[jboss-jira] [JBoss JIRA] Commented: (JBAS-9416) EJB3 SFSB performace problem: parallel calls are sequenced

[ https://issues.jboss.org/browse/JBAS-9416?page=com.atlassian.jira.plugin.... ] jaikiran pai commented on JBAS-9416: ------------------------------------ That's required by spec. Session beans are meant to be thread safe. Here's what the EJB3.1 spec says in section 4.3.14: {quote} The container serializes calls to each stateful and stateless session bean instance. Most containers will support many instances of a session bean executing concurrently; however, each instance sees only a serialized sequence of method calls. .... By default, clients are allowed to make concurrent calls to a stateful session object and the container is required to serialize such concurrent requests. Note that the container never permits multi-threaded access to the actual stateful session bean instance. {quote} -- This message is automatically generated by JIRA.
