Obviously, that should have been:
ServletContext application =

| OpenFile.java:38: incompatible types

| required: java.io.File
| return application.getMimeType(file.getName());
And it looks like this should have been
protected String getMimeType(HttpServletRequest request, File file)
{
~ // This is a reasonable default implementation.
~ // Feel free to change it.
~ ServletContext application = request.getServletContext();
~ return application.getMimeType(file.getName());
}
...which will also fix this problem:
| OpenFile.java:92: setContentType(java.lang.String) in
| javax.servlet.ServletResponse cannot be applied to (java.io.File)
| response.setContentType(getMimeType(request, file));
Try my fixes and see what happens.
If the image does not appear, try using LiveHTTPHeaders or some other
tool to watch the HTTP request/response for the image and see what
status code is returned. Feel free to add debug logging statements to
the class to give yourself more information.
