假定在A机器(设IP为192.168.1.22)上部置EJB(ejb容器为JBOSS),其上有一无状态SessionBean First,First有一个方法 public java.lang.String sayHello( java.lang.String name ),First对应的jndi-name为"First".
在B机器上调用First的sayHello方法:
package test;
import java.rmi.RemoteException;
import java.util.Date;
import java.util.Hashtable;
import javax.ejb.CreateException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
/**
* @author <a href="starfire'mailto:zzzhc0508@hotmail.com">starfire </a>

*/
public class TestFirst {
private test.FirstHome getHome() throws NamingException {
//First为jndi-name
return (test.FirstHome) getContext().lookup("First");
}
private InitialContext getContext() throws NamingException {
Hashtable props = new Hashtable();
//不同容器的INITIAL_CONTEXT_FACTORY,PROVIDER_URL可能不一样
props.put(InitialContext.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
props.put(InitialContext.PROVIDER_URL, "jnp://192.168.1.22:1099");
InitialContext initialContext = new InitialContext(props);
return initialContext;
}
public void testBean() {
try {
InitialContext context = getContext();
//context.rebind("obj", new Date());
//Object obj = context.lookup("obj");
//System.out.println(obj);
test.First myBean = getHome().create();
//--------------------------------------
//This is the place you make your calls.
System.out.println(myBean.sayHello("hc"));
} catch (RemoteException e) {
e.printStackTrace();
} catch (CreateException e) {
e.printStackTrace();
} catch (NamingException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
TestFirst test = new TestFirst();
test.testBean();
}
}
