Re: [jetty-users] ByteBuffers and Jetty?

What you want for hard memory access are NativeDirectByteBuffers

These can ONLY be created from native code run through JNI.  Once created they appear like any other ByteBuffer to the JVM.

Jetty's DefaultServlet is already doing a bunch of smart things
related to mapped file buffers and such, see
(in particular parameter "useFileMappedBuffer").

If that's not enough, you need to be more explicit on what you want to do.

Finally, no matter how good the architecture and design are,
to deliver bug-free software with optimal performance and reliability,
the implementation technique must be flawless.   Victoria Livschitz
