I have found the solution, but I would like to ask the Portal developers if there is a more elegant solution. If not, will a later version of JBoss Portal support - injecting default portlets into "special" regions (like the navigation region, but with real portlets) - or support markup in layouts that specify portlets to be injected at the place of the markup, for example | <p:injectPortlet instance="InjectMePortletInstance"> | <parameters/> | </p:injectPortlet> | And the solution for Injecting content to a custom region for the current version is: 1. Create a class Named MyPageCustomizerInterceptor that extends ControllerInterceptor 2. Get JBoss source and copy the contents of: org.jboss.portal.core.aspects.controller.PageCustomizerInterceptor into your class code. Import a bunch of JBoss libraries 3. there is a part in the code in the "invoke" method: | if (tabbedNav != null) | { | .... | } | | instantly after this code insert the following (of course modified to your preferences). Modify the "BLAH2" and the "inject_region" strings to your needs. | | String toInject = "<h1>AT LAST! I have injected my custom stuff!</h1>"; | Map windowProps = new HashMap(); | windowProps.put(ThemeConstants.PORTAL_PROP_WINDOW_RENDERER, "emptyRenderer"); | windowProps.put(ThemeConstants.PORTAL_PROP_DECORATION_RENDERER, "emptyRenderer"); | windowProps.put(ThemeConstants.PORTAL_PROP_PORTLET_RENDERER, "emptyRenderer"); | WindowResult res = new WindowResult("", toInject, Collections.EMPTY_MAP, windowProps, null, WindowState.NORMAL, Mode.VIEW); | WindowContext blah = new WindowContext("BLAH2", "inject_region", "0", res); | rendition.getPageResult().addWindowContext(blah); | Region region = rendition.getPageResult().getRegion2("inject_region"); | DynaRenderOptions.NO_AJAX.setOptions(region.getProperties()); | 3. Put your classes into a jar and put them under JBOSS_HOME\server\default\lib\ 4. Modify JBOSS_HOME\server\default\deploy\jboss-portal.sar\META-INF\jboss-service.xml replace org.jboss.portal.core.aspects.controller.PageCustomizerInterceptor in | <mbean code="org.jboss.portal.core.aspects.controller.PageCustomizerInterceptor" | with the full classname of your class View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194164#...
