I just posted the API to the Asynchronous File I/O in Java framework I’ve been working on at Apache. My plan is to have some functional code posted by January 27. The initial code release will use the java.util.concurrent package to provide asynchronous operations. Support for POSIX AIO will come out soon after that. If you’re really interested in the framework, you can follow the changes in the subversion repository. Comments and suggestions should be directed to the Apache MINA mailing list.
