Preview reports in distributed mode

If you are running the GRE daemon on a different machine than the DVMrunning report application, and the output type is either "PDF", "RTF", "XLS", "XLX" or "HTML" (as specified by the fgl_report_selectDevice function), you must set up the environment before you can preview reports.

Important: The following instructions are not necessary if the GRE and the DVM are running on the same physical machine.
  1. Start the Web server service by invoking the command grehttpd.

    Located at GREDIR/bin/grehttpd, the following options are available:

    • -p port, where port is the port number. The default port is 8080.
    • -q activates the Web server service in quiet mode.
    • -d directory, where directory specifies the Web root. There may be several. If nothing is specified, then the current working directory (".") is taken as the Web root.
    • -license prints the NanoHTTPD license.
    Note: The Genero Report Engine ships with this minimal Web server. However, any other web server capable of serving static files can be used.
  2. Set the GREOUTPUTDIR environment variable to the specified Web root directory in the environment of the GRE daemon (greportwriter -l).
