User development, A new message was posted in the thread "@Serivce : Singelton EJB and reetrant calls": http://community.jboss.org/message/523254#523254 Author : Daniel Straub Profile : http://community.jboss.org/people/dastraub Message: -------------------------------------------------------------- @Service means, there is only one instance of this EJB - ok. EJB Spec. 4.7.11 says, the container must ensure that only one thread can be executing an ejb-instance (non reentrant instances). If I use an @Service, does the container serials all calls to this EJB ? Or throws an javax.ejb.ConcurrentAccessEcxeption ? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523254#523254
