EJB>改变sessionbean的JNDI名称 小强斋

在Jboss 中要自定义JNDI 名称，可以使用@LocalBinding 和@RemoteBinding 注释，@LocalBinding 注释指定Session Bean 的Local 接口的JNDI 名称，@RemoteBinding 注释指定Session Bean 的Remote 接口的JNDI 名称，变Session Bean 的JNDI 名称

package com.foshanshop.ejb3.impl;
import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import com.foshanshop.ejb3.LocalOperation;
import com.foshanshop.ejb3.Operation;
import org.jboss.annotation.ejb.LocalBinding;
import org.jboss.annotation.ejb.RemoteBinding;
@Stateless
@Remote ({Operation.class})
@RemoteBinding (jndiBinding="foshanshop/RemoteOperation")
@Local ({LocalOperation.class})
@LocalBinding (jndiBinding="foshanshop/LocalOperation")
public class OperationBean implements Operation, LocalOperation {
private int total = 0;
private int addresult = 0;
public int Add(int a, int b) {
addresult = a + b;
return addresult;
}
public int getResult() {
total += addresult;
return total;
}
}

在JSP 客户端调用上面EJB 的代码片断如下：
InitialContext ctx = new InitialContext(props);
Operation operation = (Operation) ctx.lookup("foshanshop/RemoteOperation");

如果你使用的是weblogic10/Sun Application Server/Glassfish，你可以使用@Stateless.mappedName()设置bean 的全局JNDI 名称，如：

@Stateless(mappedName="OperationBeanRemote")
public class OperationBean implements Operation, LocalOperation {

客户端访问EJB 的代码片断如下：

InitialContext ctx = new InitialContext(props);
Operation operation = (Operation) ctx.lookup("OperationBeanRemote#com.foshanshop.ejb3.Operation");
