Yep, there is a specification for JavaSpace bulk operations but it’s clear from recent discussions it’s still not well known. It was released in Jini 2.1 and provides:

1. Bulk write
2. Bulk take
3. Bulk read
4. New notify method

Bulk take and write are straightforward, bulk read less so because due to the nature of reads it has to provide a streaming style of interface. And the new notify method allows you to get a copy of the Entry which triggered the event but also provides facilities for Entry’s becoming available/visible again as the result of transaction aborts etc.

The JavaDoc for JavaSpace05 is here.
