Re: [eclipselink-users] Partitioning with Spring managed data sources

[James Sutherland <jamesssss@xxxxxxxxx>]

Your code seems like it should work.

The error,
Missing partitioning policy for name [Replicate].

means you did not define a partition policy named 'Replicate'.  You need to
define this.

Include the code where you define and use this.
