我想让 Alice（EJB A；Glassfish A）与 Bob（EJB B；Glassfish B）通信。两个 EJB 都部署在不同的 Glassfish（Glassfish A 和 Glassfish B）服务器上。通信应通过 IIOP。但是，我的实验导致 java.lang.SecurityException。问题是：为什么会这样，以及如何解决？
Alice 和 Bob 都实现了远程接口。
AliceRemote.java：
package com.fu.ba.alice.ejb;
import javax.ejb.Remote;
@Remote
public interface AliceRemote {
void callBob();
}
BobRemote.java：
package com.fu.ba.bob.ejb;
import javax.ejb.Remote;
@Remote
public interface BobRemote {
void sayHello();
}
Alice 和 Bob 的实现也很简单。
爱丽丝.java：
package com.fu.ba.alice.ejb;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import com.fu.ba.bob.ejb.BobRemote;
/**
* Session Bean implementation class Alice
*/
@Stateless(mappedName = "AliceMap")
public class Alice implements AliceRemote {
@EJB(name = "BobRemote")
private BobRemote bob;
/**
* Default constructor.
*/
public Alice() {
}
@Override
public void callBob() {
System.out.println("Hello this is Alice");
bob.sayHello();
}
}
鲍勃.java：
package com.fu.ba.bob.ejb;
import javax.ejb.Stateless;
/**
* Session Bean implementation class Bob
*/
@Stateless(mappedName = "BobMap")
public class Bob implements BobRemote {
/**
* Default constructor.
*/
public Bob() {
// TODO Auto-generated constructor stub
}
@Override
public void sayHello() {
System.out.println("Hello this is Bob");
}
}
此外，Alice 的 EJB 包括一个 ejb-jar.xml 和一个 glassfish-ejb-jar.xml 指定 IIOP 通信。
ejb-jar.xml：
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:ejb="http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd" version="3.1">
<display-name>com.fu.ba.alice.ejb </display-name>
<ejb-client-jar>com.fu.ba.alice.ejbClient.jar</ejb-client-jar>
</ejb-jar>
glassfish-ejb-jar.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-ejb-jar PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 EJB 3.1//EN" "http://glassfish.org/dtds/glassfish-ejb-jar_3_1-1.dtd">
<glassfish-ejb-jar>
<enterprise-beans>
<ejb>
<ejb-name>Alice</ejb-name>
<ejb-ref>
<ejb-ref-name>BobRemote</ejb-ref-name>
<jndi-name>corbaname:iiop:123.123.123.123:3700#java:global/com.fu.ba.bob/com.fu.ba.bob.ejb/Bob!com.fu.ba.bob.ejb.BobRemote</jndi-name>
</ejb-ref>
</ejb>
</enterprise-beans>
</glassfish-ejb-jar>
将 EJB 部署到不同的 Glassfish 服务器会导致 Bob 和 Alice 出现异常。
