Both
the applet and servlet can be set to retrieve the configuration
properties from a data file. The configuration file is
simply a list of the property names with the value for
each property.
The
first 20 character positions of a line in this file specify
the property name whilst position 21 onwards represent
the value for that property.
Any
line in the file which is either blank or begins with
<!-- will be ignored. Therefore comment lines may be
added to file by beginning the line with <!--.
We
recommend that, rather than building a configuration from
scratch, that you take a copy of the example file pieprops.txt
file and modify the values to suite your implementation.
In
both the applet and servlet the configuration file is
specified via a URL parameter and therefore the file can
be placed in any directory accessible via URL. However
we recommend keeping this config file in the same directory
as your web page which incorporates the pie chart.
For
a full explanation of each property and range of valid
values please see the
Configuration Options and Parameters
section.
