问题 I can see how one can control the size of the global pool for all the stateless session beans. However, I would like to be able to have a new pool that only applies to one type of stateless bean. This way, all my stateless beans but one would be pooled from the usual slsb-strict-max-pool , and one bean would have its own pool. Is it possible to do that in JBoss EAP 6.1? 回答1: Use @org.jboss.ejb3.annotation.Pool(value="myPoolName") annotation on the EJB referencing your custom pool as defined

问题 I have a CDI bean implementation in a dependency jar file: @ApplicationScoped public class MyService { public String doSomething() {...} } In my webapp, I want to access that service via EL Expression, therefore I have to give it a @Named annotation. But I cannot add the annotation on the MyService implementation because I don't have the rights to change that code.

问题 For the JSR 356 - Java API for WebSocket i know the reference implementation is Tyrus. Are there any others? If not, then i guess Tyrus is the implementation in all Application Servers (Glassfish, JBossAS/Wildfly etc...) 回答1: As far as I know, there are a few JSR 356 Java API for WebSocket implementations besides Tyrus (the reference implementation): Apache Tomcat Jetty Undertow used by WildFly Glassfish is the Java EE reference implementation and uses Tyrus. According to my researches: IBM
