• How to add portlets JSR 168 Portal Web Logic

  I installed WebLogic Server 10.3, WebLogic Portal 10.3 and workshop 10.3 on a virtual Windows Linux (version 5.4 of Red Hat Enterprise Linux Server).
  
  I used Workshop for WebLogic to create a Web portal project and a portlet in the < BEA_HOME > /wlportal_10.3/samples/domains/portal field. I can view the page in the portal at http://localhost:7041/PortalOneWP/myportal.portal.
  
  Using NetBeans IDE, I created a JSR 168 portlet that is packaged in a WAR file. I put the file. WAR in the folder < BEA_HOME > /wlportal_10.3/samples/domains/portal/autodeploy
  
  How can I add this portlet to the page I have to the http://localhost:7041/PortalOneWP/myportal.portal?
  
  Thanks in advance for your help,
  Barbara

  Hello Barbara,.

  The problem is that your JSP attempts to use portlet_2_0 tag library, which works only with the JSR286. JSR286 only is not supported by WLP right now (although it will be in the next version), only JSR168 is supported.

  If you do not use the specific tag library JSR286 features, you may be able to just change the import of taglib to be "http://java.sun.com/portlet" (the library of tags JSR168) and everything should work. If it still does not compile with that change, watch the JSR168 tag library documentation and make sure that you use only tags and attributes that are supported in JSR168 tag library.

• Question of packaging portlets JSR 168

  Hello
  
  I have a bunch of Java (JSR 168, using Spring MVC) portlets (PortletOne, PortletTwo... PortletN) that I've created as individual Web portal projects and are contained in a portal REE project. This portal EAR is my unit of deployment and consists also of another project of Portal Web (Assembly.war) that contains an app.portal file where I intend to assemble all these Java portlets and use it to create a desktop computer. The reason for having all individual portlets in web projects that is clean is to export it to a device and use it as a shared library or package in the EAR another file as necessary.
  
  my application.xml looks a bit like this:

  <?xml version="1.0" encoding="UTF-8"?>
  <application id="Application_ID" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd">
  
       <display-name>MyEar</display-name>
  
       <module id="WebModule_1">
            <web>
                 <web-uri>Assemby.war</web-uri>
                 <context-root>appname</context-root>
            </web>
       </module>
  
       <module id="WebModule_2">
            <web>
                 <web-uri>PortletOne.war</web-uri>
                 <context-root>PortletOne</context-root>
            </web>
       </module>
       
       <module id="WebModule_3">
            <web>
                 <web-uri>PortletTwo.war</web-uri>
                 <context-root>PortletTwo</context-root>
            </web>
       </module>
  </application>

  But since all these WAR files are at the same level that I can't refer to definitions of context and the controllers for the portlets defined in each of these portlet WAR files (PortletOne, PortletTwo,...) of the joint web project that contains the file app.portal in Assembly.war. I tried to set up a structure of classes customized in weblogic - Chargers application.xml and put the war on a lower level assembly file, but the app even not a not deploy with IllegalAccessError as soon as a framework for each of the war files is saved by the hot deployment of processes. Moreover, when I deploy the EAR file, the portlets defined in each of the WAR files do not appear in the resource library, seen from the Portal Administration console.
  
  Suggestions how to assemble these common individual portlets in a web project, while keeping their packaged in the same EAR file? Other approaches are also welcome.
  
  I've already reviewed deploy these files of WAR portlet like Weblogic J2EE of shared libraries. But with this approach, the overall application response time is very slow despite exhausting all the tuning options and can also precompile JSP pages in shared libraries.
  
  Is to import the JSR-168 portlets using the import utility as WSRP portlets ARE a viable option? I'll be able to share in portlets all session variables, of fire and manage events and be able to precompile the JSP in Rible portlets?

  Hello

  Maybe the nested multiple classloaders involved with shared libraries approach slows down, it down-if this is the case, it would be difficult to fix.

  With the help of WSRP should work for you; There is a little more complex, but if you have relatively simple portlets, use methods and tags correct JSR168 (or done spring bridge), it shouldn't be too difficult to get to work. The IDE may be able to help you with that; You can create a new portlet type 'remote portlet' in your aggregate webapp, and a wizard will guide you through the steps. If you use the local proxy mode, individual portlet WSDL URL will be the URL of the Web application for each portlet on localhost.

  WSRP configuration can also be done dynamically in the tools of administration of portal, and even using a specialized tool to import JSR168, but these two options would create instances of database portlets and portals in your webapp library. It would be nice if your EAR group does not need to move to a different deployment environment, but if you need portability of the EAR in another environment it makes packing, as data is also necessary. If you happen to use WLP version 10.3, according to me, there is a bug that prevents the import JSR168 tool specialized to work, but the tool is documented here:

  http://download.Oracle.com/docs/CD/E13155_01/WLP/docs103/prodOps/deployment.html#wp1047337

  Because all WSDL URL show up only on the local host, when you compress the associate WAR file it should successfully deploy on all servers. Information about the local proxy mode, which should improve the performance of your configuration, are described here:

  http://download.Oracle.com/docs/CD/E13155_01/WLP/docs103/Federation/chap-Best_Practices.html#wp1010714

• interaction of JSR 168 portlets with a portal

  Hi, I'm fairly new to jsr 168 prtlets and how to use on a portal.
  I want to design two placeholders, one to the left and to the right. Then each placeholder has a jsr 168 portlet such as portlets on the left have buttons or hyperlinks and clicking on them, the page or action opens on the right portlet.
  
  Can someone guide me on how to code it. I use weblogic workshop for that. Please give me an example of code if you can.
  
  Thank you much for the help in advance

  John

  Hi John,.

  In JSR168, there are two "scopes" for the session - scope portlet (which is the default) and the scope. Your code would work except that you have found the scope of default by portlet session; you want the scope of application shared-of-everything-portlets.

  For that, all you need to do is to change your call:

  portletSession.setAttribute ("testVariable", "testing123");

  TO:

  portletSession.setAttribute ("testVariable", "testing123", PortletSession.APPLICATION_SCOPE);

  and modify your call:

  String value = (String) portletSession.getAttribute ("testVariable");

  TO:

  String value = (String) portletSession.getAttribute ("testVariable", PortletSession.APPLICATION_SCOPE);

• Cannot bind the portlet parameter with the webcenter portal page setting

  Hi all
  
  I'm tying portlet parameter with the setting of the page so that I can reach some needs of the company.
  
  Here's what I did,
  
  In my producer of Portlet application:
  (1) created standards based portlets (jsr 286) with view.jspx and edit.jspx with the rest of the things being default.
  (2) in my portlet.xml created two parameters and receives these parameters to the portlet created above.
  (3) in the added view.jspx output torque label adf elements in the page.
  (4) deployed this integrated weblogic server.
  
  In my WC portal application:
  Created a new page and add the portlet to this page (WSRP connection already exists).
  deployed applications of portal on the server integrated.
  
  In page editing mode, I added a parameter (Param1) and certain value (constant) default page added.
  
  What I want is this:
  What value of Param1 is a view first label of output and
  What value of Param1 is display two second label output.
  
  I use jdev 11.1.1.5.0 with integrated weblogic server.

  (1) I do not set the value in the portlet code. This is supported by the application of Portal WebCenter! When you insert the portlet on a page and Runtime edition mode, press the button customize (an icon of Gable at the top right of the portlet). The first tab is the tab settings of the portlet. This tab is generated by the infrastructure by reading the specifications of portlets. As soon as you change the value it and press ok or apply, the value can ask of the portlet code I provided. That's why you can't find a code to set this value.
  (2) responded to 1 I guess :)
  (3) also partially answered 1 :)
  To change the value of a second, you must customize the portlet. This is possible by logging into the portal. You should see a pencil icon in the upper right of the portlet. When you click on it, it will open the page of edit.jspx that can be used to set preferences, as you can see in the code.
  Note that edit.jspx and the code to handle fields in the portlet bean are generated by Jdeveloper. I've not written. This is done by JDeveloper when you add a preference during the portlet Wizard.

  I hope this helps.

• IPC using JSR 168 in Weblogic Portal

  Hello world
  Time and now I see a few articles on the most essential notion that we try to acquire knowledge and to produce in our portal application is inter-portlet communication. I found a lot of samples for websphere based of portlets and a few extensions more to support interportlet communication. Let me introduce to you in a concise way of what we are trying to achieve, we try to create inter portlet communication without using session context, event handlers and the backup files. Add to this that we try to have an ajax based approach to refresh portlets. We started using portal weblogic portal development just a month back and its all Greeks and latins for us to start with very little information, just, I think that I will get some answers from the experts here. I also understand that this post may be the requirement for most of the people who work with the portal environment. Please post your suggestions/samples on this approach and the ways to do this. Thanks in advance.

  Ashwin

  Ashwin Hello,

  Thank you to detail what you want to do. From your description, I think certainly you don't want to use asynchronous desktop. In the async Office, portlets refresh when they are interacting with on the customer or when they receive an event of the portlet is interacting with (and for the next version of WLP, whenever they welcome an audience of JSR286 make parameter). But WLP 10.3 for your use cases events are going to be the way forward to ensure the good portlet (s) are updated in desktop async mode.

  So for your use case described below, I think that you would be events want to implement something like this:

  High portlet fires an event (I'll call it "filterParams") when it gets to a call from processAction() indicating that the user interacts with this portlet and filter settings may change. To the event payload you might use a simple map of the filter parameter name / value of the filter setting.

  Second portlet listening event "filterParams" (from the top of the page portlet), so that it can cool off and display the AAU links based on what is at the top of the page portlet (which he received in the event payload). The second portlet also sends an event in its method processAction(), which I will call 'linkSelected', with a payload of the link that should display the third portlet. In the Manager 'filterParams' of events the second portlet can also send a "linkSelected" event to cause the third portlet refresh if you want to only it when the top portlet filter of modified page settings.

  The third portlet would listen for the "linkSelected" event and set its content appropriately from the link he received in the event payload.

  It would be possible to upgrade to JSR286 events in the future if you implemented this way with JSR168 events now.

• Facebook as a source of authentication Oracle WebCenter interaction

  I was wondering if anyone out there has built-in Facebook/Twitter/OpenID etc as auth source their WCI portal.
  
  I ask because the process of creation/invitation of current account is a bit dated and we think it is a barrier to adoption for our external users, and disables some of our professional users, who then use social .com sites.
  
  Would like to hear from anyone who has had the success (or failure) in this area.
  Thank you

  Hey Geoff, just, I was chatting with Igor on this issue and he said that they look at this as a potential function of the order of 12g WebCenter which is still in prototype. And although he does think that everyone has done, he does not write a customized for WCI to connect to external social networks authentication source would be too difficult. But that would require a custom at this stage development.

  Thank you
  pp

  If you are using 11g SOA Suite it is not, Oracle Enterprise Service Bus, it was renamed as a mediator. Ombudsman is now part of the composite.

  To answer your questions.

  1. no they are not the same, but they can perform similar functions. Oracle ESB is 10g and is part of the installation of 10g 10.1.3.1 located on OTN, not sure you can get the standalone version without triggering a SR, you can find it on eDelivery.oracle.com. If you have installed OSB does not require to have the Oracle ESB like OSB will happen all what BSE Oracle does, (outside the field of card values, but it can be done in BPEL)

  2 ESB is a generic term and does not mean it's Oracle, there are many BSE there. I would say OSB if it is a work of Oracle, but you may have known at once. If you know the mediator you know Oracle ESB so you don't need to download.

  3. you don't deploy SOA/BPEL in a service bus. They are deployed to and application server where SOA Suite is deployed. Now SOA Suite is certified with Oracle Web logic but will come the other application servers. Having said that your SOA/BPEL application can consume services on other application servers as long as the WSDL and endpoint are accessible from your machine SOA Suite. Web services will be considered. The JSR168 standard means that if your portal is compatible JSR168, then you can use JSR168 portlets, these portlets can be deployed on any 3rd party app server.

  see you soon

• WSRP Portlets - renowned HTML elements

  Moved from Webcenter spaces.
  
  All,
  
  I have a JSR-168 portlet that I WSRP-ed by using the wsrp-predeploy tool. I have this saved in Weblogic as WSRP producer and added to the Webcenter spaces. What I notice is that when rendering on the spaces, HTML elements, including the names of javascript functions are renamed and preceded by some string values. For example my input fields have '_adfp_portlet_field___adfpfp_f1723360181_adfpsep_f0_adfpsep_', was added to the beginning and my javascript (in the script tag) function names have "adfp1723360181_" added.
  
  The portlet I (this is the portlet JasperServer fwiw) uses Javascript features for navigation. As a result of this change of name, none of the button controls works in the portlet.
  
  Is that what I can do about it?

  Try to make the portlet in an iframe. I don't think that your components will have the prefix to their id then.
  You can do this in the portlet display options and make in iframe portlet set to true.

  Hello

  It really is not much integrated in the framework, WLP to support the passage of information between .portal files. By design, they are the 'level' of a portal which is the highest level information is shared between portlets.

  So my first suggestion would be to put all the portlets you want to interact together as part of a 'portal', in one .portlet file, and then you have many options for the transmission of data between portlets:
