calling from a jsp page

majalitto · Post by **majalitto** » Wed Nov 19, 2003 6:04 pm

I have a jsp page where I would like to include a chart. I simple called the servlet using the image source attribute and setting it to the servlet.

<img src="/MyServlet" />

The servlet creates a chart based upon session attributes that are created. When I enter the name of the servlet in the address bar, it creates the chart. The content type in the servlet is image.png.
But if I call the servlet by using the image tag it will not appear.
Can somebody tell me what I'm doing wrong.

Did you receive an answer or find a solution?
Actually what you do looks ok. (I do quite the same (only using Struts actions) and I have no problems)
If you want you can send me your servlet and I have a look at the code.

try something like

<img src="/MyServlet/chart.png"/>

I believe IE has problems unless the name of the image is a recognizable image type.

if i use

<img src ="MyServlet">

how can i also pass parameters back to the servlet to determine which image i need to be created??

try
<img src ="MyServlet?imgType=chart1">

then in the servlet
String imgType = request.getParameter("imgType");

if(imgType.equals("chart1"))
{....
