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.

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.

My Problem is that all went fine until i want to register the Forum Portlet. I get WWC-43176 Error: The provider URL specified may be wrong or the provider is not running, but i did not belive this error message.
Have anyone sucessfully done this on this iAS Version? When yes how did you get this to work.
Any help will be nice.
thanks
Peter

Hi Peter,
Have you tried searching this forum for a similar issue. If i am not wrong there a lot of threads discussing the installation issues of the discussion forum portlet. I will let you know if i come across any information.

Discussion Forum Portlet Security Flaws

Can someone from Oracle answer me on the following:
- Will there be another release of that porlet soon?
- And if so, will the next release fix the security vulnerabilities that have been reported (such as: http://www.sec-consult.com/248.html)
- Will Oracle eventually support the Discussion Forum Portlet so that it can be used in a production environment?
If so, when?
thanks

Can THIS Discussion Forum Portlet be downloaded/installed in my own Portal?

I jsut downloaded/installed the "Discussion Forum" portlet and was wondering if this one we are using here can be also downloaded etc? If so, where/how? THANKS!!!

Yes, this is a classpath issue.
The pdkjava.jar and ptlshare.jar files don't seem to be in the classpath. Are you sure you've followed the steps provided in the Installing the Integration Portlets document? You find it in the ZIP file when you download the discussion forum portlet.
The relevant sections:
Deploying Using Oracle Enterprise Manager (OEM)
===============================================
In the Library Paths section, you can add a library. To add a library path, click Add Another Row. Add the following jar files:
../../../../portal/jlib/pdkjava.
../../../../portal/jlib/ptlshare.jar
../../../../webcache/jlib/jawc.jar
../../jazn.jarManually Deploying to a Stand-Alone OC4J Instance
=================================================
Add, if not available, the following dependent library references to the $OC4J_HOME/j2ee/home/config/application.xml file (make sure these entries are not already existing):
These entries should be child tags of <orion-application ...> tag.

JAVA Discussion Forum Portlet of craig Laurent

Hi all,
I downloaded the Java Discussion Forum portlet which is developed by laurent from Oracle Portal Integration Solutions site.
But I have some issues in using this portlet.
As per the instructions I have installed the portlet successfully in both OCS V1 and OCS V2.
1) But in OCS V1 when creating a Topic or reply to a Topic the record is creating with a TIMESTAMP of 3 Hrs less than the actual time. I understand he is using CURRENT_TIMESTAMP to capture the time. When I checked by create a record in a dummy table with capturing TIMESTAMP directly in SQL*PLUS, correct time is capturing without any difference. This is the problem I am facing with OCS V1.
2) In OCS V2 the problem I am facing is something tedious. When tried to create a Topic the record is not at all creating in the database, at the sametime no error message is also occuring.
Can anybody please...... help me to sorted out these issues.
Thanks & Regards,
Durai.

Hi,
I am also having a problem in using Java Discussion Forum Portlet. I have deployed the portlet successfully in OCS V2(Portal Version 9.0.2.3.0B). But when I am creating a topic it is not creating a record in the database. I can be able to create forum, but I couldn't create a topic and reply topic. Should I need to apply any Patch.
The same portlet which I deployed in OCS V1(Portal Version 9.0.2.2.22) is working fine.
Please Advice me
Regards,
Durai.

Discussion Forum Portlet Question

Hi,
I downloaded and implemented jcriggs' version of the Discussion Forum Portlet and it works quite fine with one exception, the search. Does anyone know if the search function of that is supposed to be a full text search? It seems to only search on topic name and the first word in the message posted. Also does anyone know of a way to delete messages other than going into the database and deleting the actual record? I ran a bunch of test messages and want to remove them before I go live with it and give people access. I am assuming that going into the DB is the only way, but I am not sure.
Thanks,
Joe

Discussion Forum Portlet - Problems with JAVA and UTF8?

Hi
I installed the Discussion Forum Portlet successfully. It also seems that almost everything works fine. There's only a problem if I have new posts that include special German characters (Umlaute) like ä, ö, ü or special French characters like é, è or ç. They are saved correctly in the table but if you view the post the characters are not displayed correctly.
Example
input: ça va?
result: Ã§a va?
I know that there are problems with Java and UTF8 Database. Is there a possibility to change this (bug)?
Regards
Mark

Discussion Forum Portlet security

Hi
Googling "Oracle Discussion Forum Portlet" I found a number of security advisories, bascially saying that the discussion forum portlet has known security issues and that Oracle recommends using it for testing only and not in a production environment.
Anyone know if it is safe to use this portlet in a "closed" intranet portal, or is it better not to use it? Any other alternatives?
Thanks...

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

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

ERROR IN DISCUSSION FORUM PORTLET (9.0.4.0) (SEARCH)

I had downloaded and installed Discussion Forum (9.0.4.0) version.
It deployed successfully.
When I try the search feature in Discussion Forum Portlet, it display error message.
After input text in the search textbox and press the "Go" button, error message display "Error: JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null".
How can I solve it?

Discussion forum portlet is not NLS compliant, so its not capable of handling multibyte characters at present.

Discussion Forum Portlet Roles

Hi there. Is there any way of managing the roles of the Discussion Forum portlet that comes with GroupSpace and Weblogic Portal 9.2. I'm aware of how to assign different capabilities to different users,but i want to control what those capabilities should be.( I don't have the source of the pageflows that controls the portlets)
1. For example i don't want users to edit topics which they do not own, but they can reply to that topic.
2. Currently i have to assign a user the "Contributor" role if i want him to be able to reply to a topic, but this means he's also able to edit or add Forums and Categies.( Which is a capability i only want to assign to the "Owner" or "Creator" role.

If you can upgrade your application to WLP 10.0, the source for all of the collaboration portlets (Tasks, Email, Calendar, Adress Book, and Discussion Forum) is provided.
Note, however, that if you modify the source, it will no longer be supported by BEA. But, you should be able to accomplish what you desire.
