How to configure pool size for individual Stateless beans?

adasko Apr 22, 2015 5:28 AM

We want to limit the number of concurrent request to certain EJB's. Configuring the pool size at the subsystem level is not sufficient since it affects all EJB's.

Currently we solve this by putting the request on a JMS(hornetq) queue and controlling the concurrency that way. It would be nicer to just use @Asynchronous and let the container control the concurrency.

You will have to configure a pool in the EJB3 subsystem and then refer to that pool from either the jboss-ejb3.xml deployment descriptor or via @Pool annotation on the bean. Here's an example of the jboss-ejb3.xml which configures the beans to use the pool (names) configured at the subsystem level https://github.com/wildfly/wildfly/blob/master/testsuite/integration/basic/src/test/java/org/jboss/as/test/integration/ejb/pool/override/jboss-ejb3.xml

Thank you for the quick answer.

The annotation org.jboss.ejb3.annotation.Pool does not exist in the source for EAP 6.3 and I can't find it in the WildFly repository. Is it located elsewhere or have I misunderstood?

It should be available at the following Maven co-ordinates:

<groupId>org.jboss.ejb3</groupId>
<artifactId>jboss-ejb3-ext-api</artifactId>
<version>2.1.0</version>
