A Java EE 6 project has a stateless bean CustomerSessionBean. Injecting it in a Servlet as:
and hit Ctrl+Space. This should show only the types can come here instead of the complete list.
Thanks for reporting. I can take a look on that if it's doable for NB72. There works common java editor CC so actually there would be needed (probably new) API for filtering the CC, I will speak with guys from the editor.
BTW, you can also use action ALT+Insert (Insert code action) and choose 'Call Enterprise Bean' for injecting the bean into the servlet.
