Parameterized SessionCustomizer with spring (or without) [message #1002069]

I want to use the snowflake id generator created by twitter. to do this i have to configure the snowflake sequence in my sessioncustomizer with certain parameters (datacenterid, serverid, ...).

what is the best (cleanest) way to give these values to my customizers?

I allready figured out that there is no way for me to supply an actual customizer instance to eclipselink (like i can do with datasources).

I'm using spring and spring-orm to configure my persistence context, maybe this helps.

We use @Configurable for this

// because this class is instantiated by EclipseLink
@Configurable
public class EclipseLinkSessionCustomizer implements SessionCustomizer {

    @Autowired
    private WebLogicJtaTransactionManager jtaTransactionManager;

    @Override
    public void customize(Session session) throws Exception {
         ...
