What is the difference between using an application server like oc4j and implementing Enterprise java beans from a side
and implementing my own class to work as server from the other side

The difference is a couple of million dollars of investments in development...


Basically, it is possible to do anything yourself that the application server vendor has done. That is, if you can. The application server provides you with robust/tested implementations of transaction handling, all kinds of pooling, networking, etc. If you don't need the stuff, then you might be better off starting from scratch.


If you are thinking about writing your own EJB engine, I would suggest you take a look at JBoss & other open source projects first...
