Configuring OC4J-Proprietary Deployment Options on an EJB 3.0 Session Bean

You can configure OC4J-proprietary deployment options for an EJB 3.0 session bean using OC4J-proprietary annotations (see "Using Annotations") or using the orion-ejb-jar.xml file (see "Using Deployment XML").

Configuration in the orion-ejb-jar.xml file overrides the corresponding configuration made using OC4J-proprietary annotations.

Using Annotations

You can specify OC4J-proprietary deployment options for an EJB 3.0 session bean using the following OC4J-proprietary annotations:

• @StatelessDeployment: for stateless session beans.

• @StatefulDeployment: for stateful session beans.

Example 5-10 shows how to configure OC4J-proprietary deployment options for an EJB 3.0 stateless session bean using the @StatelessDeployment annotation.

For more information on @StatelessDeployment attributes, see Table A-1.

Example 5-10 @StatelessDeployment

import javax.ejb.Stateless;
import oracle.j2ee.ejb.StatelessDeployment;

@Stateless
@StatelessDeployment(
    minInstances=5,
    poolCacheTimeout=90
)
public class HelloWorldBean implements HelloWorld {
    public void sayHello(String name) {
        System.out.println("Hello "+name +" from first EJB3.0");
    }
}

Example 5-11 shows how to configure OC4J-proprietary deployment options for an EJB 3.0 stateful session bean using the @StatefulDeployment annotation.

For more information on @StatefulDeployment attributes, see Table A-1.

Example 5-11 @StatefulDeployment

import javax.ejb.Stateful
import oracle.j2ee.ejb.StatefulDeployment;

@Stateful
@StatefulDeployment(
    idletime=100
    passivateCount=3
)
public class CartBean implements Cart {
    private ArrayList items;
    ...
}

Using Deployment XML

You can specify OC4J-proprietary deployment options using the orion-ejb-jar.xml file element <session-deployment> as Example 5-12 shows.

For more information on the <session-deployment> element, see "<session-deployment>".

Example 5-12 orion-ejb-jar.xml File <session-deployment> Element
