> to view barcode fonts DESTYPE parameters is must be "FILE" and this send the pdf file to cache directory.
Not sure what's your problem here... in all our reports calls we use DESTYPE=CACHE, and we have no problems at all with barcodes reports (once done the correct configurations).
PaulM , the problem is.. if I define DESTYPE=FILE the report server generate the pdf file whith barcode correctly in cache directory but,
If i define DESTYPE=CACHE the report is open in navigator and view symbols instead of barcode font.
Follow this instructions to configurate the reporte server.
