I am not sure what you mean 'as the performance of that would not be good'. 
The way I use it, it is better. Instead of creating charts with every 
request, I only create a chart when data has changed, and save it as a name 
my html page will know. This way, I only look up an image without needing to 
create the image every time.

Of course, the servlet accessed by an image tag would be the best way to 
access a chart from struts if you needed to render the chart with every 
access, as you would not need two file operations every time (write, then 
read)
