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.
-
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.
-
Set the GREOUTPUTDIR environment variable to the specified Web root
directory in the environment of the GRE daemon (greportwriter -l).
