ServletOutputStream

[behofmann]

I'm using the JFreeChart ChartUtilities.writeChartAsPNG to display my charts using JSPs. I'm now receiving the following errors:

java.lang.IllegalStateException: getOutputStream() has already been called for this response

java.lang.IllegalStateException: Cannot reset buffer after response has been committed

This worked fine with previous versions of Java. Now anytime I do a getOutputStream from the response object I get the above errors when trying to display my charts.

Using out.clear() and out = pageContext.pushBody() in my JSP eliminates the errors above, but I'm still having problems displaying charts from my servlet.

Any help, examples, or advice would be greatly appreciated.

Thanks,

Brandon
