Java – how do I get a new stateful session bean in a servlet thread?

I'm experimenting with EJB3

I want to inject a stateful session bean into a servlet so that every user accessing the servlet will get a new bean

Obviously, I can't make a bean an instance variable of a servlet because it will be shared And significant injection of local variables is not allowed

I can use the new operator to create beans, but it doesn't seem to be the right way

Is there a right way to do this? It seems that what I want to do is quite simple. After all, we want every new customer to find an empty shopping cart

Solution

You cannot use new to get a new SFSB

You usually use initialcontext to find new

MyBean bean = (MyBean) new InitialContext().lookup( name );

You will then get a reference to a specific SFSB that can be reused in the request
