Spring MVC Portlet in Weblogic Portal

Is there any sample application for Spring MVC Portlet(JSR 168) in Weblogic Portal ? If so, where can I download it from ?

you can get spring source code,then open spring samples folder,and spring portlet can transplant to weblogic portal

Spring MVC Portlet minimize not working on Weblogic 10.3.0

We have written JSR 168 Portlets using spring MVC portlet framework. Everything works fine except for the minimize portlet functionality.
The title bar changes that is minimize becomes restore but the portlet body (content) is always visible.
Please let me know if any of you faced this issue and how to resolve it.

Hello,
From what I can see from the Spring DispatcherPortlet source (I used http://www.docjar.com/html/api/org/springframework/web/portlet/DispatcherPortlet.java.html ), it looks like this is a bug in the DispatcherPortlet. The JSR168 / JSR286 specification requires that portlets not render themselves during the render lifecycle if they are minimized, and I don't see any code in the DispatcherPortlet that checks for the portlet state. From the source in the URL above, it looks like if you added this code at line 701 inside of the doRenderService() method of DispatcherPortlet and re-compiled that code, it might work for you:
        if(request.getWindowState().equals(javax.portlet.WindowState.MINIMIZED)) {
            return;
        }Alternately, you can change your portlet.xml so instead of using the Java class org.springframework.web.portlet.DispatcherPortlet you point it at your own class:
package sample.package;
public class MinimizedAwareDispatcherPortlet extends org.springframework.web.portlet.DispatcherPortlet
    @Override
    protected void doRenderService(javax.portlet.RenderRequest request, javax.portlet.RenderResponse response) throws Exception {
        if(request.getWindowState().equals(javax.portlet.WindowState.MINIMIZED)) {
            return;
        super.doRenderService(request, response);

Spring MVC Portlet Question in JDeveloper 11.1.1.4

Hello All,
I am trying to develop a spring mvc portlet and test it in Jdeveloper 11.1.1.4 (integrated weblogic server). Below is my portlet.xml ... I don't think portlet-class is getting loaded. Even if i put xxxxx in the classname i don't see any errors. Has anyone done this before, what to see if there is any suggestions.
I have a controller configured in helloWorld-portlet.xml and it is not getting invoked.
thanks in advance,

Announcing: Developing JSF Portlets with WebLogic Portal Whitepaper

Just Released: Developing JSF Portlets with WebLogic Portal Whitepaper
A supplemental developer's guide has been published to help guide WLP 10.x customers that wish to use JSF as the web framework for building portlets on WebLogic Portal. This is a sizable document (150 pages) that covers a large number of topics. It also coaches developers on best practices and common pitfalls.
Important: It also clarifies the supported configuration of JSF within Portal Web Projects. Workshop for WebLogic by default configures a web project in a configuration that is not supported by WebLogic Portal. The guide explains how to address this:
* Change from the unsupported MyFaces JSF implementation to the supported Sun Reference Implementation (RI)
* Change from the unsupported "client" STATE_SAVING_METHOD to the supported "server"
The guide can be downloaded here:

Hi Peter!
First, I wish to thank you for the great work.
We followed your whitepaper and managed to deploy a JSF portlet on WLS.
But we are not able to register it (consume it) as remote portlet in Oracle Portal 10.1.4. The error log is as follows:
An error occurred while trying to refresh the provider. (WWC-43190)
An error occurred during the call to the WSRP Provider:

Query- IPC using JSF Portlets in WebLogic Portal

The question is how to pass data when doing InterPortlet Communication using Local JSF portlets in Weblogic Portal.
I will eloborate on the particular scenario we have below.
Two JSF portlets are build (both are not using Java Page Flows). The first porltet has a table of data. When the user clicks on one of the items in the table (which is coded using <h:commandLink/> option), the second portlet should show some details on the item clicked.
For example:
If there is a list of books in first portlet, when clicking on one of the book name, the details of book should come up in the second portlet.
To achieve this, faces event was enabled in first portlet with requestAttrPersistence option set to session.
For example :
<netuix:content>
<netuix:facesContent contentUri="/bookList.faces" requestAttrPersistence="session">
<netuix:facesEvents>
<netuix:facesEvent action="/bookDetails.faces" eventName="bookDetailEvent"/>
</netuix:facesEvents>
</netuix:facesContent>
</netuix:content>
The second portlet was configured to handle faces events, particularly the bookDetailEvent.
Example:
<netuix:handleFacesEvent eventLabel="handleFacesEvent1" eventName="bookDetailEvent" fromSelfInstanceOnly="false" onlyIfDisplayed="true" sourceDefinitionLabels="JSFPortlet_1" sourceDefinitionWildcard="this">
<netuix:invokeFacesAction action="/bookDetails.faces"/>
</netuix:handleFacesEvent>
Going by this method, how can we find the particular book whose detail has to be shown? As in JSF, we dont directly access the request attributes, what is the ideal way to pass data from one page to other?
Please help on this.

i am also having the same problem.I tried by passing _nfls=false but it didn't work.Can you suuggest where do i need to set this or any other parametrs such as this programmatically?

ADF jdev 11g portlet in Weblogic Portal 10G R3?

Is possible to build a ADF Jdev 11g portlet and deploy it in a Weblogic Portal 10g R3?

Not with WebLogic Portal 10gR3, no, but that use case is one that will be supported in the upcoming release of WebLogic Portal, which will coincide closely with the release of WebCenter 11g.

NPE while registering Remote Portlet in Weblogic Portal 10.3

Hi,
I am on Weblogic Portal 10.3 and am trying to create a remote portlet in my portal application. The remote Portlet is hosted on OC4J 10.3.1.1.1 and is consumed properly on Oracle Portal without any errors, however, when I try to access the portlet's wsdl via the Remote Portlet Wizard, I get the following exception while registering.

Now I am able to display the initial page of the remote portlet. However, when I try to do some operations I m running into one more issue:

Is there anything futher I need to do?

Location of Login Portlet in Weblogic Portal 9.2

Hi All,
Does Weblogic Portal 9.2 provide its own Login Portlet or not?Actually I want to use login portlet that comes with Weblogic Portal 9.2 into my sample application.
If anyone has got idea about where is the login Portlet and how to use in our application then please let me know.All suggestions are welcome and thanx in advance.
Regards,
Chiku...

Hey Chiku,
There is a brand new login portal sample in Dev2Dev (thanks to Skip
Sauls).

Install of the OCS portlets on Weblogic Portal 8.1

is anybody who has installed the whole stack of Collaboration Suite on a Weblogic Portal v8.1?
if yes, had you encounter any problems? do you have some tips ? or documentations ?
do you keep the WebCache in front of the WLS ?
do you keep the HTTP Server in front of the WLS ?
Thanks you

As far as I know, OCS portlets are specific to Oracle Portal, therefore they can't work on other portals easily, if not at all.
2 solutions :
1) wait for ORacle to release JSR-168 compliant portlets (portable portlets ;-) )
2) develop you own portlets for BEA. OCS includes a whole bunch of web services that you can easily call from a java portlet, and you can use LDAP indentification on OID or even integrate into SSO, as an external application (quite easy also), or as a partner application (more difficult but better integration).

Using common httpsession in Remote Portlets of Weblogic Portal

I am using Oracle's Weblogic Portal and I am using multiple remote Producers in Portal application, I want too know if I can use common Http Session among multiple Producer Portlets?
I am consuming Portlets from Producers in one portal and I have one common Login for Portal.

There is a much easier pattern for this, but it may or may not serve your needs. You can use Community Preferences. You can set/get them from portlets, control who sets it using portlet security, etc. The one difference is that you won't see it enumerated with the other community properties when you edit a community in the admin view.
Another option is to do as you planned; you would need to use the plumtree server API to update the data, but you should be able to fetch it using the remote search API. might want to post questions on the respective discussions (native API and prc) for those questions...

Java Portlets only JSR 168 compatible Portlet in Weblogic Portal 9.x?

I and need to develop a JSR 168 Portlet that contains JSF components. I have looked through a lot of the training material, newsgroups and web sites for any information on how to perform this within the Weblogic Portal tools and have been unsuccessful.
Is there a way in Weblogic Portal 9.x to create a Portlet that is JSR 168 compliant and capable of containing JSF components through the tool interface?

IPC with JSR 168 portlets and WebLogic Portal 9.2.3

I have seen examples in this forum indicating that you can implement IPC in JSR 168 portlets by doing the following:
1. Fire a custom event in the processAction() method of one portlet.
2. Handle the custom event in another portlet that is listening for the event.
3. The listening portlet should contain a method such as
processMyCustomEvent(ActionRequest req, ActionResponse resp, Event event)4. The method is mapped as a handler for the custom event in the listening portlet's +.portlet+ file:
<netuix:javaPortlet definitionLabel="jsr168EventPortlet" title="JSR168 event portlet">
   <netuix:handleCustomEvent event="myCustomEvent" eventLabel="customEventOne" filterable="true" description="custom event handler">
      <netuix:invokeJavaPortletMethod method="processMyCustomEvent" />
   </netuix:handleCustomEvent>
</netuix:javaPortlet>However, the examples I've found in this forum seem to pertain only to installations of WebLogic Portal 10.x or higher.
Does this JSR 168 IPC approach work for WebLogic Portal 9.2.3?
(The example provided in the WL Portal 9.2.3 documentation uses a Backing File to handle the event instead of invoking a method in the portlet class itself.)
Any clarification that can be provided would be much appreciated. Thanks.
Edited by: user13297286 on Jun 15, 2010 2:02 PM

Hello,
Yes, JSR168 portlet IPC is supported in WLP 9.2, and you can use the "invokeJavaPortletMethod" (recommended) or the invokeBackingFileMethod in the .portlet file to configure your portlet to receive events.

Developing JSF Portlets with WebLogic Portal (Oracle White paper May 2009)

I have created a simple JSF Portlet following the steps delineated in paragraph 3.1.1 Creating a JSF Enabled WLP Web Project of the white paper mentioned above. I used Workshop for Weblogic 10gR3. When I tried to deploy that very simple portlet and portal I got this error message :
"!MESSAGE Unable to register J2EE shared library C:\bea\wlportal_10.3\samples\lib\j2ee-modules\wlp-sample-lookandfeel-web-lib.war".
Clearly the folder and file "samples\lib\j2ee-modules\wlp-sample-lookandfeel-web-lib.war" are not under my "C:\bea\wlportal_10.3". My question is where do I download it? Where does it come from?
Thanks in advance.

Maybe you did not include the samples when you installed Oracle WebLogic Portal? Now that this is an Oracle product, samples are not installed or configured by default. This is a change in policy from when WebLogic Portal was a BEA thing, so it takes some getting used to and there are probably plenty of places where documentation and papers could be enhanced to emphasize this.
In addition, it looks like there might be an error in the white paper with respect to configuring your web app to include samples. I don't see any mention of taking an extra step to include the sample facets in your portal app. This oversight may have been caused by the author working with a pre-release of Oracle WebLogic Portal that had not yet been "Oracle-ized" enough to get the default samples out of there. In the old days, I think the samples were automatically included in your portal web app.
To get the samples in a new portal web app while you are creating it with the IDE you can click the "Modify..." button on the first dialog. It is next to the "Configuration" text area. This pops up a dialog that lets you select the "Weblogic Portal Samples" facet for your web app.
To get the samples in an existing portal web app after it has been created, right click the app in the IDE, click "Properties...", click "Project Facets", and select the "Weblogic Portal Samples".
Sorry, I'm not sure what the remedy is for getting samples into an installed product that was not installed with the samples. Unfortunately, I think that is the problem that you need solved. Sorry about that. Hopefully you are working in a test or dev environment that makes it easy to blow away old installations and start over? If not, then maybe install it with samples someplace else and copy the samples/... dir over to your other install?

Thanks Brad !!!
It works...
earlier I had entitlements set only on Employee Portal and Calendar in the tree structure Community_repository > Calendar > EmployeePortal > Calendar.
It didnt work and throwed that error.
After your suggestion I set entitlements on groupware.calendar.appointment to create, view, update, delete and instantiate to true.
It worked, thanks for your help.
