We used the JBoss Portal API to create pages dynamically. I figured out how to do it by downloading the JBoss Portal source and reverse-engineering the admin-portlets :).

You will need to access the PortalObjectContainer MBean to create pages and add portlets to those pages. Here are some snippets (out-of-context, though):

// creating a page (parent page must exist)
PortalObjectPath portalPath = new PortalObjectPath(pathToParentPage, PortalObjectPath.CANONICAL_FORMAT);
PortalObjectId id = new PortalObjectId("", portalPath);
PortalObject object = getPortalObjectContainer().getObject(id);
PageContainer parent = (PageContainer) object;
Page page = parent.createPage("My Page");

// adding an instance of MyPortlet (instance must be created beforehand)
Window window = page.createWindow("MyPortletWindow", ContentType.PORTLET, "MyPortletInstance");

TransactionManager tm = null;
try {
 InitialContext ic = new InitialContext();
 tm = (TransactionManager) ic.lookup("java:/TransactionManager");
 tm.setTransactionTimeout(600);
} catch (NamingException e) {
 throw new RuntimeException("TransactionManager konnte nicht erzeugt werden!", e);
}
tm.begin();
try {
 MBeanServer mbeanServer = MBeanServerLocator.locateJBoss();
 PortalObjectContainer container = (PortalObjectContainer) MBeanProxy.get(PortalObjectContainer.class, new ObjectName("portal:container=PortalObject"), mbeanServer);
 return container;
} finally {
 tm.commit();
 logger.trace("...beende JTA-Transaktion.");
}

Almost overlooked your performance-question:

I tested the automatic creation of 5.000 - 10.000 portal pages with 5 Portlets each, which was no problem (the database is the bottleneck here). Those pages all referenced the same 5 Portlet instances.

However, when creating 1 new portlet instance for each page, Jboss Portal cannot handle the several thousand portlet instances (the admin backend and the JBoss API do not respond anymore). No one should need as many different portlet instances, though.

I do not understand what you mean by portlet preferences.

Hi

Can you please explain the procedure to create a dynamic portal page.

Hi

Can anyone help me out on this...

My Requirement is like when a user clicks on a hyperlink in a portlet , which is on the home page of portal.

A Portal Page should be created dynamically and the respective application (based on the hyperlink data) should be

loaded in an  other portlet in that particular dynamically created Portal Page.

Please give me some suggestions...

Thanks.

Hi,

What we do is redefininig the defaut PortalObjectContainer.

When the user clicks a link, we create  DynamicWindowBean or DynamicPageBean and store them in the user's session.

Then, our portalObjectContainer looks for this dynamicWindow and return them as DynamicWindow or DynamicPage objects (which are our implementation of the Portal Window/Page Interface).

It needs a good experience of JBoss Portal to implement.
