Registering Discoverer Portlet Provider with JDeveloper WebCenter

Is it possible to register DPP with JDeveloper? What kind of portlet producer is DPP, WSRP or Oracle PDK? Can anyone tell me the specific steps (i.e., what to fill in for the URL, subscriber ID, etc.)?
Thanks,
-warren

You might want to ask this on the Discoverer forum.
It depends on the type of portlet DPP is - JDeveloper can register both WSRP and PDK portlets.

Discoverer Portlet provider Register with Oracle AS Portal

Hi All,
I am trying to register the Discoverer portlet provider with Oracle AS Portal. I could able to launch the portal homepage successfully by giving the following url
http://<host.domain>:<port>/pls/portal
But, when I clicking the "login" to login it is giving me an error...
I also ensured that OssoIPCheck parameter to be off in mod_osso.conf file.
Please let me any configuration I need to do as part of this registeration. Thanks in advance.
Best Regards
Venkat

Hi Michael,
Thanks a lot for the prompt response. Actually we are going to provide an Oracle BI solution using OWB, Discoverer, Oracle 10g to one of our clients. And we personally feel that using Oracle 10g AS will prevent many unexpected problems in the application.
But the decision of choosing the portal tool is pending at the clients side and we need to help them out with the better options.
they are also looking for IBM websphere, and IBM has said that they have a portlet factory builder that helps portal to integrate with any other portlets.
Is it so that the ability to integrate any kind of portlet lies with the portal independent of the kind of portlet?
In our case... does it mean that IBM portal can integrate the discoverer portlet even if Discoverer does'nt provide for integration with non-Oracle portal?

Discoverer Portlet fails with ora-01017

This is about OAS 10gR2
Middle tier version: 10.1.2.0.2
Discoverer version: 10.1.2.48.18
I've manually changed password for Discoverer EUL Owner schema (using "alter user blablabla identified by blablabla" statement, in sqlplus) and now I can't register discoverer portlet provider.
It fails with the following message:
"Error!
BaseException is ... ORA-01017: invalid username/password; logon denied
Recognizing component versions...
ptlshare.jar version: 10.1.2.0.2
pdkjava.jar version: 10.1.2.0.0"
I make no idea what was the password for discover5 schema before and that was the reason i changed it.
Already have redeployed discoverer.ear file in OAS administration, but it didn't change a thing.
I've tried the Discoverer Forum but no one there answered my question.
Any ideas of what could bring this kind of issue?
TIA
Marcos

Solved!
The problem was that when I changed user password in database, i did not synchronized Database user with OID attributes.
Step by step solution:
Reset Password for DB user in sqlplus with
"Alter user XXXX identified by YYYYYY;"
Enter OID (Oracle Directory Management) as the "superuser" (ORCLADMIN);
Navigate to
-> Entry Management
-> cn=OracleContext
-> cn=Product
-> cn=IAS
-> cn=IAS InfraStructure Databases
-> cn=orclReferenceName=appsdb.ecovias.com.br
-> OrclResourceName=DISCOVERER5
Alter orclPasswordattribute for the user, using the same password you have resetted in Sqlplus.
Bounce OAS middle tier instance (ompnctl startall/stopall or using Application Server Control).
Touché, it's done!
Alternativelly, you can keep geniuses away from altering passwords...
Thanx y'all...

I had a similar problem, first I made sure my discover connections worked by connecting to discover through IAS. Then when I registered the discoverer in portal, it timed out the first couple of times. I then refreshed the browser window a couple of times and it worked.

Discoverer Portlet Provider Error

Good day. I would like to seek anyone's assitance with the errors encountered below when trying to manipulate Discoverer Portlet Provider through Oracle Portal:
1. While trying to view Discoverer Portlet Workbook or Worksheet:
"The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
2. While trying to delete Discoverer Portlet Provider:
"The page cannot be displayed" error from Internet Explorer.
3. While trying to deregister Discoverer Portlet Provider:
"The provider could not be contacted, do you still want to delete provider "DISCO_DATAMART_PROVIDER"?
The provider could not be contacted and its deregistration function was not initiated. Deleting the provider will remove it from the portal. Additional action may be necessary by the provider to remedy the failure to call its deregistration function."
Here's our infrastructure versions:
Portal version 9.0.2.2.22
Discoverer Version Release 2 (9.0.2.53)
Previously, the highest release of patchset was installed in our machine but I've reverted it back to a lower patchset on both cases, same error was encountered for the above-mentioned.
We've successfully registered discoverer portletprovider and created a public connection via "General Discoverer" in OEM. And Discoverer Viewer / Plus are working properly.
I think this problem has been posted in metalink and some other sites but no definite answer yet (as far as I've read).
Any help would be greatly appreciated.
Thanks in Advance.

It seems wherever section I post this I can't get any solution. I was instructed by someone in this forum to post this in the discoverer section. Up to now, no replies yet. I already raised a TAR for this and still no answer. I've researched through metalink and so many of us have this problem. Attention Oracle, we really need your assistance for this product of yours. Please help us out.

Virtual Host change doesnt update discoverer portlet provider image locatio

We have recently created a virtual host for our oracle portal. Original was CUKPORTAL.cseu.root.local and the new virtual hosts created were bi.portal.uk (bi tier) my.portal.uk and sso.portal.uk (for IMT).
All pages, images , portlets were updated to reflect the new URL's except for the discoverer portlet provider. Actually , it works fine except for the lcoation of the portlets reference to the original icons for the list of worksheets portlet. When we see the page source behind the html page where the portlet is on , I can see that the images (like the expand workbook image) , still reference the old URL ie CUKPORTAL.cseu.root.local:7780.....etc
We have re-registered the provider with the new URL , ie bi.portal.uk:7779 etc but although the portlets can be called and placed in pages , the images do not appear as a result of the location to the images.
Any help would be greatly appreciated as this is the last problem before we go live.

Hi,
Its good that u pasted the complete log file. In your environment you have to run this upgrade tool only once from any of the middle tier.
And with respect to your error that u got in precheck is quite simple. All u have to do is just run this script from by connecting to portal schema using sqlplus.
Run dropupg.sql
Location-------- /raid/product/OraHome_1/upgrade/temp/portal/prechktmp/dropupg.sql
Later you re-run the upgrade tool and let me know the status.
Good luck

Error when registering a portlet provider

I got the following error when registering a new portlet provider:
An error occurred when attempting to call the providers register function. (WWC-43134)
The following error occurred during the call to Web provider: 301: Moved Permanently (WWC-43147)
May I know what I may have done wrong?
I was able to open the portlet provider page by itself
Thanks

Can you double check whether the provider node is accessible from the portal middle tier (ping)?

Discoverer Portlet Provider, No Response from Application Web Server

I must have some odd configurable incorrect. I hope one of you can help me out and point me in the right direction.
My issue involves the "Discoverer List of Worksheets" portlet. It will display all the workbooks and I can drill in and see the worksheets, but, when I click/choose a worksheet, it will return within a couple seconds and display "No Response from Application Web Server" in bold red letters, then "There was no response from application ...", then "Please notify the site's webmaster ...". I have spent the day trying to lock down a log on the http server, j2ee, web cache and used enterprise manager to see logs which changed immediately after the error but didn't seem to find much.
What am I missing? Is there a timeout somewhere? Does it look like I missed something when I configured anything?
Below are the configurables and answers to some of the obvious questions.

RE: Public Discoverer Portlets

Hi,
I have a strange problem. I created a discoverer workbook and shared it with Public. Using the public connection I created, I placed two of the worksheets on my portal home page which is accessible to the public. Everything worked fine and has been ok for several months. Last week, I added additional worksheets to the workbook and tried to access them via discoverer portlets using the public connection. When I authenticate against the portal, I can see the discoverer portlets on the page. However. when I go to the page without authenticating, I can see everything on the page except the discoverer portlets. I have tripled checked the portlet default settings and the option to "display data using publishers connection" is set. All of the worksheets in the workbook access the same table. Why is it I can see some of the worksheets and not all using the same connection?
Does anyone have any suggestions? I am desperate!
I am using OracleBI Discoverer 10g (10.1.2.1) and Portal ( 10.1.4)
Thanks

You have a good reference in the chapter 11 of the Oracle9iAS Discoverer Configuration Guide.
You have to register the portlet provider. When it ask you about the URL you have to type http://<hostname[:port]>/discoverer/portletprovider.
Then you can add the two porlets in any portal page.

Could anybody tell me what I should do.
Yours,

Hey Thomas,
You are registering your Web Provider with Oracle Portal. When Portal attempts to register your provider, it attempts to contact the listener that serves your web portlets. If you have already accessed the sample page: http://host.domain:port/servlet/sample according to the installation instructions, the Portal may not recognize your machine. Make sure the machine where Portal resides can access your Web Provider listener. If you Web Provider server is not part of the DNS, then add an entry in the Portal Server's host file.
Tyr this and good luck

Cannot find discoverer portlet in portlet repository (9iAS rel2)

I would like to use discoverer portlet in my portal page. I have already install 9iAS 9.0.2.0.1 + 9iAS discoverer patch (9.0.2.5.3) and also patch 9iDS Discoverer to the same version (all products on Windows 2000). Then register the discoverer provider, it was successfully. But when I tried to add discoverer portlet from my portal page, I cannot find discoverer portlet provider in the repository. This happen without any errors. Any suggestion ?

Try to refresh your Discoverer Portlet Provider. It should do the trick.

Line numbers on Discoverer Portlet

When I create a Discoverer Portlet in the Portal, the worksheet is displayed with a line number that I cannot control. In Discoverer Plus, you have the option to supress line numbers while building a worksheet, but when you deploy a worksheet to the Portal (via the Discoverer Portlet provider), you get the line numbers no matter what.
The problem is that the line numbers that are automatically added are in a 11 or 12 point font so it makes each row much taller than I need it to be.
Is there any way to supress these line numbers?
Thanks,
TGF

This is a known issue in Discoverer portlets and we are working on a resolution.
