why EJB is only in appserver

EJB specs are part of Java Enterprise specifications. An App server implements JEE specifications, hence an EJB container is part of an app server. An EJB utilizes several other JEE components hence it usually does not exist as stand alone container.

There were some efforts to implement EJB as standalone container (just like JSP/Servlet container), but it wasn't successful.
