JSR 168 Under WebSphere?

If we develop portlets using JSR 168/ WSRP for Plumtree using WebSphere Studio and WebSphere (rather than WebLogic), should they work?
If there were problems that required a Plumtree fix, would such a fix be provided under normal support?
Thanks.

Portlet API: JSR 168 / 286 vs Vendor Extensions

Currently evaluating Websphere 5.1 vs WebLogic 8.1 Portal software.
It seems like both IBM and BEA push you towards using their Portal extensions as "value add" features. I am really interested in sticking to JSR 168 for portability.
Does anyone have any experience with these tools developing JSR 168? I would appreciate your observations about using the vendor extensions vs JSR 168 support in these tools. Please add any comments on other portal software you have had success with.
Any idea when will JSR 286 come out with final spec?

Consuming web services in a jsr 168 portlet best practices.

I am building portlets (jsr 168 api in Websphere Portal 6.0 using web service client of Rational). Now needed some suggestions on caching the web services data on the portlet. We have a number of portlets (somewhere around 4 or 5) on a portal page which basically rely on a single wsdl Lotus Domino Web Service.
Is there a way I can cache the data returned by webservice so that I dont make repeated calls to the webservice on every portlet request. Any best practices/ideas on how I could do avoid multiple web service calls would be appreciated ?

Interestingly, as it often happens with Oracle portal, this has started working without me doing anything special.
However, the session events my listener gets notified of are (logically, as this portlet works via WSRP) different from user sessions. The problem I'm trying to solve now is that logging off (in SSO) doesn't lead to those sessions being destroyed. They only get destroyed after timeout specified in my web.xml (<session-config><session-timeout>30</session-timeout></session-config>). On the other hand, when they do expire, the SSO session may still be active, in which case the user gets presented with the infamous "could not get markup" error message. The latter is unacceptable in our case, so we had to set session-timeout to a pretty high value.
So the question is, how can we track when the user logs off. We have found the portal.wwctx_sso_session$ and portal.WWLOG_ACTIVITY_LOG1$ (and ...2$) tables, but no documentation for them. However, the real problem with using those tables is that there's no way we could think of to match the portlet sessions with SSO sessions/actions listed in the tables. (Consider situation when someone logs in from two PCs.)
Any ideas?

JSR 168 APIs

Dear All,
We are trying to get content from IBM Websphere Portal v5.1 and display in our SAP portal . The content in IBM portal is stored in portlets . IBM recommended us to call their JSR 168 API's to just grab the content. We only want the content not the formatting. We cannot use URL iviews as their URL has not only the content but also a navigation panel , and we do not want the navigation panel.
I believe our Portal EP 7.0 can support JSR 168 compliant API from some of the information we found in SDN . But we are not able to locate the any how to guide on how to call such API from SAP whether from ABAP or Java we have no idea. Does anyone have something like a How to guide/ even sample code on how to call JSR 168 API or how can I proceed with this.
Best Rgds

hey you need to set up federated portal network(FPN) to establish this.i had done this before. i you only want webshpere portal content to be displayed in SAP EP, then implementing FPN alone wil do.if you want to dispay the content from SAP EP in IBM websphere then you need to do some coding in portal side to make your application jsr168 compliant

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

Subbu Allamaraju <[email protected]> wrote:
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.

How to deploy existing JSR-168 portlet in WLP 10.0?

I have a JSR-168 portlet packaged in a .war file and am trying to deploy in WLP 10.0. This seems like a common question that looks to be covered thoroughly for version 8.0 in the link:
[url http://dev2dev.bea.com/pub/a/2004/09/deployJava81sp3.html]
Those instructions no longer work, the tool is referencing classes that don't seem to exist in 10.0 and so it won't run.
I am currently attempting to move the pieces by hand into a new Workshop Web Project, but was hoping that by now there would be an easier way.
Any suggestions?

I stumbled across the answer after I had manually merged the portlet into an existing web project. It is actually pretty straight forward.
1. Right click on the web project, select import.
2. You will be presented with three options - war file, ear file, import.... The ware war file option is so tempting, but it is not what you want. Choose Import... to get a longer list of options.
3. Under "Other" you will see "Portlet from Archive".
This does exactly what I wanted, with the exception of the web.xml. The files are not merged, you can either skip it or overwrite it. Small price to pay for the convenience.

JSR-168 Consumer question

Hi,
I am new to plumtree portal but have used some other JSR-168 compliant portals such as exo and websphere. I want to reuse some of the portlets I created in plumtree portal. It seems installing the JSR-168 consumer on the portal server and remote server is a good way to achieve that.
Are there any concerns with installing the JSR-168 consumer on the portal server side? Any performance pennalties, compatibility issue etc? I am going to bring this up to our portal admin once I can get more information regarding it here.
Thanks

JSR-168/WSRP iViews

Hi,
I have the following doubts to be cleared.It would be of great help if someone knows abt these and revert back ASAP.
1) How many iViews currently exist? Is there a directory of available iViews?
2) Is SAP planning to provide today's iView functionality as JSR-168/WSRP portlets together with the new release (or later)?
3) Would it make sense to create JSR-168/WSRP portlets by reusing existing iViews? I.e. is the iView Java code customizable? Would that be a feasible approach in order to provide iView-like functionality through JSR-168 or WSRP portlets?
4)Any other alternatives to expose iView-like functionality through a non-SAP portal? If so, what would that look like?
Regards.....

Hi Christian,
1) This question is independent of WSRP/JSR, right? --> So, you mean, how many iViews in general.. There is no list published by SAP giving an overview of available iViews. However, you could get a little overview when checking out the business packages currently available offered by SAP and partners.
https://www.sdn.sap.com/sdn/contentportfolio.sdn
2) SAP is not planning to provide all the functionality in a JSR168/WSRP-compliant manner. SAP will support WSRP by the end of this year with the next NetWeaver release. However, this does not mean that the existing content will be available via WSRP. Some might be, but to which extent, cannot be said for sure now. JSR is intended to be supported next year, meaning that the NetWeaver Portal will be able to consume JSR168-compliant portlets, but not provide all the existing content in JSR168 format.
3) You are not allowed to modify iViews delivered by SAP. If you intend to modify iViews, which you created on your own, it depends on how much effort you want to spend on it and how long you can wait with your projects since both standards are not supported at the moment yet with the current SP releases.
4) Please a bit more specific about what you mean with iView-like functionality. In general, to leverage the full functionality of SAP iViews you always need the full NetWeaver Portal framework. There are some scenarios of how to integrate the SAP EP into the WebSphere Portal. Check out the docs here on SDN.
Kind regards,
Thomas

JSR-168 Portlets, Plumtree, and IIS

Is it possible to run JSR-168 portlets with Plumtree under IIS? Has anyone done it, and if so, how?

If you don't want to use the administration console to create channels based on the porltlets you deployed, you need to create a display profile fragment that create the channels and import using 'dpadmin'

JSR 168 Portlets with JSF Content

Is there any news on the possibility of achieving this.
Should I go ahead and do it myself using MyFaces and the Apache Portals JSF Bridge? (or try and leverage the WebSphere JSF tooling using the Apache Portals JSF Bridge)? Or use the Sun JSF-Portlet Bridge?
Thanks,
Don

Don,There is a JSR-168 / JSF portlet bridge that I tested on our portal a few months ago that worked pretty well. It required a lot of changes to the faces-config.xml file and the addition of a bridge jar. I think it also had some drawbacks in regards to the use of sub-views in a JSF page.If you are not tied to using JSR-168, a better solution might be the new JSF filter, which is similar to what we do with .NET Web controls. It allows JSF applications to run as portlets and refreshes the portlet using in-place-refresh (AJAX). This filter is simple to set up, well documented, and can be found at: http://portal.plumtree.com/portal/server.pt?space=CommunityPage&cached=true&parentname=CommunityPage&parentid=0&in_hi_userid=63776&control=SetCommunity&CommunityID=2758&PageID=5913under the name "Java Portlet Tools".Let me know which solution you are interested in. The JSF / JSR-168 bridge is available from Sun as development source code but you will probably want to use some of the helper classes that I wrote for it. These classes are not publically available, but I can send you a jar if that's what you need.Andy

Integration between portlets using JSR 168

I've developed 3 portlets but I want them talking with each other, in a way that is JSR 168 compliant.
For example, I have a search box portlet, where the user can only type search expressions, a search result portlet, where the user will see search results, and a search summary portlet, where the user will see statistics about search.
First question: how can I send data from one portlet to another? Is HttpSession a safe place to share data between portlets? Can I trust that all containers will create a single HttpSession per user?
Second question: how can one portlet force refresh of another, or even hide or show up another portlet?

Well it is a very smart question..
To be more precise i don't think it is been properly answered with
JSR 168 specification.
However,there few best practises followed in order to achieve it.
The idea of using HttpSession (PortletSession.getHttpSession() with Usage of AJAX) as you said it certainly one of the things which evryone would think.

Second Question:how can one portlet force refresh >of another, or even hide or show up another portlet?As discussed earlier Usage of AJAX / (And storing Common Credentials in a Bean which scoped to HttpSession) in the dependent portlet would be quite handy in the above discussed case.
Hope this might help :)

JSR 168 Portlet Filter

Hi ! I am trying to apply a filter to jsr 168 portlet in its web.xml file. Is it possible to add a filter like that to jsr 168 portlet. Any help will be very much appreciated.

if you are using websphere you can go outside og the portlet spec.

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.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye
