|[eclipselink-users] Sequence generator - as a service|
Might be a silly/hard to understand question... How would I use EclipseLink as a means to implement sequence block pattern? What I want to do is this: a. Remote client (Flex) calls Java service do so work, amongst others it passes in an identifier (initially '0'). b. Java service uses 'sequence block' to obtain next unique identifier (not '0') when the passed in identifier is '0'. --> this would be the place where I would want to use EclipseLink <-- c. Java service performs requested work and returns the identifier, which might have been not '0' in the first place i.e. passed in at a. or initialized at b. d. Remote client (Flex) continues to call a. as long as there is work to be done. If everything is completed continues with e. e. Remote client (Flex) calls into (another) Java service to 'finalize' the operation. It passes in the not '0' identifier and other stuff. f. Java service uses not '0' identifier as the primary key (@Id) via setId() of a record to be created. Now, let us first wait and see who understands what I'm trying to do here ;-) Thanks, Jan.
