I also see that JDev reports these objects do not exist in edit mode, but if you compile/run your portlet it should execute without problems.
Or do you get an error when you try to run "view.jsp" ?
If so, please post the stack trace.

URL generation - Https and JSR 168

We have some JSR 168 complaint portlets that are working fine under http. However,
when we switch to https (with a webserver front-end), the edit button functionality
generates incorrect urls. It tries to use http and then append port 443. These
urls do not work with the web server front-end.
I know all urls for JPF portlets etc are controlled through the url-template-config.xml
file, but it seems that the JSR 168 portlets do not use this file. Any idea what
these portlets use and what configuration change I could make to resolve this
issue?
Thanks
Kunal

Hi Subbu -
I have modified the template to use relative paths - maybe that will solve my
issue. Here is my modified template.
Thanks

Hi Kunal,
In WLP, all portlets rely on url-templates-config.xml to create URLs.
The edit button is independent of the type of the portlet you are using.
For Java portlets, could you make sure you have the following snippet
in
this file:
<java-portlet-url-templates>
<url-template-ref type="action" name="portlet-default"/>
<url-template-ref type="secure-action" name="portlet-default"/>
<url-template-ref type="resource" name="portlet-default"/>
<url-template-ref type="secure-resource" name="portlet-default"/>
</java-portlet-url-templates>
</url-template-config>
where the name of the template should be mapped to one of the templates
defined in this file.
If you still face issues with this, please post the templates specified
in this file so that I can take a look. Also, let me know if you are
using GA or SP2.

WSRP (jsr-168) portlets no edit/help buttons appear

Hi,
I have some jsr-168 portlets that I wrote that work on other portal software (like uPortal). They have both help and edit buttons (specified in the portlet.xml and handlers written into the portlet code) and you can click them and see both the help and edit modes of the portlets. However, when I put these portlets on Oracle Portal (10.1.2/10.1.4), the edit/help (or personalize) buttons don't show up. I even tried to use the sample portlets from sun, like the BookmarkPortlet, etc, and they have the same problem.
Any ideas?
Thanks,
-Mike M.

Hi,
I dont see anything obvisouly wrong with what you are doing. I suspect the var attribute though. Can you try out this sample
">view</a><br>
<a href="
<portlet:renderURL windowState="maximized" portletMode="help"/>">help</a><br>
Thanks,
Sharmila

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.

Upload file in Portlet (JSR-168) with library commons-FileUpdate

hi All,
I have write portlet (JSR 168) "UpToFile.java" for upload a file with the Commons-FileUpload 1.1.1 but when deploy in the Oracle Portal the file is not upload, because the variable isMultipart is false:
UPToFile.ProcessAction(...) :
boolean isMultipart = PortletFileUpload.isMultipartContent(request);
(Utility method that determines whether the request contains multipart content.)
view.jsp:
<FORM ACTION="<portlet:actionURL/>" METHOD="POST" enctype="multipart/form-data" >
upload file: <INPUT TYPE="file" NAME="file-upload" SIZE="20">
<INPUT TYPE="SUBMIT" value="upload" >
</FORM>
I do not understand because "isMultipart" is "false".
Tanks.
EDIT: sorry, now work. :)

Weblogic Portal 10.3.5 - JSR-168 Portlet resize at runtime by the users

One of the requirement I'm trying to develop in WLP 10.3.5 for JSR-168 Portlet is to give the end user the flexibilty to resize (Just like we can do in Iframe in IE) it in runtime. Is it possible to do this ?
Any helpful link / pointers are welcome.

Hi,
Could someone pls explain which cache is used to cache portlet content and in which form the content is cached?

Integration of JSR-168 portlet into Portal - Complete Guide

Hi there,
the CE 7.1 is described to be compatible with JSR-168 portlets.
Our Company has developed a JSR-168 portlet which comes as a WAR-File
which can be easily included in other application server and portals (WebShpere, Apache).
But integration in SAP Netweaver fails - I am missing a complete documentation
which describes me the necessary steps to integrate a JSR-168 portlet application
into the SAP Application Server and also how to integrate the GUI into a View of the NW portal.
PLEASE HELP ME!!!
Things I tried - Things I failed:
- Imported a EAR-File into Developement Studio and tried to add it to Server
-> Message "EAR Project: ... should have the SAP specific facet in order EAR to be built."
- Deployement via "Deployement Tool" of Netweaver 2.0 (2004s) worked
and I was able to start app but no integration into NW portal view was possible
(Where is the deployement tool in NW 7.1 CE?!?!?)
- I wanted to create a PAR-File by a WAR-File but dont know how?
- I did not find any iView template which is for my portlet type.
Did anyone out there has the same probs or could help me....
Thanks on advance,
Andi-)

Hi Markus,
There is no complete guide for integration of JSR-168 portlets into a portal; however Diyan is correct.
In a nutshell, once you have deployed your portlet, you use GPAL technology in the SAP NetWeaver Portal of CE to create an iView wrapper in the PCD. All of this done by a portal content admin in the Portal Content Studio. Your deployed portet should be displayed in the "Portlets" repository within the Portal Catalog of the Portal Content Studio.
For conceptual and how-to documentation, refer to the following SAP Help Portal links:
- Generic Portal Application Layer (GPAL) Repositories: http://help.sap.com/saphelp_nwce10/helpdata/en/44/5e93dc35624ddee10000000a1553f7/frameset.htm

JSR 168 portlet based web service throwing an error ......

Hi All,
I am quite new to this whole new fusion concept.We are trying to build some web center based applications.
I have downloaded jdev11g(Studio Edition Version 11.1.1.0.0)technolgy preview version and started following the pdf documentation that comes with it to build the web center based applications.
As given in the docummentation i have built a JSR 168 Java Portlet through the wizard in Jdeveloper.
2:Created a java bean to store the portlet information,added some business logic to the portlet.
3:Deployed the portlet application in the preconfigured OC4J that is shipped with the jdeveloper.
4:When i test the webservice from within the http analyzer in jdeveloper by invoking the web service i get a response like this:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/><env:Body><env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>no serializer is registered for (interface javax.xml.soap.SOAPElement, {urn:oasis:names:tc:wsrp:v2:types}getPortletPropertyDescriptionResponse)</faultstring><faultactor/></env:Fault></env:Body></env:Envelope>
5:If i then try to register the WSRP Portlet producer to my deployed application i get the the 500 status error which states that it cannot register the portlet as it could not connect to the host because the application is not deployed correctly or the producer container is not running or that the host is beyond a firewall.
It cannot be that it cannot connect to the host because of firewall ,the pre configured oc4j is also running which leaves the option of the application not being deployed correctly in the server.!!
While i try to register the portlet the preconfigured oc4j log displays the error in point 4:
Any help would be great as i have no clue what went wrong in the deployment because everything is so wizard driven...
Looking for some urgent help...as we are in the process of building prototypes for the customer!!!

Hi user,
I think it best not to use the 11g preview versions anymore. To build WebCenter applications, you should use the last 10g version, which is 10.1.3.4. 11g Production has superseded the preview versions, and in that there is no webcenter support, as everything is now migrated towards weblogic.
So please try to follow your tutorial in 10g.

JSR 168 portlets packaging question

Hello,
I have a bunch of Java (JSR 168, using Spring MVC) portlets (PortletOne, PortletTwo...PortletN) that I created as individual Portal Web projects and are contained in a Portal EAR project. This portal EAR is my deployment unit and also consists of another Portal Web project (Assembly.war) that holds a app.portal file where I plan to assemble all these Java portlets and use it to create a desktop. The reason for having all the individual portlets in web projects of their own is to be able to export them as a unit and use it elsewhere either as a shared library or package it within another EAR file as the need arises.
my application.xml looks somewhat 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 I cannot reference the context definitions and the controllers for the portlets defined in each of these portlet WAR files (PortletOne, PortletTwo,...) from the common web project that holds the app.portal file in Assembly.war. I tried to define a custom classloader structure in weblogic-application.xml and put the assembly war file at a lower level but the app even fails to deploy with IllegalAccessError as soon as a context for each of the war files is registered by the hot deploy process. Moreover, when I deploy the EAR file, the portlets defined in each of the WAR files do not appear in the Resources library when viewed from the Portal Administration console.
Any suggestions how to assemble these individual portlets into a common web project, while still keeping them packaged within the same EAR file? Alternate approaches are welcome too.
I have already considered deploying these portlet WAR files as Weblogic J2EE shared libraries. But with this approach, the overall application response time is very slow in spite of exhausting all tuning options and also cannot pre-compile JSPs in the shared libraries.
Is importing the JSR-168 portlets using the import utility as WSRP portlets a viable option? Will I be able to share session variables across portlets, fire and handle events and be able to pre-compile the JSP in idividual portlets?
Edited by: shyam6190 on Aug 13, 2009 1:25 PM

Hello,
Perhaps the multiple nested classloaders involved with the shared libraries approach is slowing it down- if that is the case, it would be hard to fix.
Using WSRP should work for you; there is a bit more complexity but if you have relatively simple portlets, use the correct JSR168 tags and methods (or the Spring bridge does), it shouldn't be too hard to get to work. The IDE may be able to help you with that; you can create a new portlet of type "remote portlet" in your aggregated webapp, and a wizard will walk you through the steps. If you use local proxy mode, the portlet's individual WSDL URL will be the URL to each portlet's webapp on localhost.
The WSRP configuration can also be done dynamically in the Portal Admin Tools, and even using a specialized JSR168 import tool, but both of these options would only create database instances of portals and portlets in your aggregating webapp. This would be fine if your aggregated EAR never needs to move to a different deployment environment, but if you require portability of the EAR to another environment it complicates packaging, as database information is also required. If you happen to be using WLP version 10.3, I believe there is a bug which prevents the specialized JSR168 import tool from working, but the tool is documented here:
http://download.oracle.com/docs/cd/E13155_01/wlp/docs103/prodOps/deployment.html#wp1047337
Since all the WSDL URLs will point only to the localhost, when you package the aggregated WAR file it should deploy properly to any servers. Information about the local proxy mode, which should improve performance for your configuration, is described here:
http://download.oracle.com/docs/cd/E13155_01/wlp/docs103/federation/Chap-Best_Practices.html#wp1010714
Hope this helps!

Problems with JSR 168 Portlets

Hi!, I�m working with JSR 168 Portlets and after successfully deploying it into the portal (6.2) I�m not able to get any content. I�ve already made a war (I couldn�t make the studio 5u1, (PB 2) simulate it :( ), and it seems to be correctly deployed inside appsrv (7). I placed some JSP�s and HTML�s and they are available from a browser but not from the portal. The first error I got was Channel time out but then I managed to get Content not Available. It seems that the portal is not able to reach the JSP�s but I�m not sure. Is there any restriction about folders with this or just by deploying the war makes everything? Is it necessary to set the files inside the portal folder? I�ve read the manuals many times and I can�t find a suitable tutorial (the only I got is one to make a provider or a channel :( ), nor a detaliled how to. I�ll thank any advice.
Cheers , Pablo.

Deploying JSR-168 compliant Portlets on an Enterprise Portal

Hello,
This is Sitaram Nanduri.We r new to NetWeaver Developer Studio.We have to write JSR-168 compliant Portlets that will be deployed on NetWeaver Enterprise Portal.Please guide me how can i deploy Portlets in NWDS EP.Thank u.

Hi,
-Users are not developers, they are end-users managers and business analists and they want to create their own operations dashboard.
-Just imagine that our main application can produce portlets that display the weather information of just one city (I know the portlets could have a preference that may allow users change the city they want to see). the main appliction can assamble a war'ed jsr-168 portlet that displays the weather of that city, that war'ed jsr-168 portlet could also be put in the deployment path of weblogic, our app can do that without problems, end-users don't have any idea of what is going on behind the scenes.
-Imagine for example that we want to see one and only one city weather information in each portlet, so managers can assamble a dashboard of cities wheather portlets. One manager may want to see the weather of just two cities (two portlets), a second manager four cities (four portlets) and so on, any number of portlets.
-In the above scenario I still don't see how I can add to each manager portal any number of jsr-168 portlets without pre-configuring an specific number of federated portlets in the portal.
Thank you!

Apache Struts Bridge for JSR-168 Portlet

Hello,
I am trying to call a struts application from a JSR-168 Portlet.
But I am not getting this class "oracle.webdb.wsrp.server.PortletApplicationImpl"
Which is required for this.
Can anyone, tell me, where to find this class.
Thanks

I was able to find that class by downloading the Oracle Portlet Container 10.1.2.0.2 and following the instructions for extracting it into my OC4J. When you do that it will give you a file called ${OC4J_HOME}/shared-lib/oracle.wsrp/1.0/wsrp-container.jar. That jar file contains the class you need.
Oracle Portlet Container 10.1.2.0.2: http://download.oracle.com/otndocs/tech/ias/portal/files/portlet-container.zip

(Why) do I need a JSR-168 Portlet container?

Probably I'm missing something essential here, but whey do I need a JSR-168 portlet container? Suppose I'm using Tapestry 4 to write my JSR-168 compliant portlets, can they be consumed "directly" by a WSRP Portal server?

Because:
"A portlet container runs portlets and provides them with the required runtime"
"environment. A portlet container contains portlets and manages their lifecycle. "
"It also provides persistent storage for portlet preferences. A portlet container"
"receives requests from the portal to execute requests on the portlets hosted by it."
"A portlet container is not responsible for aggregating the content produced by the"
"portlets. It is the responsibility of the portal to handle the aggregation."

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.
