Calling Portlets in Portal Pages

Guys,
Can anyone guide me , how can I call a portlet by clicking a link in another portlet?
Please note that I dont want to call a JSP page , but a portlet.
Thanks in advance,
-Sarma.

But can you call multiple portlets from one portlet, so for example
clicking a link in portlet a updates portlet b and c and if so how?

If I understand correctly what you are wanting to accomplish, I think you
should just use the Portlet tag createWebflowURL and specify the portletyou
want to change the state of...as follows
<portlet:createWebflowURL portletName="portletName" event="link.name"
extraParams="<%= extraParams %>" namespace="portletNamespace" >
hope this helps,
Dave

Portal form custom button to call new portal page

Portal 3.0.9
I can create a portal form componment which sets session variables appropriately based on a custom button. I can get a 2nd component such as a report to read this session variable ok as long as it on the SAME portal page.
However, how do I get the form (exposed as a portlet on a page) to call A DIFFERENT Portal page which contains a number of application components reading the previously set session variable? I do not want to call the module directly as it will appear in a popup window.
I've tried using owa_util.redirect_url('page url'); but this gets ignored and the same page is refreshed.
Any ideas?
John

Hi,
You can call the new page in the success procedure of the form
example
declare
l_url varchar2(2000);
begin
l_url := 'cut and paste the page link from the navigator';
go(l_url);
end;
Thanks,

Calling portal page

Is there an API call to call a certain portal page?
The only way i've found a way of doing this is using the following URL:
click here
Where _pageid is different for all pages. This is not very clever in case i decide to change the form at a later stage, or even when i implement the application to a different server the pages might be given different IDs.. So, how can i do this? I'd like to call the different pages (portal pages) using name instead of ID..

Check out the answer to "How can I define a bookmarkable URL for a Portal Page?" from the FAQ, or search for "direct access url" in the online help. It shows you how to call a page by its name.

Calling Portal page by name

In 9iAS Release 1, we can call a specific portal page using the following URL:
/pls/portal30/url/PAGE/page_name
Is there any similar url to call pages in Release 2?

Malin,
I have tried that earlier. It was not working.
I just tried with giving page group name as well. Now it's working.
/pls/portal/url/PAGE/<page_group_name>/<page_name>

Dynamic portal page generation

I wrote a jsp page to display the available discoverer reports to an user. User selects a few of the reports (no more than 6) and adds them as his favorite. I add this information in a custom table. Now I want to generate a page called "Report Favorites" for that user with his favorite reports. i.e I need to basically add 6 worksheet portlets to this page and then display the page. Is this doable? If so, what are the steps?

There are no public APIs to add portlets to portal pages.

How to show or hide portlets dynamically on a Portal Page

Dear All
1. I have a Portal Page with One Portlet in the top having like 5 Buttons. Each button click should display a separate portlet in the bottom on this same page.
2. I have Top Portlet. For bottom I have 5 Portlets P1, P2, P3, P4 and P5. On my .portal file, I dragged and dropped top portlet and all these 5 Portlets one below each other.
3. Now, I am trying to use BackingFile approach at PageLevel/Portlet level, to get the details of button clicked in top portlet (like name etc), and then show only one portlet at a time in the bottom section (using portlet backingcontext show/hide APIs). I do need to compare the bottom portlets defintion_label etc. which is fine for now.
Is this the right approach...?
Or do I have to use Portlet Custom Event approach. So top portlet will trigger event everytime button is clicked with some payload. And bottom 5 portlets listen to that event and show/hide accordingly. But in this approach, I have to attach backingfile to all the bottom portlets to listen to them.
All the portlets are Pageflow based Portlets. Any ideas or any other simpler approaches, are highly appreciated.
Thanks
Ravi Jegga

Hi Kevin
1. Thanks a lot for the pointers. I will go with Events. So for bottom Portlets, I will use the same BackingFile. But still it is going to be custom Event. Because only one portlet will be shown. So its like my payload will be portlet def label. In Backing File, I will compare this payload with actual dynamic value and if same, show or hide that portlet. Please let me know if this is correct approach.
2. Now each one of the Bottom Portlets is a complex pageflow portlet with many buttons of their own. So everytime a button is clicked or action is invoked, the Backing File gets called. And I had to somehow know that the same portlet has to be shown or the show/hide logic should not be called. Is there any way, where backing file gets called or just listen for Events triggered only from main top portlet.
Thanks for the other message, where looks like you already gave lots of pointers. I will go through them.
I will design and test this out and will keep you posted with my results.
Thanks a lot again

Refreshing a single portlet rather than the whole portal page

Ok, here's my situation.
I have two pdk portlets on my portal that communicate through page parameters. Portlet A has a bunch of search fields, a customer drop-down list, parts drop-down list, division, etc. Portlet B takes those parameters, queries the database, and displays the results. I would like to be able to refresh portlet B without reloading the whole portal page.
I have onchange events on all of my drop-downs that will do a javascript post back to portal, which will in turn set my page parameters, and I see there is a 'refreshPortlet' function in a javascript file that portal provides that will refresh a single portlet based on a portletReferenceId. It is normally called when a refresh button is clicked in the portlet header, but I don't see any reason I can't call it after my javascript post, that is, if I had the portletReferenceId for the other portlet. I thought about making a hidden html table on the page that, I could fill with the portlet names and ids for each portlet as they load, that way I could reference that list from any portlet. The problem is I can't figure out where the ids are coming from. Based on the code behind the button, the function is looking for something like this 646_701285_646_1_701271, but the closest thing I can come up with is this 676114_POSTCONTENTPORTLET_467414915 which I got from PortletRenderRequest.getPortletInstance().getInstanceName(). As you can see, it's not even close. Does anyone know where the correct id could be coming from? It's got to be available to me somewhere, doesn't it?
The only other option I can think of to accomplish my goal is to use straight up ajax to display portlet B, but that kind of defeats the purpose of portal doesn't it?
Any help would be greatly appreciated.
Thanks,
Doug

You can use Ctrl+F4 to close the current tab. I don't think that you can change the Alt+F4 action with Keyconfig.

How to apply different styles to Portlets on the same Portal page?

How do you apply different styles to Portlets on the same Portal page?
I'm new to this kind of thing, but understand that something called "cascading style sheets" can help here?
What are these, how do you use them, and can you make different Portlets (all types - PL/SQL, Java, Applications, etc) on the same Portal page have different styles assigned?
Thanks!

Jeff,
Apply Oracle Portal styles at the region level. Your portlets within each region will inherit the style defined for the region.
You may want to check out Report #40050 at portalcenter.oracle.com, "Design an Attractive and Compelling Portal Interface" for a good overview of the various design features of Oracle Portal.

Calling portal framework page from non portal page

Hi,
We are having some difficulty in passing control from the non portal pages to
the Portal Pages.
To explain you more elaborately, I am writing down the scenario:
Both our portal and non portal pages reside under the same web application folder.
We have a Portal Page containing one portlet.Clicking on one of the hyperlink
on this portlet page takes us out of the portal environment where we are doing
some processing.
(Why we are going out of the portal environment is because we want to call the
existing pages as it is and our intention is not to make the existing pages portal
enabled to start with).
Somewhere down the journey on the non portal page, there is a requirement to call
the Portal Framework page.
We can call the portal Framework page from the non portal page by hard coding
the URL of the Portal page by writing something like this in href:
http://localhost:7501/application?origin=content.jsp&event=bea.portal.framework.internal.portlet.event&pageid=home&portletid=bachome_carsearchlink&wfevent=link.next
But this is not what we want. We want to call the portal page without hard coding
the URL.
If we use portlet tag in non portal page to call the Portal Framework page ( <a
href="<portlet:createWebflowURL event="link.next"/>">Next Page</a>), it throws
us error "Could not find current Portlet State" which is quite understandable,
because portlet state is now lost.
Is there any way we can achieve this .
Any suggestions or ideas?
Thanks
Ajay

Hi
i think you should use portal:createPortalPageChangeURL (you are effectively changing
your portal page) .
if you want to invoke a specific event in your portlet webflow you can either
write a RefreshControllerIP or use WebflowJSPHelper.createWebflowURL.
bear in mind if you have urls that directly go to an intermediate event in the
portlets webflow you may need

Passing parameter to a portal page that display a WSRP portlet ?

I have created, deployed and regisered a WSRP portlet to Portal 10.1.4. I also create a portal page used to render this portlet. I would like to pass in a parameter xx (thru the HTTPRequest) when calling this page and have it visible to the portlet inside the page. Something like http://host:port/portal/page/portal/myPortlets/portletA?xx=123 where
"http://host:port/portal/page/portal/myPortlets/portletA" represented my portal page and "xx=123" is what I want my page to see.
Is it even possible/support by Portal 10.1.4 ?
Thanks.

Unable to bind portlet parameter with page parameter in webcenter portal

Hi All,
I am trying to bind portlet parameter with the page parameter so that I can ahieve some business requirements.
Here is what I did,
In my Portlet producer application:
1) Created standards based portlet (jsr 286) with view.jspx and edit.jspx with rest of the things being default.
2) In my portlet.xml created two parameters and assigned these parameters to the portlet created above.
3) In the view.jspx added couple of output label adf components in the page.
4) deployed this to integrated weblogic server.
In my WC portal application:
Created a new page and added the portlet to this page( WSRP connection already exists).
deployed portal application on integrated server.
In the edit mode of the page I added one page parameter(Param1) and some default (constant) value added.
What I want is this:
when Param1 value is One display first output label and
when Param1 value is Two display second output label.
I am using jdev 11.1.1.5.0 with integrated weblogic server.

There is no need to use page parameters for this.
You also have two types of parameters depending on what you want...
1) Preferences: these parameters can be used on a user based level. This means that users can personalize the portlets. When a user change the value of a preference, it is only applied for that specific user
2) Public parameters: these parameters are used to customize the portlet. The value you set in these parameter apply for all users.
I have made a simple example to show these two differences: http://www.yonaweb.be/PortletTest.zip
The portlet has 4 inputText on it. The first two can be set by specifying One or Two into the preference.
The other 2 inputText uses the value of the public parameter.
You should only deploy the portlet and consume it in a webcenter application. In the webcenter application, you don't need to do anything special. All is done in the portlet.
I am guessing you don't have written the code that will get the value of the parameter:
in case of a preference you will get the value by following code:
   PortletRequest request = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
   PortletPreferences preferences = request.getPreferences();
   return preferences.getValue("outputparam", "One");In case of a public parameter (for customization instead of personalization) you use following code to retreive the value of a public parameter:
PortletRequest req = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
String param = (String)req.getParameter("PublicParam");
if(param == null)
      return "Three";
return param;This code can also be found in the sample portlet application.

Order of execution of JPDK Portlets inside the same Portal Page

We have 2 Sample JPDK Portlets from the same provider on our page
- A LoginPortlet that accepts the username and Password
- A Welcome Bin Portlet that shows the logged in user's details
Once the user enters username and password in the LoginPortlet, we authenticate the user and set his username and other details in the 'ProviderSession'.
Further, in the Welcome Bin Portlet, we access the username and other details of the user from the 'ProviderSession' and display.
Though this solution seems to be working most of the time, we have an issue at times when the Welcome Bin Portlet executes before the LoginPortlet and hence is unable to fetch the userName and other details which are not yet set in the 'ProviderSession'. Hence, wanted to know if there is an execution order that we can enforce on the Portlets in a Portal Page, so that we can mandate that LoginPortlet Rendering shall happen before WelcomeBinPortlet Rendering.
Further, had it been a JSR168 Portlet, I understand that we could set the details over to the 'ProviderSession' in the 'ProcessAction' method of the LoginPortlet, which for sure gets executed before the Rendering of all the portlets. Is there a similar way or a hack while using JPDK?

The Private Event Submission sample portlet shows how to achieve this. It is part of the PDK download.
