Thread: IllegalStateException: getOutputStream() has already been called for this response

Hi All,
In Work Detail Module, 3 sub modules are--> 1.create, 2.update, 3.correct.
In CREATE Work Detail page, i ll add data and upload photos of work details in createworkdetail.jsp. photos ll stored in D:\CMSMTDP_WorkDetailImages\Anekal\n1.jpeg
In updateworkdetail.jsp & correctworkdetail.jsp(see attached screen pics) if i click on image it ll show error(refer getOutputStream already response.txt) but image is visible n pop in new window.

code for downloaded file(D:\CMSMTDP_WorkDetailImages\Anekal) & to view in jsp

public static void downloadFile(String fileName,HttpServletResponse res) throws WebException
{
ServletOutputStream outStream = null;

int bytesRead=0;
byte [] byteArray = new byte[4096];
System.out.println("filename===>"+fileName);
if(null != fileName)
{
try
{
System.out.println("inside prior to execution download");
FileInputStream is=new FileInputStream(new File(fileName));
res.setContentType("image/jpeg");
outStream = res.getOutputStream();
bytesRead = is.read(byteArray);
while (bytesRead!= -1)
{
outStream.write(byteArray, 0, bytesRead);
bytesRead = is.read(byteArray);
}

// Flush and close stream
outStream.flush();
outStream.close();
is.close();
}
catch (FileNotFoundException e)
{
//throw new WebException(e);
e.printStackTrace();
}
catch (IOException e)
{
throw new WebException(e);
}
}

}
error getting in console:
