默認(rèn)的JNDI命名規(guī)則前面已經(jīng)介紹過(guò)，但有些情況下需要自定義名稱(chēng)。要自定義JNDI名稱(chēng)，可以使用
@LocalBinding 和 @RemoteBinding 注釋?zhuān)?#64;LocalBinding注釋指定Session Bean的Local接口的JNDI名稱(chēng)，
@RemoteBinding注釋指定Session Bean的Remote接口的JNDI名稱(chēng)，下面的代碼展示了如何自定義JNDI名：
//author:lihuoming
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客戶端調(diào)用上面EJB的代碼片斷如下：
InitialContext ctx = new InitialContext(props);
Operation operation = (Operation) ctx.lookup("foshanshop/RemoteOperation");
