public static final void encodeServlet(Chart chart,
                                       javax.servlet.http.HttpServletResponse httpServletResponse)
                                throws ChartDataException,

                                       IOException
```
Convenience method to call from a Servlet or JSP. This method will set the appropriate mime type and then export the chart as the response. We cannot overload encode(...) as it will create a compile time dependency with the HttpServletResponse Class which will require the J2EE libraries.

Parameters:

chart -

httpServletResponse -

Throws:

ChartDataException

PropertyException

IOException

Since:

0.7
