NOW UPDATED to work with Spotfire 7.5 and above!
NOW UPDATED to support Spotfire Binary Data files and to upload SBDF to the Spotfire Library!
This node creates a TIBCO Spotfire SBDF or STDF data file from the input table. SBDF is Spotfire Binary Data Format and is the preferred Spotfire native file format. STDF (Spotfire Text) is also included for support for legacy applications.
The node also complies with the latest KNIME file writer standards and so you can use knime://knime.workflow/file.sbdf (to write to a location relative to the root of the workflow folder) or knime://knime.mountpoint/file.sbdf (to write to a location relative to the root of the workspace folder).
To write to the Spotfire library, the URL must be in the format http(s)://spotfireserver:port/spotfire/libraryPath/file.sbdf - note that STDF cannot be saved in the Spotfire library.
IMPORTANT! You must use the Spotfire application server (TIBCO Spotfire Server), not the web server (Consumer/Business Author). Also, you MUST make sure the url contains /spotfire/ immediately after the server name.
Known Issues: When new file writer node is placed on the workspace canvas, the workflow credentials functionality does not work initially. If you connect an input to the node, the workflow credentials will then be available.
