Describe the issue:
JBoss-specific extensions to the EJB 3.1 specification should be documented. There is for example the possibility to assign an EJB a particular transaction timeout.

Suggestions for improvement:
Add instructions how to assign a transaction timeout. It is done through the @org.jboss.ejb3.annotation.TransactionTimeout annotation, which can be added either to an EJB class (then it applies to all its methods), or a method (then it applies to this method only and overrides the effect of a @TransactionTimeout added to a class). Also, this only works for EJBs which use Container-managed transactions. Example:

@Stateless
@TransactionTimeout(value = 5, unit = TimeUnit.SECONDS)
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public class HelloBean implements HelloBeanRemote {

    @TransactionTimeout(value = 1, unit = TimeUnit.SECONDS)
    public String method1() {
        return "This method must not take more than 1 second";
    }

    public String method1() {
        return "This method must not take more than 5 seconds";
    }

}

Also please mention that the @TransactionTimeout annotation is part of the JBoss EJB3 external API and must be added as a dependency, with Maven you can do it this way:

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