Levy: Think about the deployment today of SOA on top of WebLogic. You get the full container regardless if you need all the functions of the container or not. [With modularization, you] only pick the pieces that are really necessary for the solution that we provided.

InfoWorld: Can you give an example of how somebody might pick a module of the app server as opposed to the whole product?

Levy: Well, sure. A lot of the products, the ESB (enterprise service bus), require some of the Java container services but dos not require a full JVM (Java Virtual Machine).... If you're really building full-scale applications on Java, you need [the] full WebLogic Server. But if you only need the Java container, but not the JVM that's run underneath that, then why not just take that and package that with the ESB?

InfoWorld: So when will that happen?

Levy: It's happening now.
