This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
consider two tables namely Table-A and Table-B part of two different databases namely ORACLE and MYSQL.
Now the project requirement is updating the Table-A(ORACLE) and Table-B (MYSQL) as one transaction. i.e. either update both the tables or rollback both the tables.
Now my question is how could i handle this situation using JDBC(Type-4) driver.Because i think at a time only one JDBC driver can be loaded into the JVM.
You need to use distributed (global) transactions. I have no idea if this is possible without an EJB server but, even if it is, this is one case where the set up and operation would be so much easier with such a server. An EJB server would, amongst other things, bootstrap the XA resources into a it's transaction manager, manage the connection pools via the data sources and manage the global transactions.
You will need to use XA drivers, XA-configured databases and data sources enabled for global transactions. Is there a suitable driver for MySQL?

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
