Navigation service: Navigate to specific page??

[Former Member]

Hi Experts,

i have a Abstract Portal Component that validates userID & password . i call the Navigation service inside it

...
..some code for user validation/logging here
                
 INavigationService navSrv = (INavigationService)PortalRuntime.getRuntimeResources().getService(INavigationService.KEY );
 Hashtable  environment = new Hashtable();
 IUserContext userContext = request.getUser();
 if(userContext!=null)
 {
 	environment.put( INavigationConstants.ENV_PRINCIPAL, userContext );
 	     
 }
 
 INavigationNode node = navSrv.getFirstNode(environment);

now i wish to navigate to a PAGE at pcd location ROLES://pcd:portal_content/my.org/myorg.ab.eview1

how can i do it ??

Hi,

You have two options, either use EPCM object which has method to navigate:

The second option is to build URL with NavigationTarget parameter:

Hi Praveen,

With EPCM its Javascript & workprotect mode dependency associated. Is there any other clean method, like a service or interface available that makes my component less dependent on EPCF framework & workprotect mode setting independent???

Hi,

Try this code:

INavigationGenerator navService = (INavigationGenerator) PortalRuntime.getRuntimeResources().getService(INavigationService.KEY);
//navigationNode = The node to which you want to navigate, here you can use navigationNode.getName() or navigationNode.getHashedName() depending on your need.
request.redirect(navService.getPortalURL( request,navigationNode.getName()));

If request.redirect does not work then try response.sendRedirect method.

Hi Praveen,

getPortalURL is not method of INavigationService & gives me a compile time error.

INavigationNode node = navSrv.getFirstNode(environment);
node.getName();

node.getName gives me the default PCD path to default startup page...however navigation is still not working....

Kind Regards

Hi,

If your node is getting pcd path to default startup page, then the node object corresponds to default startup page.

If you want to navigate to some other page then give appropriate node there.

The trick here is to build a proper navigation URL like:

http://myServer:50000/irj/portal?

NavigationTarget=ROLES://portal_content/myFolder/myRole

http://help.sap.com/saphelp_nw70/helpdata/EN/43/014421d21d6fade10000000a11466f/frameset.htm

Once the URL is ready, use request.redirect or response.sendRedirect to redirect to that node.
