RE: [Simpleweb-Support] Chunked encoding changes

[Marc N. <ma...@ke...>]

That fixed it!  Thanks Niall for your quick response.

One quick note: the simple-2.4.2.tar.gz contains an old JAR file in the =
jar directory.  I rebuilt the new one in Ant but you may want to include =
the 2.4.2 JAR in that directory for those who don't want to build it.

Thanks again,
Marc

Hi,

I have fixed the problem with the ChunkedOutputStream. The source can be =
downloaded from the following URL:

http://simpleweb.sourceforge.net/download/2.4.2/

P.S If you notice that this does not work let me know, although I have =
run several tests to make sure it correctly encodes content I may have =
missed something.

Regards,
Niall

that I changed the MonitoredOutputStream to use the =
MonitoredOutputStream.flushBytes() method instead of the =
OutputStream.flush(). In fixing this bug I must have introduced a new =
one. Ill have to run a few tests to see where the problem is, but you =
can be sure that I will release an update (2.4.2) as soon as I find it.
