Jian,
FYI,
<vendor>
We do support multiple containers with our EES/EJB product. Within our
context, the main
reason for deploying beans into the same container is that we only support
relationships among beans that are deployed into the same container. People
using our stuff normally start with an object model, and this model
normally has relationships among beans, and as such the model becomes a
natural
deployment package.
