I believe all of these file-upload servlets use the ServletInputStream
readLine method, implemented by the base class in the JSDK. In JSDK 2.0
there's a bug in this method (it ignores the len parameter). If you
have access to the source code (you should have the source for the O'Reilly
servlet at least) you can fix this by using your own corrected version
of the method instead, e.g. a slightly modified version of the one in
JSDK 2.1:
public int readLine(byte[] b, int off, int len, InputStream is)
throws IOException {
if (len <= 0) {
return 0;
}
int count = 0, c;
while ((c = is.read()) != -1) {
b[off++] = (byte)c;
count++;
if (c == '\n' || count == len) {
break;
}
}
return count > 0 ? count : -1;
}
Alternatively you could try the file-upload servlet with a servlet
engine that supports the Servlet API 2.1 (i.e. uses the JSDK 2.1
classes). Unfortunately there are not many that do at this point.
