Accurate relationship between EJB and CORBA

[zhuzhengyu]

It is said EJB begins at where CORBA leaves off and we could find many similitude:JTS is like OTS,Java naming service is like Corba Naming service,Persistence service,serialization,etc.
Now the question is:
1.if I can conclude,EJB is based on CORBA.That is to say, EJB use CORBA to build the constructure.EJB provide container as a coordinator that CORBA does not specified.EJB simplified the transaction implementation of CORBA.
2.the difference is:
a)EJB is pure java,CORBA may need IDL
b)EJB has no yellow-page service like CORBA Trader
c) does EJB has Time service ?

I also wish to find document to dipict the relationship between both

When we relate Ejb with Corba,in CORBA we need
to implement the Multi Threading concepts if we
required.Where as in Ejb the Ejb server will look
after this concept.

Programming CORBA is like buying a car with the engine in all seperate parts, which you must assemble.

EJB hides the mechanics from the application developer and lets them get on with coding their application!
