Discussion Sample Portlets for WC Interaction

Hi,
Environment -
ALUI 6.5 Portal , Oracle Wiki & Blog Server and Oracle Discussion ( Jive ) Servers + WCI Sample Porltes - all on the same Weblogic 10gR3 server.
I am trying to consume the WCI ( Aqualogic Interaction ) Sample Portlets for Wiki&BLogs and Discussion available @
http://download.oracle.com/otndocs/tech/webcenter/interaction/files/wci_scvs_portlets_wikiblog.zip
http://download.oracle.com/otndocs/tech/webcenter/interaction/files/wci_scvs_portlets_discussions.zip
I could get the Wiki & Blog Portlets successfully running , but the Discussion sample gives me the following message ( POST configuration )
On the configuration (preference) for the portlet , I give the IP:Port and ViewMode=Forums
URL = http://<I.P>:PORT      
Category ID
ForumID
Thread ID
Message ID
Page Size      
View Mode =     Forums
Template
On submitting the initial setup I get the response -
"The service does not appear to be responding. Please enter a valid url."
However my URL Pointing to the Webapplicaiton /WCDiscussions is correct .
Any one who has got it working ??
-regards
reju

I am also having problems with the Discussions sample portlet, my scenario is somewhat similar: created a sample portal with Workshop for WebLogic 10.3 and used the embedded WebLogic Server 10g3 to run the portal. The Wiki & Blog portlets work fine, but the Discussions portlet prompts:
The category null is not valid. Please enter a valid category or leave blank. If I try to enter a valid category number, I get the same error with the category number I entered (e.g. "The category 2 is not valid"). The discussion server is running and I can access the forums directly via a web browser without problems.
Is this a problem with the sample portlet? Has anyone successfully used it?

  • How to deploy the Wikis, Blogs and Discussions Sample Portlets ?

    Hi all,
    I'm trying to deploy Wikis, Blogs and Discussions Sample Portlets located at
    http://www.oracle.com/technology/products/webcenter/release11_demos.html (the demo at the bottom).
    I've successfully, deployed the portlet to WebCenter Portlet service using JDeveloper 11.1.1.2.0.
    And I've successfully register the porlet proivder in 11g Portal.
    However, when I added the portlet to a new page, it returns error
    "Error: Could not get markup. The cookie or session is invalid or there is a runtime exception".
    I've recreated the page and refresh the screen. But still got the error.
    Anyone know what's going wrong?
    Thanks!
    Larry

    I found that the sample code has hard coded the WikiRemoteService to be
    http://localhost:7001/owc_wiki/services/WikiRemoteService
    Our environment use another port. After chaning the port number, both interfaces of Wiki and Blog (I just added the two portlets in to a Portal 11g Page) could be loaded. Also, I can create blog, blog entry, add comment via the Blog interface.
    However, Wiki portlet seems not working properly. The request I submit via the interface (e.g. show wiki) returns me error
    "The service does not appear to be responding. Please enter a valid url."
    Anybody has idea?
    Thanks.

    When you run the program, the system displays the following basic list with a the page header defined in the program:
    You can trigger the AT LINE-SELECTION event by double-clicking a line. The system sets the status TEST and deactivates the function code PICK. The status TEST contains function codes FC1 to FC5. These are assigned to pushbuttons in the application toolbar. The page header of the detail list depends on the status.
    Here, double-clicking a line no longer triggers an event. However, there is now an application toolbar containing five user-defined pushbuttons. You can use these to trigger the AT USER-COMMAND event. The CASE statement contains a different reaction for each pushbutton.
    For each interactive event, the system decreases the SY-LSIND system field by one, thus canceling out the automatic increase. All detail lists now have the same level as the basic list and thus overwrite it. While the detail list is being created, SY-LSIND still has the value 1.

  • Discussion Forum Portlet not working on standalone OC4J

    Hi,
    I'm testing the Discussion Forum Portlet.
    I imported the portlet to jedeveloper in order to make changes to it.
    I deployed it to a standalone OC4J (without doing any changes yet) and succesfully registered a provider, but when I put the portlet to a Portal-Page I get the following error:
    "Unable to perform the operation: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-33001: Cannot find the configuration file config\common\bc4j.xcfg in the classpath"
    Deploying to the OC4J_Portal Instance on the Application Server and
    registering the provider with this URL is working.
    I'm using Portal 10.1.2.0.2.
    I tested with OC4J standalone versions 9.0.4.0.0 and 10.1.2.0.2.
    What could cause the fact that the Portlet isn't working when it is deployed to an standalone OC4J?
    Regards,
    Mario

    I'd recommend asking the Portal/Portlet people -- I think exposure to this sample will be required to give you any assistance.
    One thing to be aware of though is that the libraries for BC4J (which this sample seems to use based on that error) aren't installed by default with OC4J standalone. Whereas for OracleAS 10.1.2 they are. So that might be something to chase down.

  • Error JBO-26080 with Discussion Forum portlet

    Hi,
    I'm getting an error with the discussion forum portlet.
    This is one way I found to reproduce this problem:
    - reply to a post in a forum
    - do a search that should include the post added before in the result
    - you should get this error
    Unable to perform the operation: JBO-26080: Error while selecting entity for ThreadSearchEntityObject
    Is this a known problem? Does anybody knows a fix/workaround?
    Thanks in advance
    Bye
    Lorenzo

    Hi Pedro,
    I found the portlet on this page
    http://www.oracle.com/technology/products/ias/portal/point_downloads.html
    the one called "OracleAS Discussion Forum Portlet".
    On this same page this forum is suggested to report problems.
    I think this problem is due to some BC4J error, maybe a quick fix/workaround is possible, but I do not know this technology.
    In the next day I'll try anyway to check the source, but I was also interested to know if somebody else has the same problem so to exclude the option of some installation/configuration problem of my deploy.
    Thanks again
    Bye
    Lorenzo

  • Where can I find a sample ERD for a University

    Hello.
    I have to develop a program in C# that manages details about the students, taxes, courses, etc and prints some reports.
    It's for my license degree.
    The programming part is not that hard but the task that is killing me is designing the database because I have poor experience with data modeling.
    I don't have access to my university's database so I need to make one myself..and the teachers won't help..
    I tried to make a diagram but I realised that I cannot do it, I got stuck.
    An university database can get extremely complex and it's hard to make .. so I wonder if any of you know where can I find a sample ERD for a University. I need one as complete as possible.
    Any help is appreciated..

    Unfortunately due to the quality of most of the homework questions on these forums I believe you when you say the teachers are no help. You should still discuss it with them and make clear you are not learning what they are supposed to be teaching.

    The top hit looks like a good start.

  • Discussion Forum Portlet on RAC Environment

    Hi
    I have installed Discussion Forum Portlet but I am seeing the following error intermittently:
    Unable to perform the operation: JBO-26041: Failed to post data to database during "Insert": SQL Statement "BEGIN INSERT INTO MESSAGE_CLOB(ID,AUTHOR_ID,MESSAGE_DATE,CONTENT,THREAD_ID) VALUES (:1,:2,:3,:4,:5) RETURNING ID INTO :6; END;".
    I think the problem is because we have our database in a RAC environment where our Portal schema is. I am not sure how to specify the same details in the bc4j.xcfg file. The following are the details that I have in the bc4j.xcfg:
    <ConnectionDefinition name="df">
    <ENTRY name="JDBC_PORT" value="1521"/>
    <ENTRY name="ConnectionType" value="JDBC"/>
    <ENTRY name="HOSTNAME" value="hamcheese.corp.ihop.com"/>
    <ENTRY name="DeployPassword" value="true"/>
    <ENTRY name="user" value="df"/>
    <ENTRY name="ConnectionName" value="df"/>
    <ENTRY name="SID" value="asdev1"/>
    <ENTRY name="password" value="df"/>
    <ENTRY name="JdbcDriver" value="oracle.jdbc.driver.OracleDriver"/>
    <ENTRY name="ORACLE_JDBC_TYPE" value="thin"/>
    </ConnectionDefinition>
    How can I specify the two hostnames in this file?
    Please let me know.
    Thanks
    Hari

    Hi Hari,
    I am not sure how this would work, but i think you could try posting the issue on the Database / JDBC forums, specifying the issue as
    How to specify connect details for a RAC m/c in the Datasource file.
    You might get some answers there.
    thanks,

  • Editing the discussion forum portlet

    Hi,
    I've just deployed the discussion forum portlet from portal center, and am using it in a portal. But, how can I remove the big Oracle Logo that is displaying in the portlet?
    Best regards
    Eva Svensson

    Hi Evan,
    Are you talking about OracleAS Provider for Jive Forums?
    If you are, then you can remove the logo by going to:
    htdocs/launchLink.jsp
    and modify the table tag which has a reference to the logo(images/logo.gif)
    thanks,
    Harsha

  • Portlets for e-mail integration?

    During OOW2000, Oracle-staff giving presentations mentioned the development of portlets for integration with e-mail systems (like Lotus Notes and Microsoft Exchange).
    Technical staff at the campgrounds said that this functionality was close to release (November/December 2000 was mentioned as a probable time of release).
    1) Is this type of functionality still under development?
    2) When will this type of functionality be available?
    3) Which e-mail systems will be integrated?
