RSS Portlet

Hi,
I am currently using Weblogic 7.0. Does weblogic provide a RSS portlet for Content
Syndication on the web. The "WorldNews" porltet available with SamplePortal of
Bea Weblogic. throws an error on accessing that particular page(on which the World
News Porltet resides). Any pointers why this error could be occuring would be
helpful.
The error that is thrown at the server is
javax.servlet.ServletException: String index out of range: -1
at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java:450)
and many more lines..
Also if anyone has worked on building an RSS Portlet ...could you please let me
how to go about it.
Would really appreciate a prompt reply.
Thanks,
Ankita

There was once a Oracle By Example with the RSS example in Portal on OTN.
I cannot find it now but try searching OTN.

RSS portlet Error!

Hi,
I am using the RSSPortlet 1.0 downloaded from Sun's site. I have deployed it in Open Portlet Container but its giving out an error!!
Invalid URL, please re-enter
Invalid XML: Error on line 4: The element type "meta" must be terminated by the matching end-tag "</meta>".
This error comes when I am entering a new feed URL and saving in the edit page. Again, this error comes in the view page as well while reading the first rss feed.
I have tried using well formated xml file as well as I have tested the URLs which I am entering.
Can anyone suggest anything? Has anyone used the RSS portlet?
Thanks.
Tanmoy

Hi Lasanthajn,
Is this the same setting for other web app ?
Did you put future date and month intentionally ? Sun, January 2016 ?
Did you try putting http://lankacnews.com/sinhala/?feed=rss2 ?
Let us know your results, thanks

RSS Portlet ... rendering markup?

I installed the RSS reader portlet (by the way, it works in 6.1) and noticed that html markup isn't being rendered as html markup.
For example, if the rss has a link, the user actually sees the brackets, br tags, etc.
Anyone found an easy fix for this?
Also on my wish list was fixing the proxy settings and allowing it to ignore SSL errors...

AAARG. I'm starting to hate this RSS portlet.
So I have a forums software (phpbb3), that I'm pulling in RSS feeds from.
So I can put javascript into a forum post, and it will be propertly html escaped in the forum and in the feed....
it looks like this in the forum and in the rss feed:
<script>alert("hello world")</script> <-- those are supposed to be "& l t ;" and "&g t ;" instead of the actual angle brackets
however, in the RSS portlet, you actually see the hello world alert, and when you view source you see the angle brackets and not the < >...
sigh ... any ideas?
I"m not sure what the solution should be here...if I turn on html encoding in reader.jsp, then every tag gets encoded, even br...so its not really a good solution
Edited by: Joel Collins on Feb 23, 2009 9:10 AM
i switched up some things in the RSS feed for my forum so it double-escaped the script tags. all's well that ends well.

How to Implement a portlet to display data from RSS Feed ?

RSS portlet -- multiple instances w/ different contentURLs?

The documentation of the RSS sample portlet (http://edocs.bea.com/workshop/docs81/doc/en/core/index.html)
describes how you can use this portlet in your own portal application. Furthermore,
it claims that it is possible to use different instances of the RSS portlet with
different contentURLs. I am unable to figure out how I can set the contentURL
as an instance property. It appears that it can only be globally changed for the
entire portlet itself, meaning that all instances of this portlet have the same
content.
Any hints appreciated.
Jan

i can only assume that it is a portlet preference. you can go in through the admin
tools and set them or if the portlet hase an 'edit' button they should be editable
through there for the end user.

Web portlet installation

hi,
how can i install a web-portlet?
in detail: i want to install the rss-portlet from knowledge exchange.
thanks,
matthias

Hi Matthias,
By web portlet, i hope you are talking about JPDK portlets. If this is the case, please have a look at the following document: http://download-uk.oracle.com/docs/cd/B14099_01/portal.1012/b14134/pdg_java.htm section 5.4.2.5
For other portlet related queries, please have a look at the Portal Developers Guide (the above document)
thanks,

Support For JSR 168 PortletSession Ojbect

Recently, I've written a JSR 168 portlet and attempted to use the PortletSession object to persist some information between user requests. The portlet puts properties on the PortletSession (String and object properties), but the JSP page can not see them. Within the JSP I've tried accessing the properties with the JSP session and by casting the session to a PortletSession. Either way, it doesn't work.
I reviewed the sample Google and RSS portlets and they are not using PortletSession but persisting only String data in render parameters. I've read the JSR 168 specification and you should be able to do what I'm doing and use the PortletSession. Anyone have any ideas?

How are you getting the session? Are you using the defineObject tags and then getting the portletSession from renderRequest?
If you like, send an example of the code in the jsp page & I can try it out.

RSS Reader Ajax Portlet for Workshop 9.2

Hi,
is there any available example of RSS Reader Portlet with Ajax support for Workshop 9.2?
Any help is well accepted,
thanks,
Ben

Ben,
With the weblogic portal 9.2 you can find all the JSP but this time Bea has not given the JPF code.Jsp code is available there.The path will be
\WebContent\portlets\rssreader\*.jsp
Create EAR project
Create Portal project with groupspace enabled
Go to merged view of the weblogic workshop
Right click the portlets folder and choose copy to project
Hope this time you will get the sample code :-)

RSS/XML Feed Portlet

Under 4.5WS we had a number of portlets that were fed directly from internet XML feeds, such as moreover. Having upgraded to G6 it would appear that we can no longer do this in the same way.
I have been reading various posts referring to sample RSS feed portlets but cannot appear to find them either in these discussions or in the CodeSample area.
Can anybody provide a clearer pointer where we can get some sample/shared code to do this as we would rather not start from scratch. Ideally code that allowed for multiple feeds into the same portlet.
Thanks,
Ross Ellard

Thank you Eric. Flattery will get you everywhere. ;-)
<marketing>Maybe we can discuss this further at BEAWorld. Are you going? If so, stop by our booth.</marketing>
If your time frame is more urgent, then let's talk on the phone soon. You have my number, I'm sure.
I like the idea of a general XML/Web crawler that uses XSTL to convert to some intermediate format and then crawls it into ALUI. That could work with almost any data source because you could go DB->XML+XST->Crawler->ALUI. If we insist upon the intermediate format being standard RSS (RDF), then we actually kill two birds with one stone. We just implement an RSS crawler and then tell clients of the service that if their XML is not in RDF, then they must provide an XST that transforms their XML to RDF and then we're good . . . .
I already have some nice RDF parsing code in C# -- you cool with that for our language/platform?
Best,

RSS feed based on omni portlet ?

We have a project that needs to create an XML Publisher portlet ..
We need to develop a RSS feed.
can we use omni portlet for this aim ?
Is there any complete documents here or anyone can give more details on this?
Thanks for your help...

I have worked on a portal project in the past that created an RSS feed by creating a pl/sql function to generate the XML. The function is then invoked through mod_plsql. I believe the developer of the feed downloaded the original source from the portal website somewhere.

GroupSpace RSS Reader Portlet Bug - Null Titles

I have a GroupSpace community that utilizes the out-of-box GS RSS Reader portlet. Currently, I am encountering an issue with displayed feed channels/entries: the titles are null. In the tree view (the left pane), the titles for entries are blank. I can click on the icons to navigate the tree. In the details view (the right pane), titles are displayed as "null" and authors are blank. I cannot click on the titles to view the channel/entry.
I checked the content repository in the the WebLogic Portal Admin Console and the titles are displayed correctly there. I didn't notice anything in the server logs, not sure what else I could check.

They are all RSS 2.0, which is supported. And yes, all the entries and channels have titles. They just don't show up in the list in the "Title" column or in the tree view. I did notice that the title does appear correctly in header section of the details view though.
Other RSS Readers display the feeds/channels properly. Several months (5+) ago, this portlet was displaying them correctly. I'm not sure what changed. I don't think the code to display the portlet has changed. There have been many changes to other portlets in the portal, but the portlet resides on its own page so I'm not sure what could be interfering with it. I did have to modify the groupspace callback class to address an issue with communities not being added to the database with dvt enabled.
I'm certain the the portlet is consuming the XML files correctly as I can see the content in the WLP content repository.

Consume RSS feed in Portlet

Hi all,
I am looking to display RSS feeds in Portlet. I am aware of use of OmniPortlet to achieve the same. I want to look at some other open source standard options to go about doing the same.
Can some please throw some ideas for displaying RSS feeds without using OmniPortlet?
Your help would be greatly appreciated.
Dipal

i tried to consume RSS feed through the portlet, but i am getting the following error:
Utility.pingWebClipTestPage: Loading of Web Clipping Provider failed: HTTP Response code = 500
After giving the proxyinfo in both webclipping and omniportlet provider.xml files.
thanks

Where can I find and Download RSS feeds/portlets?

Where can I find and Download RSS feeds/portlets? Any help would be greatly appreciated. Thanks.

Terrel,
If you mean the Screaming Media portlets (Not free) you can get them from your Plumtree Account Manager.
If your looking to get some source code (C#) for reference on how to do this, you can email me at [email protected]

World News Portlet - RSS Content Syndication

Hi,
The world news porltet given with the Sample Portal of Bea weblogic 7.0 throws
an error of "StringIndexOutOfBound -1"
Could anyone give any pointers as to what could be the reason for this error.
Could it be the problem with the proxy ? if yes then any pointers to how it could

How to add portlets to the task flow page

I am using WebCenter space and I want space users to be able to put the portlets into their group space pages.
All the portlets are under portlet folder in the catalog. However, our requirement was to have a custom folders.
For example, the user administration portlets have to be in something like "user administration" folder and report portlets have to be in something like "report" folder.
By "extending WebCenter Spaces" White Paper, I can create a custom folders and then I can put custom task flows. However, it doesn't say anything about the portlets. I opened SR with Oracle but so far I don't have the answer from Oracle.
So I tried to add portlet into task flow pages after registering the portlet producers. However, it gives me the error portlet unavailable. Do I need additional steps to do this? I need help...

Thank you.
However it is not showing in the catalog.
I used the WSRP producer connection name as provider and id from the portlet.xml file.
rss is my WSRP producer connection name from EM and the id is numeric in my portlet.xml file.
I can see the folder but I cannot see anything inside of the folder.
