Thanks for your message. I'll try to explain more clearly:
Page and menu definitions are stored in two files, pages.xml and menus.xml,
which are referenced in the web.xml as follows:
<servlet>
<servlet-name>TilesServlet</servlet-name>
<servlet-class>
org.apache.tiles.web.startup.TilesServlet
</servlet-class>
<init-param>
<param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
<param-value>/WEB-INF/pages.xml,/WEB-INF/menus.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
Page definitions consist of templated JSPs, plus a menu item e.g.
<definition name="/menulayout"
preparer="com.rbsg.application.cws.brand.jsf.XXXBrandPreparer"
template="/templates/layout.jsp">
<put-attribute name="banner" value="/banner.jsp" />
<put-attribute name="title"
value="XXXXX Message Application" />
<put-attribute name="header" value="/header.jsp" />
<put-attribute name="navigation" value="/navigation.jsp" />
<put-attribute name="menu" value="nav.main" />
<put-attribute name="footer" value="/footer.jsp" />
</definition>
The menu item ("nav.main" above) consists of menu entries, plus a rules
definition:
<definition name="menu.messaging.createmessage"
extends="menu.mainMenuLayout"
preparer="com.rbsg.application.cws.web.menu.jsf.TilesMenuRuleControlPreparer">
<put-attribute name="id" value="menu.messaging.createmessage" />
<put-attribute name="title" value="Create message" />
<put-attribute name="link" value="/createmessage.jsp" />
<put-list-attribute name="rules">
<add-attribute value="rule.menu.messaging.view" />
</put-list-attribute>
</definition>
All of these are read and processed by Tiles automatically & successfully. The
preparer class TilesMenuRuleControlPreparer in the menu is supposed to do
retrieve the rules definition ("rule.menu.messaging.view" in the above case),
and process it according to our security rules.
A rules definition is defined as follows:
<definition name="rule.menu.messaging.view">
<put-attribute name="type" value="one_role" />
<put-list-attribute name="roles">
<add-attribute value="ROLE1" />
<add-attribute value="ROLE2" />
<add-attribute value="ROLE3" />
</put-list-attribute>
</definition>
Ultimately I want to retrieve the rules definition, retrieve the roles
specified and process them according to our own security standards here.
Where it's falling down is that in the TilesMenuRuleControlPreparer class, I'm
trying to retrieve the rules definition as follows:
DefinitionManager definitionManager = new
DefinitionManager(
"org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG");
Definition def = definitionManager.getDefinition(name,
tilesRequestContext);
This is failing with a NullPointerException - on debugging, I see that the
Factory instance within the DefinitionManager is null.
I'm trying to find a way to refer to the definition files read in
automatically, so I can retrieve the rules definitions from there.
I hope this explains it further - if not, please get back to me.

Jim

Subject: Re: Issue with retrieving Tiles definitions in code
Can you explain what you need in a more abstract way?
What definition files are you reading?
How do you want to override the definitions defined there?
I would like to have a broader knowledge before I can help you.
