EJB stateful session bean Count Test-优快云博客

这是根据精通ejb一书中的count stateful session bean所做，但是现在有一个问题就是这个sessionbean好像再执行过程中，没有被挂起，这样也就更加不存在什么激活了，ejbpassivate 和ejbactivate两个方法就没有被调用到，通过jboss控制传出来的信息，根本就不存在这两个方法的调用

大致代码如下所示：

本地接口countjava

package examples;
import javax.ejb.*;
import java.rmi.*;
public interface Count extends EJBObject
{
public int count() throws RemoteException;
}

home接口

package examples;
import javax.ejb.*;
import java.rmi.*;
public interface CountHome extends EJBHome
{
public Count create(int value) throws RemoteException, CreateException;
}

beanfangfa

package examples;
import javax.ejb.*;
import java.rmi.*;

public class CountBean implements SessionBean
{
public int val;

public int count()
{
System.out.println("count()....");
return ++val;
}

public void ejbCreate(int val) throws CreateException
{
this.val=val;
System.out.println("ejbCreate()");
}

public void ejbRemove()
{
System.out.println("ejbRemove()");
}

public void ejbActivate()
{
System.out.println("ejbActivate()...");
}

public void ejbPassivate()
{
System.out.println("ejbPassivate()");
}

public void setSessionContext(SessionContext ctx)
{

}

}
