Hi,
I'm trying to put a graphic into an Velocity Template (vm).
The problem is that the servelt generated graphic should not be
physically saved to an temporary folder on the server. It's an
encoded jpeg stored in a bytearray. When I use the servlet path
at an 'img src'-tag the graphic is shown. But I don't have this
option here. I already tried to add the bytearray to the context
by using the method put() but then I only get the hash of the
bytearray (because of the toString() method I guess).
Here's my code:
--------------------------------------------------
public void perform(Context context, HttpServletRequest request,
HttpServletResponse response, Properties initProps,
Properties sessionProps) throws IOException {
super.perform(context, request, response);
HttpSession session =request.getSession();
double[] data = new double[7];
for (int i = 0; i < data.length; i++){
data[i] = Math.random() * 150000;
}
BarChart chart = new BarChart(600,1999,data);
response.setContentType("image/jpeg");
String strFileName = "test.jpg";
OutputStream imageout = response.getOutputStream();
imageout.write(chart.getJpegByteArray());
//context.put("trigger",chart.getJpegByteArray()); //
doesn't Work
}
----------------------------------------------
When I put the Image directly onto the response outputstream, the
picture is shown.
But ONLY the picture. I need to add some additional HTML Code around it.
Like I said
context.put() doesn't work.
Can anybody help me out?
