache Avalon' in hand]
I am trying to get Avalon to work.
I went through the DwAA, wrote the classes,
and now I seem to be missing the one last step:
How do I actuall _use_ them in a *.jsp page?
I call the Container (viz DwAA), which (I think) should in turn
instantiate/compose/configure/initialize all the components as described
in config.xml
-- cut --
<%@ page language="java" session="true"%>
<jsp:useBean id="container" scope="session"
class="net.templation.casopis.clanky.ContainerComponent"/>
initializing container ... <% container.initialize();%> done
-- cut --
It goes well till the
this.manager.configure(sysConfig)
call in container.initialize(), which throws NullPointerException. Why?
And after I, let's say, get over this, plus
this.manager.initialize(), the components are instantiated/composed/... ?
And my tiny little .jsp can continue as follows ?
-- cut --
<jsp:useBean id="repository" scope="session"
class="net.templation.casopis.clanky.DatabaseRepository"/>
<%
id = request.getParameter("id");
repository.FetchSomethingFromDatabase(id);
%>
-- cut --
And can I call the 'documents' component-instance (as described in system.xconf)
which (I think) is already set up for me, after the
container.initialize()? From where can I call it?
Thank you very much and please excuse a newbie's ignorance.
Jan
