Applet Example 5 - Data from Server Side Processes

if you do not see the graph below then click here

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 see the Documentation - Configuration Options».
