Register WSRP Provider failed

Question

Hi,
I'm trying to register a WSRP provider (using WSRP Preview Portal) but it is failing.
The Provider is deployed on a OC4J standalone version (running on the development machine).
The URL is accessible through a webbrowser:
http://10.1.40.87:8888/javaPortlets/portlets?WSDL
here is the error message I get when finishing the registration process:
An error occurred when attempting to call the providers register function. (WWC-43134)
An error occured during the call to the WSRP Provider: Java stack trace from root exception:
java.rmi.ServerException: Internal Server Error (caught exception while handling request: oracle.webdb.wsrp.server.ContainerRuntimeException: An internal error has occurred in method <init>)

at oracle.webdb.wsrp.client.design.v1.OraWSRP_v1_Registration_PortType.register(Unknown Source)
. (WWC-43273)
Register WSRP providers running directly on the Portal-Machine is working.
(http://hv-lr-nwa1.mdkbw.de/jsr168Portlets/portlets?WSDL)
Is this a problem with the proxy settings? If yes: I can't see the 'Proxy Settings' part in the 'Services' Portlet (as I can see it in the 'normal', not the preview, portal) to change the settings.
What else could cause this problem?
Regards,

Hi,
I've got a similar problem again. I was able to register and refresh WSRP providers for a while, but now I get an error message again.
An error occured while trying to refresh the Provider. (WWC-43190)
An error occured during the call to the WSRP Provider: java.rmi.RemoteException: HTTP transport error: javax.xml.soap.SOAPException: Unable to internalize message; nested exception is:

When I load a portal page with a portlet (from an earlier registered WSRP provider) I get now an error in the application log:

I can't remember that I did changes to the OC4J-Config.
What could be the reason for that?
