Last updated on JANUARY 22, 2021

Applies to:

Oracle WebCenter Portal - Version to [Release 11g]
Information in this document applies to any platform.


When attempting to run a WebCenter Portal Application with a WSRP Portlet, the following error occurs:

Portlet unavailable

The WebCenter Log shows the old URL:

<Jan 3, 2011 10:59:15 AM EST> <Error> <oracle.portlet.client.connection.wsrp.HTTPClientTransport> <WCS-40151> <A request to the producer URL "http://<HOSTNAME>:<PORT>/<PRODUCER_NAME>/portlets/WSRP_v2_PortletManagement_Service" resulted in a status 500 response with fault string "java.lang.ClassCastException: org.apache.xml.dtm.ref.DTMManagerDefault". The fault code given was "env:Server".>

This happens after deleting and reinstalling the WSRP Portlet Producer.


The issue can be reproduced with the following steps:

  1. Deploy a WSRP Producer in WebLogic.
  2. Deploy a WebCenter Portal Application that calls a Portlet from the producer.
  3. Run the application and confirm it runs fine.
  4. Delete the WSRP Producer and deploy it again from a different server/machine so the Producer URL will be different.
  5. Run the WebCenter application.
    This should return the error.
