[jboss-dev-forums] [QA of JBoss Portal] - Injecting MC beans into the servlet context

[julien@jboss.com]

- MC is able to pick beans from a factory.
- MC is able to inject beans into a Map.

given that we can have a bean factory that produces a POJO that has a Map as property. That Map is a wrapper around the ServletContext attributes.


  | public class ServletContextAttributes 
  | {
  |    private final ServletContext context;
  |    public ServletContextAttributesInj(ServletContext context)
  |    {
  |       this.context = context;
  |    }
  |    public void setAttributes(Map attrs)
  |    {
  |       for (Iterator i = attrs.entrySet().iterator();i.hasNext();)
  |       {
  |          Map.Entry entry = (Map.Entry)i.next();
  |          String name = (String)entry.getKey();
  |          Object value = entry.getValue();
  |          context.setAttribute(name, value);
  |       }
  |    }
  | }
  | 

For the bean factory one already exist in the test module : org.jboss.portal.test.framework.TestBeanFactory

Then at startup of the servlet context listener we would have something like:


  | public void contextInitialized(ServletContextEvent event)
  | {
  |    // Create wrapper that configures
  |    ServletContextAttributes attrs = new ServletContextAttributes(event.getServletContext());
  | 
  |    // Configure MC
  |    TestRuntimeContext runtimeContext = new TestRuntimeContext("jboss-beans.xml");
  |    runtimeContext.addBean("ServletContextAttributes", attrs);
  |    runtimeContext.start();
  | }
  | 

and in jboss-beans.xml we would have something like :


  | <deployment ...>
  | 
  |    ... <!-- Declare all beans that are wired like AuthorizationDomainRegistry, etc... -->
  | 
  |    <!-- That's one bean that interest us to be injected in the servlet context as an attribute -->
  |    <bean name="PortalObjectContainer" class="org.jboss.portal.core.impl.model.portal.PersistentPortalObjectContainer">
  |       <property name="sessionFactoryJNDIName">java:/SessionFactory</property>
  |       <property name="authorizationDomainRegistry"><inject bean="AuthorizationDomainRegistry"/></property>
  |       <property name="portalAuthorizationManagerFactory"><inject bean="AuthorizationManagerFactory"/></property>
  |       <property name="contentProviderRegistry"><inject bean="ContentProviderRegistry"/></property>
  |    </bean>
  | 
  |    <bean name="ServletContextAttributes" class="ServletContextAttributes">
  |       <constructor factoryMethod="getBean">
  |          <factory bean="BeanFactory"/>
  |          <parameter>ServletContextAttributes</parameter>
  |       </constructor>
  |       <property name="attributes">
  |          <map keyClass="java.lang.String">
  |             <entry>
  |                <key>PortalObjectContainer</key>
  |                <value><inject bean="PortalObjectContainer"/></value>
  |             </entry>
  |          </map>
  |       </property>
  |    </bean>
  | 
  | </deployment>
  |
