Hi, i have no idea what you want to achieve, so i make some guesses. HINT: it is always usefull to say what you want to accomplish and why! I read the documentation this way: in SAS 9.3 if you have a STP V2 you can execute your STP on a SAS STP Server or a SAS Workspace Server (e.g. in SAS Enterprise Guide). This feature is new in SAS 9.3. I guess when you want to execute your STP on a SAS Workspace Server you need to use the API for the Workspace Server? see: SAS(R) 9.3 Integration Technologies: Java Client Developer's Guide Then there is the question why you need the streaming results? Usually a STP writes all content to the fileref _webout which is streamed back to the client. If you can manage to execute the STP on a Workspace Server you can simply download the content from this fileref in binary mode to your client and have the same result. Kind Regards, Andreas ...
