Register web provider

Hi,
I'm working 5 weeks with Portal. I've never had troubles with registering web providers.
Suddenly I can't register new web providers and modify already registered providers...
I've been working a lot with JSP portlets that contain BC4J. Sometimes these portlets did not appear on the screen. When I refreshed several times the browser... they appeared !
Now also my server reports problems : when I start the Apache server, he says there's an error !
Has somebody an idea of what the problem could be ?
Thanks,
Bart

Matt,
Acutally, I have never seen this error before. I had to check around to see if others had seen this. Are you doing anything different than your other web providers? Especially with the User Interface.

Error while registering web provider

Hello
I have a web provider developed in JPDK. I have deployed it successfully to an Standalone OC4J and I can access a page that says something like that:
Oracle9iAS Portlet Application Test Page
This page lists the portlet providers available in this web application. Use the registration URL in combination with the provider's service name to register the provider. Click on the service name link to view the provider's test page.
Registration URL http://myserver:8888/intranet/providers/
Service Name
provideredd
providergenerales
provider_edd_desarrollo
But when I try to register the provider in portal with the registration URL I got the error:
An error occurred when attempting to call the providers register function. (WWC-43134)
The following error occurred during the call to Web provider: 500: Internal Server Error (WWC-43147)
I'm sure my OC4J is up and running because I can acces the url http://myserver:8888/intranet.
Please help me.

I have a similar problem where I have portal installed on a machine called portal.mgmt, which is on a network that users cannot access. Connection to portal.mgmt can only be made from our local network via a machine called install.mgmt. In a sense I guess it is acting like a reverse proxy or firewall.
I have run ssodatan on portal providing the install.mgmt URL and can access most of Portal pages navigating to http://install.mgmt/ except any of the servlets. Actually the only servlet I can access is the sample IsItWorking servlet.
In my java jserv.log file I am getting the following error:
java.net.SocketException: Connection reset by peer
at java.net.PlainSocketImpl.socketAvailable(Native Method)
I can only assume, from reading the Troubleshooting guide as mentioned above, that portal.mgmt is trying to make a separate connection to the install.mgmt box and is failing.
The network between portal.mgmt and install.mgmt is very restricted as to what can be run and what protocols and ports can be used. Is this restriction causing the problem?
I see that Jserv uses port 8007, is this port used to communicate between machines?
Are there any ports that need to be opened?
I have tried using another machine called ogg as the firewall/access server and get the following error as well.
java.net.UnknownHostException: ogg
at java.lang.Throwable.fillInStackTrace(Native Method)
Any help on this one would be very much appreciated, as I am very stuck at the minute.

seems to me the oracle.aurora error would be coming from the database. No errors appear in the Provider's log files.
Any insight would be appreciated.
Thanks!

Can't register web provider

I can add database providers but not web providers. When I hit the apply or OK
button after filling out the form for a web provider I get the following message :
"An error occurred when attempting to call the providers register function(WWC-43134)
An unexpected error occurred: ORA-29540:class
oracle/webdb/provider/web/HttpProviderDispatcher does not exist(WWC-43000)"

Jon, I'm surprised that database provider registration works. We'll have a look at that. As for the web provider, can you give me the URL that you were trying to register? We recognize that the error messages need to be much better. Typically, what causes things to go wrong is that the URL is not published to the "Internet".

How can I solve this problem?
Thanks forward
Ivan Samuel Tejera Santana

Ready!
I changed oc4j server version from 9.0.4 to 9.0.2.1
and it works.
Four days to realize of this fact!
I hope than this can help to the rest of oracle community.

Error in registering a provider for External Application for Web Clipping

Getting Error: The provider URL specified may be wrong or the provider is not running. (WWC-43176)
when trying to register a provider for an external application for Web Clipping

Hi Vineet,
The admins applied a patch to my version of the OracleAS 10g Version 9.0.4. and now I able to register a provider with the same URL but different Provider Name. I added My Yahoo Web Clipping from the Portlet Staging Area. That works fine but when I click on the check mail link in the Web Clipping Studio it gives me the following error. I have tried several times and I get the same error....
An exception has occured : WCS-514 -- Get status code 403 to URL http://us.rd.yahoo.com/my/prop/mail/*http://mail.yahoo.com/ by method get
Please click "Cancel" or "Back" in the above panel (if present) to retry. Otherwise, please try to click "Back" (from the browser) to go back to the Oracle Portal page to restart.

Cannot register the Web Provider Sample in Portal

Hi,
I downloaded the PDK-Java Framework and Samples to install in portal. The Portal version 3.0.9.8 on NT 4.0 platform.
I followed the instructions all the way to testing the Web Provider Sample set up. I can execute the sample from the Oracle HTTP Server. The test page is displayed correctly. Then I try to register the web provider in Portal. And I encountered the following error:
An unexpected error occurred: ORA-29531: no method getPortletList in class
oracle/webdb/provider/web/HttpProviderDispatcher ORA-06510: PL/SQL: unhandled user-defined exception

An unexpected error occurred:

Can anyone tell me what I need to do?
Thanks;
Kelly.

Kelly,
You want to take a look at the following to try to debug your situation.
1. Make sure that no tags in the provider.xml say <getPortletList> this tag should not be in there are would not be in there unless altered.
2. You may have some invalid Java classes in your portal. You may want to check the status on your packages.

Registering a provider built in java class.

Hi all,
I have done an application in oracle portal which has pages made in portlets. I have used pl/sql and htp packages in this application. I have created a search module in jsp along with java classes. After that I deployed this as a war file in oracle app server 10g. deployment done successfully but when I am registering a provider in oracle portal, it cannot find the java classes. can anyone please tell me how to register a java provider in oracle portal.

You need provider.xml file for that.
WEB-INF\providers\providename\provider.xml
I think you have to make Portlet from your jsp file.
I have only made Struts-Portlets (http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/pdkstruts/portletize-your-app.html)

Bpel web provider and portal

I am trying to get the worklist app portlets to deploy on the oracle portal. the documentation indicates that the web provider which needs to be registered in the portal can be found at the url http://bpel_host:bpel:port/BPELPortlets/providers. That url returns a page not found message. Does anybody know if this is the right url or do I need to use a different url. Else do I need to deploy some other component to make the web provide active. thanks for the help.

Are you running HTTPS with your portal or HTTP? I cannot get the BPEL portlets to work with HTTPS.

Migration of web provider customization data

I am now using portal 9.0.2.3 in windows 2000 server
It is my understanding that exp/imp of web providers and its customization data is not supported in portal.
I have logged a TAR in metalink and the analyst said the I have to migrate the preference store from development to testing environment and I am using db preferencestore in my development environment.
The question is when I register the provider in production environment, a new provider id and path are given, what is the procedure to resume the customization data after I imported the preference store.
John Lui

The import/export of web provider customization data is not currently available.

But, when I press the preview button next to it, It shows "Error: The listener returned the following Message: 500 Internal Server Error".
Please give me a clue where I am going wrong.
Thanks in advance.

Well, over the past few days while desparately trying to make my portlets work, I have tried several things. I started initially with a downloaded version of pdk that contains samples of v1. My first message above reflects the setup I used with v1. While trying to figure-out the problem for error 500, I tried v2 but the same problem persisted.
However, the clue by Mr. Peter Moskovits to check the application.log has helped me to finally resolve the problem.

How to Register the Provider

Based on the Docuementation for Registering the Provider :-
1) Under the Administrator Tab, click on Add a portlet provider within the portlet called provider.
Where can I find the administrator tab?

I have login onto OTN with my OTN Account and also the portalstudio.com with the same account and password. I am able to go in successfully but when I attempt to register a web provider, it failed. I cannot see the administrator tab as documented. Is it true that my OTN Account does not have the ability the register a web provider ?

Unable to address internet web provider from inranet portal

Folks,
I'm trying to register an internet web provider from an intranet portal (3.0.9.8.2) but without success. I can call the provider's testpage from my browser but when activating the proxy on provider registration I'll get an error (WWC-43134; java.io.InterruptedIOException: Connection establishment timed out (WWC-43000)
). Do I have to set a proxy option anywhere else than under global settings? The provider servlet is the standard JPDK 3.0.x provider. Is the connection between portal inside and provider outside bi-directional?

Hi Detlef,
You probably don't have permission to access the host on which proxy server resides. Since all calls to remote portlet providers are initiated from Oracle8i JVM which is inside your database, you need to issue
the following command (under SYS): call dbms_java.grant_permission('SYS', 'SYS:java.net.SocketPermission', '*', 'connect,resolve');
This statement lets you access any host from Java classes running in your Oracle8i JVM. Probably you
also need to setup proxy settings for the JVM. Also take a look at trace file in udump directory for your database. It should be full of useful information! ;-)
Hope this helps
Serguei
