|I'm glad to see this is just for BMP. There are better solutions for

Yes for BMP since the container doesn't own the state (he doesn't know where
to look and such) all the container can ensure is that the state is
persisted through the "ejbStore()" calls. Now the state in memory is
synched across VM in one Tx encapsulation. A BMP finder can now work it's
jdbc or odbc.
This is a nobrainer.
For CMP, it is of course another matter altogether, but right now the
implementation of the finder is still through JDBC in databases so that we
would need the same requirement. If we have in memory maps we can query
across nodes (yeah right) then that is one thing, otherwise we are screwed.
What I am saying is that the only thing I see us having any control over is
the Tx information for example if the tx is new with finder then we can
avoid this madness.
