IllegalStateException: OutputStream already obtained

[vsingr]

I am trying to display an image in my jsp. The image is a pie chart
generated dynamically. i use another jsp to generate the image and
include this in my other jsp where the image is displayed. However when
I do so I get the following exception in my console though the image
appears. Can any one help in this regard? I am also including the
snippet which shows the image generation and the include.

Thanks in advance
Sriram
The code for generating the image is
<% // Please don't add spaces at the beginning or the end of this file.
This may
//result in the graphs being not displayed on the page
correctly %><%@
page language="java" import="java.io.*,
com.trp.jvl.iiwc.BasicSession" %><%
try
{
String chartID =
request.getParameter("chartID");
//Get the binary data for the chart gif from
the session and write
//it to the output stream
BasicSession pgtCache =
(BasicSession)request.getSession().getAttribute("pgtCache");
byte [] bytes = (byte[])pgtCache.get(chartID);

if ( bytes != null )
{
response.setContentType("image/jpeg");
OutputStream outStream = null;

outStream = response.getOutputStream();
outStream.write(bytes);
outStream.flush();

}
}
catch (Exception e)
{
e.printStackTrace();
}
%>
The include happens as below
<img
src="/portfolioAnalytics/pages/portfolioAnalytics/portfolio/currentPieChart.jsp?chartID=targetChart"/>
