• 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

  I hope this helps!

• Portlets JSR-168 in WebCenter Interaction

  We exposed re-implement many of our portlets WebCenter Interaction in the JSR 168 standard uses the container of the JSR-168 WebCenter interaction. What we found, is that the stardard is fairly simplistic, and we do not find a way to access things like Id of the portlet or the URL of the Image Server, which we are accustomed to use. Is there a way to make use of these things in the WebCenter Interaction JSR-168 container?
  
  The main reason that we wanted to move to the standard is to facilitate future updates. We will have to move in the future everything on an IBM WebSphere portal that our company uses also, or if we stay with WebCenter Interaction, finally we heard that there could be major changes when the product merges with WebLogic portal.
  
  Thank you
  Tim

  Hello

  JSR168 is a fairly simplistic standard, but there are ways to do more things.

  For example, to get the portlet ID (I assume you want a single portlet instance ID and not an ID for that 'typical' portlet), you can use the PortletRequest.getWindowID () to return an ID for the single portlet user session.

  For the storage of URLs that need to be reconfigured depending on deployment, which is usually done with the preferences of portlets JSR168 portlet - portlet can read its value, which can be set by a developer or an administrator (or the portlet itself, if you wish). Deployed with portlets Java properties files can also contain this configuration information.

• 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.

• Re-direct URL with Oracle Portal.

  Hello
  
  We have some old applications based portals that we want to redirect to the new version and we tried to do a redirection of the httpd.conf file and restarted the server http, but his does not work.
  
  We have
  
  http://hts03:7778 / portal/page/Portal/TestMichael/StaffList and I want to re-direct to: http://hts03:7778 / portal/page/Portal/PG_SITELINK_V2/P_SITELINK_HOME
  
  So, we have in our httpd.conf file:
  

  redirect /portal/page/portal/TestMichael/StaffList http://hts03:7778/portal/page/portal/PG_SITELINK_V2/P_SITELINK_HOME

  So we ask what we did wrong and can we use redirects with Oracle Portal?
  
  See you soon,.
  Paul.

  Why not use a rewrite rule?

  RewriteRule ^ / portal/page/Portal/TestMichael/StaffList/portal/page/portal/PG_SITELINK_V2/P_SITELINK_HOME

  And don't forget to run dcmctl updateconfig TC - SST after updating the httpd.conf file manually. If you change if via Enterprise Manager, it is done automatically for you.

  In addition to defining the rights on the portlet, you need allow the region in the BEA Repository storing artifacts of collaboration (appointments). You will also need to call the collaboration of content types to give view rights users can instantiate.

• Do the Aqualogic Portal support portlet with in an iframe?

  AquaLogic portal - 6.1 MP1
  
  Thanks in advance

  You can't expect any portals features to work if you have an iframe in a portlet (using idk, analytics etc.).

  Its generally said that the portal don't support Iframes for the aforementioned reasons.

  You can just bring in the Applications in the portal as it is. Based on the schedule and budget, we brought our company to understand the implications in an application that uses iframes and fact.

  Make sure you put your portlet inside a stretch no layout, like PanelGroupLayout, don't put it inside the PanelStretchLayout and if you have a PanelCollection put the PanelCollection inside a PanelGroupLayout

• Disable/remove portlets from the portal

  I would like to disable/remove access to some portlets in portal so that they are not accessible to users. The portlets in question are the Collaboration (calendar, tasks, Discussion, Mail, AddressBook) those provided by BEA/Oracle. I know one option is to remove the facet of collaboration portal, but I need this facet to continue using GroupSpace.

  They should not be listed. Any API that returns a list of the portlets should not list of portlets which the appellant did not have access to see. I have validated with GroupSpace end-user customization tools, as you have indicated that you use GroupSpace. If the user do not have display capabilities on a particular portlet, like the calendar, he was not returned in the list of portlets to add to a page.

• Possible GPIB communication through interactive control of Visa, not with Labview

  Hello

  I have a communication problem with Labview with GPIB instruments (with functions of visa).

  I get:

  "Error 1073807298 occurred at the VISA opening

  Possible reasons:

  "VISA: (Hex 0xBFFF003E) failed to perform operation due to i/o error."

  However, it works with an interactive control visa and this is where I am confused!

  Here is my setup:

  -Labview 2011 assessment

  -VISA 5.1.2

  KUSB - 488B with the associated drivers (adapter USB to GPIB of Keithley)

  Because I can speak with my instruments in visaic, I guess the installation of drivers for the Keithley interface is ok.

  Trace IO NOR I see beeing of commands passed through Labview to VISA so that they "see" between them.

  I found a thread where someone had the same problem and its solution was downgrade to Labview 8.5.1, which is not possible for me.

  http://forums.NI.com/T5/instrument-control-GPIB-serial/Keithley-2700-driver-problems/TD-p/1474212/PA...

  You have an idea to solve this problem?

  Kind regards

  Baptist

  Here's a follow-up on this issue.

  I tried with Labview 32-bit on main machine: it works.

  The pleasure is that I have to use Labview 64-bit.

  So the ultimate solution is now to run a client and a server of visa on the machine: Labview 32 bit can directly access my resources GPIB, Labview 64-bit must go through the closure of the network.
