The situation is :
I create class that extends ApplicationServlet and I specify it as the
tapestry main servlet in web.xml. In this class I call a class that
initialise some "application objects" such as list of element common to
everybody from the database.
My class also set a bean member and implement the get/set method.
I also specified this class as an ASO as you told me to do Geoff and I put
the inject tag in my Home.page.
At the loading of the application, my "application object" is loaded
normally and contains all the list.
When I call the Home.page, the inject seems to work and the pageBeginRender
is called normally. I call getMyASO() I declared abstract, but when I try to
get the "application object" it is null!!
I think Tapestry recreate an instance of MyASO instead of directly get the
first loaded :
web.xml
...
<servlet>
<servlet-name>dm</servlet-name>
<display-name>DM Initialization servlet</display-name>
<servlet-class>dgt.dm.controller.DossierManagerApplication
</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
...
hivemodule.xml
<?xml version="1.0" encoding="UTF-8"?>
<module id="dgt.dm.controller" version="06.02.01" package="dgt.dm.controller
">
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="dossierManagerApplication" scope="application">
<create-instance class="dgt.dm.controller.DossierManagerApplication"/>
</state-object>
</contribution>
</module>
DossierManagerApplication.java
public class DossierManagerApplication extends ApplicationServlet {
private ApplicationSettings appSettings = null;
public ApplicationSettings getAppSettings() { return appSettings; }
public void setAppSettings(ApplicationSettings appSettings) {
this.appSettings = appSettings; }
private InitServlet is = null;
public void init(ServletConfig arg0) throws ServletException {
super.init(arg0);
String webRootPath = getServletContext().getRealPath("/");
is = new InitServlet();
is.init(webRootPath);
appSettings = is.getAppSettings();
// NOT NULL WHEN I DEBUG
}
...
HomePage.page
...
<page-specification class="dgt.dm.pages.HomePage">
<inject property="dossierManagerApplication" type="state"
object="dossierManagerApplication"/>
</page-specification>
HomePage.java
public abstract DossierManagerApplication getDossierManagerApplication();
public abstract void
setDossierManagerApplication(DossierManagerApplication
dossierManagerApplication);
public void pageBeginRender(PageEvent event) {
DossierManagerApplication dossierManagerApplication =
getDossierManagerApplication();
ApplicationSettings appSettings =
dossierManagerApplication.getAppSettings();
// IS NULL
setRequesters(appSettings.getRequesters());
setLanguages(appSettings.getLanguages());
}
Thanks for help...

Thanks a lot, but I have a question again: To what, the id in the module
tag, refer? Is it the name of my context? is it app? is it the package where
something (what?) is store? Same question for the version.
Thanks anyway
