When you run a Web DataWindow application, the definitions of your DataWindow objects must be available on the component server. You can ensure this by copying the PBL or PBD file that contains the definition of the objects to the server. If you are using EAServer, the files must be in the server’s path, or if the server component is running as a service, in the system path. COM+ always runs as a service, so the files must be in the COM+ server’s system path.
