How to handle multiple database connections with spring?

Hi All,

How to setup multiple database connections in spring simultaneously? How to configure it in app-config.xml ? Can someone tell me the best practise to do it?

Thanks.

you'll use it as your dataSource param for session factory

I actually don't think the poster meant a Connection Pool, but more that they have more than one database that they need to talk with.

Each Database will needs its own DataSource, and Data Access Technology bean class needed (ie SessionFactory, JdbcTemplate, EntityManagerFactory)

If you do not have a JTA Transaction manager that does two phase XA commits, then you will need a transaction manager for each database too.

Please don't duplicate post. This is an older thread and therefore probably won't get a new asnwer to it, so I am going to close it so it doesn't get resurrected again.

Thanks
