WSRP Producer registration (unstable behaviour)

Hi,
I'm currently using JDev 10.1.3.3.0 build 4157 and building a webcenter application which makes use of both WSRP and PDK-Java portlets. I'm getting strange errors with WSRP Producer registration: in order to simplify things this description refers to the RichTextPortlet which is a prebuilt portlet but the problem is happening with every WSRP portlet producer, not with PDK-Java producers:
When I create the producer for the RichTextPortlet everything works perfectly, I run my app and personalize the portlet without problems. However, after several runs the portlets start to show the "Portlet unavailable" message and the server logs says something about the producer registration being wrong. When I test the producer connection in JDev it checks ok but if I try to refresh it, it fails. If I register an identical producer it works fine but the original producer doesn't.
The exception I get when I refresh the producer registration is:
oracle.portlet.client.container.PortletRemoteException: WSRP producer responded with an error (InvalidRegistrationException)

Yoel,
I think the WebCenter forum is probably the right place for this one.
Oh, wait, I see you already cross-posted over there. You sneaky little devil ;)

  • Transitioning WSRP producer registrations from development to production

    Hi there,
    we're currently struggling a bit with the notion of producer registrations vs. the need for separating our development environment from production.
    Here's what we do:
    1. We create a producer connection in JDeveloper, but using the development server's portlet deployment as WSDL endpoint
    2. We then continue to create some pages, instantiating portlets from the newly created producer as we go along
    3. We deploy that to our development environment. All is well!
    4. We (at some time in our projects lifecycle) try to go ahead and deploy to production. For that, we'd like to change the URL of the producer connection while preserving all the pages we composed (at design time), so far.
    5. First, we simply change the producer url in connections.xml before starting to predeploy. -> Error, since the ID of the registration handle included in our local MDS doesn't match anything that exists in the actual production environment.
    6. Next, we try to predeploy/deploy the EAR file as is, then change the actual producer URL using WLST (setWSRPProducer, registerWSRPProducer, degisterWSRPProducer, etc) or the Fusion Enterprise Manager. -> Doesn't work either, since deregistration/registration invalidates all the existing portlet instance files we have in our original MDS/MAR file.
    So here's my question: What are best practices you can recommend when working with WSRP producers and a (clean) separation between development, testing and production environment? Are design-time producer registrations/portlet instantiations even possible in such a context? Should we perhaps use the preference data migration tool for migrating consumer registrations from one environment to the other? Even when one of those environments is unstable (dev) and the other supposed to be stable (production)? Or should we (at the portlet-level) disable consumer registrations entirely? If yes: How to do this in WebCenter?
    Help is deeply appreciated :-)!
    Cheers,
    Chris

    Hi Chris,
    You raise good questions that I would love to explore further as well and it would be great if you could let me know what deployment approach you have come up with. Some of this is covered under section http://docs.oracle.com/cd/E17904_01/webcenter.1111/e12405/wcadm_imp_exp.htm and http://docs.oracle.com/cd/E17904_01/core.1111/e10105/deployer_role.htm which I am sure you have already reviewed. I have a much simpler problem with getting a Null Exception Error every time that I simply try to register a WSRP Producer with the sample .Net service - have you ever tried that and have come across the same issue?
    Thanks,
    Michael.

  • WSRP Producer Registration and Firewall Problem

    Hi,
    I am trying to register a WSRP producer in JDev 11g TP3, and am running into a problem with our firewall, which requires authentication. The WSRP producer is on a system inside our firewall, however it references a WSDL outside our firewall (http://www.oasis-open.org/committees/wsrp/specifications/version1/wsrp_v1_bindings.wsdl).
    I have my proxy configured via preferences->Web Browser and Proxy to use the proxy server, but exclude our domain.
    The problem I have is that I can either Check the choice to "Use Proxy for contacting the Portlet Product", in which case I get an http 407 error trying to access the internal server, or uncheck the choice, in which case I get a timeout accessing the WSDL outside our firewall.
    Does anybody know how to configure the proxy settings to allow me to access a producer inside our firewall, which references a WSDL outside our firewall?
    Thank you!

    Peter,
    Firstly, thanks for your answer. Which log files are you referring to? I didn't find anything wrong in the richtextportlet application log. The error appears when trying to refresh a previously registered producer.
    I'm using both PDK-Java and WSRP portlets and the problem only happens with WSRP portlets. The app is using ADF security with a lightweight xml provider, I'm running the app in the embedded OC4J and the portlets are being consumed from the built-in portlet ready instance (OC4J_Webcenter) in an Oracle Webcenter 10.1.3.2.0 AS installation.
    Thanks again,
    Yoel

  • Portal Standards Website - WSRP Producer WSDL unavailable

    Hi,
    I'm trying to use the portal standards website as a WSRP producer to prototype some WSRP work I am undertaking. From reading the "Registering a WSRP Producer or Web Provider on OracleAS Portal / Verification Server" document I believe that to register Oracle's Sample WSRP Producer as a provider in JDeveloper I need to use the URL
    http://portalstandards.oracle.com/wsrp/jaxrpc?WSDL
    however if I try to hit this using a standard browser I just get a 404 Not Found error. Trying it in the WSRP Producer registration wizard in JDeveloper just gives a connection exception "Failed to read WSDL from http://portalstandards.oracle.com/wsrp/jaxrpc?WSDL:WSDL not found:"
    Is this WSDL no longer available?

    I have found the following manual:
    "Oracle® Application Server Portal Developer's Guide 10g Release 2" - Configuring Your Application Server to Run JPS-Compliant Portlets (including Data Sources's Configuration).
    I have followed the necessary steps, but when I tried to test it (Registering and Viewing Your Portlet's Section (create a WSRP Provider)), I have the same errorr:
    Internal error WWC-00006
    Unexpected error ORA-00932
    WWC-35000
    I have verified via web browser my WSRP Producer WSDL Page, and it is correct.
    I have tested with different users (orcladmin, portal, etc), even I have included them in PORTAL_ADMINISTRATORS group. But it doesn't work...
    Another thing I have tested is to apply 4640471 patch, although I am not sure it should be necessary, because in ReadMe file, it is only for Solaris Systems, and I am working with Windows Server 2003 SP1...
    I am really desesperate with this error, do you have any idea to solve it?
    Thank you and regards.

  • WSRP Consumer - producer registration error : (100)continue return code

    I am trying to get an ALI WSRP Consumer working with the ALI WSRP Producer. Whenever I try to register the producer wsdl, the consumer fails with the error :
    Failed to get a service description from WSRP provider!
    Error message from WSRP provider: (100)Continue
    Any clues? I can successfully register this producer with a different portal's consumer. Is there a configuration property that needs to be set to allow the (100) response code? Or perhaps my Producer should avoid that response code in the first place? Has anybody run into this?
    Below is the stack trace generated by my consumer on the back-end (from ALI Logging Spy) :

    This seemed promising, but the proposed solution (adding 'servicePointManager expect100Continue="false"' to Web.config) had no effect.
    My consumer request actually does not include the "Expect: 100-continue" header and receives the 100 response anyways. My understanding now is that this is okay (thought I'm not sure why) and that the client should be expected to handle that response code in any case.
    I am wondering if there is an issue with the combination of products in my environment that is not supported by this product?? I am using
    IIS 5.1,
    .Net 2.0
    AquaLogic WSRP Producer 1.1/WebCenter WSRP Producer 10.3.0 (tried both)
    I am testing this producer in two environments -
    - AquaLogic Consumer running on AL Portal 6.5. When the WSRPConsumer is configured with the producer wsdl, it fails with message "Failed to get service description from WSRP Provider: .... faultString: (100) Continue".
    - Liferay - AFTER successful registration, attempts to deploy my registered .Net portlet (simple hello-world) result in an internal exception thrown in the Producer [Bea.Portlet.Management.PortletManager.LoadPortlet(PortletManager.cs:line 114)] Error loading PortletContainer: Bad PortletState. No request is made to my .Net application.
    It appears from both of these tests that both my producer and consumer are having fundamental problems that do not seem overly exotic (although I have successfully registered other WSRP portlets with the AL Consumer). However, I have not come across much information on these sorts of problems.

  • WSRP / Automatic producer registration

    Hi,
    i'm looking for a way to register my wsrp producers with a jython script.
    Is it possible and how ?
    Thx a lot
    Emmanuel

    Hello Emmanuel,
    It should be possible to set up something on the server which your script can call to register a WSRP producer.
    On the server side, you can use the ProducerManager API to register new WSRP producers. See:
    http://download.oracle.com/docs/cd/E13155_01/wlp/docs103/javadoc/com/bea/wsrp/consumer/management/producer/ProducerManager.html
    You can get an instance of the ProducerManager class by calling:
    ProducerManager.Factory.getAdapter() Kevin

    We use WSRP 2.0.
    We suppose that problem appeared after unsuccessfull attempts to deploy portlet which use Oracle ADF libraries.
    While trying to deploy that portlet we've got java.lang.outOfMemoryError, and logs of WSRP instance contained no errors.
    Any help would be appreciated.

  • Federated Portal Network Blues - can not connect to WSRP producer

    Hi,
    I'd like to embed some JSR-168 portlets into my SAP EP but fail immediately when trying to add the WSRP content producer.
    I have a setup of two portals, one is SAP EP 2004s (SP13) and the other a JBoss Portal v2.6.4. I'd like to share my JBoss portlets to SAP and vice-versa for evaluating the interoperability of SAP systems with the real world.
    But alas, I'm struggling on the basic setup of my SAP EP...
    Here is my problem:
    When I configure a WSRP-producer it all seems to work right but I can not connect to it, e.g. I can not register and test the connection. The connection test fails because of :
    Producer object was found
    Could not retrieve the WSDL file; the handshake URL may not exist or may be invalid
    The SAP systems runs behind no proxy at all, so this can't be the issue. When testing the same WSRP producer URL from JBoss portal it all works fine. The URL I used was a WSRP test site from Oracle, see [http://portalstandards.oracle.com/portletapp/portlets?WSDL].
    Does anyone have a glue what might be missing on my SAP Portal? The standard log gives me no clues at all I've been tail minus effing the thing for hours...
    The SAP documentation - SAP Library, various E-Learning things - couldn't solve the problem for me...
    Thanks for your support!
    regards,
    Christian

    Hi,
    Unfortunately I do not have any experience with connecting to JBoss, but perhaps this document can help you analyzing your issue:
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/703cfbbd-e85e-2a10-00a3-ecd502c08e82
    Good luck!
    Best regards,

  • Error in getting Username from UserPrincipal in WSRP Producer

    Hi,
    In WSRP Producer,we are trying to get the the username from the UserPrincipal which was sent by the consumer.
    String userID = this.getRequest().getUserPrincipal().getName();
    I'm getting an Null pointer exception in one of the Producer but the same kind of code is working in other producer.
    The two producers are in different domains. And the Consumer is same for the both Producers.
    Could anybody help me to find out what went wrong. ?
    Thanks,
    Mohan

    Hello,
    It is likely that your two producers are configured differently for security (SAML). For the producer that isn't working, it is likely that you just need the proper entries in your key store to get it to work. Look at the key store for the producer that is working, and try to ensure the other producer is similarly configured.

  • Configuring Custom JavaScript/CSS and YUI in WSRP Producer Portlet

    I am trying to find information on how to setup/configure WebCenter for WSRP Producer Portlets that have YUI and custom javascript/CSS. While we have gotten some of the YUI features and custom javascript/CSS to work, we find that some references are not loading such as custom CSS and images. This appears to be a result of the URL rewrite not occuring for some of these references. It appears that WebLogic Portal supports this capability and can be configured using a dependency file for such needs but I have been unable to find a equivalent for WebCenter.
    Any help would be greatly appreciated.
    Best Regards.
    Carl

    When you are providing javascript or css path,provide the absolute path.
    like src="http://<server>:<port>/portlet context root/images/some.png".
    In that way custom javascript/css will work.
    Regards,
    Hoque

  • Error when extending portal domain to be a wsrp producer

    I have created a Weblogic Portal domain, and then created a Portal web application deployed in Weblogic Portal domain.

    When I try to extend the domain I get the following error:

    By default, portal domains include support wsrp producer - so there is

  • Integrate OAS Portal with E1 - WSRP Producer

    Hello,
    I want to integrate OAS Portal with E1. I am following: "JD Edwards EnterpriseOne Tools Release 8.98 Portal Reference Guide for All Portals and Platforms" and I have a doubt about how to register a new WSRP producer for Oracle Portal Server.
    I am working with:
    - OAS Portal 10.1.4 (integrated with Windows Server 2003 SP1)
    - JDE E1 8.12 Tools 8.98
    - Each one are in a different physical machine.
    I am not sure what is exactlly WSRP producer. In the manual, it says that it is: JDE E1 HTML Web Server.
    When I amb in the second step to register the new WSRP (Provider Description (WSDL)) I have the following error:
    "Internal Error *(WWC-00006)*
    Unexpected error: *ORA-00932*: Inconsistent datatype waited an IN argument at position 2 that is an instance of an Oracle
    type convertible to an instance of a user defined Java class has obtained an Oracle type that could not be converted to a java class *(WWC-35000)*"
    In WSDL URL I have specified:
    http://HOST_E1:8083/jde/wsdl/WSRPService.wsdl
    And if it is acceded via web browser, the result is:
    - <definitions targetNamespace="urn:oasis:names:tc:wsrp:v1:wsdl" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:bind="urn:oasis:names:tc:wsrp:v1:bind" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
    <import namespace="urn:oasis:names:tc:wsrp:v1:bind" location="local.wsdl" />
    - <service name="WSRPService">
    - <port name="WSRPBaseService" binding="bind:WSRP_v1_Markup_Binding_SOAP">
    <soap:address location="http:///HOST_E1:8083/jde/WSRPBaseService" />
    </port>
    - <port name="WSRPServiceDescriptionService" binding="bind:WSRP_v1_ServiceDescription_Binding_SOAP">
    <soap:address location="http:///HOST_E1:8083/jde/WSRPServiceDescriptionService" />
    </port>
    </service>
    </definitions>
    1) Is correct this result?
    2) In which file can I find the port number that I need to register the WSRP?
    I am not sure about this port, but it is the number port to enter to JDE's Web (http://HOST_E1:8083/jde/E1Menu.maf)
    3) Is necessary to do any step before?
    Thank you and regards

    I have found the following manual:
    "Oracle® Application Server Portal Developer's Guide 10g Release 2" - Configuring Your Application Server to Run JPS-Compliant Portlets (including Data Sources's Configuration).
    I have followed the necessary steps, but when I tried to test it (Registering and Viewing Your Portlet's Section (create a WSRP Provider)), I have the same errorr:
    Internal error WWC-00006
    Unexpected error ORA-00932
    WWC-35000
    I have verified via web browser my WSRP Producer WSDL Page, and it is correct.
    I have tested with different users (orcladmin, portal, etc), even I have included them in PORTAL_ADMINISTRATORS group. But it doesn't work...
    Another thing I have tested is to apply 4640471 patch, although I am not sure it should be necessary, because in ReadMe file, it is only for Solaris Systems, and I am working with Windows Server 2003 SP1...
    I am really desesperate with this error, do you have any idea to solve it?
    Thank you and regards.

  • Where is the Oracle WSRP producer?

    Hi, I am looking for the Oracle WSRP producer located at http://portalstandards.oracle.com/wsrp/jaxrpc?WSDL before. But the URL does not exist now.
    Could anybody let me know the producer? In fact I saw those remote portlets on http://portalstandards.oracle.com/portal/page/portal/OracleHostedWSRPPortal/Samples. Thanks.
    Xiaobo Yang

    Thanks Sandeep. But it seems that I have set up such a producer by myself with what you mentioned. What I want is an existing Oracle WSRP producer which I can use for testing.
