I am using jetty 6.1.23 within eclipse RAP (Rich Ajax Platform 1.3.2) and Java version 1.5. I am sending a PNG image to the browser. These are pieces of code that are causing trouble:
server side:
response.setContentType(application.getMimeType(".png"));
response.setContentLength(outputSize);
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Max-Age", 0);
ServletOutputStream servletoutputstream = response.getOutputStream();
servletoutputstream.write(imageBytes); // this throws EofException
servletoutputstream.flush();
client side:
<img src="path to the servlet that is loading the image">
The thing that's weird is that this problem does not happen all the time. It happens intermittently after we moved to production. There were no problems in our test environment. The only difference between production and our test environment is that in production environment, users are far away from our servers, while in the test environment, they are very close.
When the exception gets thrown, image does not get displayed at all at the client's browser end! What is going on? What can I do to fix it or at least have a workaround?
This is the full exception trace (I highlighted key exceptions):
