Jsr 168 and struts?

All,
I am doing some research on integrating struts framework with jsr168 framework. The reason for this is I do not put all the logic in the processAction method of the Portlet and I wanted to leverage the struts framework.
In struts the starting point is ActionServlet, whereas for a servlet the starting point should be the portlet class. How do we call ActionServlet from the portletServlet.
I guess I need to modify the RequestProcessor class method processActionForward method to return the path which should get invoked and feed in that path to the doView method of the portlet class.
Any ideas around this...??
Thanks,
Raghu

JSR 168 and Struts support sample error

I'm trying to get the sample webapp for JSR 168 and Struts support working with
WebLogic 8.1, and I'm having problems with the struts portlet. The other portlets
seem to work fine, but the Struts portlet gives the following error after clicking
"Save" on most of the forms:
Page Flow Error - Action Not Found
Page Flow: Global.app
Action: html-setters.do
Unable to find action html-setters.do.
That error appears in the browser. At the same time, the following exception
appears in the server window:
<Aug 18, 2003 4:34:12 PM EDT> <Error> <netui> <BEA-420012> <There was an error
while running a lifecycle stage :: Lifecycle: UIControl.render :: for the control
:: null ::.
com.bea.netuix.nf.UIControlException: For portlet [strutsPortlet], could not do
page flow lookup for the given action [html-setters.do] in the given PageFlow:
[struts/exercise-taglib].
This exception is followed by hundreds of lines of the following:
at com.bea.wlw.netui.pageflow.scoping.ScopedServletUtils.strutsLookup(ScopedServletUtils.java:363)
as well as several stack overflow errors.
I believe I have installed the JSR168 and Struts support package according to
the instructions, and have copied the required jars into the samples WEB-INF/lib
directory. I also have tried to write my own Struts application in a portlet,
and it gets the exact same errors when I try to submit a form to my actions.
Any insight would be much appreciated!
Thanks,
Patrick

Hi Brodi,
I am having the same problem as Patrick. The problem is not in the struts portlet,
but in the forms the portlet navigates to. After the struts portlet loads, I
am able to use the html:links and navigate through the pages. Though when I try
to submit a form I get the action not found error. For example the html-select
page has a form. This page loads fine, but when I hit the save button I get the
following error.
<Aug 25, 2003 11:00:00 AM EDT> <Error> <netui> <BEA-420012> <There was an error
while running a lifecycle stage :: Lifecycle: UIControl.render :: for the contro
l :: null ::.
com.bea.netuix.nf.UIControlException: For portlet [strutsPortlet], could not do
page flow lookup for the given action [html-select.do] in the given PageFlow:
struts/exercise-taglib].
The application appears to loose the struts context. It tries to find the localhost:7001/samples/html-select.do
action instead of localhost:7001/samples/struts/exercise-taglib/html-select.do
action. How do I keep the application from loosing context?
Thank you,
Karen

I've seen similar things happen when the module name is either not specified
correctly
in the StrutsContent element in the portlet, or when the module is misconfigured,
usually because of either a mising config file or a mis-named config
file.
Ensure that you have a the struts config file for the exercise-taglib
module in
WEB-INF, named jpf-struts-config-struts-exercise-taglib.xml.

SAP Enterpirse Portal Development standards (JSR 168 and JSR 286)

Hi
I am working on SAP Entperprise Portal Assessment. I heard SAP-EP not supporting JSR 168 and JSR 286 standards.
Can anyone please let me know what JSR 186 and JSR 286 standards are and impact in SAP development work.
Thanks everyone.

Hi Ravi,
SAP EP is definitely not supporting JSR 168.
The next release (Portal on NetWeaver 7.1) will support JSR 286.
You have to consider that the huge amount of SAPs standard portlets / iViews (addressing Knowledge Management, Employee Self Service, Business Intelligence, etc.) will not be implementations of JSR 286 but so called portal applications or Web Dynpro applications.
HTH,
Carsten

Support for JSR 168 and WSRP

Hi,
does SAP EP 7.0 supports JSR 168 and WSRP standards?
Regards,
Ladislav

Hi Ladislav,
Here are a few pointers that might answer your question:
- WSRP 1.0 is supported in NetWeaver 7.0 (see this [SAP Help Page|http://help.sap.com/saphelp_nw70/helpdata/en/43/23fb36cad10d23e10000000a1553f7/frameset.htm] for more information)
- JSR 168 support for Netweaver 7.0 has been discussed often but never confirmed in SAP documentation (check this thread for a recent SAP unofficial comment about its upcoming availability). However, NetWeaver CE 7.1 already supports JSR 168 (see this [SAP Help Page|http://help.sap.com/saphelp_nwce10/helpdata/en/44/5b96b37b6f4de1e10000000a1553f7/frameset.htm])
Hope this helps.

JSR-168 and Request Parameters

Hi!
I'm creating a portlet application; right now it only has one portlet in it. The landing page for my portlet (view mode) has the following form code:
    <FORM action="<portlet:renderURL/>">
        I'm thinking of a number between 1 and 10.<BR><BR>
        <I>What is it?</I>
        <INPUT name="<portlet:namespace/>number" type="text" size="10" />
        <INPUT name="submit" type="submit" value="Guess!!" />
    </FORM>When I submit this form, I see the parameter in my browser's URL window prefixed with the portlet namespace:
   http://host:port/portal/page/portal/portalpage?__ns36_5643_36_1_1_number=3&submit=Guess%21%21Here is how I'm trying to get the "number" parameter in the Java class associated with this jsp:
            String number = (response.getNamespace()+"number");I have also tried with
            String number = response.getParameter("number");In both cases the variable number gets assigned the null value.
How can I capture parameters sent by a form on a JSP page on the portlet's Java class?
I am developing this portlet application with JDeveloper 10.1.3.3.0.4157 and deploying to Oracle Application Server 10.1.2.0.2 with a wsrp-compliant container. Portlet is consumed in Oracle Portal 10.1.4.
Thank you for your response.

I'm sorry; I typed it wrong:
It's
String number = request.getParameter("number");However, if you're referring to the namespace, then the way I have on my book (Portlet Programming, Effectively Using the JSR-168 Standard, by Cameron McKenzie) is really
(response.getNamespace()+"number")

JSR 168 and Web Services For Remote Portlets

Hi,
I have recently joined SAP.In my previous work experience I have worked extensively on the Sun Java Portal Server and was curious about the following
1.Does SAP Enterprise Portal Server support JSR 168 compliant Portlets.
2.If yes the Question that naturally follows is:Can portlets(view Components)in a SAP Portal be remote enabled?In other words does SAP portal support WSRP standards.
3.If the SAP Enterprise Portal has implemented the JSR 168 specifications then how does the architecture seperate out the Portal engine from the Portlet Container.
In other words where does the actual wrapping from a HTTPServletRequest to a Portlet Request happen?
4.The JSR 168 specifications restricts the use of IFrames and many HTML tags in the fragments that are returned by the portlets running in the Portlet Container.Is this taken care of in SAP Enterprise Portal?
5.Can WebDynpro applications be embedded in a JSR 168 compliant portlet?
6.How is parity maintaned between portlet session HTTP session and the Applications session?
7.Does SAP Portal support deployment through a par model?
Thanks and Regards

I'd like to know the answer to this question as well. I wrote an email but didn't receive any response. So i guess JSR 168 isn't supported yet?

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.
Check:

JSR 168 and UIX.

Hi,
Iam a newbie working on an JSR 168 app that makes an existing portlets as JSR 168 compatible. The portlets was orginaly developed usign the JPDK api and to incorporate standards we are making it as JSR 168 compatible.
We used the UIX pages as the front end for showing portlet content. Is it possible to leverage the existing UIX pages using the JSR 168 API. For Rendering the UIX content we used the JPDK classes like the RenderManager , PortletContainerRenderer etc.
As i understand JSR 168 provides the RenderRequest which represents the request sent to the portlet to handle a render. Can this RenderRequest be used to display UIX pages.
Just wanted to know a couple of things.
a) JPDK providers RenderManager , PortletContainerRenderer etc are there equivalents in the JSR 168 API
b) Difference between the RenderRequest of the JSR and the PorletRenderRequest class .
At a brief Iam looking for an equivalents of in the JSR 168 API which can accomplish this.
Thanks
Mouli

Hi Mouli,
In case of JPDK always you will get single request i.e., HttpServletRequest from the portlet.you can get the PortletRenderRequest from HttpServletRequest.
Way to get PortletRenderRequest from HttpServletRequest :
===========================================
PortletRenderRequest portletRenderRequest=(PortletRenderRequest)oHttpServletRequest.getAttribute("oracle.portal.PortletRenderRequest");
[NOTE : you need to import the following class.
import oracle.portal.provider.v2.render.PortletRenderRequest;]
In case of JSR 168 generally you will get two kinds of request ie., RenderRequest & ActionRequest.Where PortletRequest is the parent interface for this two interfaces.
For Ex.whenever the portlets first time loaded on portalpage the portlet will get RenderRequest & it will create its own portlet markup.When ever you perform any operation in any portlet then it will have ActionRequest & remaining portlets will have RenderRequest.
Please feel free to ask anything related to portal technology..Let me know if i specified anything wrong.....

What is the difference between JSR 168 portlets and WSRP portlets?

What is the difference between JSR 168 portlets and WSRP portlets?

Here is the difference between JSR168 and WSRP:
The WSRP specification does not make any statements as to implemention. Java's portlet specification, JSR 168, and WSRP are not competing technologies. JSR 168 may be used to define a portlet, and WSRP may be used to define a portlet's operations to remote containers. JSR 168 portlets and WSRP may be used together to define a portlet and to provide remote operations. Similarly, .NET portlets may be created for use with WSRP. Interoperability between JSR 168 and .NET WSRP implementations has been demonstrated

WSRP/JSR-168 for production?

Maybe I'm missing something, but from my little research on the use of WSRP/JSR-168 within Portal, all indications are this is not ready for production use. Meaning, if I use JDeveloper (or some other tool) I cannot deploy production quality Portlets based on these standards within Portal 10g (9.0.4). Is this correct, or did I miss something?
Given this, my only choice is to use the JPDK if I wish to develop Java based portlets.
Thanks...
Dean

Hi all,
Even i am also looking for if any body has consumed the JSR168 portlet on
OracleAs Portal 10g Release 2.
I have found some article where it is mentioned that
Production Support for JSR 168 and WSRP
Once upgraded to Oracle Portal 10.1.4, a repository only upgrade on top of OracleAS 10.1.2.0.2, your portal version provides production support for building and consuming standards-based portlets. Oracle portal provides a Java Portlet Wizard within Oracle JDeveloper to build JSR 168 portlets and publish those portlet to Oracle's container or any portlet standards container. You can then consume JSR 168 portlet with Oracle Portal through WSRP. Oracle Portal also supports consuming any portlet through WSRP as well as JPDK portlets.

JSR 168 / WSRP support in EP

Hi All,
As I am getting no clear reply, I would like to ask the SDN-ers for help regarding the JSR 168 and WSRP support by the Portal.
Can anyone tell me whether any of the above standards is supported by the NW'04 or NW'04s - and if not (i guess this is the case for JSR 168) - for which NW release it is planned ?
I will appreciate your quick reply
Regards
Maciek

Yeah, but I was hoping for some more up-to-date news... This one is dated august'05. I have a presentation saying that BOTH WSRP and JSR168 will be available as of 04's ("Project Paris").
We do have the WSRP - but it seems that in the meantime the JSR is gone...

JSR 168 support on production environment??

Hello Oracle people,
when are you going to support JSR168 portlets in you Oracle Portal?? Where is the money customers pay you for working? not enough? What do we do with this piece of closed source box you gave us if you can not be ahead many other open source (free) products? Can you stand the pace? you say "we support standards"... and I see you are falling behind.

you should be demanded because of the way you assure support of the JSR168 in your executive brochures... Any layer out there who can help?
Look this question and how Oracle answers:
Does Oracle Portal support JSR 168 and WSRP?
Oracle has been an active member of the standards bodies and been instrumental in the process of defining these portal interoperability standards:
* JSR-168: Defines how Java developers should write portlets using standard APIs.
* OASIS WSRP (Web Services for Remote Portlets): Defines the communication protocol between a portal application and the remote portlet./li>
Oracle fully supports the JSR 168 portlet specification. You can develop JSR 168 portlets using the Java Portlet Wizard, a JDeveloper plug-in. You can also deploy JSR 168 portlets to Oracle's or any other vendor's JSR 168 Java Portlet Container. Portlets deployed to Oracle's container are exposed to portals through WSRP, and can be registered against any portal vendor's WSRP compliant portal. The current version of Oracle Portal (Oracle Portal 10g Release 2 (10.1.2)) does not support WSRP, but you can register and test standard portlets using the OracleAS Portal Developer's Preview for Portlet Standards or the hosted WSRP compliant portal on http://portalstandards.oracle.com. You find additional information about Oracle and Portal standards on http://portalstandards.oracle.com.
When there is a simple answer: NO we do not support the JSR168 in Oracle Portal. We do a lot of other things... see this and that. But sadly our Oracle Portal does not support it, you can test a preview version but if it crashes its your problem (we proudly do very expensive closed source :).

JSR-168 Support

Do we have any plans to resume support for JSR-168 portlets to extend integration with other portal platforms besides WCI and WLP?

WSRP & JSR-168

Hello!
I'm trying to declare my portlets as remote and connect to them.
I have JSR-168 compliant portlets and I created remote portlets to them on a consumer.
But every time I submit a form the portal reverts to the initual state instead of processing my request.
I was also wondering if WebLogic processes only URLs created using the netui library?
thank in advance,
Vica

Developing Portals using JSR Compiant API and struts

Hi,
I am using Oracle AP Portal server 10.1.4 for development and all the existing portals are developed using Oracle PL/SQL. We have to convert all of them into JSR 168 Compliant (JPS API ) portlets using struts framework.
Could you provide us ideas or code snippets or sample applications?
It will be appreciated your responses as soon.
Thanks
Suren

I may end up having to do that, but I'm trying to keep my solution set as it is as I apply a print layout using tiles to each of the reports and I would like to keep things that way if I can.
I just noticed something interesting that I had not seen before, and that is in the PDF there is text rendered for the tiles tag <tiles:getAsString name="title" /> which tells me that the HttpURLConnection is getting the tiles attributes, but where it is failing is on the <tiles:insert attribute="body" /> tag. That at least narrows the problem down to the tiles:insert line specifically and not tiles overall.
