How to do interportlet communication in JSR 286 Portlet

HI,
We are using webcentre portlet producer appliaction and creating JSr 286 portlets. Using Jdeveloper 11.1.8.1 .
Now we have two portlets one is search and another is search result.
After the seacrh is clicked DAO should get called and search result should get refreshed with the search result.
PLease let me know how can we do this ?
Thanx in Advance.

Hi ,
You can refer below links to achieve interportlet communication.

Exception when deploying a JSR 286 portlet into WebLogic+WebCenter

I get the following exception when deploying a JSR 286 portlet into WebLogic:
"<19-ene-2010 13H32' CET> <Error> <oracle.portlet.server.containerimpl.PortletApplicationImpl> <BEA-000000> <Error al procesar el archivo "/WEB-INF/portlet.xml" en la lÝnea 6 columna 68.
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'portlet-app'"
The error message is in spanish. It means:
"Error processing the file "/WEB-INF/portlet.xml at line 6 column 68"
The portlet.xml of my portlet seems to be correct and I've deployed it in other portal servers. So I don't understand the error message.
This is the portlet.xml of my portlet (eclipse XML validator said it was a valid XML)

Support of JSR 168 and JSR 286 portlets

Hi,
As far as I know there is no direct support for JSR 168 compliant portlets in the SAP portal. Remote portlets can be consumed using WSRP. I was wondering whether the SAP portal will provide direct support for JSR 168 or even JSR 286 portlets in future releases?
Regards,
Kevin

Hi Kevin,
Long time ago SAP promised to implement JSR 168. Nowadays, you don't find much official documentation stating SAP portal is JSR168 compliant.
SAP introduced the Federated Portal Network (Consumer and Producer portals), also with WSRP support.

Inter Portlet Communication for JSR 168 Portlets

Hi,
I want to invoke one JSR168 Portlet from another and also pass parameters between the two.I did the same using Events for Oracle Portlets.
I would like to know how to do the same when I build JSR 168 Portlets.
Also Pls let me know where I can get documentation which describes all the possible options that I can try out on JSR168 Portlets
Regards
Yash

Hello Yash,
The current version of the specifications does not support Parameter and Events that allow you to create portlet 2 portlet communication using OracleAS Portal framework.
If the reusability of the parameter is not a major requirement of your application you can simply use URL parameters and this will authorize you implement that.

Migration of WCI portlets into JSR 286 portlets

Hello,
We have portlets developed in struts2.0 and registered in WCI container. Now we want to move or converts those portlets into JSR 286 and then we want to register those portlets into
Oracle WebCenter.
Question: Can we go for Oracle's PDK or JSR 286?
Thanks.

How to refresh JSR 286 Portlet from managed bean?

Hi,
I am using jdev 11.1.1.5, I have created a Portlet Producer Application, this application contains ADF TABLE with command link inside and the partial submit set to false.
I want to refresh the portlet when in Portal Application from within the action of the command link.
The idea behind this scenario is that the same command link have 2 behavior:
-open popup window
- reload the ADF Table and changing the "value" for it
If I change the partial submit to true, the reload works fine but the popup does not appear
If I change the partial submit to false, the popup appears but the reload of the table does not happen.
Thank you in advance
Emile

This question should be moved to the WebCenter forum: WebCenter Portal
You have a commandLink that opens a popup in your consuming application and on the same time you also want to refresh the portlet?
Why not adding a partialTrigger to the portlet that listens to the commandLink?

Load property file in init(PortletConfig) method of JSR 286 portlet

I store my configuration in .properties file. Now I want to load this file only once, so I decided to load it in init(poerletConfig) method. But now I'm confused to where to put this file, so it can be loaded in this method. I'm using following code:
Properties properties = new Properties();
try {
properties.load(new FileInputStream("which_path_to_give_here")); // not sure where to put property file and how/which path to give here?
} catch (IOException e) {
System.out.println(e.getMessage());
}

Friend i think you are trying to reinvent the wheel again...
To my knowledge liferay provides a utility class for FileUpload by default.
Guess U need to add portlet-ear.jar along with the application you programme.
Hope you could have seen admin portlet already where we would upload company logo.. hope you remeber tht....
I've Posted the code behind(ActionClass) it in the below post
http://forum.java.sun.com/thread.jspa?threadID=5160308&messageID=9610263#9610263
it would be great if you can make use of StrutsPortlet class provided by liferay and configure your porlet.xml accordingly & then write an PortletAction class & then create its action mapping in struts-config.xml.
and the reason why i'm stressing with that approach was sometimes The FileUpload Components may not be compatible different Portlet Containers
Hope that might help :)
and a small advice liferay does have their devoloper zone where you have user communities.Im sure you might get a better reply from their side too.

Interportlet Communication

Hi,
Have a query with regards to the following.
Appreciate if anyone could advise or correct my understanding:
For the current project implementation, there are the following portlets from various vendors, using various implementations:
1) A main portal, with a login portlet implemented using BEA workshop (BeeHive Apache NETUI)
2) a shopping portlet (product A) implemented using MVC
3) a checkout portlet (product B) implemented using JSR 168
A typical user process will be to login, shop and checkout as in the above order.
The 3 portlets above will need to communicate with each other.
(a) Interportlet communication
BEA allows these methods:
(i) event handlers
(ii) backing files
(iii) refresh?
Question 1: Are the above methods vendor-specific to BEA only?
Note: Assume all 3 portlets are deployed locally, i.e. with not as remote portlets.
Question 2: If yes, how can the login portlet "talk" to the other 2 portlets?
Given that checkout portlet is implemented using JSR 168, does this mean portlet session is the only way of sharing information?
Question 3: Can event handlers be used for IPC for this scenario, since its the most recommended way by BEA to implement this.
Understand event handlers are defined in .portlet file. Is this correct?
Question 4: Can both shopping and checkout portlet be "imported" to Workshop for development?
Will both of them have .portlet file? If yes, then I would think event handler method can be used?
Appreciate any advice or feedback.
Thanks.

Hi Barry,
What do you mean "it doesn't work"? What kind of errors are you seeing? Also, you only specified the file name (data.vi) when opening a VI reference. Try specifying the whole path to the VI. Also, you might want to make sure you are able to ping your other computer from the start (to see if this is a LabVIEW issue or a network issue).
Hope this helps,

How to debug jsr 168 portlet in jdeveloper 10.1.3.4

Does anyone know how to locally debug a jsr 168 portlet in jdeveloper 10.1.3.4.
When I click on run it asked for a start page so I supply the view.jsp page.
The following error occurs on the page:
500 Internal Server Error
java.lang.NullPointerException at helloworld.html._view._jspService(_view.java:61) [helloworld/html/view.jsp] at com.orionserver[Oracle Containers for J2EE 10g (10.1.3.4.0) ].http.OrionHttpJspPage.service(OrionHttpJspPage.java:59) at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:462) at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:594) at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:518) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:713) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:370) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.HttpRequestHandler.doProcessRequest(HttpRequestHandler.java:871) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:453) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.HttpRequestHandler.serveOneRequest(HttpRequestHandler.java:221) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:122) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:111) at oracle.oc4j.network.ServerSocketReadHandler$SafeRunnable.run(ServerSocketReadHandler.java:260) at oracle.oc4j.network.ServerSocketAcceptHandler.procClientSocket(ServerSocketAcceptHandler.java:234) at oracle.oc4j.network.ServerSocketAcceptHandler.access$700(ServerSocketAcceptHandler.java:29) at oracle.oc4j.network.ServerSocketAcceptHandler$AcceptHandlerHorse.run(ServerSocketAcceptHandler.java:879) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.4.0) ].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:298) at java.lang.Thread.run(Thread.java:595)
This is the first jsr 168 portlet I have tried.
Previously we have been created portlets using the Oracle PDK. Those portlets are easy to debug because the wizard creates an index.jsp page for the start page.
If anyone can provide some insight to my issue it would be greatly appreciated.
Thanks,

Is this a portlet you built from scratch using the JSR 168 APIs, or is this a JSF Portlet using the JSF Portlet Bridge. If the latter, you can debug your JSF application. If the former, you can do remote debugging (let me know if you need information on this).
Hope this helps,
Peter

Ok now I get your requirement.
you cant achieve this - how one receiver channel can put in two location if you dont have a dynamic configuration defined i.e Adapter specific attributes.
easy way - involve IR mapping
else
have a adapter module to define your dynamic configuration.

Set the dynamic directory/file name etc for your receiver adapter.

How to deploy a JSR-168 Portlet in Weblogic?

I am running WLS 8.1 with the advanced JSR-168 support installed (not yet running
SP2). I have a JSR-168 portlet war that I had been testing in the JSR-168 reference
implementation (pluto). Can someone please point me to the instructions on how
to now import my portlet war into Workshop so that I can add it to my Weblogic
portal?
Thanks!
-David

You cannot simply "deploy" a JSR 168 portlet into Weblogic using a WAR file in
my experience. This is what I did to achieve deployment of a JSR 168 portlet in
BEA WLS 8.1SP2:
* File | New | Portlet | Java Portlet
* Just type in the name of your view class name when asked for it.
This creates a "YourAppName.portlet" file, which I believe Bea requires for any
Portlet in order to make it available for use in their portals.
* Add your files (*.jar, *.java *.jsp, etc).
* Modify WEB-INF/portlet.xml to include all required descriptor elements that
you have in your WAR file (keep in mind that there is only one portlet.xml for
all portlets in a single web application)
I was unable to use redirects for some reason, but it worked fine with include.

How to enable DDE communication and Network DDE DSDM on windows 7

How to enable DDE communication and Network DDE DSDM on windows 7

Hi,
For Network DDE to function, NetDDE.EXE needs to be installed and running on both machines before attempting to conduct a Network DDE conversation. NetDDE.exe is a Windows Service system file that is used to communicate the shared dynamic data exchange used
by Network DDE. It has no graphical user interface (it runs as a background Windows service).
