The ChartUtilities class has a bunch of utility methods to encode the chart into an OutputStream (your HTTPServletResponse outputStream).

One important method is the ServletUtilities.saveChartAsPNG. There a some threads about this in the forum. Just search.

There is a chapter in the JFreeChart Developer Guide that describes how to use JFreeChart with Tomcat. You can also take a look at Richard Atkinson's demo:
