stop doing that, its not your intention to load the entire filestream into the memory?! :-)
you'd be better off with streaming, so on doPost() in your servlet you could acquire a stream from the request and forward it to your outputstream on the file system, so only the internal buffer is used. IN case of huge upload I would not use tools which provides you API on byte[] level. Apache also has support for fileupload - but its is not that package which is used to access forms data (there is no streaming support) br, On 21 Jul., 16:34, rajendra dasari <rajendra.a...@gmail.com> wrote: > Hi Stefan Bachert, > > Thanks for giving suggestion, i will try on this issue as you told for > increasing memory. > > --- > > Raj. > > On Wed, Jul 21, 2010 at 7:54 PM, Stefan Bachert <stefanbach...@yahoo.de>wrote: > > > > > Hi Raj, > > > I think this will not work in general. > > On 32 Bit-System Java is limit to somewhat betwenn 1.5-2GByte memory. > > > Uploading GByte Files may excete this limit.
