DataOutputStream from Socket

Question

pls anytime i load large jpeg(about 10kb) images from database(Mysql) and send primitive types before it and then the picture bytes using DataOutputStream created from a socket outputstream, there occur sporadic errors sometimes but not all the time. When i reduced the picture size to about 3kb, it works fine.
Anybody with solution please!

You need to check that you are:
- Using DataOutput/InputStream the whole time, not just for the image
- You are reading the whole imagine, you cannot use available or assume that the imagine will come in a single package.
The simplest way to resolve this is to send the size of the image, before the image itself.
e.g.// to write
byte[] imageBytes;
dataOutput.writeInt(imageBytes.length);
dataOutput.write(imageByte);
// to read.
int length = dataInput.readInt();
byte[] imageByte = new byte[length];
dataInput.readFully(imageByte);
