Do web container and ejb conatiner share the same JVM

[Jane Somerfield]

When I deploy an application with .ear file,
which contains war file (JSPs and servlets) and
jar (EJBs), are the EJBs and JSPs/Servlets
running in same JVM?
If yes, I can use local
interafces of EJB2.0, otherwise, I have to use
remote interfaces.

Yes, the Web and EJB Containers for WebLogic run in the same JVM. This is true for basically every modern J2EE Server. Therefore, if you package your war with your ejbs then you will be able to access them using the local interfaces. This is also what I recommend for the majority of J2EE Deployments.

Thanks Chris.
Are they in same JVM by default? Or I have
to configure the server to make it happen?

[Chris Mathews]

Running the Web and EJB Containers in the same JVM is the default and only choice.
