[Jboss-dev-forums] [Design of JBoss Portal] - some thoughts on possible enhanced portal features

[mholzner <nu...@jb...>]

It would be nice if the portal did provide a facility to do things like a portal wide search. The way I'd invision this is as follows: 

* the portal publishes a set of supported features (like search), similar to the way modes and window states are published right now
* the portlet publishes the features it supports (a subset of the ones provided by the portal) in jboss-portal.xml: (features that are not supported by the portal will be ignored)


  |  <portlet>
  |     ...
  |     <features>
  |        <doEvent/>
  |        <doSearch/>
  |     </features>
  | 

The portlet would need to implement additional interfaces that correlate with the feature, like 


  | public Class MySearchablePortlet
  |   extends GenericPortlet
  |    implements JBPSearch {
  |    ....
  |    public SearchResult doSearch(SearchCriteria crit){
  |        // do something useful 
  |   }
  | }
  | 

Code that wants to search the portal could do that at various scopes: 


  |    Context ctx = new PageContext(); // current Page
  |    // Context ctx = new PortalContext(); // current Portal
  |    // Context ctx = new PageContext("portal:portalName/page:pageName"); // specified Page
  |    List searchablePortlets sp = (List)ctx.lookup("java:comp/feature/search");
  |   for (Iterator i=sp.iterator();i.hasNext(); ){
  |      PortletSearchLink link = (PortletSearchLink)i.next();
  |      SearchResult result = link.execute("some criteria");
  |      html.append(result.toLinkURL().toString());
  |   }
  |   // or List searchResults = PortalSearch.execute(sp, "some criteria");
  | 

similarly events could be handled: 


  |     
  |    public void processEvent (PortletEvent ev){
  |       ev.getParameterNames();
  |       ev.setRenderParameters();
  |       ev.setPortletMode(Mode.VIEW);
  |       ev.setWindowState(State.NORMAL);
  |       ev.getSession(Session.APPLICATION_SCOPE).setAttribute("blah", "blahblah");
  |   }
  | 

Events can only be fired from action requests of another portlet. 
process event is very similar to processAction, except that it only has a subset of the ActionRequest functionality available (there is no Response)
