Themes and JSR168 Portlets

Hi,
How can I get the information about current themes from JSR168 Portlet classes.
All Theme.class methods have ProviderContext as parameters. PortletContext is not the same.
Joanna

This is a known problem with the preview release, and a fix will be
included in SP2.

Is there anyone who can answer this? Has anyone tried using Visitor tools with
JSR168? Did it work? I am anxious to find out ! Thanks

When accessing the visitor tools with a JSR168 portlet on a page, the

Any workarounds? Thanks

JSR168 Portlet Exception with Oracle OC4J and Spring

JSR168 Portlet Exception with Oracle OC4J and Spring
I’m having a problem with accessing a Spring JSR168 Portlet when deployed on Oracle OC4J. I have created a very simple portlet that just renders simple jsp page. I created two versions. One using GenricPortlet and one using org.springframework.web.portlet.mvc.AbstractContro ller. The non-Spring portlet deploys and runs as expected. The Spring portlet deploys but throws the following exception

2007-11-05 08:23:44.085 WARNING An internal error has occurred in method getMarkup()
I have managed to deploy and run the Spring portlet using Sun App Server and Sun Portlet container with no problems which leads me to believe my Spring setup is correct.
I also have managed to run the Spring pets portlet example on Sun App Server and Sun Portlet container with no problems. But again it fails on Oracle with the same problem.
To deploy on Oracle I ran the oracle wsrp jar against my EAR. As far as I can tell it has not corrupted any of the Spring setup in the web.xml.
The version are as follows
Oracle Portal 10.1.4 running on OAS 10.1.2
calling the portlet using WSRP v1.
The portlet is running on standalone OC4J 10.1.3.3 with Oracle portlet container 10.1.3.2. On Windows Spring 2.0.6.
Any ideas? Thanks Paul

Was an answer ever found? I am currently experiencing the same issue.

How to expose JSR168 portlets from existing JSF webapp?

Hi all,
I have a web application with JSF components, and a set of JSP pages that use these components. In WEB-INF, I also have a standard portlet.xml which describes what JSP page to expose for the declared portlet(s).
Is there any administrative interface in the WebLogic Portal that would automatically detect these portlets as soon as I deploy the webapp, so that I can display them ? My idea is that as soon as this webapp with the portlet.xml is deployed, my portlets should be added to the list of available portlets somewhere. Is that so with the WebLogic portal ? Thanks very much for your feedback.
P.S: I am using WebLogic Portal 10.0
Regards,
Angel

I'm not sure I understand your question. It sounds like you have JSF (faces) components and JSP pages; do you also have JSR168 portlets? The WEB-INF/portlet.xml file should have nothing to do with JSF / JSP pages; it is used only to declare JSR168 portlets.
To try and answer your question though, if you have JSR168 portlets listed in WEB-INF/portlet.xml, these portlets should show up in the administrative tools when the webapp deploys.

JSR168 portlet packaging?

From the JSR168 spec, (which is similar to how other portals seem to behave
with their proprietary APIs), a JSR168 portlet application appears to be a
WAR with a portlet.xml and web.xml conforming to the requirements of the
spec, that can then be installed in any portal.
From my superficial knowledge based on skimming the WL8.1 portal docs
recently, WL portlet development appears to be done within a Portal WAR such
that the portlet(s) are just components of the portal war itself.
How are these two supposed to work together in the WLP env? Say I develop a
couple JSR168 portlets in my own Java environment (emacs :-) and then WAR
them up and install them into Jetspeed-2 and another 168 compliant portal
when available (eg, IBM's 5.something). I believe those would accept my
portlet WAR and keep them in that WAR and just reference them from their
Portals. How would WL8.1.x handle such development (outside of Workshop/WL)
and deployment to a WL8.1.x portal? Do I have to merge my JSR168 based
portlet WAR (and thus a web.xml and portlet.xml merge) into the Portal WAR
(eg, if I want to ship a script to deploy my portlet WAR into an existing
WL8.1 portal?) or will WL8.1.x be able to reference a Portlet WAR outside of
a Portal WAR?
TIA - a confused potential portlet developer...

I agree with what Joe said...
BTW, I (and I assume Joe) think JSR168 is a good thing - and it's great that
WLP has the first prototype of it out there - don't get me wrong, I like it,
I'd just prefer if it were easier to deploy to given portlets coming in from
multiple sources being added into an existing portal. From Joe's case, he
probably doesn't want to have to merge the portlet.xml files. From my case
as a supplier of portlets, I'd rather not have to have to create different
install tools/docs/procedures for my customers for each portal vendor now
that I can have standard portlets based on JSR168...

You can always import any arbitrary webapp using the WLW as a portalproject
I'm not sure that solves my problem or the one ISV was talking about(which
I assume is the same).
I am not talking about importing a webapp (containing portlets or nto) and
making it be my portal.
- Assume I'm already developing a portal with some in-house developed
portlets.
- I want to get 3 JSR168 portlets from SAP (just picked a random vendorout
of the air) and add them to my portal.
- I want to get 2 JSR168 portlets from Siebel (ditto)
- And I need one Domino portlet from that other 3 letter vendor (ditto)
- Each of those vendors is likely to build JSR168 portlets that can be
installed/used in any JSR168 compliant portal, so they can stop buildingall
the various per-vendor proprietary API portlets.
- Each of those vendors needs to package up their portlets for
shipping/install.
- Given that JSR168 describes the Web App layout for packaging a portlet,
each of those vendors is likely to package their portlets up in a WAR.
- Some JSR168 compliant portals (I believe) will be able to just install
those WARs and use them as is from the Portal WAR and drop them on pages.
- WLP 8.1 appears to require that I unpack/extract those WARs and mergethe
portlet.xml and contents of each of those WARs with my existing Portal WAR
that I want to add those portlets to. Tell me why this is better?
To your earlier comments made here:
The pitfall of this approach is that webapps depend on each other towork correctly
Well yeah, I expect my portal to depend on my portlets - of course.
which is against the spirit of webapps.I disagree - EARs depend on the WARs within them. Cooperating WARs can
depend on each other too.
A deployer should be able to deploy/undeploy any webapp withoutaffecting the functionality of other
webapps - which would be case in the model you describe.Of course, if you remove a portlet that a portal depends on, I wouldexpect
it to break .
In addition, there are security issues that the deployer must be awareof.
Of course. That's the case with any J2EE deployment no matter how many
EARs/WARs you're deployiing.

Joe,
You can always import any arbitrary webapp using the WLW as a portal
project, and during that process you'll have the opportunity to
automatically update the descriptors (and also adding the correct jar
files). There is no need to hand-merge descriptors unless you want to.

That would make sense if one were developing all their own portlets
for
their portals.
But I (and most people I know) as a customer, that needs to aggregate
portlets from multiple (possibly many) 3rd parties, such as the big 4
application vendors, am going to need to know how those standardJSR168
portlets work and are configured so that I can hand-merge them into my
company's portal?
As an end user it doesn't really help me that much that I can developmy
own
portlets to JSR168. The whole point of JSR168 is that portlet vendorsthat
build portlets for others to install into their portals will be able
to
build one set of portlets that can then be installed in any compliant
portal. This limitation seems to prevent that from beingcommonplace/useful
(given how few people are going to know how to do such merges - theyjust
want to install 3rd party portlets and drop them on pages). I reallyhope
Workshop provides a user friendly way to integrate such 3rd party
JSR168
portlets or WLP will be missing the whole point of having such astandard in
the first place. I agree with the ISV that started this
conversation -
please provide a means for me to install 3rd party portlets withouthaving
to hand-merge XML configuration files.

Jsr168 portlet issue

Hi,
1. I developped two jsr168 portlet and deployed them to java portlet container successfully, but the status of one is always not loaded, against, the status of the other is loaded, do you why?
2. i want to add the portlet which its status is loaded to my page, but I cann't find it in the portal builder. Do you know where is it or how to find it or how to add a jsr168 portlet to a page after deploying it?
thanks very much
jason

Thanks very much for your reply.
because i don't want to use the JDeveloper to help me to develop and deploy the jsr168 compliant portlet on oracleAS10g Portal, so my question is that how to add my jsr168 portlet to a page when i deploy it successfully?
In fact, I already finish developping the jsr168 portlet and deploy it to java portlet container on oralceAS10g successfully. but i cann't find it in the portal builder, so i don't know how to add it to my page. can you give me more information about it in detail? I don't think i can get enough information from the developer's guild pdf document, i read it, but i still cann't figure out my problem.
thanks again

Thanks Brad !!!
It works...
earlier I had entitlements set only on Employee Portal and Calendar in the tree structure Community_repository > Calendar > EmployeePortal > Calendar.
It didnt work and throwed that error.
After your suggestion I set entitlements on groupware.calendar.appointment to create, view, update, delete and instantiate to true.
It worked, thanks for your help.

Floating JSR168 Portlets

Is the floating window state available to JSR168 portlets? If it is where to set
it? Thanks

This is what I heard from tech support regarding floating JSR168 portlets!
"I opened CR135056 for your case. I will let you know if I get response from our
engineer."
So, I guess we just have to wait and pray ! Thanks

Hi,
We are also attempting to use a floating portlet for help mode for non
JSR-168 portlets but that does not work either. We currently have an
open support case with BEA with this since 13th April and thus far no
fix so i would not expect to see a fix in the short term as it seems
floating portlets simply dont work !.

How to debug JSR168 portlets

Hi,
Is there a way to debug the jsr168 portlets from Jdeveloper, possibly using remote debugging feature? If yes, appreciate step-by-step instruction on this.
I have posted a query related to remote debugging here:
Remote Debugging (Jdev 10.1.3 to AS 10.1.3)
Thanks,
Pandian.

I'm not sure I understand your question. It sounds like you have JSF (faces) components and JSP pages; do you also have JSR168 portlets? The WEB-INF/portlet.xml file should have nothing to do with JSF / JSP pages; it is used only to declare JSR168 portlets.
To try and answer your question though, if you have JSR168 portlets listed in WEB-INF/portlet.xml, these portlets should show up in the administrative tools when the webapp deploys.

Edit mode in JSR168 Portlet

Hi all,
I m using Portal version 10.1.4 and developing JSR168 Portlet using JDeveloper 10.1.2.1.0 (Build 1913).
There is a edit mode in my portlet and i have done entry for this mode in portlet.xml and also implemented doEdit() method.
inside doEdit() method i have also written response.setContentType("text/html");
Successfully deployed the .ear and also registered the WSDL url.
But when i click on the Personalize link of the portlet then a page comes with a message
Error: Could not get markup. The cookie or session is invalid or there is a runtime exception.
And the error in wsrp_default_island_1\application.txt is
javax.portlet.PortletModeException: Portlet mode "edit" is not allowed in current context
at oracle.webdb.wsrp.server.PortletURLImpl.setPortletMode(Unknown Source)
Could any one tell me where i m doing wrong.
help will be appreciated..
Thnx

Hi Harsha,
Actually there is a problem with setPortletMode method of PortletURL.
When i use
PortletURL portletURL=renderResponse.createActionURL();
portletURL.setPortletMode(PortletMode.EDIT); (Although it is not required , but in case if situation occurs like if i want to change the mode then it will fail)
In this case if i click on Personalize link then it is throwing an exception.
Is it bug with Oracle Portal , i don't know....
When i comment that code then every thing is working perfectly for me
and the required jsp is rendering in Edit mode of the Portlet.
Comments ans Suggestions are welcome at 24*7 :-)
Thnx

Hide and show portlets

Hello all,
I have created two forms and two reports and added them in a page as 4 portlets like this...
FORM1 REPORT1
FORM2(Hidden) REPORT2(Hidden)
---------------------------------------------------------By default Form2 and Report2 are hidden..
If I click the link on Report1...
Form2 and Report2 should be visible....
How can i acheive this..
I hope someone suggest me a good solution..
Thanks a lot in advance..
Regards,
Paappu.

I do not think it is advisable to use page properties to hide and show portlets on them on user interaction. This assumes that we can do it by changing the display properties of those portlets on Page.
The reason is this: If I am a user of your portal and visited one such page, I would see Form1 and Report1 on the page.
Let us say, I clicked on some link you are planning, and then I started seeing Form2 and Report2 on that same page.
However at the same time, you also visited on the same page right after I had clicked on that link. Then you will also see Form2 and Report2. And so the state of the page will be changed for all users after the first user's action.
Is it actually what you would intend to do? that different users will see different pages based on who has visited the page before them?
that is why I would not recommend it. Hope that helps.

Problem deploying JSR168 portlets; Tomcat, Win2003

Dear All,
Am having some problems deploying the JSR168 portlets on Tomcat 4.1 and Win2003.
This is on Windows, and I have to manually deploy it per the instructions...
So far I__
1. Exploded the .war and added ptjsr168 to pthome.xml per the sparse installation pdf;
2. stopped tomcat, deleted the cache (contents of the work directory), restarted.
3. verified that the application appears in the work directory
but get the error,
/PtPortletContainer/portlet/RssPortlet/mode/view
descriptionThe requested resource (/PtPortletContainer/) is not available.
...when I try to browse there to get the correct URL tp paste into the remote server, something like:
http://portlets.mycustomer.com:8080/ptjsr168/
The extension to this in the web service is, by default:
/PtPortletContainer/portlet/RssPortlet/mode/view
I may be typing the URL wrong, for all I know. Something simple.
Any ideas?
Cheers,
Rob

You can verify whether your portlet works correctly by testing it on OpenPortal Portlet Container(https://portlet-container.dev.java.net). Or if you think the issue is with Pluto Portal I would recommend posting your issue on the Pluto Portal mail alias.

Deploy jsr168 portlet in weblogic

Hi,
I'm developing a jsr168 portlet that I would like to be able to deploy in the Weblogic Portal (among others).
The problem is, after much searching, that I can't figure out how to do it.
In Websphere I just deploy the .war file through the portal administration web interface and away I go.
In jetspeed2 I just drop the .war file in the deploy folder and it gets deployed.
Is there anything similar for Weblogic?
I've currently got 8.1 SP4 installed.
I've seen and even tried the portletPreparer tool but I can't get it to work (dependencies on bea classes that I can't find).
Any help or tips on how to deploy a portlet in a .war file would be greatly appreciated.
Cheers,
Eric

Hi,
Generally while creating a jar file for deplyong a EJB on an App Server, create a folder called META-INF and copy all your xml files to this folder
this command could be part of your build.xml if ur using ant
mkdir build build\META-INF
copy *.xml build\META-INF
Then compile ur java files and then create the required jar or ear file for deployment.

Forums and Chats portlets

Hi
Are there any forums and chat portlets that I can use with
Oracle9iAS Portal?.

Arnaud,
3 options
1. Buy the Partner's portlets
2. Download the Collaborative Components from OTN
http://otn.oracle.com/software/tech/java/servlets/content.html
and integrate them with Portal
3. portalstudio.oracle.com -> Knowledge Exchange. Not sure about polls, but there is a discussion forum portlet (among others)
Hi
Before buying Portal, i tried Portal Online, and i could see Forums and Polls. I can't find them in portal r2. Where have they gone ? Are they commercial partner's portlets I'll have to buy ???
regards
A.

Writing a JSR168 portlet WITHOUT using Jdeveloper or "wizards"

I have a JSR168 portlet that is built using Maven (http://maven.apache.org/ if you don't know what that is).
It deploys and operates perfectly well into a portlet container such as Pluto (the standard, reference container from Apache).
Pluto supplies a Maven plugin, that takes the vanilla web.xml and other configuration e.g. portlet.xml and adds the necessary configuration to run the portlet in the container. I believe there is an Ant plugin that does exactly the same thing.
It adds the following conf to teh web.xml;
<servlet>
<servlet-name>my-portlet-name</servlet-name>
<servlet-class>org.apache.pluto.core.PortletServlet</servlet-class>
<init-param>
<param-name>portlet-name</param-name>
<param-value>my-portlet-name</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>my-portlet-name</servlet-name>
<url-pattern>/PlutoInvoker/my-portlet-name</url-pattern>
</servlet-mapping>
This is the "magic" that glues my portlet to the portlet container.
What I wish to know, is how to make my JSR168 portlet deploy into Oracle Portal 10g without EVER using JDeveloper. What is the 'magic' I have to apply to my web.xml or portlet.xml or other configuration that will men I can deploy my portlet war into the app server and make it talk turkey with the portal container. I can cope with just having a customised web.xml that I have to copy into the WAR file if need be ... if I could find some guidance what should be in that file.
It seems that every search I've done in google or though the doco we have here starts with "Start Jdeveloper and select XXX in the portlet wizard".
I do not use Jdeveloper and nor will I. I will continue to build my Java code in a correct fashion, i.e. on the command line with my standard build tools that don't involve the IDE. Don't get me wrong, I use an IDE, but one should never be mandated. In my book, "wizards" are about the worst imaginable way to get any programming task completed.

Hi Marcel
With respect, it's patently obvious that we know how to develop a portlet without Jdeveloper, because if you read the message you would have been able to discern that this is the way we are accustomed to doing it, and it's faster, easier and more portable that way. I've been doing J2EE development since the first version of the spec and well before there was an Oracle implementation of it.
You don't actually need an EAR file, as a WAR will suffice and the dcmctl command-line utility can supply everything else in its arguments (like, context-path and the like), and it allows each WAR artifact to be deployed in different times, i.e. when they are built on the integration server. I find EAR files usually too heavyweight especially as I rarely write EJBs, as opposed to using e.g. Spring.
Using the web browser is not an option for automated deployment and acceptance testing from an integration build server.
Configuring the portal side of things looks decidedly a different matter and I've not found anyway to do it from the command line, it demands the browser, which is a let-down.
It's terribly disappointing the paucity of information about automation of deployment as opposed to the positively verdant amount of presentations, tutorials and documentation that assumes top-to-bottom Oracle tooling and environment and browser-based configuration. Even where it's actually possible Oracle doesn't seem to want to tell people about it or do as I believe they should, which is regard this form of deployment and configuration as the default way to teach developers how to use their products. None of this helps build and deploy to Oracle products using test-driven development, continuous integration, and automated acceptance testing, all of which are usually regarded as essential parts of a modern developers toolkit by the best minds in the business.
So after we're left alone to discover how to do this by ourselves for a month you can forgive my disappointment at being lectured like I was some neophyte who doesn't know how to make a WAR file with textedit.

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
