Out of memory with HttpOutputstream

[Michail Popov <m....@algovision.com>]

hi...
to transfer a large amount (xMb) of data between servlets i do a POST
using
URLConnection/OutputStream
unfortunatelly the connections OutputStream is always mapped to a 
ByteArrayOutputstream by sun.net.www.protocol.http.HttpURLConnection so 
I run out of memory eventually....
a quick and dirty solution in that particular case was to extend some of
the 
sun.net.www.protocol.http and sun.net.www.http classes 
-> depends on jdk1.1 classes but didn't have to implement Http all over

has someone a better solution? maybe tomcat could register its own
HttpHandler/HttpURLConnection which provides a direct Outputstream?

ciao
michail

yes....it doesn't help if the amount of data is larger than (any)
available memory or,
with smaller pieces, a number of servlets are running this task

Have you tried looking at starting your JVM (java) with options
to boost the memory? Just a thought.
