Hello: For portal 2.6.3 bundle there's no IPC documentation. The link http://docs.jboss.com/jbportal/v2.6/reference-guide/en/html/ipc.html does not exist any more. The sample code at http://labs.jboss.com/portal/portletswap/portlets_tutorial.html does not work since the next snippet of portletA does no work: PortalNode thisNode = req.getPortalNode().getParent(); // will return this Page as a node. | PortalNode linkToNode = thisNode.resolve("../default"); | PortalNodeURL pageURL = resp.createRenderURL(linkToNode); The nodes 'default' and 'IPC' don't exist, only the instance 'HelloWorldPortletAWindow' is resolved. Please assist!!!! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130198#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
