Reproducing the Issue

  2. Click "New Document"
  3. Choose "Connect to SAP Business Warehouse"
  4. The dialog box freezes for a few seconds and then the error message pops up. The server dropdown box is empty


This issue is caused by a self referencing environment variable in Windows. For example:

CLASSPATH=%CLASSPATH%;C:\Program Files\Java\jre7\lib;


Remove or correct the self-reference environment variable definition from Windows Control Panel -> System -> Advanced System Settings -> Environment Variables.
