I am trying to use our Calumet XProc processor (http://developer.emc.com/xmltech) with oXygen 11 beta, but can't get the integration to work. This is what I tried: 1. I created an XProc Engine configuration ("Calumet") with the following command-line: [calumet-dir]/bin/calumet -i source=${cf} [calumet-dir]/bin/identity.xpl (This command line should just echo the source document to stdout.) The other options in the dialog I left unchanged. 2. I created a new transformation scenario and selected "Calumet" as the XProc processor. The other options in the dialog I left unchanged. However, when I apply the transformation, I always get the following error: SystemID: /home/vojtech/pipeline.xpl Engine name: Calumet Severity: error Description: Null or not stream result. Any ideas what may be going wrong? How exactly is the "XProc URL" setting used in the transformation scenario? I was also wondering if oXygen would be interested in providing a similar type of integration with Calumet as you have for Calabash? If so, I can definitely provide assistance with that.
