Have you had a look at StreamWriteFilter/FileRegionFilter? I think those
are the best for writing large files. Just put the one you prefer AFTER
your ProtocolCodecFilter in the filter chain. Once you've done that you
can write InputStream/FileRegion objects using IoSession.write(). I
think FileRegionFilter only exists in MINA 2.0. MINA 1.x includes the
StreamWriteFilter.

Hi
I'm brand new to MINA. I've come up with a protocol which includes file
attachments. I'm extending the CumulativeProtocolDecoder as per the
ImageDecoder example in the documentation. It works fine for small files but I
am unable to send a 1.5MB file, it never gets further than around 320 - 330k
(varies every time). Without going into too much further detail, here are some
log excerpts from my application. I log every time I enter doDecode and return
false in doDecode():

I was wondering if MINA is suited for this kind of application and if there's
any inherit size limit in CumulativeProtocolDecoder. I run this with 1GB heap
size and 256M max direct buffer size. Does anyone have any insights?
Thanks
Peter
