EJB is good only when you really need it. If you are using container managed transaction (CMT)
for the web services operation you probably don't need ejb.

Subject: Web Service performance


In term of performance and scalability, if my business logic is a java 
class and I want to expose it as a web service.

Is it better to add an ejb and expose it as a web service (This new ejb 
merges the business API and forwards calls to the java class. It uses 
services provided by the ejb container) OR add a class which merges the 
business API and exposes this new class as a web service ?

Will webservices facade of EJB (with Axis as a soap engine) supports 
more client requests than webservices call to POJO class ?  What is the 
more scalable option ?

Thanks for your answer.
