Summary: Transfering PNG using getResponse()

OS/Version: Windows Server 2003

Hello,
within my action code I try to transfer my png files to browser using
getResponse().getOutputStream()).
protected ActionForward executeInternal() throws Exception {
FileInputStream in = null;
ServletOutputStream out = null;
try {
String sFileName = getRequest().getParameter("img");
long length = new File(sFileName).length();
getResponse().setContentType("image/png");
getResponse().setContentLength((int) length);
in = new FileInputStream(sFileName);
out = getResponse().getOutputStream();
if (length > Integer.MAX_VALUE) {
ABPLogger.getErrorLogger().severe("**File is too large");
byte[] buf = new byte[4096];
int len;
while( (len = in.read(buf)) > 0 ) {
out.write(buf, 0, len);
}
}
else {
//Read/Write out in one block!!!!
byte[] bytes = new byte[(int) length];
in.read(bytes);
out.write(bytes);
}
} catch (Exception ex) {
getErrorLogger().severe("**TomCat streaming problem!!!!!");
ex.printStackTrace();
} finally {
ABPResourceHelper.close(in);
}
return null;
}
But very often following excpetion occurs.

Within a second try it works well. What can I do to prevent this effect?
Thanks
