This note provides suggestions for the error DCA-40012 in WebCenter Portal

The error occurs when trying to display a custom taskflow in a WebCenter Portal page that consume a web service data control.

Steps To Reproduce:

  1. In JDeveloper, create a new application with a web service data control to any SOAP web service. Then create a simple fragment task flow that displays the results a call to one of the methods.
  2. Deploy this task flow to WebCenter Space (create a wrapper WAR file and deploy as a shared library to WC_Spaces, then reference the library in DesignWebCenterSpaces application).
  3. In Spaces runtime, add the new task flow to a resource catalog, then add the task flow to a page in a space. At this point the page will either freeze or an error will occur.
  4. Looking in the logs for WC_Spaces.out, it seems that there is some problem with the way the connection details have been deployed as the following is shown:
    "<Warning> <oracle.adf.adapterDC.webservice> <BEA-000000> <Verify if the connections.xml has valid metadata defined for connection 'spaces'>"

Shortly afterward, the following is then shown:


Testing the task flow locally in the integrated WebLogic works as expected.
