The applet is setup here to read both the configuration data and the graph
data from a server side processes, in this case a Java Servlets running on our web server.
The SHbarDataServlet ( click
here to view code ) is a simple servlet designed to demonstrate how a servlet can be used to return data to either the graphing
applet or servlet. As you will see the main routine ( doGet() ) uses the method GraphData() to construct the return data. Although
in this example the GraphData() routine simply builds the return data from 'hard coded' values, in practice this routine would
be expanded to first gather data from any number of data sources. eg. databases, files other server processes.
The SHbarConfigServlet ( click
here to view code ) again is just a simple servlet to demonstrate the method. The routine ConfigData() is used to construct
the return data from 'hard coded' values. Again, in practice this method would be expanded to derive data from a number of data
sources
For a full explanation of and range of values for the above parameters please
