Destinations to SCC cannot be configured

Hi,

I have a problem when configuring destinations on my SAP Netweaver Cloud Account. I can enter it but when I re-open the server configuration, it shows no destinations. The application fails because it cannot access the destination folder (which is apprently not present). The root exception is

java.io.FileNotFoundException: ./config_master/service.destinations/destinations/login (No such file or directory)

and this causes then the

javax.naming.NamingException: Error while attempting to resolve reference

with various ConfigurationException and HttpDestinationException in between.

Saving and uploading the destinations seems to be normal, from the Eclipse point of view. The upload window closes and the error log only contains a note about a changed configuration. I use neo-sdk-1.5.2, sapcc10SP00P_3-10011098, and Eclipse Juno incl. the Neo Tools.

I would be happy for any hint how to store destinations persistently.

EDIT: this only happens to destinations of type "OnPremise". Internet destinations are stored and retrieved successfully. The destination is HTTP with NoAuthentication.

Best,

Kay
