I have the following code to read blob data & display the result as an image. But I'm getting the error java.lang.IllegalStateException: getWriter() has already been called for this response.
while (rs2.next()) {
Blob image = null;
byte[] imgData = null;
j++;
qPaperOptions = rs2.getString(1);
int qDetailId = rs2.getInt(2);
image = rs2.getBlob(5);
ServletOutputStream sout = response.getOutputStream();
//o.close();
//imgData = image.getBytes(1,(int)image.length());
//Blob cnt_data=rs2.getBlob("cimg.ctn_data");
if (image != null) {
//imgData = image.getBytes(1,(int)image.length());
response.setContentType("image/gif");
InputStream in = image.getBinaryStream();
int length = (int) image.length();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
while ((length = in.read(buffer)) != -1) {
sout.write(buffer, 0, length);
}
}
}
Что я могу сделать, чтобы решить эту ошибку?
