Retrieving Configuration Data from File

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 lineprops.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 line graph.

For a full explanation of each property and range of valid values please see the
Configuration Options and Parameters section.
