Hello,
I have a servlet that can accept file uploads. Based on quite a bit of
logging & experimenting, I found that if the entire file is not read all at
once, the following exception is being thrown in my read loop:
//open input stream from client to capture upload file
inn = new DataInputStream(request.getInputStream());
int formDataLength = request.getContentLength();
int bytesRead = 0;
int totalBytesRead = 0;
int sizeCheck = 0;
//2nd iteration here always causes exception below
while (totalBytesRead < formDataLength) {
bytesRead = inn.read(dataBytes, totalBytesRead, formDataLength);
totalBytesRead += bytesRead;
}
java.lang.IndexOutOfBoundsException

My environment is: Sun Linux JDK 1.2.2(RC1), RedHat 6.0, JServ 1.0 and
Apache 1.3.6. BTW, I am porting my servlet from NT/Apache/Allaire JRun where
the problem does not exist.
Any thoughts appreciated!
Thanks,
Greg Purpura
