I am a new EJB programmer. I read some sample codes
Why in EJB web services, EJBLocalHome is used and pure EJB servlet uses
EJBHome as interface?
Thank you for all your commens

一般Home就行了，工作在远程(Servlet, JSP)这头。本地（EJB的Container这边）如果你
也想用它就通过LocalHome。

You should know the pros and cons of local and remote interfaces, right?
In the WS case, the beans needed are local, i.e. in same JVM.
In the servlet case, the servlet container and application server may
run in different JVMs. It's also possible that they are in one JVM but
the developer plan to seperate them together, or they just like remote
interface.
