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.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.
Thanks for your cooperation,
