I have a problem with a MultipartRequest, when I try to upload file. The error is: OutOfMemoryError: Java heap space. I think that the error is in the while cicle, but I don't know what's wrong. Thanks.
This is my code:
InputStream is = part.getInputStream();
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = is.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, nRead);
}
buffer.flush();
byte[] out = buffer.toByteArray();

You need to increase your heap space. If you are using eclipse you can check this link and it will show you how to increase the heap size (heap memory is the "place" where all your objects are stored)
